“San Pedro (Trichocereus/Echinopsis pachanoi) is a thin, columnar cactus native to the Andes in South America that contains mescaline—one of the longest-studied psychedelics in the world—and the first to be labeled with the term “psychedelic.”
San Pedro has been an important element to the spiritual ceremonies of various indigenous cultures for thousands of years. In the context of these ceremonies, the San Pedro experience is known for being empathogenic (similar to MDMA) and potentially life-changing, promoting radical introspection, healing, and a sense of wonder and awe.
Traditionally, San Pedro has been consumed either on its own or with other plants in a ceremonial brew called cimora. While its use as a psychedelic is technically illegal in the US, the plant itself can be found decorating yards and gardens across the country. It can also be found in abundance at the witches’ markets of Peru (as San Pedro or Huachuma), Bolivia (as Achuma), and Ecuador (as Aguacolla or Gigantón).
Experience
San Pedro is a potent psychedelic, and a San Pedro ceremony can be intense and powerful, in both positive and negative ways. Though everyone will undergo a unique and individual experience, there are some general things you can expect.
Benefits
San Pedro has long been considered a powerful agent for healing and change, making it a central component of the shamanic ceremonies of many indigenous groups in the Americas. For many, a San Pedro journey offers deep insight into the self and the universe, giving one a greater sense of connection and spirituality. Mescaline is also known for fostering compassion and gratitude, while alleviating psychological disorders such as anxiety, depression, PTSD and addiction.
Mescaline has also been shown to help people solve problems, access their creativity, be more environmentally conscious, and improve learning. In its original use, the plant medicine was also used to treat a number of ailments, including snake bites, wounds, skin conditions, and general pain.”
