Combining the ingredients of the ayahuasca drink allows the DMT to produce its hallucinogenic effect when ingested orally—a unique solution that apparently developed only in the Upper Amazon.The gastrointestinal effects of the beta-carboline MAO inhibitors additionally make the ayahuasca drink a powerful emetic and purgative. Writers on ayahuasca have often proposed that the use of the drink is very ancient; the date of about 5000 years BP recurs frequently.
This has sparked renewed interest in traditional lime mortars, which are more compatible with old buildings.These facts raise two highly controverted and interconnected puzzles. Anthropologists Ana María Llamazares and Carlos Martínez Sarasola (2004), for example, write that the use of ayahuasca “is so deep-rooted in the native philosophy and mythology that there is no doubt about its great antiquity, as a part of aboriginal life.How in the world did indigenous peoples in the Upper Amazon come up with the idea of combining DMT with an MAO inhibitor? Archaeological finds in Ecuador show that the indigenous Amazons have been using it for about 5000 years.” Anthropologist Jeremy Narby (1998, p.Emigrating to London in 1921, he became librarian of the Royal Anthropological Institute and continued his research into European prehistory through various journeys across the continent, publishing his findings in academic papers and books.In doing so he introduced the continental European concept of an archaeological culture to the British archaeological community.
