From "Plants of the Gods" by Richard Evans Schultes & Albert Hoffman Common Name: Badoh Negro, Piule, Tlitlitlzen Botanical Name: Ipomoea violacea L. Usage: Oaxaca, southern Mexico. Known to Aztecs as Tlitliltzen and employed in the same way as Ololiuqui, Ipomoea is called Piule by the Chinantec and Mazatec, and Badoh Negro by the Zapotec. In southern Mexico this vine is respected as one of the principal hallucinogens for use in divination, magico-religious and curing rituals. Preparation: A drink is prepared from about a thimbleful of the crushed seeds. Effects: The alkaloid content is 5 times that of Turbina corymbosa: accordingly the natives use fewer seeds. The same alkaloids are found in other Morning Glories, but usage is restricted to Mexico (see Ololiuqui) Common Name: Ololiuqui, Badoh Botanical Name: Turbina corymbosa [synonym: Rivea corymbosa] History: The seeds of this Morning Glory, formerly known as Rivea corymbosa, are valued as one of the major sacred hallucinbogens of numerous Indian groups in southern Mexico. Their use goes back to early periods, and they were important in Aztec ceremonies as an intoxicant and as a magic potion with reputedly analgesic properties. Usage: At the present time small round seeds are utilized in divination and witchcraft by Chinantec, Mazatec, Zapotec, and others and, as has been recently stated, "today in almost all villages of Oaxaca one finds seeds still serving the natives as an ever-present help in the time of trouble." Preparation: The seeds, which must be collected by the person who is to be treated, are ground by a virgin on a metate, water is added and then the drink is filtered. The patient drinks it at night in a quiet, secluded space. Effects: Ergoline alkaloids were found to be the psychoactive principles, lysergic acid amide and lysergic acid hydroxyethylamide, closely related to the potent hallucinogen LSD, being the most important constituents.
