psilocin

hallucinogenic principles contained in certain mushrooms (notably two Mexican species, Psilocybe mexicana and Stropharia cubensis). Hallucinogenic mushrooms used in religious ceremonies by the Indians of Mexico were considered sacred and were called "god's flesh" by the Aztecs. In the 1950s the active principles psilocin and psilocybin were isolated from the Mexican mushrooms. They are not used in modern medicine
