Psilocybe villarrealiae, which is only known to a small area of Mexico

There have been calls for medical investigation of the use of synthetic and mushroom-derived psilocybin for the development of improved treatments of various mental conditions, including chronic cluster headaches, following numerous anecdotal reports of benefits. There are also studies which include reports of psilocybin mushrooms sending both obsessive-compulsive disorders ("OCD") and OCD-related clinical depression (both being widespread and debilitating mental health conditions) into complete remission immediately and for up to months at a time, compared to current medications which often have both limited efficacy and frequent undesirable side-effects.
