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
Marah (plant) bubbles. It is likely that the substance enters the fish's circulation through the gill arches where only a single-cell epithelium separates the water from the animal’s red blood cells. The affected fish float to the surface. Like many medicinal plants, at least some "Marah" species are toxic if ingested and deaths have been reported from ingesting them. Seeds of "Marah fabaceus" have been reported as being hallucinogenic. Marah (plant) Marah (the manroots, wild cucumbers, or cucumber gourds) are flowering plants in the gourd family (Cucurbitaceae), native to western North America. They are also commonly called Old man in the ground.
