   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.

"Another Morning Glory, Ipomoea violacea, was valued as a sacred hallucinogen
among the Aztecs who called the seeds Tlitliltzin, from the Nahuatl term for
"black" with a reverential suffix. The seeds of this Morning Glory are
elongate, angular, and black, whereas those of Turbina corymbosa are round
and brown."
 
"Ipomoea violacea is used especially in the Zapotec and Chatin area of
Oaxaca where it is known as Badoh Negro, or in Zapotec, Badungas. In some
Zapotec villages both Turbina corymbosa and Ipomoea violacea are known; in
others, only the latter are used.  The black seeds are often referred called
macho ("male") and men take them; the brown seeds, called hembra ("female")
are ingested by women. The black seeds are more potent than the brown,
according to the natives, an assertion borne out by chemical studies. The
dose is frequently seven or a multiple of seven; at other times, the familiar
13 is the dose.  As with Turbina, Badoh Negro seeds are ground and placed in
a gourd with water. The solid particles are strained out, and the liquid is
drunk. Revelations of the cause of illness or divinations are provided during
the intoxication by "intermediaries" - the fantastical badu-win or two little
girls in white who appear during the seance. A recent report of the seeds of
Ipomoea violacea among the Zapotec, indicates that Badoh Negro is indeed a
significant element in the life of these Indians: '...Divination about
recovery in sickness is also practiced by means of a plant which is described
as narcotic. This plant ... grows in the yard ... of a family who sells it's
leaves and seeds ... to administer to patients ... the patient, who must be
alone with the curer if not in a solitary place where he cannot hear even a
cock's crow, falls into a sleep during which the little ones, male and
female, the plant children [bador], come and talk. The plant spirits will
also give information about lost objects.' "
 
"The modern ritual with the Morning Glory seeds now has incorporated Christian
elements. Some of the names- Semilla de la Virgen ("seed of the Virgin", and
Hierba Maria ("Mary's herb") - show union of the Christian with the pagan,
and clearly indication that Turbina corymbosa and Ipomoea violacea are
considered gifts from the gods."

                               CAPTION:
"The shaman administers the infusion to a patient assisted by a young girl.
The brew must be taken at night in a secluded and quiet place. The patient's
problems will be diagnosed by the shaman from interpretation of what he says
during the course of the intoxication."
