Poisons

Poison was used to kill people in the end.

"here's what poison was used because nine words were not counted as a blog post".

It all depends on the type of toxin you use, you can either kill someone quietly or painfully, or quickly "I do not recommend you do this to anyone (unless you despise that person to the very core of their lifeform, and you will be put in jail".

Every poison is known but some are harder to uncover and minister treatment to said poisons, now let's begin somewhere, 

how with the most popular, Arsenic.

Mixtures of Arsenic date back to the Roman Empire, Arsenic is counted as a Meteloid in between metals and non-Metals, if it is mixed into a liquid, it will be odorless, tasteless and the symptoms resemble terrible food poisoning,

Arsenic can also be given in small doses, which will produce symptoms including weakness, confusion, paralysis, and ultimately death, once Arsenic is in the bloodstream the body mistakes it for phosphate (aka Poop), basically causing chaos around the body and stopping the 200 enzymes that help with metabolism.

Arsenic was widespread back then, but it is less popular these days because of the new technology to help detect Arsenic poisoning, around the early 19 century the method of finding Arsenic was perfected by the British chemist James Marsh, around that time if you mix Arsenic Sulfuric acid, a colorless very smelling gas named Arsine.

One Arsenic has easily detected in the usage of it declined.

Cyanide,

people tried to use Cyanide to kill Rasputin in 1916, Hydrogen Cyanide is a pale blue or colorless liquid at room temperature while Sodium cyanide and potassium Cyanide are white powder, all smell like bitter almonds.

In small doses, the human body can remove the Cyanide, which the body puts sulfur on it and it becomes Thiocyanate and it comes out as urine. Still, if it is in large doses the Cyanide prevents cells from taking oxygen. The cells start dying, symptoms of Cyanide are as follows: weakness, nausea, difficulty breathing, seizures, and more, what makes Cyanide so hard to stop is that it is so fast acting that it can kill in hours to minutes "YES MINUTES", It can be detected in blood but by the time the lab results are back the person that had Cyanide are most likely dead.

But there are secondary Indicators like extra oxygen in the blood (because the cells can't use the oxygen the person with Cyanide is breathing in, but some of these indicators can show up with other poisons, the best option is for doctors to take an educated guess and administer treatment immediacy.

Thallium.

Ingesting a single gram can kill you, Thallium Corrodes the lining of the Digestive track and causes symptoms of large amounts of pain and diarrhea, and vomiting, the Gastrointestinal symptoms last from 12- 96 hours, after 1-5 days Neuroligcan, cardiac, liver and kidney symptoms kick in, if you live long enough patents lose their hair, even though Thallium is slow acting it can be hard to detect, by the time the doctors find what it is the patent is most likely dead and the killer behind the poison has probably left the country.

Polonium-210

Polonium-210 is so strong that the lethal dose is MILIGRAMS of 210, this has only been used once in history to assassinate a former Russian spy named Alexander Litvinenko by putting Polonium-210 in his tea in London, after the tea he went to the hospital and died 3 weeks after, suffering multiple organ failures, what makes Polonium-210 so strong is that when the molecules break down Alpha radiation gets emitted, which are 2 protons and 2 neutrons, outside the body Alpha particles, can be blocked with a sheet of paper but if it is inside the body, it kills cells in the body. As far as we know this is the only case where Polonium-210 was used as a poison.

Ethylene Glycol

This is one of the components of antifreeze, as it tastes sweet and is a common poison due to the ability to be purchasable by the general public, "even if it tastes good don't drink it please, it will kill you so don't eat it or drink it", if you drink it, you may seem fine for the first few hours but the body will start breaking ethylene glycol apart to more toxic components and that in turn to grogginess and then into a Coma, the body breaks ethylene glycol into Glycolic acid, which causes a condition called "metabolic acidoses", which makes the blood in the body too acidic and the poison also makes Calcium oxalate crystals in the kidneys which physically TEAR APART the kidney tissue, most hospitals have to send a test to labs to test if someone is being poisoned by ethylene glycol and might have to wait for days until tests come back,

moral of ethylene glycol don't drink it and don't drink antifreeze.

Oleander

The Californian mortician named Timothy waters died in 1895 of what was believed of a heart attack but none suspected the poisonous plant c, it was not known that Thimothy was killed by Oleander.

Oleander refers to the genus Nerium, the small pink and purple flowers commonly found in gardens, what makes Oleander dangerous are the two potent Cardiac Glycosides, Oleanderin and Neriine, which are found in every part of the plant, it is similar to Digitalis which is a heart medication Cardiac Glycosides work by powering the ion pumps that powers heart muscle cells that which increases the force of heart muscle contraction. 

Oleander causes: cramps, vomiting, nausea, and Diarrhea, Tim spent 2 days vomiting before he died of Oleander, it was only when a rival funeral home owner bragged about killing Timothy to his informant, then doctors tested for Oleander poisoning, during an autopsy which examiners normally check for 100 compounds to find out the cause of the death of the examined, if most of the checks give back negatives for poison then the examiners may try looking at less common poisons to see the culprit of the death of the person, sadly the muder charges were dropped because the toxicologist could not confirm the results of the tests, either the reason is not oleander, or oleander is the ideal poison.
