The claim that the ayahuasca drink has been used for 5000 years has become formulaic. A quick search of ayahuasca tourist and related websites reveals virtually identical statements of this claim: “The use of Ayahuasca has been recorded over 5000 years ago by the natives of Amazon and surrounding areas,” And while it is true that the parenteral ingestion of DMT-containing plants is of considerable antiquity in South America, there is no corresponding archeological or documentary evidence prior to the eighteenth century for the combination of a DMT-containing plant with the ayahuasca vine for oral ingestion.
