Mithridate is an ancient cure or remedy that was said to counteract the effects of poison. During the Middle Ages, people would take mithridate in the hopes of warding off the plague.
Though in past centuries it was widely considered a universal antidote to any poison, mithridate was not a scientifically proven cure but more of a mythical potion. Named for its supposed first-century Greek creator, Mithridates VI Eupator of Pontus, mithridate contained as many as 65 different ingredients. These included things like parsley, turpentine resin, and cinnamon. Mithridate was used to prevent or treat illness until the 19th century.
