The Kubeos call this tree po-ham-bo'-raek; the Tukanos, 
sé-ne-'no. Both peoples employ the fresh bark resin in treating 
skin sores. 
There appears to be a rather generalized use of the bark resin 
of various species of Virola to alleviate or cure fungal infec- 
tions of the skin and to hasten the healing of wounds (Schultes 
and Holmstedt in Lloydia 34 (1971) 61-78).

The Tikunas of the region of Leticia, Colombia, indicate that 
this species is toxic, but they no longer have a use for it. 
Forero (/oc. cit., 28) reports that the seeds and roots of some 
species of Rourea have been used as dog poisons, source of the 
Brazilian vernacular name mata-cachorro.
