Psilocybe aztecorum is still used ceremonially by the indigenous people of Oaxaca, and by Nahua people in the Popocatépetl region, although this usage is gradually diminishing. Traditional folk healers, or curanderos, maintain familiarity with psychoactive mushrooms (and other mind-altering plants used in ceremonial rituals), and diagnose illnesses by having the client ingest the mushrooms. One Mixe curandero initiation ritual involves ingestion of mushrooms following a period of abstinence from talking, sexual intercourse, and all foods except nuts for three days, whereupon the individual goes up to a mountain, subsists on nothing but a little honey, and prays to God for the power to heal.
