Psilocin and psilocybine are indole alkaloids obtained from the sacred Mexican mushroom (teonanácatl), Psilocybe mexicana (Agaricaceae). In the UK, psilocybine is present in the indigenous mushroom Psilocybe semilanceata (magic mushroom; liberty cap). Psilocybine is also present in other species of mushrooms including Stropharia cubensis and Conocybe spp. Psilocybine has hallucinogenic and sympathomimetic properties similar to those of lysergide. It is less potent than lysergide and its hallucinogenic effects last for up to 6 hours. There is evidence to suggest that psilocybine is converted to the active form psilocin in the body. It has no therapeutic use.
