The Simplified Elyria Medica

The Complete Guide For All Your

Apothecary, Herbalism and Medicine Needs

Edited to include all chapters in the one post

Preface

This list of traditional and herbal medicines used since medieval times has been compiled from a variety of sources including professional knowledge/expertise, a translated version of the Materia Medica and various contemporary pharmacopoeia and pharmaceutical formularies.

While this is a comprehensive list, it is not exhaustive, and I have had to be selective with the information due to the sheer volume! On the other hand it may look excessive; however, the list is intended to be divided up among the biomes and tribes at the discretion of SBS (if they so choose), and not all tribes will have access to all resources.

I hope this may be useful in assisting the creative process for SBS and can be used in anyway, as a creative template and/or altered in anyway if SBS desires.

Chapter 1

Overview:

Generally speaking the only difference between a medicine or drug used therapeutically or recreationally and a poison or toxin is the dose.

A medicine WILL be toxic and dangerous if the dose is too high or taken to frequently, likewise many toxins, venoms and poisons from animals, plants and minerals can be and ARE used therapeutical in medicine.

Much of our existing contemporary medicine originated in nature as naturally occurring chemicals, toxins, venoms or poisons that have been extracted, isolated, purified and sometimes structurally modified to produce new drugs, which are then prepared in to pharmaceutical preparations such as tablets, injections, suspensions, eye drops, creams, ointments etc., use to treat disease and illness.

With this in mind, pretty much any naturally occurring chemical, toxins, venoms or poisons from plants and animals such as spiders, scorpions, snakes, sea anemones, fish, molluscs (sea snails, cone shell) and other venomous creatures have the potential to be used as either a poison or medicine under the right circumstances.

** Side note (feel free to skip this paragraph): Obviously, that’s an oversimplification and nothing is as straight forward as that! Other factors which are important in reality include genetic variations in metabolic enzymes, receptor or ligand polymorphisms, existing medical conditions and medications, specific conditions such as liver or kidney disease, diet and/or deficiencies, age, gender, weight, muscle mass, allergies or tolerance, route of administration, pharmaceutical formulation just to name a few.

The way in which a chemical, toxin, venom or poison may kill you, is also the way in which it can be used therapeutically. Think of it this way, the only reason why you should be taking medicine, because something is not working correctly, so you counteracting that illness with a substance that causes the opposite (normally dangerous) effect. As a general rule, plant and animal based chemicals, toxins, poisons and venoms can be divided in to the following SIMPLIFIED categories (not an exhaustive list).

**Side note: Each TYPE has multiple SUBTYPES that can be located in multiple parts of the body. This is why they can act is seemingly unrelated ways. Furthermore it is not only possible, but highly likely that a single chemical, toxin, venom or poison can also act in MULTIPLE ways. This is due to structural similarities that exist between different types. These two factors are why we have side effects:

Type 1: Sodium channel blockers: can be used as a local anaesthetic, pain killer, and treatment for heart palpitations/arrhythmias and seizures/epilepsy

Type 2: Calcium channel blockers: pain relief, blood pressure, heart rate/rhythm, seizures/epilepsy, Alzheimer’s disease/other dementias and Parkinson’s disease.

Type 3: Potassium channel blockers and immunosuppressant: can be used to treat autoimmune and inflammatory diseases such as gastrointestinal diseases (crohn’s disease, ulcerative colitis), CNS diseases (multiple sclerosis, dementia), liver (hepatitis), kidneys (nephritis), whole body/systemic disease (Lupus erythematosus), joint disease (rheumatoid arthritis), skin (psoriasis, dermatitis) and respiratory diseases such as asthma.

Type 4: Alpha receptor and Beta receptor blockers: Used to reduce blood pressure, slow heart rate, reduce force of heart contraction. They can also be used to treat prostate enlargement and eye conditions such as glaucoma.

Type 5: Alpha receptor and Beta receptor activators: These are your typical life-saving drugs used to "kick start" the heart when it has stopped or has slowed to dangerous levels, when blood pressure is dangerous low, to counteract life threatening allergic reactions (anaphylaxis), medical resuscitation and life support for patients with sepsis/blood infections/poisoning, keeping someone alive after a traumatic injury resulting in dangerous amounts of blood loss (will also require "replacement" blood or fluid), plus open then airways and stimulate breathing in respiratory illness such as asthma, which can also be life threatening condition.

Type 6: Neurochemical blockers and enhancers: Depending on what they are blocking or enhancing, they may either treat or worsen conditions such as pain, Parkinson’s disease, Alzheimer’s disease/dementia, seizures/epilepsy, depression, mania, hallucinations, and other psychological conditions such as schizophrenia.

Type 7: Platelet and Clotting factor inhibitors: Depending on whether the target is platelets or one of many clotting factors, they can be used to prevent blood clots that may cause, heart attacks, strokes and other clots/thrombi such as DVT (deep vein thrombosis).

Type 8: Antibacterial and Anticancer agents: As the name suggests, these toxins and venoms have been shown to kill infection and cancer cells because they selectively “attack” and destroy specific types of cells that they “recognise”.

Based on these categories it is pretty much possible to emulate the majority or real life, poisons, toxins, venoms and medicines. It is also perfectly acceptable to use a single type, or combine multiple types in to one substance to produce multiple therapeutic uses, side effects and/or poisons. You just need to name them!

The hard part is knowing in detail, exactly what a substance is supposed to do, how the body would normally interact with the substance (absorption, distribution, metabolism and excretion), how other substances, other diseases, differences in pharmaceutical formulation, route of administration and pretty much everything else listed in the first “Side Note” alters its initial effects.

Luckily, for a game… you can literally just make that stuff up!

It is believed to increase blood circulation so may have benefits in people with poor circulation and conditions such as Reynaud’s Phenomenon.

Could this help tribes who are not used to cold climates?

It has been known to increase the risk of bleeding by reducing the ability of the blood to clot.

Bilberry is unsafe for use in pregnancy as it strongly stimulates uterine contractions.

Birthwort: Aristolochia species:

Biome: Found almost everywhere

Therapeutic uses: Historically used as a non-specific antidote to some poisons with variable effectiveness. It was also used to ease nausea associated with pregnancy and ease childbirth, urinary tract infections and menstrual cramps.

While not carcinogenic, it may worsen certain types of breast and ovarian cancer. It is also considered hepatotoxic (damaging to the liver) to some individuals.

Black Cohosh may cause nausea, vomiting, dizziness and weight gain.

Black Cohosh also reduces the metabolism of many other drugs/compounds so may increase their efficacy, side effects and toxicity.

Black Nightshade Solanum nigrum:

Biome (tribe): Primarily found in wooded areas (Brudvir, Janoa, Kypiq)

Poison uses: Berries contain a toxic chemical that is toxic to the cardiovascular system and CNS (central nervous system), resulting in nausea, flushing, confusion, hallucinations, delirium, paralysis, coma, cardiac arrhythmias and respiratory failure.

Menthol and camphor are some of the most common ingredients in Vicks® products and many “heat” creams, ointments and liniments, along with various salicylate derivatives (see Willow). When applied vigorously, camphor produces a warming sensation to the area, while producing a cooling effect when applied gently.

Side effects and toxicity: In large doses, including on the skin, camphor is toxic causing seizures, rapid and/or irregular heart rhythm and muscle cramps/spasms.

Cannabis Cannabis sativa var. indica:

Biome (tribe): Found all over Kypiq forests because they are little stoners! (Jokes). With 12 to 13 hours of sunlight each day, it can grow almost anywhere and is well suited to wet environments (Neran, Kypiq, Janoa, To’resk, Dras, Brudvir)

Feverfew: Tanacetum parthenium (leaf):

Biome (tribe) Found almost everywhere

Therapeutic uses: Acute and chronic migraine treatment and prevention. Also general aches and pains and pain associated with arthritis.

Is known to increase the risk of bleeding in susceptible individuals, similar in severity to aspirin and willow bark, but not as severe as anticoagulants such as warfarin and other coumarin compounds.

Chapter 3

Simplified Anatomy and Physiology

Physiology

Introduction

Like the previous chapters, the aim of this chapter is to convey the overall big picture on how the organs are interconnected and the way the body works as a whole without having to delve in to excessive amounts of detail that overshadow the big picture.

The jargon: In the absence of disease, damage or drug, the body exists in a natural state of balance known as homeostasis. Everything including endogenous substances (produced by and from within the body) and exogenous substances (introduced from outside the body), exists in the body within a certain concentration range deemed to be normal for an individuals’ specific circumstances. Furthermore the functioning or performance of each organ system may also be quantified by the concentration of these substances with regard to specific reference ranges, and also be considered normal for a persons’ individual circumstances.

The explanation: So what the hell does that mean? Simply put, everything is normal and how it should be BUT an isolated value for some laboratory test is meaningless without considering the specific circumstances surrounding the person from which the laboratory test was taken. Just because a result is high, low or normal means nothing if you know nothing about the situation.

Let me give you some examples. Would you consider it abnormal for someone to have a pulse/heart rate of 150 beats per minute? Many people might automatically say “Yes”. While they may be correct, they could also be completely wrong, depending on the circumstances! Why? So this “person” may have just had a massive fright, may be in severe pain, has just run the 200 metre sprint or perhaps this is a sleeping 2 week old baby! All of which might make this value fairly normal!

What if I said an individual had a resting heart rate of 32 beats per minute! Again, many people would rush in and say “WOAH!!! That’s dangerously low!!!” Truthfully, in 99.99% of cases you would be correct, but what if I said this was the resting heart rate of Lance Armstrong? Well, that would then be considered normal… It’s still amazing, but it is absolutely normal, for him due to his level of fitness and the strength of his heart.

So context is important…..

Heart and Blood

What does the heart do?

The heart pretty much does one thing and one thing only. It pumps blood around the body. It’s actually more like 4 pumps in 1, rather than just 1 big pump. There are two smaller chambered pumps (atria) at the top of the heart and two larger chambered pumps at the base of the heart (ventricles). The blood and blood vessels are like a river system used as trade routes for your body and organs so that the blood can transport and deliver essential nutrients, vitamins, electrolytes, energy/fuel and oxygen around the body to your organs. It is this system which is also used by medicines, other drugs, poisons, toxins and venoms etc., to deliver their effects to the appropriate (and sometimes inappropriate) places in the body.

The heart receives blood which has already made its oxygen delivery to the body in the right atrium, while it receives blood which has stocked up on oxygen from the lungs again in the left atrium. The right atrium squeezes the blood in to the right ventricle which then pumps the blood to the lungs once it is full. The left atria collects the blood once it has gathered oxygen from the lungs and squeezes it in to the left ventricle which then pumps it around to the rest of the body, via the aorta (a very large thick artery), once it is full.

What happens if the heart or blood doesn’t work properly?

The heart may accumulate damage over time and when forced to work harder than intended for longer than intended. When the heart is damaged over time by disease or suddenly by traumatic injury, the main result is that blood is not pumped as efficiently. This reduces the amount of blood and essential nutrients, vitamins, electrolytes, energy/fuel and oxygen being delivered to the organs. If the blood isn’t working properly then the amount of nutrients, vitamins, electrolytes, energy/fuel and oxygen able to be transported and deliver by the blood itself is reduced. While the heart can heal, the functional deficits experienced due to the damage may be permanent. Generally speaking, the lack of required nutrients, vitamins, electrolytes, energy/fuel and oxygen being delivered around the body produces a feeling or tiredness and fatigue (but so many other things can cause this feeling as well).

One of the typical signs and symptoms associated with damage to the heart is chest pain. It doesn’t necessarily mean that damage has occurred, but may be more like a child screaming when they don’t get what they want. Either way, it is a warning sign that the heart itself is not getting enough oxygen or energy required for functioning because blood carrying oxygen, nutrients and energy is being prevented from reaching the heart due to a clot and/or cholesterol blockage, the heart is not functioning properly and unable to pump the blood efficiently enough or the blood is not able to carry enough oxygen, nutrients and energy due to disease, damage or even blood loss!

Chest pain typically occurs with increased exercise or exertion resulting in an increase in oxygen and energy requirements. The less exertion required for the pain to occur, the more serious the situation AND if pain occurs while resting it is a VERY BAD sign!! If the pain does not go away particularly when resting and/or is not relieved by appropriate medication, you may be having a heart attack (myocardial infarction), which is where the heart muscle has actually started to die because it has been starved of the necessary oxygen and energy required to function.

When heart muscle dies, scar tissue typically forms at the site. This can lead to a disruption in the electrical currents through the heart muscle resulting in an irregular heart beat (arrhythmia). The heart may beat faster or slower (rate) and/or the chambers of the heart may begin pumping at inappropriate times (rhythm). Anything which results in the heart not beating at the correct rate or with the correct rhythm results in the blood not pumping efficiently. If the heart speeds up (tachycardia), the chambers of the heart do not have enough time to fill properly, pumping less blood with each beat. If the heart beats too slowly then the blood does not circulate fast enough and if the heart chambers pump at inappropriate times, it can disrupt the flow of the blood entirely

If the atria tremble rather than squeezing and relaxing properly, it is known as either atrial fibrillation or atrial flutter. This causes blood to pool inside the chamber rather than being pumped and can result in blood clots forming in the stagnant blood. If the clot is then pumped around the body, it may cause a blockage in the leg, a blockage in the lung (pulmonary emboli), a blockage in the heart (myocardial infarction) or blockage in the brain causing stroke, brain damage and death. If a similar thing happens to either ventricle (ventricular fibrillation) and is not corrected immediately, the result is death!

Damage to the blood vessels or other organs may damage the heart by increasing blood pressure and forcing it to work harder. This may result in the chamber of the heart becoming larger due to heart muscles stretching and becoming “saggy” (systolic heart failure). The stretched, saggy muscle is then unable to effectively pump blood effectively. One of the typical signs of systolic heart failure is fluid and blood leaking in to the lungs due to the blood not flowing properly and causing a drowning sensation as the lungs fill with fluid and prevent the person from breathing. If, on the other hand, the heart muscle becomes larger and too toned, the chamber of the heart becomes too small resulting in less blood filling the chamber and being pumped with each beat (diastolic heart failure).

If the heart and/or blood do not function properly, other organs and/or the heart itself start to be affected and can result in damage to any of the organs including the heart. Furthermore if the function of other organs begins to decline, the decline itself or compensatory mechanisms by the organs, may result in further damage to any other including the heart. As you can see, this can start a chain reaction that leads to the complete failure of each and every organ ultimately death.

For information on how other organs may affect the heart and what happens when other organs become damaged, see those specific organs.

One of the last complications associated with damage to the heart is infective endocarditis. This is an infection of the heart muscle typically occurring when valves of the heart are damaged and provide a nice rough surface for bacteria (and sometimes fungus) to stick to. This is an extremely dangerous infection as it not only damages the heart but also has the potential to spread anywhere in the body through the bloodstream as well as causing septicaemia, sepsis or septic shock, which basically results in a body wide inflammatory response that causes the organs to shut down and stop working completely due to reduced blood flow.

What can cause damage to the heart?

Potential causes: In addition to injury or trauma from an accident or fight, damaged may be caused by high levels of low density lipoprotein cholesterol (L-DLC) and blood clots, but NOT high density lipoprotein cholesterol (H-DLC) which is good cholesterol. Infections, autoimmune diseases that attack the heart and other organs, high blood pressure, damage to the lungs, kidneys and liver, plus alcohol, various conventional medicines, herbal and “natural” therapies, toxins, venoms and poisons can also damage the heart just to name a few. Hi stress is also a major factor in damaging the heart.

Liver:

What does the liver do?

The liver performs several functions. The majority of the work done by the liver involves metabolism. So what is metabolism? Metabolism consists of 2 different processes. The first is catabolism which involves “breaking down” substances and the second is anabolism which involves building substances. Anabolic steroids get their name from this process because they build muscle (along with a heap of nasty and dangerous side effects if used inappropriately).

Blood vessels from your stomach and intestines carry nutrients, medication and toxins to the liver to be processed in to other substances, through either catabolism or anabolism. The liver does this so they can be eliminated from the body and/or deactivated/detoxified (medication/toxins) to stop their effects. Although toxins may damage the liver, they are not “stored” by the liver as some would have you believe. Anabolism is like putting a “cap” on a pen or needle to stop it working, or attaching a sign to the substance so that the kidneys or intestines “recognise” it, collect it and dispose of it. Catabolism on the other hand is like cutting up your credit card to stop it from working and activating the ATM.

There’s a catch! Your liver only produces a certain amount of the metabolic enzymes at any given time, for this purpose. If there is not enough for the required “work”, you end up with problems! Take alcohol, if you drink too much a toxic by-product is produced and can’t be detoxified (enzyme ran out early). That toxin then makes you sick in addition to other factors which don’t help.

The liver also metabolises fat, carbohydrates (sugar) and protein to produce energy for the body. If there is excess sugar in your blood it can store it by turning it in to glycogen and release it at another time when extra energy is required. When the liver breaks down protein, it also ends up producing a substance called urea which is released in to the blood and filtered by the kidneys (What if your kidneys don’t work?). The liver also stores some vitamins and minerals such as iron and copper. If your iron stores are low, you can end up with iron deficiency anaemia.

The last two functions of the liver are to produce clotting factors to stop you bleeding and synthesise a protein called albumin. Albumin is important for two reasons, the first is that many substances like medications bind or “stick” to it as they float through the blood stream. This essentially inactivates that substance and acts similar to a reservoir. The second reason albumin is important is that it “holds” the water in the blood stream, through a process known as oncotic pressure (colloid osmotic pressure).

What happens if the liver doesn’t work properly?

The liver may accumulate damage over time and when forced to work harder than intended for longer than intended. When the liver is damaged overtime by disease or suddenly by traumatic injury, all of these functions may be diminished or become entirely absent. Mild and short term damage to the liver may be reversible and the liver may adapt by working harder to compensate for any reduced function; however, if the damage is moderate to severe, or accumulates over a long period of time, the damage may become permanent and begin a gradual decline in to complete and permanent liver failure and death.

The typical signs and symptoms of liver damage and reduced liver function are jaundice (yellowing of the skin and eyeballs) and skin itch associated with the build-up of bilirubin, dark urine and pale faeces due to with blockage of the bile duct and ascites which is the accumulation of fluid in the abdominal cavity due to a lack of albumin and oncotic pressure.

If the liver does not function properly due to damage or injury, metabolic activity will be reduced and substances that would normally be eliminated from the body may accumulate, substances that are deactivated to stop their effects or detoxified (medication and toxins) will continue to produce an effect causing increased side effects and toxicity. Furthermore, the low albumin levels which normal bind substances like medications or toxins and poisons, result in larger concentrations in the blood stream and further increasing the side effects and toxicity already experienced with reduced metabolism.

In addition to this, lack of energy production can cause lethargy and malaise, while the reduced production of clotting factors can result in serious, life threatening haemorrhages (especially if injured). The reduction in albumin production also reduces oncotic pressure within the blood vessels and as a result fluid “leaks” from blood vessels and typically accumulates in the abdominal cavity; A condition known as ascites. The fluid continues to accumulate causing pain and producing a great environment for bacteria to cause an infection known as spontaneous bacterial peritonitis.

A classic consequence of sudden onset liver damage, spontaneous bacterial peritonitis and the accumulation of ammonia in the blood stream (from bacteria and protein metabolism) is hepatic encephalopathy. This is condition of the brain that results in neurological and psychiatric problems due to the ammonia and swelling of the brain. Since this condition affects the brain, it can affect everything causing abnormal behaviour, confusion, problems with speech, sight, swallowing, breathing, the heart, particularly slowing the heart rate, paralysis, seizures, coma and if the pressure builds too much, it can push the brain stem through the bottom of the skull killing you instantly!.

Depending on the type, location and severity of damage, other consequences may arise. For instance, if damage and scarring cause narrowing and reduced blood flow through the portal veins this can lead to high blood pressure called portal hypertension. This can then cause a condition known as oesophageal varices which occurs in much the same way that back pressure in a tube (the veins) may cause the tubing behind the blockage, to expand and bulge like blowing up a balloon. This “ballooning” effect happens in the blood vessels of a persons’ oesophagus or “food pipe” and is very dangerous, because the veins are weak and cannot expand very much resulting in a risk of rupture and bleeding to death due to the already ineffective clotting factors, so the bleeding cannot stop!!

What can cause damage to the liver?

Potential causes: In addition to injury or trauma from an accident or fight, various conventional medicines, herbal and “natural” therapies, alcohol, toxins, venoms and poisons can damage the liver. Infectious diseases such as the numerous hepatitis viruses, autoimmune diseases that may attack the organs and diseases such as Wilsons’s disease (cellular copper accumulation) and haemochromatosis (iron overload) may also cause liver damage. Too much iron causes damage as the iron storage capacity of the liver is finite, so excess of this limit results in damage. A simple infection left untreated, that results in sepsis and septic shock may cause damage to the liver (and other organs) due to reduced blood flow, oxygen and nutrient delivery.

Kidneys

What do the kidneys do?

First and foremost the kidneys function like a filter for the blood. Rather than a single filter, it might be more accurate to say it functions like a series of filters rather than just one big one. It starts very generalised by firstly removing a bulk amount of waste and other substances from the blood and then becomes more selective “fine-tuning” what to keep by reabsorption and what it ultimately gets rid of. The kidneys do this to maintain homeostasis and specific concentrations for individual substance within the blood stream and extracellular fluid (fluid surrounding the cells).

The kidney filters many substances, but not all! Some examples include water, metabolic waste products like urea, creatinine, uric acid, some drugs (not all) and their metabolites, plus electrolytes such as sodium, potassium, calcium, hydrogen and sugars (carbohydrates).

In addition to filtration, the kidneys secrete various hormones to regulate blood flow, blood pressure and blood pH (acidity) throughout the body (renin, prostaglandins, and bradykinin), to produce and mature red blood cells (erythropoietin), and influences bone mineral density by maintaining calcium, phosphorus and Vitamin D levels (1, 25-dihydroxycholecalciferol or calcitriol).

What happens if the kidneys don’t work properly?

The kidneys may accumulate damage over time and when forced to work harder than intended for longer than intended. When the kidneys are damaged overtime by disease or suddenly by traumatic injury, all of these functions may be diminished or become entirely absent. Mild and short term damage to the kidneys may be reversible and the kidneys may adapt by working harder to compensate for any functional decline; however, if the damage is moderate to severe, or accumulates over a long period of time, the damage may become permanent and begin a gradual decline in to complete and permanent kidney failure and death.

This can be explained using an over simplified example of diabetes. If the kidneys are forced to work extra hard to remove excessively high amounts of sugar from the blood, they get worn out (just like machinery). As a result, some substances are not filtered as efficiently and tend to accumulate in the body (urea, creatinine, phosphate), some are not reabsorbed as efficiently and thus filtered excessively (sodium, potassium and calcium) while other substances that wouldn’t normally be filtered, begin “slipping” through the “holes” and “cracks” resulting in excess loss and deficiency (protein). In addition to this, if kidney function becomes significantly impaired, erythropoietin cannot be produced causing a lack of red blood cells and anaemia, Vitamin D3 (Cholecalciferol) cannot be converted to its active form of Calcitriol (1, 25 dihydroxycholecalciferol) resulting in osteoporosis, low calcium and high phosphate levels, while toxic urea levels begin to accumulate along with significant abnormalities in fluid and electrolyte balance.

In the advanced stages of kidney failure symptoms include including volume overload (fluid retention, swelling and oedema), high blood pressure, anaemia, osteoporosis, plus dangerously high potassium levels affecting heart and nerve function (arrhythmia, heart failure, paralysis). Toxic blood levels of urea (uraemia), causes nausea, vomiting, an intense skin itch, damage to the nerves (neuropathy) often resulting in severe nerve pain that is extremely difficult to treat), and central nervous system abnormalities (lethargy, seizures, confusion, delirium, coma, and death). Lastly the reduced excretion of phosphate from the blood results in the accumulation of phosphate and metabolic alkalosis (blood pH increases and becomes too basic/alkaline).

What can cause damage to the kidneys?

Potential causes: Genetic diseases directly affecting the kidneys and indirect damage from other diseases such as autoimmune diseases that attack organs in general, lifestyle diseases (some genetic too) like diabetes and hypertension, infection, traumatic injury to the kidney and crush injuries to limbs, dehydration and severe loss of blood (reduced blood volume), some medication side effects and combination of certain medications together, poisons and toxins.

Lungs:

What do the lungs do?

The lungs perform several functions. Most obvious is intake and transfer of oxygen from the environment to the bloodstream. They also facilitate removal of carbon dioxide and other volatile gases, such as anaesthetics from the bloodstream at the same time, to remove potential dangerous waste products from our bodies. The lungs also supply the air required to make our vocal cords (voice box vibrate) so that we can produce sound and speech.

Breathing and removal of carbon dioxide helps to regulate the pH of the blood. As the amount of carbon dioxide in the blood increases, the pH of the blood becomes more acidic causing respiration to increase in an attempt to remove excess carbon dioxide and restore normal physiological pH to the bloodstream.

The lungs also help to maintain blood pressure by playing a role in the renin-angiotensin system (like the kidneys) where angiotensin I is converted in to angiotensin II and acts as a potent vasoconstrictor (blood vessel shrinker) within the lungs. As the blood vessels shrink, blood pressure increases.

What happens if the lungs don’t work properly?

Unlike the liver and kidneys, the regenerative capacity of the lungs is significantly less, so all but the smallest damage cannot be reversed; however, the lungs may be able to compensate for mild damage by working a little harder and breathing faster and there may or may not be any significant signs of reduced function.

When the damage becomes moderate to severe, gas exchange in the lungs is significantly reduced and increasing respiration is unable to provide adequate oxygen for the blood stream to meet functional requirements (hypoxia/hypoxaemia). The obvious signs of this are breathlessness and reduced ability to exercise. This triggers an increased heart rate (tachycardia) in an attempted to meet functional requirements by delivering the oxygen faster. Oxygen levels in the blood can become so severely reduced that people are unable to even walk a few steps without feeling exhausted and requiring constant medical grade oxygen from a canister. Too much oxygen though is dangerous as it reduces the rate of respiration and can worsen accumulation of carbon dioxide.

The reduced gas exchange in the lungs associated with severe lung damage can also result in an increased level of carbon dioxide (hypercapnia/hypercarbia) in the bloodstream. This results in decreased blood pH and acidosis (excessively acidic blood). As the level of carbon dioxide rises, it stimulates an increase in respiration (tachypnoea and hyperventilation) in an attempt to remove the excess carbon dioxide. Rising levels of carbon dioxide also trigger your heart to beat faster (tachycardia) and possibly irregularly (arrhythmia) in an attempt to speed up the removal of carbon dioxide from the bloodstream. As this worsens is can produce a sense of panic and feeling of suffocation due to the inability to get enough oxygen and eventually lead to convulsions and death if carbon dioxide levels become too high.

The increased heart rate associated with low oxygen and/or high carbon dioxide results in an increased blood pressure and means the heart has to work harder increasing the strain. If damage to the lungs results in damage to the blood vessels in the lungs, this can cause narrowing and increased blood pressure within the lungs known as pulmonary hypertension. The increased work and strain on the heart plus increased backpressure from the lungs often results in heart failure and thus a reduced ability for the heart to pump blood around the body. This then becomes a viscous cycle where reduced rate of blood flow and reduced oxygen in the blood causes the heart to work harder in an attempt to supply enough oxygen to the organs, which increases blood pressure further, increasing the stress already on the heart and worsening the heart failure resulting in a steady decline in heart function and death. Of course this only happens if declining lung function doesn’t starve you of oxygen and suffocate you to death first.

What can cause damage to the lungs?

Potential causes: Genetic diseases directly affecting the lungs such as asthma, cystic fibrosis, alpha1 antitrypsin deficiency and some forms of pulmonary hypertension, as well as indirect damage from other diseases such as autoimmune diseases that attack organs in general. Other causes include smoking, infections, some medication, natural and herbal medication side effects, poisons, toxins and chemicals.

The Simplified Brain

trust me, it’s simplified even if it doesn’t look it

What does the brain do?

In truth, the full extent of the brains function is a mystery, but it pretty much controls every bodily function. Even if the brain doesn’t directly control a specific function, you can be sure that it still influences that function by either enhancing or inhibiting the physiological mechanism which is in direct control.

The brain can be split up in to various structures and regions defined by its function and region of the body that it controls. The problem is that each structure or region of the brain may perform multiple functions and/or control multiple regions of the body as well as multiple brain regions may control or influence the same body region or function.

The Brainstem

The brainstem primarily works on a subconscious level, automating bodily functions such as breathing, body temperature, digestion, arousal (asleep or awake) and swallowing.The Medulla Oblongata is a special region of the brainstem which controls breathing, heart rate and blood pressure.

The Cerebral Cortex

The cerebral cortex can be further divided up to 4 main regions, the frontal lobe, the temporal lobe, the parietal lobe and the occipital lobe.

The Frontal Lobe

The frontal lobe (at the front of the brain) is mostly associated with thinking, reasoning and problem solving, processing emotions, personality traits and social skills, controlling speech production (not understanding spoken words though, that is another area) and voluntary movement.

Some of the main areas within the frontal lobe include Broca’s area, which control the mouth and jaw muscles to produce speech. On top of the brain sitting on the frontal lobe side of the junction between frontal lobe and parietal lobe stretching from one ear to the other is a band of neural brain cells called the primary motor cortex. This area controls voluntary movement for every single part of the body. Each little area of the body, from your big toe to your little finger, your legs, arms, eyelids and everything in between has a specific area located on this strip of brain tissue, which is used to control that specific area.

Everything immediately in front of the Primary Motor Cortex and halfway to the front of the brain is a secondary area which assists movement.

At the very front of the brain is the part of the brain which mostly controls emotions, thinking, reasoning and problem solving

The Temporal Lobe

The temporal lobe (at the side of the brain) is predominantly associated with hearing and processing auditory information including spoken words. It is also the region which controls memory and learning.

The main area(s) of the temporal lobe associated with learning and memory are the Hippocampus and Amygdala (also part of the Mesolimbic System) which share a connection. These two areas interact to first store short term memories and then transfer that information in to long term memory storage and facilitate learning. The Amygdala, located towards the middle of the brain on the temporal lobe, is more than just a memory and learning centre. It also plays a role in storing emotional information associated with memories, processing emotional information, is associated with aggressive behaviour and is linked to certain types of seizures, autism, depression, anxiety, PTSD and fear, including phobias.

The main area of the temporal lobe which processes and understanding the meaning of spoken language is Wernicke’s area which is located at the back of the temporal lobe on the border of the temporal, parietal and occipital lobes.

The Parietal Lobe

The parietal lobe (at the top back portion of the brain) is mostly in control of sensation and perception of the environment around us, including processing writing information, interpreting spatial information such as 3D shapes and the position and the orientation of our body (and others) in 3D space.

Due to the complex interaction between senses, the parietal lobe plays a role in all senses, including the sense of touch (somatosensory), taste (gustation), smell (olfaction), sight (vision) and hearing (audition).

At the junction of the frontal lobe and the parietal lobe, on the parietal lobe side of the “fissure” (the Central Sulcus) which separates the two lobes is a band of neural brain cells that stretches from one ear to the other, similar to that found in the frontal lobe. This band of neural brain cells is called the Primary Somatosensory Cortex and it is responsible for processes sensory information for each little part of the body which corresponds to a specific area on that band of brain tissue.

The Occipital Lobe

The occipital lobe (at the bottom back portion of the brain) is responsible to processing and interpreting visual information and colours from the eyes. That’s pretty much it!!

The Cerebellum

At the base of the skull under the occipital lobe sits the cerebellum, a part of the brain that looks almost like a second brain. The word “Cerebellum” literally means “little brain”. One of the main functions of the cerebellum as we understand it is fine motor control, that is fine tuning movements initiated by other parts of the brain, coordinating multiple simultaneous movements and controlling posture and balance.

The Mesolimbic System and Basal Ganglia

Right in the centre of the brain lays two interconnected regions of the brain called the Mesolimbic System and Basal Ganglia. The Mesolimbic System, also known as the “reward pathway” is an area of the brain associated with those feelings of euphoria and addiction. This area is triggered when you eat your favourite food, have sex and also snort cocaine, just to name a few.

The Basal Ganglia on the other hand is another region of the brain associated with control of voluntary movement, especially when choosing and initiating movement. Just to throw around some big words, the basal ganglia can be further divided in to the globus pallidus, ventral pallidum, substantia nigra pars compacta, substantia nigra pars reticulate, the subthalamic nucleus, the dorsal striatum which consists of the caudate nucleus and putamen and the ventral striatum consisting of the nucleus accumbens and olfactory tubercle.

If you guessed that substantia nigra literally means “black substance” well done!! It’s called this because the nerves in the area are literally black in colour.

If you think putamen is a fancy Spanglish way of calling men whores, then I am sorry to say, but it is not!

What happens if the brain doesn’t work properly?

Your brain is very sensitive to damage. The amazing thing about the brain is that although it has practically no regenerative properties to repair damage, it does have a limited ability to “rewire” itself to force different areas to control new functions. Although functionality is seldom returned completely, the younger you are the easier and more it can “rewire” but as you get older, things become more rigid and harder to change. This process is known as neural plasticity.

With that in mind, if the brain gets damaged you can expect to lose most if not all of the function controlled by the damaged area. If the area that is damaged is in a region of the brain associated with some function that is essential for life like the brainstem, then it is pretty much all over.

Damage, dysfunction or diseases of the frontal lobe is likely to be associated with personality changes, emotional instability, and an inability to concentrate, think clearly or plan. If damage occurs in the primary motor cortex, then movement may be affected in the area of the body corresponding to the position on the brain. If the damage occurs to Broca’s area, then a person will experience a reduced ability or complete inability to express themselves verbally in a condition known as Expressive Aphasia.

If damage, dysfunction or disease of Wernicke’s area (temporal lobe) occurs, then a person will be impaired or completely unable to understand written and spoken words in a condition known as Fluent or Receptive Aphasia. Damage, dysfunction or disease associated with the hippocampus, amygdala or other areas of the temporal lobe will certainly impaired memory and may be associated with personality and behaviour changes, psychiatric/mental illness such as depression and anxiety, and also seizures.

Damage, dysfunction or disease located in the left side of the parietal lobe can be associated with a reduced ability or complete inability to write (agraphia), perform mental arithmetic (acalculia), produce aphasia and an ability to recognise objects (agnosia) or specifically faces (prosopagnosia).

On the other hand, damage, dysfunction or disease located in the right side of the parietal lobe can result in a syndrome known as “contralateral neglect” where the individual is unable to perceive particular regions, or the complete LEFT side of their body due to damage to corresponding areas on the RIGHT side of the brain. This results, for instance in an individual who may get dressed, shower/wash, shave and/or groom themselves on the RIGHT side of the body, but miss the LEFT side as they do not consciously see or perceive anything on that side. Due to redundancy in the brain, RIGHT sided neglect is very rare, but can happen.

No prizes for guessing what happens with damage to the occipital lobe. You get impaired vision duh! This may manifest as total impairment or selective for colour or if associated with abnormal neural firing and seizures it may interestingly be associated with visual hallucinations.

If damage, disease or dysfunction should occur to the cerebellum, loss of coordination (asynergia), the inability to rapidly stop and start or change movement direction (adiadochokinesia), hand and movement tremors, an inability to judge distance (dysmetria) and a wide based walk or staggering (ataxic gait), a tendency to trip or fall, muscle weakness (hypotonia), slurred speech (ataxic dysarthria) and/or a rhythmic side to side oscillation of the eyes (nystagmus) often occurs. A vertical nystagmus may occur but is much rarer.

If the mesolimbic system in the brain becomes damaged, dysfunctional or diseased, an individual may experience mental and psychiatric illness such as depression, reduced ability to cope with stress, schizophrenia, behaviour and personality changes or disorders and addiction disorders.

Damage, dysfunction or disease associated with the Basal Ganglia is typically associated with Motor Neuron Disorders, Parkinson’s disease and Huntington’s chorea. For those unfamiliar with these diseases, Parkinson’s disease is characterised by difficulty moving, particular initiating movement after being stationary, tremors, gait disturbances and the like. Huntington’s chorea is the complete opposite and is associated with uncontrollable “ballistic” type movements that may happen sporadically or frequently.

What can cause damage to the brain?

Potential causes: In addition to injury or trauma from an accident or fight, infections such as meningitis, syphilis and HIV, autoimmune, genetic or other diseases which attack the brain such as Multiple Sclerosis, Parkinson’s disease, Huntington’s chorea, Alzheimer’s and other dementia’s such as Frontotemporal dementia, Pick’s disease, Dementia with Lewy Bodies and Alcoholic dementia.

Epilepsy and other seizure disorders can also cause damage to the brain as well as alcohol, stimulant drugs such as amphetamines, various other conventional medicines, herbal and “natural” therapies, toxins, venoms and poisons.

One of the main causes of damage and dysfunction of the brain is stroke which can occur due to blockage by things such as a clot or cholesterol or haemorrhage which results in bleeding on the brain and a lack of blood supply to areas of the brain downstream of the bleed area. Typically bleeding on the brain also causes seizures.

I have made the choice not to write about some systems in the body such as the endocrine or immune system because I don’t believe they will add much beyond what has already been described.

Chapter 4

Simplified Pharmacology

Part 1: Pharmacokinetics

Before I get started I wish to once again specify that this is a simplified and generalised version so there may be parts that are missing or don’t hold true 100% of the time.

Pharmacodynamics (Drug Effects and Power) is what the therapeutic or toxic substance does to the body and how it produces its effects. Pharmacokinetics (Drug Motion) is essentially the flip-side of the coin and describes what the body does to the substance in return. It is the journey the substances takes in the body from the time it is administered (given or taken), how it gets to its site of action and how the body gets rid of it over time until it is no longer present in the body.

Pharmacokinetics

When it comes to understanding therapeutic or toxic substances, Pharmacokinetics is probably the most overlooked area by everyone doctors, nurses and pharmacists included, except for all but the highest level practitioners in their area. This is because it can be very complicated and a mathematics heavy area involving physics, plus they often fail to understand its significance and importance when selecting a drug (or poison if you’re an educated assassin). It is a commonly held misconception that simply knowing what a substance can do or what it can be used for is all that is required to select the appropriate treatment or poison (I swear with the way many doctors select treatment, they are trying to poison most of their patients). This is a huge fallacy as I will explain.

A lack of understanding of pharmacokinetics and pharmacology (usually drug interactions) in general is single-handedly, the reason why many patients suffer either treatment failure or complications and harm from the very treatment which was supposed to heal them due to ignorant prescribing and administering by health professionals. Pharmacokinetics can be broken down in to the following areas:

  • Absorption

  • Distribution

  • Metabolism

  • Excretion

These factors affect everything associated with a drug or poison from:

  • Their efficacy (effectiveness) including whether or not they will even work under the given circumstances.

  • The best or most appropriate route of administration (way to take them)

  • The most appropriate dose to produce the desired magnitude of effect for the individual patient or victim’s situation based on their own specific personal factors which may alter a drugs pharmacokinetic profile.

  • How long for the drug to take effect AND how long the effect will last.

    • Influenced by:

    • The maximum concentration reached in the bloodstream or area of effect

    • The time taken to reach the maximum

    • The minimum therapeutic or toxic level

    • The time taken for half the concentration to be metabolically broken down by enzymes and/or filtered by the kidneys

  • Potential effects one substance may have on the pharmacokinetic profile of another substance.

Patient specific factors that may alter drug or poisons pharmacokinetic profile and needs to be considered include:

  • Age

  • Weight

    • Also muscle mass versus body fat

    • Body Surface Area

    • Nutritional status

  • Other drugs/poisons currently in the patients system or having been administered recently

  • Other comorbidities (current illnesses) especially kidney and liver disease because these organs specifically affect pharmacokinetics

    • Kidneys: Excretion

    • Liver: Metabolism

As you can see, there is a lot that needs to be considered and this is only the simple version. Sadly as I said previously, these factors are seldom taken in to consideration either properly or in their entirety.

Absorption

Absorption is essentially how (and how much of) the substance gets in to your bloodstream. There are many ways to get a substance in to the bloodstream, with some being more effective generally and more effective for a specific substance than others. There are also many complicated factors which affect absorption including pharmaceutical, pharmacological, chemical (structure and properties) and physiological which can limit the viable ways a substance can safely and effectively be given.

This is why some therapeutic or toxic substances can only be given orally, some can only be given intravenously and others can be given a variety of ways.

Absorption is typically considered in terms of bioavailability which is the proportion of administered substance that reaches the bloodstream.

Injections

An injection directly in to the bloodstream is considered to have a bioavailability of 100%, but injections can also be given in to other places such as muscle, skin, joint, spine and even the eye or… other parts I won’t go in to!! If it is not directly in to the bloodstream (intravenous), then the bioavailability may not be 100%.

Muscle and skin injections can be for local effect (around the injection site) or systemic effect (whole body). Unlike an intravenous injection where you get 100% of the dose instantly or however long it takes to give the injection, muscle and skin injections can be useful for prolonging the effect by enabling a small reservoir of drug to be absorbed slower over time. If the injection is for a local effect, systemic absorption needs to be considered or you risk producing unwanted side effects and/or toxic exposure.

Other injection sites are typically used to produce a local effect and minimise systemic exposure, which helps to reduce side effects, but it should always be remember that it is only minimising systemic exposure relative to the dose, so side effects and toxicity may occur due to other factors.

Examples include joint injections of gold (yes gold), potent anti-inflammatory and immune suppressive drugs for rheumatoid arthritis, spinal injections for pain relief and anaesthesia such as epidurals and an intravitreal injection in to the eyeball may be given due to certain infections.

Oral

The most common route of administration is orally. Oral administration is anything that is swallowed, or fed tiredly in to the stomach or intestines via a tube. Anything applied to the inside of the mouth is technically not considered orally administered if it is not swallowed.

Absorption from orally administration can range from 0% to 100%. Sometimes a drug with 0% bioavailability is used to produce a local effect within the gastrointestinal tract. This is often seen with drugs used to treat constipation, diarrhoea and inflammatory bowel disease (ulcerative colitis and crohn’s disease).

There is a catch though! Often the bioavailability is determined for HEALTHY individuals using specific doses with short treatment durations. This is important factor to remember because some of these conditions that are being treated can themselves affect absorption and if either the dose is increased, the dosing frequency is quicker or the duration of treatment is longer than the duration used to derive the absorption profile, this may result in an increased bioavailability and slow accumulation of the drug in the bloodstream. It doesn’t mean it will happen, but certainly needs to be considered depending on the substance and patient’s circumstances.

Thought for CoE If you are an assassin looking to poison your mark, giving too much poison may not produce better or quicker results. Even if the poison is odourless, tasteless and colourless, there is always the chance that TOO MUCH poison could cause irritation, nausea, vomiting, diarrhoea, constipation or other effect which limits the amount that gets absorbed. If you don’t know your drugs or poisons, your plans may fail, just like a healer or physician in game.

More does not mean better!! that applies to everything without exception (except Japanese Chicken Katsu Curry.. you can never have too much).

Medical conditions, drugs, poisons and other substances that cause damage or inflammation to the gastrointestinal tract (GIT) may result in the lining of the stomach and intestines becoming less of a barrier and more “porous” allowing more of the drug and/or more drugs than usual become absorbed and enter the bloodstream.

Furthermore in the case of constipation, diarrhoea or substances that cause either where the time it takes for a substance to go from mouth to bum changes, the amount of substance absorbed also changes. So a drug that under normal circumstances doesn’t get absorbed very well, may have an increased absorption during constipation, if the limiting factor is simply slower absorption. On the other hand, if there is a delay to stomach emptying which can happen in constipation or other conditions, the substance may get absorbed less, if it primary gets absorbed further down the gastrointestinal tract such as the large intestine. Furthermore drugs that are normally absorbed well may not be absorbed during episodes of diarrhoea and vomiting as they may not be given adequate time for absorption to occur.

I now realise how much I have had to think about people’s bums and tums during the course of my profession…. Eeewwwww!!!

Another factor to consider which also gets overlooked in terms absorption is surgery such as when a patient has had a portion of their stomach or bowel removed due to injury or illness such as cancer or inflammatory bowel disease.

Another CoE thought: Would it be cool if being stabbed in the abdomen altered the absorption and thus effectiveness of a drug? Maybe the inflammation and/or infection made you absorb more, so there was a temporary risk of overdosing on the meds needed to heal you? Perhaps you had surgery to remove the damaged portion of stomach or intestines?

The absorption of some substances is affected by the local pH of the stomach or intestines in two possible ways. Firstly, some drugs are ionised or dissociate in either high (alkaline) or low (acidic) pH environments. If a substance becomes ionised in a particular gastrointestinal pH, then it is far LESS likely to be passively absorbed because charged particles are hydrophilic (like to be in water) and have trouble entering the bloodstream by diffusing across the lipid (fatty) cell membranes. If physiological mechanisms exist that actively pump the drug across a membrane barrier or a channel or pore facilitates diffusion, then the ionisation of the drug will be of little consequence.

Likewise if a drug associated or recombinates (goes from separate charged ions/molecules to a single less charged molecule) in a particular pH, then passive diffusion should be facilitated unless the molecule itself has significant charges in it’s chemical structure or the combined molecule is simply too big to cross the membrane one way or another.

The second way that pH can affect absorption is purely via chemical reaction that destroys the drug by making a new substance or two. Both acids and bases can be reactive in this way. The new substance may be inactive or simply cannot be absorbed. This is why some tablets, capsules or liquid suspensions may have enteric coatings or enterically coated particles to protect it from that environment. It may also mean that the drug simply can’t be given orally and is only available as an injection or suppository!!!

Topical

The last way substances may be absorbed is by applying them directly to the surface of the skin, both externally and internally. Absorption from the skin (or mucosal) surface can be erratic, but there are specific places that offer superior absorption. Under the tongue (sublingually) and on the inside of the cheek (buccally) are two such places as these areas allow suitable drugs to enter the bloodstream directly without suffering metabolism via locally occurring enzymes or liver enzymes.

Substances can be applied topically using creams, ointments, lotions, liniments, eye drops, sprays, powders, foams, enemas, suppositories or patches (just to name a few). Many substances will either not be absorbed and not work at all (even sublingually or buccally) or only work locally in that area. This is why applying drugs to the skin is not feasible for all medication.

There are however, a small number of drugs, poisons and other substances which are exceedingly efficient at getting absorbed through the skin (anywhere) which is why it is important to know which do and do not.

Some of the drugs that are very effective at being absorbed through the skin include nicotine patches to treat nicotine addiction from smoking, hormone replacement creams and patches, glyceryl trinitrate (nitroglycerine… yes the highly volatile explosive stuff) patch, spray and sublingual tablets for heart attack and chest pain (angina) and pain killers such as fentanyl and buprenorphine.

Back in the day when industrial strength nicotine sprays were used as an insecticide, more than a few people either died or were admitted to hospital suffering heart attacks due to nicotine exposure. One unlucky S.O.B. that I know of suffered (and survived) two as his clothes were contaminated with nicotine and upon being admitted to hospital his nicotine soaked clothes were sealed up nice and tight in a plastic bag, only to cause a second heart attack when he was being discharged and put his clothes back on!! And for some trivia, I believe this is what caused the death of “Don” Vito Andolini Corleone (Marlon Brando) in the God Father I.

I digress. A blood pressure medication that is meant to work directly on the heart but doesn’t get absorbed via the skin or only works locally on the blood vessels surrounding that area is not going to be particularly effective, generally speaking (there are exceptions). Generally speaking this example would be perfectly safe; however, treating a frail old lady’s glaucoma with a beta-blocker eye drop like Timolol does have the potential to be disastrous if you are not careful. While the eye drop is applied directly to the eye, Timolol may get absorbed systemically and if this old lady were to be particularly susceptible to the effects of timolol, such as she already has low blood pressure or maybe she is on lots of other blood pressure medication then the additive effects of these small drops may be enough to make her dizzy, fall and break a hip or legs…

An important thing to note about topically applied substances, particularly with patches, is that there is a delay to both the effect of the substance and the stopping of the effect as many of the drugs initially create a reservoir within the skin before it starts being absorbed in to the bloodstream in adequate concentrations. It is due to this that even after removing the patch there is still drug in the skin reservoir that will continue to leak in to the bloodstream for some time. This is very important when switching drug/formulations and is often forgotten by everyone!

CoE thought No.3 secretly assassinating a noble with glaucoma or dry eyes by slipping a substance in to it and watching them tumble off the balcony and go splat!! Who’d suspect eye drops? The eye drops don’t have to be medicated; they may just be viscous and cause blurred vision!!

Far out, 6 pages and this is just the beginning of my “simplified” version. Moving on…

Distribution

As the name suggests, distribution is where the substances travel too in the body. Luckily, I think I can really simplify this, even though it can get very complex too.

Typically substances either prefer to stay in the bloodstream or they accumulate and get stored in to particular bodily tissues, such as skin, fat, nails, bones, muscle etc.

Typically speaking, in the absence of any disease or injury to the kidneys or liver, drugs that prefer to stay in the bloodstream are removed by the kidneys and liver a lot faster (generalisation). This means that have a shorter half-life and their effects wear off a lot sooner. On the other hand, it also means a poison that stays in the bloodstream is eliminated from the body sooner, so long as it doesn’t kill you or destroy your kidneys and/or liver first.

Those substances which get stored by the body and other tissue create a reservoir which slowly leaks back in to the bloodstream and can cause a much longer duration of effect. This becomes important when considering chronic toxicity over a long period of time, where a substance accumulates in the body and the amount leaking back in to the bloodstream becomes too high or just has additive effects with a second or third substance.

But it can have advantages. If a medication is given at the safest and most effective dose, at appropriate intervals it can mean it doesn’t have to be given very often. It only needs to be “topped up” and is able to providing therapeutic cover for a medical condition for an extended period of time and reduces the extreme fluctuations in drug concentration within the blood stream.

If this gets messed up though, it can be very difficult to correct the mistake and people can suffer extreme and prolonged side effects and toxicity. So it’s a double edged sword.

But if only it were that simple, because substances in the blood stream can also bind to other things in the bloodstream such as proteins like albumin. When they do, they also act like reservoirs which can have the same effects and those that get stored in other bodily tissues. Furthermore, if you have two substances which like to bind to the same blood component like albumin, then they can compete for a place to bind resulting in more of Drug A, more of Drug B or more of BOTH floating around in the bloodstream. This can result in unpredictable effect, side effects and toxicity.

It doesn’t end there either. If a situation or condition affects this blood component such as a disease or even malnutrition when it comes to albumin (less albumin is produced with malnutrition) there is less places for substances to bind thus resulting in increased blood concentrations and risking toxicity for some drugs. A good example of this is Digoxin, a substance found in the Foxglove plant and is used as heart medication for heart failure and atrial fibrillation often given to elderly patients who are more susceptible to HF and AF but are also more likely to be malnourished and suffer toxicity!!

Digoxin IS a life-saving medication, make no mistake, BUT it can be VERY toxic also. The Foxglove plant was used one of the poisons used in assassinations centuries ago.

I read a misleading article online that claims it is exceedingly difficult to poison someone with Foxglove…. Not if you know what you are doing!!! MWUAHAHAHA!!!!

This same sort of scenario can happen with substances that get stored in bodily tissue such as fat or muscle because different people can have different ratios of fat to muscle which can varying between two people of equal weight but different heights, different ages will have different muscle and fat mass on average, medical conditions which cause changes to either of these and/or the fact that peoples fat and muscle mass often change naturally over time, so for chronic conditions, doses of medication may have to be adjusted over time purely on this basis, without even considering factors associated with aging and other illnesses or medications they may be taking!!

Metabolism

There are hundreds if not thousands of different enzymes in the body, that are involved in drug metabolism alone, let alone general physiological metabolism. Many are produced in the liver and sent in to the bloodstream, but some exist selectively in and around various other bodily tissues/organs. While most people think of metabolism as “breaking down” a substance, it can just as easily be creating a new substance by “adding” other molecules on to it.

“Breaking down” metabolism is called catabolism while “adding” or “building” type metabolism is called anabolism (think anabolic steroids to build muscle). Similar to breaking a substance down, adding to its chemical structure will also alter its chemical, physical and pharmacological properties.

I like to think of catabolism as similar to breaking a pencil. Doing so may stop it working properly, although it may stop working completely, partially or in the end have very little difference and require multiple stages of “breaking” to stop it completely.

On the other hand I like to think of anabolism in two ways. It can be like sticking the lid on a pen thus stopping it from working, or perhaps sticking a sign on it so that it can be identified by other enzymes or bodily functions in order to stop it working and/or remove it from the body.

Easy peasy… Yeah, no!!! if only!!

In reality substances are metabolised by many enzymes, a single enzyme metabolises many substances, multiple substances can competitively compete for metabolism altering the rate and pharmacokinetic profile of its metabolism, age and the persons developmental status affects the level and effectiveness of metabolic enzymes, plus individual genetic mutations can affect how strong and effective the enzymes are, with some mutations causing a complete lack of effect OR lack of the enzyme itself, while other genetic mutations can make them super effective.

This is not all either, some drugs are called prodrugs which intrinsically have no effectiveness at all and require an enzyme to metabolise and convert them in to a second substance which IS active. Someone with an enzyme that doesn’t work or is missing may get absolutely no effect from the drug at all regardless of dose or if they have a super effective enzyme that converts the prodrug, a low or normal dose may be toxic for them as the prodrug is converted way too quickly for their body to handle in other ways.

Of course the effect of absent or super effective enzymes is also the exact opposite for your typical substances because without an effective enzyme that is used to metabolise it, it doesn’t get inactivated and removed from the body so builds up and is toxic while super effective enzymes will make these substances ineffective because they get broken down way too fast and can’t do their job!

Just when you start to get your head around that you find out that some substances, which could be anything like other drugs, food, nutritional status, herbs and even things like cigarette smoke that can alter the effectiveness of metabolic enzymes.

I’ll try to explain: Let’s simplify this to a Substance. Substance A can represent any of the above (food, another drug, herb, cigarette smoke etc).

When Substance A gets in to a person’s bloodstream either voluntarily or without their consent, Substance A may:

  • Induce one or more metabolic enzymes such as Enzyme 1:

    • This increases the effectiveness of Enzyme 1, usually by increasing the amount of it present in the bloodstream.

    • This does not occur at a constant amount though. It is proportional to the amount of Substance A present in the bloodstream at any given time, thus there is a stronger effect on Enzyme 1 soon after the initial dose, but gradually reducing over time as Substance A is inactivated or removed from the body

    • Different doses of Substance A will also have a different magnitude of effect on the induction of Enzyme 1.

    • The result of this is that Substance A may cause other substances like Substance B to be metabolised more quickly at a rate that Is proportional to the concentration present in the bloodstream (just reinforcing this).

    • Depending on whether Substance B is a normal substance or a prodrug, whether or not Substance B becomes more active or less active will determine whether its effects on the individual are larger or smaller

    • The magnitude of this effect will also be changing over time as the level of Substance A changes over time and the rate of active Substance B to inactivated Substance B becomes relatively more or less over time.

    • But Substance A may ALSO be metabolised by Enzyme 1, which would mean its own effectiveness and ability to induce Enzyme 1, thus also Enzyme 1’s ability to metabolise Substance B can be altered in unpredictable ways that are neither linear or a nice curve.

    • Add to this other factors which are also affected by plasma concentration such as binding to albumin, storage in to fat etc., and its effectiveness at inducing Enzyme 1 may be altered again, by multiple of these factors which are constantly changing with time.

But that is only part of the equation because Substance A may also:

  • Inhibit one or more metabolic enzymes, in which case it would have the exact opposite effect on Enzyme 1 as noted in the previous points.

  • Both Inhibit and Induce multiple enzymes, each of which could also act on Substance B AND/OR Substance A itself, thus creating some crazy summation of effects which is frankly impossible to predict without an individual’s genetic sequence, unlock all the mysteries of our DNA and a super computer.

  • Lastly Substance A may be affected by one or more enzymes, such as Enzyme 1 and/or Enzyme 2 which may ALSO be induced and/or inhibited by other substances such as Substance B or Substance C

As you can see, the more drugs, medications or substances etc that an individual takes the complexity increases exponentially.

I won’t repeat the previous points for inhibition of metabolic enzymes and a combination of inhibition and induction of multiple enzymes, but they serve as a template for the exact opposite effect and some combination of both.

At times like the last point, this is where Clinical Pharmacists and no one else will be the expert and even then, they are going to simplify the problem by applying a weighting to each factor, cancel out what is considered negligible effect, possibly cancel out effects which are of equal but opposing effect and have their BEST educated and professional guess. Oh and the good ones will do it all in their head!!

Truth is, it can be so complicated that no one, not a single individual on the planet could determine the outcome with 100% certainty and it will come down to an educated guess. Unfortunately this means mistakes will happen and cannot possibly be avoided in all circumstances, especially since there is still much we don’t know or understand.

Thought for CoE I think it would be great to incorporate an unknown element of randomness in to medicine and poisons based on genetics. Just like reality people may be assigned for a particular enzyme or drug a position on the normal distribution, either having a reduced effect to a substance, a normal effect to the substance or a strong, even dangerous and potentially toxic effect to a substance.

This would add in a degree of individualization of medical treatment, where you perhaps start with the average dose most people will respond to and then be required to go back to the physician, medic, healer, herbalist, pharmacologist etc., to adjust the dose for the most beneficial dose without side effects.

This would also mean that illness/debuffs etc are not cured instantly with treatment but require a “course” of treatment over time.

How would this be implemented? Not going to say it would be easy, but my thoughts would be assigning a particular genetic profile for particular drugs, not a blanket effect of reduced, average or high response, but individual settings for each drug OR to make it easy groups of drugs. Then it’s a case of implementing multiple concentrations, strengths and/or doses of each substance which is really just the same as implementing:

  • Lite healing potion

  • Healing potion

  • Strong healing potion

  • Super healing potion

Type scenario in most MMO’s…

Can it be done? Sure!! Is it feasible to do so? I hope so, but only SBS will know for sure! Fingers Crossed

Excretion or Elimination

This is simply removing substances and metabolised substances from the body. Some substances are not absorbed into the bloodstream at all and are therefore not metabolised and pooped out unchanged with either very little effect on the body or only localised effects on the gastrointestinal tract. I’d say these substances are only a small minority.

For those substances that are absorbed in to the bloodstream, most are filtered and removed by the kidneys and end up in the urine. Some are sent back to the intestines and faeces but for simplicity sake, this can be left out.

While the kidney has many other functions which I discussed briefly in the previous chapter on physiology, when it comes to excretion it is as simple as the blood being passed through millions of relatively coarse filters in the kidney. I say coarse because they are not very selective and filter many different things in order to remove bulk amounts.

It is only later as these filtered substances travel along tiny tubes in the kidneys that they start to be sorted and are either kept in the urine to be removed from the body or sent back to the blood stream because they are important for the body.

I should not that blood itself, that is the blood cells such as erythrocytes are NOT filtered and if you find blood in your urine that is definitely a bad sign!!

Blood cells remain in the blood vessels!!

Mostly it is electrolytes or bodily salts such as Sodium, Potassium, Calcium etc which are returned to the bloodstream and most foreign substances/chemicals remain in the urine, IF they are removed by the kidneys. There are certain substances, certain drugs which actually work in the kidneys by being filtered though. Any ideas which ones?

With the exception of a fairly new class of anti-diabetes medication which prevents sugar from being reabsorbed and returned to the bloodstream resulting in you passing lolly water, mostly it is diuretics, also known as fluid tablets which work directly in the kidneys. They work directly in those long tubes inside the kidney and depending on which type of diuretic that essentially works by preventing reabsorption of one of the salts. This causes the salt to accumulate and become more concentrated and effectively “trap” water in the tubes. An obvious side effect other than having to urinate a lot is the potential for salts to deplete from the body, which can be very dangerous; however, as with everything in medicine, it is a balancing act between benefits and risks and drowning in your own fluid because you don’t take your fluid tablets is certainly a bad way to go!!

Other than the kidneys, drugs can also be excreted and eliminated by the lungs, especially if it is a volatile gas such as some gaseous anaesthetics, breast milk, which is why you have to be careful if breast feeding, saliva, sweat, tears and even semen, which can be important if on chemotherapy drugs and/or taking medication which can cause birth defects as it is possible to pass on dangerous substances to your partner… but only in a small number of cases

Off the top of my head that is excretion in a nutshell however, I am somewhat sleep deprived so may have missed something

The devs will probably have a similar mechanism in the game - kinda like the way Skyrim had it's alchemy and ingredient setup. But knowing them they're probably going to have a lot of weird plant names and stuff. This'll still be amazing.

You should join NA-W and open up an apothecary!!! Aranor forever!!

Thanks guys.

I appreciate the offer Spinam, but I am an Aussie on the Oceania/APAC server already :)

Weird plant names are good :), It will mean herbalists and healers etc will have to work everything out from scratch. I am just hoping this information might serve as a template of sorts. I don't mind if names are changed, but maybe the types of side effects and mechanisms of healing and poisoning might be useful.

Skyrim is a reasonable example of a herbalism system, but I find health, disease, diagnosis, treatment and pharmaceutics (medicinal preparation) side of things it are very much neglected in games.

I would like to add some real depth to the game mechanics. I believe if you break it in to multiple simpler algorithms, you could build a far more complex and realistic system, that is very rewarding.

I hope to cover simplified disease, diagnosis with signs and symptoms and treatment algorithms in the next chapter, followed by pharmaceutics and how to prepare the medicine.

I appreciate the feedback.

Wow amazing. You must have been working on this for a while considering how much research must have gone into it.

While the write-up so far has been a relatively quick exercise when I get the time, you could say that when this topic is finished (currently working in chapters 3 and 4) it will be a very brief summary of 9 years worth of study and research.

This is a great reference for those of us RPing as herbalists/alchemists, and an idea of the types of reagents we might see in-game. The humor added is definitely appreciated.
