Kambo isn't a plant at all — it is a secretion from the Giant Monkey Frog (Phyllomedusa bicolor), harvested without harming the frog, and it is one of the oldest cleansing traditions in the Amazon. Tribes across the region — including the Matsés, Katukina, and Yawanawá — have used it for generations, traditionally before hunts, before difficult seasons, or simply as a periodic reset.
A Kambo session is short — usually 20 to 40 minutes — and always led by an experienced practitioner. A few small, superficial marks are made on the skin, and the Kambo is applied there. Most people experience a fast, intense physical response: a racing heart, flushing, sweating, and often vomiting, which the tradition regards as the point — a genuine physical purge. It passes quickly, and most people describe what follows as unusually clear, light, and calm.
Kambo is not part of the standard retreat price. It is available as an optional add-on when appropriate, and it is something you can raise during your inquiry.
