In 1999, three molecular biologists travelled to the Peruvian Amazon to see whether they could obtain bio-molecular information in the visions they had in sessions orchestrated by an indigenous shaman. They had no previous experience of ayahuasca shamanism or of the Amazon, though they did have an interest in alternative healing traditions and shamanism. Their age ranged from the late-30s to mid-60s. One worked as a scientist in an American genomics company. Another was a professor at a French University and a member of the National Center for Scientific Research (CNRS). The third taught in a Swiss University and was a director of a research laboratory.
