Peyote San Pedro (Mescaline)


  • Visionary plant medicines such as San Pedro can be unique in speed and intensity.
  • In the space of a few hours, we may experience emotions, dimensions, and beings that we didn’t even know existed.
  • The tendency in the West is to approach ethnobotanical plants with the belief that good intentions are enough to guarantee good results.
  • However, often ignored is the fact that in some ways these plants have their own rules and without an understanding of these rules, the journey can be fraught with peril and danger. -High Existence

There are many cacti in several genera that produce mescaline and similar phenethylamines in varying amounts. Cacti with a history of human use include Peyote (Lophophora williamsii), San Pedro (Trichocereus/Echinopsis pachanoi), Peruvian Torch (Trichocereus peruvianus/Echinopsis peruviana), Bolivian Torch (Trichocereus bridgesii/Echinopsis lageniformis), and Trichocereus/Echinopsis scopulicola. Mescaline also occurs in other common cacti in trace amounts. The concentration of mescaline and other alkaloids varies considerably between between species and individual plants. Other alkaloids found in psychedelic cacti include 3,4-dimethoxyphenethylamine, 4-hydroxy-3-methoxyphenethylamine, 3-hydroxy-4,5-dimethoxyphenethylamine, 4-hydroxy-3,5-dimethoxyphenethylamine, anhalonidine, anhalinine, hordenine, tyramine, and 3-methoxytyramine. The green skin of the cactus is where the majority of psychoactive alkaloids are located. Psychonautwiki
