Edible Uses

None known

Medicinal

Hallucinogen. The stem is scraped, placed in a large pot, boiled all day, and then strained and boiled further, after which the decoction is drunk. Said to induce a comatose state the effects of which are long-lasting (24 hours or longer). Overdoses are said to be fatal. Used much less frequently than Banisteriopsis and on an individual, rather than communal, basis. Nevertheless, its use is considered to be a significant aspect of shamanistic training and knowledge[
