The red-black seeds, which are known by the name piule (Santesson 1938), were or are used ritually in the village of San Pedro Nexapa, on the slopes of Popocatepetl (Mexico) (Wasson and Wasson 1957, 306 f.). In Mexico, the name piule has been used as a catchall term for psychoactive plants since the twentieth century (Martinez 1987, 757*; cf. Psilocybe mexicana, Turbina corymbosa). The word piule may have been derived from the Nahuatl peyotl (= Lophophora williamsii). Accordingly, piuleros are those people who use a psychoactive substance (piule) to divine and/or heal (Santesson 1937a, 1937b). Some species, e.g., Rhynchosia longeracemosa Mart. et Gal., are now also known by the name peyote (Schultes 1966,296*). Distribution This climber is found throughout the tropical and warm regions of Mexico and on many islands of the Caribbean (Cuba) (von Reis and Lipp 1982, 139*). It usually grows at the edge of forests and in clearings. It is frequently found in fallow milpas (slash-and-burn gardens). Cultivation The seeds are best pregerminated in a mixture of soil and moss. The seedlings must be planted in topsoil and watered well as soon as the seeds have opened and the young shoots have become visible (Grubber 1991, 56*). The plant requires a moist, warm climate and in northern zones can thus be grown only as a houseplant. Appearance The vine, which can grow to a length of several meters, has the typical leaves of the Legume Family, in which three leaves sit upon each stalk. The greenish flowers are arranged in long racemes. The bean-shaped seedpods are constricted between the two small, red-black, almost spherical hard seeds (4 to 6 mm long). The kidney-shaped seeds of the closely related Rhynchosia longeracemosa are "mottled light-and dark-brown" (Schultes and Hofmann 1992,55*). Rhynchosia pyramidalis is often confused with Abrus precatorius 1. (jequirity, rosary pea), which is widely feared as a poisonous plant. It too produces red-black seeds, although they are somewhat larger (6 to 7 mm long). Jequirity can be recognized by its smaller, pinnate leaves. The seeds of Abrus precatorius contain abrin, a lectin mixture that is unstable when heated and one of the most potent of all known toxins, along with several alkaloids (Ghosal and Dutta 1971; Nwodo 1991; Nwodo and Alumanah 1991; Roth et al. 1994, 83 f. *). In Mexico, the seeds of Abrus precatorius are known as colorines (see Erythrina spp.). They are associated with the mescal bean cult (see Sophora secundiflora); ashes from the leaves are used as a coca additive (see Erythroxylum coca).

Psychoactive Material - Seeds (semina rhynchosiae phaseoloides, bird's eyes, colorines) - StalksPreparation and Dosage In entheogenic rituals in the high valleys of Mexico, twelve untreated seeds were ingested with six pairs of Psilocybe aztecorum per person (Wasson and Wasson 1957,306). Ritual Use To date, the only description that is available pertains to the ritual use of the seeds in connection with the ingestion of mushrooms. The ingestion of the seeds is presumably more symbolic in meaning, for the red-black seeds represent bodiless, free-floating eyes, a symbol of psychedelic and prophetic vision. The Zapotec of Miahuatlan are said to have used the seeds of the closely related species Rhynchosia minima (1.) DC. [syn. Dolicholus minimus] in magical rituals (Dfaz 1979,87*). Artifacts The small, durable seeds are made into amulets and chains (cf. Erythrina americana, Erythrina spp., Sophora secundiflora). Wall paintings at Teopantitla (near Teotihuacan) allegedly show the seeds falling out of the hand of the rain god TIMoc (D. McKenna 1995, 102*). The red-black coloration is said to be an indication of the seeds' hallucinogenic use (Schultes 1970c; Schultes and Hofmann 1980, 340*). Medicinal Use The seeds are regarded as a narcotic and poison in Mexican folk medicine (Jiu 1996, 254*). The Yucatec Maya use the root along with other herbs to produce a medicine to treat pellagra284 (Pullido S. and Serralta P. 1993,37*). The Pima of northern Mexico grind the seeds on a mortar and strew the powder into the eyes of those who are suffering from the "evil eye" (Pennington 1973,223*). In the Dominican Republic, the stalks are used to prepare an aphrodisiac drink (Dlaz 1979,87*). Constituents The chemistry of the constituents has not yet been clarified. Reports about the alkaloids are contradictory (Santesson 1937a). The seeds apparently contain alkaloids similar to those in Sophora secundiflora and Erythrina spp. (D. McKenna 1995, 102*). The root may possibly contain niacin or nicotine amide, for it is used in the Yucatan as a folk medicine to treat pellagra (maidism). Whether the flavonol rhynchosin (Adinarayana et al. 1980) occurs in the plant is unknown. Effects In Mexico, it is commonly believed that the seeds cause "imbecility" or "madness" (Diaz 1979, 87*; Jiu 1996, 254*). There are as yet no reports of actual psychoactive effects. An extract of the seeds is said to have curare-like activity (Schultes and Hofmann 1980,340*). Commercial Forms and Regulations The seeds are sometimes available through the international seed trade. Mexican Indians sometimes sell necklaces with beads of Rhynchosia seeds. Literature See also the entries for Erythrina spp. and Sophora secundiflora.
