Among the Kubeo Indians, who call this plant ko-ma ‘-ma, the 
leaves were formerly burned to make an ash mixed with 
powdered leaves of coca (Erythroxylon Coca Lam. var Ipadu 
Plowman). They also mix the dried leaves powdered with farifia 
to ingest when there is blood in the stool. The leaves are alkaloid 
negative with a Dragendorff spot test.
