Ecuapor: Dureno, Rio Aguarico, Napo. ‘‘Cultivated in village; also 
grows in forest not far from rivers.’’ February 7, 1966. H.V. Pinkley 105. 
The whole plant (including the bulb) is boiled and steeped to 
prepare an emetic tea. Pinkley reports that the Kofans, who 
call the plant kon-si-ahipa-cho, believe that this decoction 
enables them to attain greater accuracy in using the blow gun. 
Apparently no chemical investigations of Eucharis have 
been published.
