Peyote Cactus: The peyote is a small, spineless cactus which contains psychoactive alkaloids, particularly mescaline. Peyote is a Spanish word derived from the Nahuatl peyōtl, meaning “caterpillar cocoon”, from a root peyōni, “to glisten”. Peyote is native to Mexico and southwestern Texas. It is found primarily in the Sierra Madre Occidental, the Chihuahuan Desert and in the states of Nayarit, Coahuila, Nuevo León, Tamaulipas, and San Luis Potosí among scrub. It flowers from March to May, and sometimes as late as September. The flowers are pink, with thigmotactic anthers.
Psychoactive and medicinal
In addition to psychoactive use, some Native American tribes use the plant in the belief it may have curative properties. They employ peyote for such varied ailments as toothache, pain in childbirth, fever, breast pain, skin diseases, rheumatism, diabetes, colds, and blindness. Although uncommon, use of peyote and mescaline has been associated with clinically significant effects requiring treatment.
The US Dispensary lists peyote under the name Anhalonium, and states it can be used in various preparations for neurasthenia, hysteria, and asthma.
Peyote also contains the alkaloid called hordenine (also called peyocactin)
