Although it is generally considered poisonous, deaths are extremely rare, and it is consumed as a food in parts of Europe, Asia, and North America after parboiling. Amanita muscaria is now primarily famed for its hallucinogenic properties, with its main psychoactive constituent being the compound muscimol.
