The inhabitants in the vicinity of Puerto Limon, who call this 
plant ayahuasca, employ the leaves and the trunk to treat 
wounds. The vernacular name — commonly applied to an 
hallucinogenic plant (Banisteriopsis Caapi) and a preparation 
from it — suggests its possible use as an intoxicant (Schultes in 
Bot. Mus. Leafl., Harvard Univ. 23 (1972) 140). 
The alkaloid parquine has been reported from this genus 
(Raffauf, loc. cit.)
