Ver en Cuevana. Benito Arévalo is an onaya: a traditional healer in a Shipibo-Konibo community in Peruvian Amazonia. He explains something of the onaya tradition, and how he came to drink the plant medicine ayahuasca under his father's tutelage. Arévalo leads an ayahuasca ceremony for Westerners, and shares with us something of his understanding of the plants and the onaya tradition.
