The Sibundoy avail themselves of biawvi in two ways. 
First: they may purchase a bottle of prepared biawit from 
a Sibundoy or Santiagueno medicine-man in the Valley 
of Sibundoy. Several natives of the valley who know 
where to gather the plant materials in the eastern low- 
lands arid how to prepare the drug engage in this com- 
merce. They sell it by the liter for five to ten pesos. 
Second: in cases of severe or prolonged illness, one of 
these medicine-men (tatmbwa, biaxtt pormayd) is paid, 
usually in kind or in labor, to diagnose the disease (sokan) 
while intoxicated with dravit. On these occasions, mem- 
bers of the patient’s family and one or more friends of the 
medicine-man may also take the drink. Thus, while the 
uses of biawti by medicine-men to diagnose disease and 
‘“*to study medicine’ are considered the more important 
by the ‘Sibundoy and are the central subject of this re- 
port, a majority of the men and many of the women 
have also taken Jiavii several times in their lives and for 
other purposes. 
Biaxn intoxication is sought for a variety of reasons 
outside of the medical sphere. A Sibundoy separated 
from his family while travelling may take it to relieve 
his loneliness and, as he says, transport himself to their
