The natives of the lower Rio Piraparana prepare a 
weak type of curare by boiling together for four or five 
hours the bark of Tetrapteris mucronata and of Strychnos 
Erichsonti R. Schomb. (Schultes et Cabrera 16770). 
Tetrapteris mucronata is said to be ‘employed by the 
Karaparana tribe in preparing yajé’ (Schultes et Cabrera 
12107). In this connection, it is of interest to note the 
report of the narcotic use of a species of Tetrapteris, 7. 
methystica (Schultes et Lopez 10184), in the Rio Negro 
basin of Brazil (Schultes, R. E. in Bot. Mus. Leafl.,

The leaves of Tetrapteris silvatica are burned by the 
Makuna Indians, and the ashes, mixed with any oil or 
grease, are applied to what appear to be fungal patches 
on the skin. The Makunas refer to this vine as ¢fee-mee- 
a-mee-see-ma and recognize its very close relationship 
with the following species, Tetrapteris styloptera.
