Rio Tigre and Beyond: The Amazon Jungle Medicine of Manual Cordova-Rios
"The most interesting part of the book is that which deals with the intake of a hallucinogenic compound called ‘ayahuasca’...It is at this point that the narrative becomes a priceless revelation."—Carlos Castaneda,Los Angeles Times"Many experiences and happenings in the story might strain the credulity of all who have not lived themselves amongst Indians in primitive Amazon societies."—Richard Evans Schultes, Harvard Museum
