The seven thousand Guambianos, who dwell in the 
western part of the Departamento del Cauca, use coca 
magically in those reservations economically most ad- 
vanced (Quizg6 and Guambia) and in Ambal6 as a dietary 
supplement, but naturally with magical connotations. 
Coca cultivation has decreased appreciably. The prepara- 
tion of the leaves is the same as amongst the Paez (50). 
Sibundoy: linguistic group Koche, according to Ortiz 
(26b). 
The Sibundoy Indians, speaking Kamsa, live in the 
eastern half of the Valley of Sibundoy. 
In their magico-therapeutic rites, they make use of a 
number of solanaceous plants: Datura candida, D. san- 
guinea and D. dolichocarpa. Fach of these species of 
Datura has its special native name. There are further, 
according to Barclay and to Schultes, bizarre forms of 
these species with deformities due probably to virus- 
infection, each of which the Indians recognize as a dif- 
ferent ‘“‘kind’’ of borrachero and each destined for a 
specific magico-therapeutic use. The Sibundoy also pos- 
sess another curious solanaceous drug, an endemic of 
their high, mountain-girt valley: Methysticodendron 
A mesianum. 
The use of these highly dangerous solanaceous narco- 
tics is restricted to the medicine-men who employ them 
for divination, prophecy and therapy. The intoxicating 
effects, which may reach the point of delirium, some- 
times last up to several days, with periods of utter un- 
consciousness. 
Only the leaves are used in preparing the intoxicating 
drink, the infusion taking from thirty minutes to one 
hour to prepare. The medicine-men never imbibe the 
liquid all at once, delaying the drinking ceremonially 
over a two or three hour period. In the case of Methy-
