Baeocystin

Baeocystin is a mushroom alkaloid and analog of the psychedelic hallucinogenic drug psilocybin, a tryptamine derivative. It is found as a minor compound in most psychoactive mushrooms together with psilocybin, norbaeocystin, and psilocin. Little information exists with regard to human pharmacology, but a dosage of 10mg is reported to produce entheogenic effects.

First isolated from the mushroom Psilocybe baeocystis, baeocystin is a demethylated derivative of psilocybin.
