The Shamanic Plant Medicine series acts as an introduction to specific teacher plants used by shamans in a variety of cultures to facilitate spirit communion, healing, divination and personal discovery, and which are increasingly known, used and respected in Western society by modern shamans as a means of connecting to spirit. Named after Saint Peter, the gatekeeper to Heaven, San Pedro is used by the shamans of the Andes in ways similar to ayahuasca and for similar reasons and effects. Its close relative, peyote, is employed by the shamans of Mexico and its modern chemical equivalent, Ecstasy, has become a popular rave culture means to trance and bliss states. Awareness of San Pedro is spreading rapidly in the West and the plant is likely to become more utilised than ayahuasca in the near future.
