The bark, scraped from the buttress roots and boiled, pro- 
vides a tea which is often employed, as in the case of 
Monopteryx angustifolia, to expel intestinal worms. The 
Kuripako name of the tree is ow-wei’-na.

Garcia-Barriga (loc. cit., 2 (1975) 54) reports that the Indians 
of the lower Piraparana (the Barasana tribe) make their hal- 
lucinogenic drink from the stems of this vine. It is known locally 
as yage. 
VOCHYSIACEAE

The Kabuyari Indians call this tree ka-ho-gaw. The bark is 
said to be an ingredient of one type of arrow poison prepared by 
the nomadic Maku Indians of the Rio Piraparana. The other two 
ingredients could not be ascertained beyond the fact that one 
was a leaf, the other a reddish berry. The arrow poison is made 
quickly by the Maku who use it for hunting small birds. 
The chemistry of the Vochysiaceae has hardly been investi- 
gated. (Gibbs, loc. cit. 3 (1974) 1677).
