San Pedro
The San Pedro cactus, or huachuma, is a sacred plant in traditional medicine, revered for its healing and spiritual properties. It was believed to provide access to a higher realm of consciousness, and aiding in spiritual awakenings. The San Pedro cactus contains mescaline, a psychoactive alkaloid compound that is also found in the Peyote cactus.
​The history of San Pedro is deeply rooted in Andean culture and traditional medicine. Archaeological evidence suggests that healers used the plant for religious divination as early as 3000 years ago. The name San Pedro however is an allusion to St. Peter’s role as the "Gatekeeper to Heaven."
​
The San Pedro cactus induces a range of effects from euphoria to intense hallucinations.
​
Common effects of San Pedro include:
-
Enhanced sensory perception (sight, sound, touch)
-
Altered perception of time
-
Vivid hallucinations
-
Emotional introspection
-
Spiritual insights
​
Unlike peyote, San Pedro is generally considered to produce a more pleasant experience, with a less intense peak and fewer physical side effects. However, it can still cause nausea and vomiting, often seen as a cleansing process. The effects kick in about 1–2 hours after ingestion and peak for another 2–4 hours before tapering down for another 8 or so hours.

This cactus has held a place in the hearts of many seasoned psychonauts, shaman and spiritual seekers for a long time.
