Mescaline Mescaline Mescaline (3,4,5-trimethoxyphenethylamine) is a naturally occurring psychedelic alkaloid of the phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin. It occurs naturally in the peyote cactus ("Lophophora williamsii"), the San Pedro cactus ("Echinopsis pachanoi"), the Peruvian torch ("Echinopsis peruviana"), and other members of the Cactaceae plant family. It is also found in small amounts in certain members of the Fabaceae (bean) family, including "Acacia berlandieri". However those claims concerning Acacia species have been challenged and have been unsupported in additional analysis. Peyote has been used for at least 5,700 years by Native Americans in

The genus epithet "Stapelia" was named in honour of Johannes van Stapel, who described the first plant discovered, while the species name derives from the Latin “hirsutus”, meaning "hairy”. "Stapelia hirsuta" stems are subquadrangular and about high. Concave groves run vertically along the stems, between their four angles. This feature distinguishes "S. hirsuta" from many other "Stapelia" species with which it naturally co-occurs (e.g. "Stapelia rufa", "Stapelia engleriana"), and which typically have stems which are also subquadrangular, but
