CactiKnown for their psychoactive properties when ingested, mescaline containing cacti are used worldwide as an entheogen and supplement to various transcendence practices, including meditation, psychonautics, and psychedelic psychotherapy. Mescaline containing cacti have a long history of ritualistic and medicinal uses in the ancient world.
MescalineMescaline or 3,4,5-trimethoxyphenethylamine is a naturally occurring psychedelic alkaloid, known for its hallucinogenic effects similar 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 in a number of other members of the Cactaceae plant family.
Lophophora williamsii (Peyote)
Lophophora williamsii, better known as Peyote, is a small, spineless cactus that contains mescaline. Native North Americans are likely to have used peyote, often for spiritual purposes, for at least 5,500 years. It flowers from March through May, and sometimes as late as September.
Trichocereus pachanoi (San Pedro)
Echinopsis pachanoi (syn. Trichocereus pachanoi), commonly known as San Pedro, is a fast-growing cactus native to Ecuador and Peru. The tallest recorded specimen was 12.2 metres (40 ft) tall. It has a long history of being used in Andean traditional medicine.
Trichocereus peruvianus (Peruvian Torch)
Trichocereus peruvianus (Peruvian Torch) is a fast-growing cactus native to the western slope of the Andes in Peru. It is closely related to the San Pedro cactus. It contains the psychoactive alkaloid mescaline as well as other alkaloids.
