A bezoar is a stone taken from the stomach of a goat and it will save you from most poisons

Attendance: What is The difference between Monkshood and Wolfbane?

a bezoar is a stonelike mass taken from the stomach of a goat that acts as an antidote to most poisons, but does not work on everything. This is the reason why bezoars are used in the preparation of the Antidote to Common Poisons. This object is usually made of hair, plant fiber, or similar indigestible matter that stays in the gut of an animal and forms a hard ball or "stone"

Bezoars are undigested clumps of matter that accummulate inside a digestive system, similar to a cat's hairballs. They are used in Chinese herbology, and are claimed to remove toxins from the body. The word "bezoar" may come from the Persian pâdzahr (پادزهر), which literally means "protection from poison."
