Psilocybe samuiensis: The Ultimate Mushroom Guide
About The Psilocybe samuiensis Mushroom
Psilocybe samuiensis is a popular variant of Psilocybe cubensis that is strictly found on the island of Koh Samui in Thailand, where it received its’ namesake, as well as at Angkor Wat in Cambodia. The rarity or restricted range of this mushroom makes it quite the special treat in the Western world. Often confused for more genetic P. cubensis strains, P. samuiensis is considerably stronger and more effective, with many ranking it as a moderate to high potency. Despite their small stature, Thai mushrooms are known to exhibit full-on effects including “intensely visual experiences” according to famed mycologist Jochen Gartz because of the higher concentrations of psychedelic or hallucinogenic material that can be found growing on this powerful strain. The combination of psilocybin, as well as high levels of psilocin along with smaller amounts of baeocystin, can be attributed to the high associated with this Thai delicacy.
Analysed by HPLC and TLC, psilocybin and psilocin in the fruit bodies ranged from 0.023–0.90% (dry weight) and 0.05–0.81%, respectively. Baeocystin was also detected at a concentration of 0.01–0.05%.
Other names: Koh Samui or Thai (Thailand).
