Diplopterys cabrerana (syn. Banisteriopsis rusbyana) is a South American rainforest vine, commonly known as Chaliponga, Chagropanga and, in parts of Ecuador, Chacruna. It is found in the Amazonian lowlands of Brazil, Colombia, Ecuador and Peru. Chaliponga is a common admixture of the entheogenic tea Ayahuasca, and is rich in tryptamines such as DMT and 5-MeO-DMT.
