The Puinave Indians, some of whom have migrated 
into the Apaporis basin, call this treelet yoom-dd-ha and 
rasp the bark into chicha to impart to it a rather peppery 
taste. It is recommended also as a febrifugal tea.

The Barasana Indians boil the leaves of this bushy 
treelet with the bark of Destictella racemosa and Mar- 
tinclla obovata to make one of their arrow poisons. 
Amongst the related Makunas of the same area, who 
know this plant as wey-gazw-76-mee’-h6, it is apparently not
