RESUMO

Most Orinocoan ethnic groups, including the Cuiva and the Piaroa, use yopo, a hallucinogenic snuff derived from the seeds of the Anadenanthera peregrina tree. This study contrasts Piaroa and Cuiva attitudes toward and uses of yopo in light of ongoing processes of social change. We do not believe that these sociocultural forces will lead to a phasing out of yopo in Piaroa and Cuiva life. However, we demonstrate how, in nearby communities, a combination of historical and ethical contingencies lead to very different patterns and understanding of drug use. Yopo is strongly associated with the performance of narratives central to each ethnic group's cosmology and identity. Cuiva yopo consumption is also a means of resisting persecution and asserting the right to a just reality. Piaroa attitudes towards yopo are affected by the interplay of shamanic ethical principles and missionary activity, and are sometimes paradoxical: yopo is the reason for harm and the means of salvation; required by shamans to create the future and yet regarded by many laypeople as a relic of the past. We identify persecution, local responses to missionary activity, and shamanic ethics as key factors affecting the evolution of hallucinogen use by Amazonian ethnic groups.

RESUMO

Recent attention to the monoamine oxidase inhibiting properties of Banisteriopsis caapi's harmala alkaloids has precluded a balanced assessment of B. caapi's overall significance to indigenous South American societies. Relatively little attention has been paid to the cultural contexts, local meanings and patterns of use of B. caapi among snuff-using societies, such as the Piaroa, who do not prepare decoctions containing N,N-dimethyltryptamine (DMT) admixtures. This article reviews the psychopharmacological literature on B. caapi in light of recent ethnographic work conducted among the Piaroa of southern Venezuela. Piaroa shamans use only B. caapi's cambium, identify at least five distinct varieties of B. caapi, and emphasise the plant's importance for heightening empathy. Some Piaroa people also attribute a range of extra-shamanic uses to B. caapi, including as a stimulant and hunting aid. In light of the psychopharmacological complexity of harmala alkaloids, and ethnographic evidence for a wide range of B. caapi uses,future research should reconsider B. caapi's cultural heritage and psychopharmacological potential as a stimulant and antidepressant-like substance.

RESUMO

Current understanding of the preparation and use of yopo, a hallucinogenic snuff made from the ground seeds of the Anadenanthera peregrina tree, has departed little from the accounts of scientists and travelers made over a century ago. Schultes and others have made refinements to these early accounts. While several scholars have drawn attention to the fact that little ethnographic work has been conducted to assess the ethnobotanical diversity and cultural framework of the snuff hallucinogen complex, few subsequent studies deal with botanical variations in preparation and use. This article contrasts historical accounts of yopo preparation with ethnographic data I have recently collected among the Piaroa of southern Venezuela to demonstrate one way in which yopo preparation and use deviates from the basic model established by Humboldt, Spruce and Safford. Piaroa shamans include B. caapi cuttings in the preparation of yopo and consume doses of B. caapi prior to snuff inhalation concomitant with the strength of visions desired for particular tasks. I argue that the combined use of yopo and B. caapi by Piaroa shamans is pharmacologically and ethnobotanically significant, and substantiates claims of the use of admixtures in snuff; further ethnographic investigation of the snuff hallucinogen complex is necessary.
