Psilocybin

Psilocybe mushrooms, psilocybin & psilocin

Psilocybin is a naturally occurring compound found in members of the Psilocybe mushroom genus. While the psychoactive and medicinal properties of Psilocybe mushrooms are most often associated with psilocybin, but psilocin, the active metabolite of psilocybin, is actually responsible for these effects.

Clinical research on psilocybin has only recently garnered momentum, with the FDA recently approving Phase 2b trials for the treatment of treatment-resistant depression (TRD). Psilocybin has shown efficacy in the treatment of TRD, cluster-headaches, anxiety & depression associated with terminal illness, and drug addiction.
