About Peyote


Lophophora williamsii , is a small, spineless cactus. It is native to southwestern Texas and through Mexico. It is found primarily in the Chihuahuan desert and in the states of Tamaulipas and San Luis Potosi among scrub, especially where there is limestone.

It is well known for its psychoactive alkaloids, particularly mescaline. It is used world wide as an entheogen, and supplement to various transcendence practices, including meditation, psychonautics, and psychedelic psychotherapy. Peyote has a long history of ritualistic and medicinal use by indigenous Americans. It flowers from March through May, and sometimes as late as September. The flowers are pink, with thigmotactic anthers .

The cactus flowers sporadically, producing small pink fruit. The seeds are small and black, requiring hot and humid conditions to germinate. Peyote contains a large spectrum of phenethylamine alkaloids, of which the principal one is mescaline. The mescaline content of Lophophora williamsii is about 0.4% fresh and 3-6% dried. Peyote is extremely slow growing. Cultivated specimens grow considerably faster, sometimes taking less than three years to go from seedling to mature flowering adult. More rapid growth can be achieved by grafting Peyote onto mature San Pedro root stock.

The top of the cactus that grows above ground, also referred to as the crown, consists of disc-shaped buttons that are cut above the roots and sometimes dried. When done properly, the top of the root will form a callus and the root will not rot. When poor harvesting techniques are used, however, the entire plant dies. Currently in South Texas, peyote grows naturally but has been over-harvested, to the point that the state has listed it as an endangered species. The buttons are generally chewed, or boiled in water to produce a psychoactive tea. Peyote is extremely bitter, and most people are nauseated before they feel the onset of the psychoactive effects.

L. williamsii is native to southern North America, mainly distributed in Mexico. In the United States it grows in southern Texas. In Mexico it grows in the states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas in the north to San Luis Potosi and Zacatecas. It is primarily found at elevations of 100 to 1500 m and exceptionally up to 1900 metres in the Chihuahuan desert, but is also present in the more mild climate of the state of Tamaulipas. Its habitat is primarily in desert scrub, particularly thorn scrub in Tamaulipas. It is most common on or near limestone hills.

The effective dose for mescaline is 200–500 mg, equivalent to about 5 g of dried peyote. The effects last about 10 to 12 hours. Peyote is reported to trigger states of "deep introspection and insight" that have been described as being of a metaphysical or spiritual nature. At times, these can be accompanied by rich visual or auditory effects .

In addition to psychoactive use, Native Americans used the plant for its curative properties. They employed peyote to treat such varied ailments as toothache, pain in childbirth, fever, breast pain, skin diseases, rheumatism, diabetes, colds, and blindness. The U.S. Dispensatory lists peyote under the name Anhalonium, and states it can be used in various preparations for neurasthenia, hysteria and asthma. Screening for antimicrobial activity of peyote extracts in various solvents showed positive microbial inhibition. The principal antibiotic agent, a water-soluble crystalline substance separated from an ethanol extract of the plant, was given the name peyocactin.

In the same study, mice were used for preliminary animal toxicity tests and protection studies to determine the degree of the inhibitory action of peyocactin against normally fatal infections with the bacterium Staphylococcus aureus. In every case, the mice that had been given a peyocactin extract survived, while those in the control group died within 60 hours after infection. Peyocactin proved effective against 18 strains of penicillin-resistant Staphylococcus aureus, several other bacteria, and a fungus.

The flesh may also be applied topically to promote milk production .

A 2005 paper published in Biological Psychiatry outlines research into peyote use conducted by Dr. John Halpern. He found that peyote users scored significantly better than non-users on the "general positive affect" and "psychological well-being" measures of the Rand Mental Health Inventory , a standard instrument used to diagnose psychological problems and determine overall mental health. By contrast, alcohol abusers did significantly worse than the control group in all measures of the RMHI.
