San Pedro


San Pedro, also known as Huachuma, is a tall and slender cactus native to the Andes Mountains of South America. It has been used for centuries in traditional shamanic and healing rituals, primarily in Peru and Ecuador. The cactus contains mescaline, a psychoactive compound, which is responsible for its effects on the human mind and body.

  • Aguacolla
  • Giganton
  • Abuelo or Abuelito


San Pedro is typically consumed by preparing a tea or drink from the cactus. The experience can last for 8-12 hours, during which users may have intense perceptual and spiritual experiences. It’s often described as a journey or a voyage of self-discovery, with vivid visual and auditory hallucinations, altered states of consciousness, and a deep sense of connection to nature and the universe.

How to

  • Brewed as a Tea:
    • The cactus is often cut into small pieces, boiled in water for several hours, and then strained to make a tea.
    • The boiling process is repeated several times to extract the active compounds.
  • Consumed Raw or Dried:
    • Some people consume the cactus raw or dry it and then eat it.
    • Drying the cactus can concentrate its active compounds.
  • Capsules or Powdered Form:
    • The dried cactus can be ground into powder and placed in capsules for oral consumption.
    • This method can provide a more controlled dosage but still varies significantly in potency.
  • Alcoholic Extracts:
    • Some prepare extracts using alcohol to pull out the psychoactive compounds from the cactus.
    • This method is less common and can be more potent.
