"Today’s hipster creatives and entrepreneurs are hardly the first generation to partake of ayahuasca, according to archaeologists who have discovered traces of the powerfully hallucinogenic potion in a 1,000-year-old leather bundle buried in a cave in the Bolivian Andes.

"Led by University of California, Berkeley, archaeologist Melanie Miller, a chemical analysis of a pouch made from three fox snouts sewn together tested positive for at least five plant-based psychoactive substances. They included dimethyltryptamine (DMT) and harmine, key active compounds in ayahuasca, a mind-blowing brew commonly associated with the Amazon jungle.

“This is the first evidence of ancient South Americans potentially combining different medicinal plants to produce a powerful substance like ayahuasca,” said Miller, a researcher with UC Berkeley’s Archaeological Research Facility who uses chemistry and various technologies to study how ancient humans lived.

"She is lead author of the study, published today (Monday, May 6) in the journal Proceedings of the National Academy of Sciences.

"Miller’s analysis of a scraping from the fox-snout pouch and a plant sample found in the ritual bundle — via liquid chromatography tandem mass spectrometry — turned up trace amounts of bufotenine, DMT, harmine, cocaine and benzoylecgonine. Various combinations of these substances produce powerful, mind-altering hallucinations.

"The discovery adds to a growing body of evidence of ritualistic psychotropic plant use going back millennia, said Miller, a postdoctoral fellow at the University of Otago in New Zealand who conducted the research during her doctoral studies at UC Berkeley.

“Our findings support the idea that people have been using these powerful plants for at least 1,000 years, combining them to go on a psychedelic journey, and that ayahuasca use may have roots in antiquity,” said Miller.

"The remarkably well-preserved ritual bundle was found by archaeologists at 13,000-foot elevations in the Lipez Altiplano region of southwestern Bolivia, where llamas and alpacas roam. The leather kit dates back to the pre-Inca Tiwanaku civilization, which dominated the southern Andean highlands from about 550 to 950 A.D.

"In addition to the fox-snout pouch, the leather bundle contained intricately carved wooden “snuffing tablets” and a “snuffing tube” with human hair braids attached, for snorting intoxicants; llama bone spatulas; a colorful woven textile strip and dried plant material. All the objects were in good shape, due to the arid conditions of the Andean highlands.

"Though the cave where the artifacts were found appeared to be a burial site, an excavation did not turn up human remains. Moreover, the plants found in the bundle do not grow at those altitudes, suggesting the bundle’s owner may have been a traveling shaman or another expert in the rituals of psychotropic plant use, or someone who was part of an extensive medicinal plant trading network."
