Scientific name: Diplopterys cabrerana.
Chagropanga, chalipanga, oco-yajé or yajé-uco is a species of flowering plant, a South American jungle vine of the genus Diplopterys, of the family Malpighiaceae. Not to be confused with Rusbyan Banisteriosis, with which it was associated in studies by Richard Evans Schultes and in the W3Tropics archives of the Missouri Botanical Garden. Bronwen Gates made a distinction between the two species in 1982.
Together with yagé (Banisteriopsis caapi), they make up the main ingredients for the decoction of an entheogenic drink used in indigenous Amazonian and Andean shamanic rituals (ayahuasca) in the tropical areas of South America. The other plant with entheogenic properties is Psychotria. viridis, which is more common in indigenous communities of Peru and Bolivia, while cabrerana is more common in Ecuador and Colombia. Both species are rich in dimethyltryptamine (N, N-DMT), an endogenous tryptamine present in some plant and animal species, including humans. D. cabrerana additionally produces 5-MeO-DMT, a less common analogous structure.
