"The Indians of the Colombian Vaupés roast the seeds for food. A Puinave medicine man reported that a gummy decoction of the bark is employed externally as hot as possible to reduce swellings caused by muscular injury or torn tendons. Persistent rumors maintain that the leaves are sometimes added to the hallucinogenic drink caapi (Banisteriopsis caapi), but this information has not been confirmed.

"In view of the limited number of aboriginal uses of this gymnosperm in the Americas, the following report from Surinam is of interest. The Tirio Indians employ a decoction of the crushed plant as a wash for treating headaches, and the Wayanas use the water from this liana for treating weakness, thinness and loss of appetite. The Wyana name is kwe-i ah-ku-wah nu-pah meaning 'shaman devil spirit,' indicating presumably some other use for, or association with, witchcraft" (Schultes and Raffauf 1990).
