Psilocybin is a natural psychoactive compound in certain species of mushrooms, commonly referred to as “magic mushrooms” or “psychedelic mushrooms.” Over 100 species of mushrooms are known to contain psilocybin or its derivative psilocin, with the most well-known species including: Psilocybe cubensis, Psilocybe semilanceata, and Psilocybe azurescens. Recent studies have shown potential therapeutic effects to micro dosing with psilocybin, though more research is needed.
