About Huachuma
(Also known as San Pedro)
Huachuma, also referred to as San Pedro, is a psychoactive cactus native to the Andes in South America. It has a long history of ceremonial use in Indigenous traditions, particularly in Peru and surrounding regions. Its main psychoactive compound is mescaline.
In some shamanic and Indigenous traditions, Huachuma is regarded as a plant teacher, associated with healing, connection and spiritual insight.
What are the effects and what can you expect?
Huachuma experiences vary widely. Many people describe openness, warmth and connection with nature, themselves and the people around them. Colours, sounds and physical sensations may become more vivid, and ordinary things can suddenly feel striking or meaningful.
Compared with Ayahuasca, Huachuma is often described as more outward-facing, embodied and grounded, with less emphasis on visions. The experience tends to develop gradually. Some people find clarity, playfulness or gratitude; others meet difficult emotions, confusion, physical discomfort or stretches in which very little seems to happen.
It can also have a spiritual quality: a sense of awe, of sacredness, of being connected to something larger. Others experience similar effects without understanding them in spiritual terms. Some people describe a temporary quieting of the usual inner commentary or sense of “me”, sometimes referred to as a dissolution of the ego.
The effects can last up to 12 hours.
Physical effects may include nausea, changes in body temperature, increased heart rate and blood pressure, and sometimes vomiting.
Why Huachuma after Ayahuasca?

In our 4-day retreat, the Huachuma ceremony takes place after two Ayahuasca ceremonies. That is a deliberate part of the way we have structured it.
After two Ayahuasca ceremonies there can be a lot to take in. Rather than treating Huachuma as simply a third psychedelic experience, we see the day as a different part of the retreat: it takes place during the day, with room for
nature, music, movement, conversation and silence.
By then the group often no longer feels like a group of strangers, which can make the day feel open and intimate. For some, it also becomes a natural transition from the intensity of the nights towards being back in the world.
Sometimes things that arose during Ayahuasca feel different in the light of the Huachuma day. Sometimes new perspectives emerge.
And sometimes it is simply a beautiful day spent together, without anything that needs to be understood or resolved.
We don’t see Huachuma as something that necessarily completes an Ayahuasca experience or ensures its integration.
It is a different medicine, with a different character, and one we value as the final ceremony of our 4-day retreat.
