making a drink from the leaves in hot water, they become ex- 
tremely chilled after drinking.” (Quoted in Schultes, 1966). 
Pinkley (1969) later added that the Kofans of the Putumayo also 
use the plant for high fevers and severe back pains. 
The leaves of this plant are also employed in the Iquitos 
region as a cure for bronchitis (Tina, 1969): 
‘Twelve fresh leaves of chiric sanango are crushed up, then 
squeezed and the juice mixed with a little water. A spoonful is 
drunk twice a day, in the morning and at evening during three 
days.”’ 
In contrast to the root and bark, the leaves reputedly do not 
Cause nausea. 
The Siona Indians of the Colombian Putumayo similarly 
employ Brunfelsia grandiflora as an analgesic to alleviate pain. 
They say that it has a strong numbing effect, permitting one to 
walk long distances, even if the feet ache (Langdon, 1972). In 
an isolated report, Steward and Métraux (1948) state that the 
Chama Indians of Peru take the roots of Brunfelsia grandiflora 
as an aphrodisiac. The method of use is not given. 
BRUNFELSIA GRANDIFLORA AS A HALLUCINOGEN 
This species has long been suspected of possessing narcotic 
or hallucinogenic properties (Schultes, 1966, 1967; Schultes & 
Hofmann, 1973). Herbarium labels from Peru (Tessmann 3243) 
and southern Colombia (Bristol 1364, Pinkley 420) indicate that 
the plant is a borrachera, aterm which translates ‘‘intoxicant”’ 
and which is applied to the narcotic tree Daturas and other 
plants. Friedberg (1965) and Pinkley (1969) first disclosed that 
Brunfelsia species serve as admixtures to the hallucinogenic 
drink ayahuasca or yagé prepared from Banisteriopsis Caapi. 
In 1928, the French botanist Benoist published a new 
species, Brunfelsia Tastevinii, which he claimed was used as a 
hallucinogen in the Brazilian Amazon. Benoist named the plant 
for its discoverer P. Tastevin, a missionary and anthropologist 
who reported its use among the Kachinaua tribe of the Rio
