San Pedro (Echinopsis pachanoi)
Huachuma is a revered plant teacher by many tribes in South America dating back to 2,000 years. In Peru, the sacred cactus is referred to as “Father teacher” where Ayhuasca is “Mother teacher”. Pedro is similar to Peyote in that they both contain mescaline however they are unique in their own as all plants are. Research shows mescaline binds the serotonin receptors and stimulates the dopamine receptors. The mescaline in Pedro, is a phenethylamine and is chemically related to MDMA [ecstasy], while LSD, DMT [the main compound in ayahuasca] and psilocybin [the main compound in mushrooms] are in the tryptamine family. Mescaline is unique among the major hallucinogens in that it is a phenethylamine.
San Pedro can produce visions just like ayahuasca can… micro-dosing it has the feel-good happiness of MDMA, with a shroom-like quality of feeling like a child while at the same time being slightly less scary, less jarring, and more loving than either aya or mushrooms.
Mescaline itself is nontoxic. And, while there are few studies done on huachuma itself, a Harvard Medical School studythat investigated the long-term effects of regular peyote use among members of the Native American Church found “no evidence of psychological or cognitive deficits” at all.
