Abstract
This invention relates to the extraction of psychoactive compounds from psilocybin fungus for use in medicine. Raw psilocybin fungus is dried and ground. The solvent used for extraction is a lower aliphatic alcohol, water, a hydro-alcohol mixture, an acidic hydro-alcohol mixture, or an alkaline hydro-alcohol mixture. The extraction slurry is filtered and pH-adjusted if necessary. The solvent is then partially evaporated, or completely evaporated with water added back, to form a concentrated slurry. The concentrated slurry is then standardized to provide a known concentration of the psychoactive alkaloids that have been extracted. The standardized slurry may then be dried to result in a powdered psilocybin mushroom extract with a precisely defined purity.
