Poisoning in Old Rome was one of the most common ways of killing, while poaching as a way of killing culminated during the Renaissance with the Borgia family, primarily with their member Lukrecija, who is believed to have killed hundreds of children to try out new poison.
Food is a common cause of poisoning, both intentional and accidental. For these accidental poisoning, the most commonly responsible are microorganisms, primarily bacteria and their toxins. Although such poisoning is mostly harmless and just rather unpleasant to poisoned, it can sometimes end up with death. Therefore, inflammable or damaged cans could potentially be a biological weapon. Clostridium botulinum is a bacterium that often lives in canned foods and produces the most toxic poison known to humans – botulinum (the toxin strength is estimated according to the dose it needs to kill, that is, the deadly dose is smaller, the poison is stronger).
How much botulinum is a strong poison, illustrates the fact that a large spoon of botulinum would suffice to kill more than a billion people. It is considered that an Iraqi terrorist group possesses an amount of botulinum sufficient to kill all the people on Earth three times.
The amount of botulinum injected directly into the vein, sufficient to kill one person, an average weight of 70 kg is 0.0000001 grams (10-7 grams). The next death is painful and painful, with the paralysis of all the muscles in the body, and the person dies of choking due to the muscle paralysis needed to breathe.
Yet, as 500 years ago, one of the first toxicologists, Paracelzus, every substance and medicine and poison, only the dose is the deciding factor. Similar to botulinum. Its commercial name is known to most people, and this is Botox®. Small amounts of botulinum, ie Botox®, are injected into the skin by injections, thus paralyzing the mummy muscles responsible for the movements that would lead to wrinkles. In addition, Botox® is also used for increased sweating because it blocks the sweat glands, as well as strabism (shyness, rancidity,).
