Iboga: 
The Visionary Root of African Shamanism  
by Vincent Ravalec, Mallendi, and Agnes Paicheler; Jack Cain (translator)
Inner Traditions, 2007

Iboga is a plant little-known in the U.S. outside of the modern shamanism movement and the drug culture. However, in Gabon and Cameroon, iboga is used extensively in initiatory rites to heal psychological damage and to bring the initiate into a more mature stage of life. The three authors detail what iboga is, how it is traditionally used in bwiti ceremonies, and what ramifications its use has for the pharmaceutical industry.
