Sacred Plants: Mescaline
In this episode of our sacred plants season, we explore mescaline, the natural compound found in cacti like the peyote of Mexico and the southern U.S. and the San Pedro (huachuma) of the Andes. We break down what these plants look like, where they grow, and how mescaline works in the brain, from synesthesia and kaleidoscopic visions to why it isn’t considered addictive. Plus, a very strange 1983 experiment involving cats!
We also explore how these cacti were used for around 5,700 years, including the Wixárika (Huichol) origin story of three goddesses who journey to the sacred desert of Wirikuta, and the central role women play in peyote traditions.
