Wolfsbane, nicknamed “the queen of poisons”, is one of the world’s most dangerous killer plants and is a member of the Buttercup family. Commonly known as Leopard’s Bane, Woman’s Bane or Devil’s Helmet, these perennial plants are native to mountainous regions of the northern hemisphere and contain a very large quantity of a poison called Alkaloid Pseudaconitine. The poison is so effective the Ainu people of Japan used it for hunting by putting it on the tips of their arrowheads.
If a small dose is ingested, symptoms like burning in the limbs and abdomen will immediately set in, but if exposed large doses of the toxin, death will occur within 2-6 hours. In older times, poison was extracted from the plant and used to kill wolves, hence the name Wolfsbane.
