About Psilocybin

Psilocybin is a hallucinogenic indole of the tryptamine family. It is produced by hundreds of species of fungi, including those of the genus Psilocybe, such as Psilocybe cubensis and Psilocybe semilanceata, and has also been reportedly isolated from about a dozen other genera. Collectively known as psilocybin mushrooms, these are commonly called "boomers," "sacred mushrooms," "magic mushrooms," or more simply "shrooms." Possession, and in some cases usage, of psilocybin or psilocin has been outlawed in most countries across the globe. Proponents of its usage consider it to be an entheogen and a tool to supplement various types of practices for transcendence, including in meditation, psychonautics, and psychedelic psychotherapy. The intensity and duration of entheogenic effects of psilocybin mushrooms are highly variable, depending on species or cultivar of mushrooms, dosage, individual physiology, and set and setting.

Once ingested, psilocybin is rapidly metabolised to psilocin, which then acts as a partial agonist at the 5-HT2A and 5-HT1A serotonin receptors in the brain. The mind-altering effects of psilocybin typically last anywhere from 3 to 8 hours; however, to individuals under the influence of psilocybin, the effects may seem to last much longer, since the drug can distort the perception of time.

The American ethnologist R. Gordon Wasson and his wife discovered that the ancient religious practices of the Indians in a remote village of Mexico included ingestion of mushrooms. In 1957, they published a Life magazine article , where they described the occurrence of hallucinatory experiences during these rituals. They were accompanied on a later expedition by the French mycologist Roger Heim, director of the Muséum national d'histoire naturelle, when it was possible to identify several of the fungi as Psilocybe species. Heim was able to successfully cultivate the mushroom in France, and sent samples to the Swiss chemist Albert Hofmann for analysis. Hofmann, who had previously discovered and experimented with LSD, was the first to recognize the importance and chemical structure of the pure compounds he called psilocybin and psilocin. Leading a research group that was able to isolate and identify the compounds from Psilocybe mexicana, Hofmann was aided in the discovery process by his willingness to ingest mushroom extracts. He and his colleagues later synthesized a number of compounds chemically related to the naturally occurring psilocybin:
