This dissertation opens the doorway to the recognition in the United States of the potential for the reversal of organic illness through the use of the entheogen ayahuasca, an agent known as a “Divine Intelligence”. This sacred drink has been used for millennia by over seventy indigenous groups in the Upper Amazon and Orinoco basin for healing, shamanic journeys and divination. (Luna, 2000) It is also referred to as yage, caapi, daime, hoasca, natem, nishi, along with numerous other names.
