2. Aconite
The second place on our list of untraceable drugs and poisons that cause death in humans goes to Aconite that is also known as wolf’s bane, evil’s helmet and queen of poisons. Pretty illustrious names if you ask us. Although small doses of aconite are used in medicine, in larger quantities it becomes a deadly poison. Symptoms of poisoning are almost instant, and death will occur immediately with an increased dose. Initial signs are diarrhea and vomiting followed by irregular heartbeat and numbness in the limbs. The death occurs due to heart and respiratory system paralysis. In autopsy, the main cause of death will be described as asphyxiation. Although aconite is surrounded by the “untraceable” myth, it can be traceable if the examiner knows what to look for. One of the cases of aconite poisoning happened a few years ago in Britain when a woman tried to poison her former lover. Needless to say, she was caught.
