Hi,
I found this
One of the more recondite Mesoamerican inebriants is the Mayan metheglin balché, a mead of stingless-bee honey, water and bark of leguminous balché, Lonchocarpus violaceus (Jaquin) DC. (Goncalves de Lima, et al. 1977). L. violaceus is psychoactive, owing to content of longistylines (Delle Monache, et al. 1977) or piscicidal rotenone, and Mayaist C. Ratsch proposed other shamanic inebriants, like psilocybin musrooms and ololiuhqui (Turbina corymbosa (L.) Rafinesque. Xtabentún in Mayan) were once added to balché (Ratsch 1992). Ratsch thought feasible my suggestion that xtabentun may have been a balché ingredient, as honey rich in psychotropics ergoline alkaloids of this Convolvulaceæ (Hofmann 1963) - noting that the Lacandon Indians, avid balché consumers know of inebriating honeys. Contemporary shamanic use of T. corymbosa has not been documented among the Mayans, but is all but universal among indigenous groups in Oaxaca, and occurs elsewhere in Mexico (Lipp 1991; Wasson 1963). Besides psychoactivity, ergolines have potent uterotonic effects, and seeds of ololiuhqui/ Xtabentún are also used as ecbolics/oxytocics (to precipitate childbirth) by indigenous groups in Oaxaca (Browner 1985; Ortiz de Montellano and Browner 1985). 'Virgin honey' of stingless bees (Trigona sp.) is used in ethnogynecology, noting of Tabentun (Xtabentún, identified as convolvulaceous):"the aromatic honey from its flower is said to be the source of a potent drink" (Roys 1931). Oaxacan Mixe use T.Corymbosa as a shamanic inebriant, and also employ "special honey" from Trigona sp. As an ethnogynacological remedy (Lipp 1991). Clavigero highly praised estabentun honey (Clavigero 1780); entomologist H.F Schwarz attributed xtabentún honey to Melipona beecheii Bennett, noting it was still produced in Yucutan in the 1940's, being the most esteemed of many ethnomedicinal Mexican honeys (Schwarz 1948). An article on Mayan apiculture described situating hives near natural strands of xtabentún, noting "all their honey comes from this flower. No other is allowed to prosper in the immediate vicinity" (Mediz Bolio 1974). These clues suggest colecab (M.beecheii). T.corymbosa honeys were produced intentionally and much esteemed for constituent ergoline alkaloids conferring uterotonic and psychoactive properties. Such honeys may have been exploited by the Mayans in fabrication of their ritual metheglin balché, endowing the sacred inebriant with the plants legendary and chemically-verified entheogenic properties.
