The “plant turn” in anthropology, while controversial, has led to a renewed focus on how humans relate to different species of plants. In this article, I aim to contribute to our knowledge of human-plant relationships by analyzing how historical actors used sacred plants in past ritual settings. I study criminal and civil cases involving shamans in late colonial Ecuador, with a focus on plant use. Legal records from 1782, 1793, 1800, and 1802 reveal information about the use of fragrant plants (...) believed to have transformative properties, the use of entheogens for non-visionary purposes, and even the incorporation of the sacred wanduc (Brugmansia sp) into the punishment of one shaman. This plant-focused approach to the reading of ethnohistorical documents provides a history of particular plants as they were used by individual actors in specific geographic and historical contexts, and sheds light on people’s understanding of human-plant-spirit relationships.

Here, we describe how Casas Grandes Medio period (AD 1200 to 1450) shamanic practices of the North American Southwest used tobacco shamanism, a ritual stance called the Tennessee Diviner (TD) posture, and cultural expectations to generate trance experiences of soul flight and divination. We introduce a conceptual model that holds that specific trance experiences are the emergent result of human minds interacting with additional factors including entheogens, cultural expectations, physiological states, postures/movement, and sound/stimulation. Experimental and ethnographic evidence indicates initiating trance (...) with either tobacco intoxication or the TD posture accompanied with a rapidly beating drum or rattle corresponds with perceptions of soul flight, transformation, and divination/information acquisition. Both have similar results but pairing them together as they were during the Medio period likely helped ensure the culturally desired trance experiences. This practice of mutually reinforcing factors was likely part of tobacco‐based shamanism found in other New World cultures as well. We suggest our general model can be applied to other contexts to examine how various aspects of trance induction interact to produce the cultural patterns (and resulting cosmological and spiritual frameworks) anthropologists have documented in other cultures.

As anthropology becomes more interested in consciousness and its numerous states, and with a slowly increasing appeal to neuroscience for insights and explanations of consciousness, there is an understandable interest in the components of consciousness and how they combine into alternative states in different sociocultural settings. One of those components should be the complexity of information processing producing the knowing aspect of consciousness. The author introduces an approach to this aspect in the form of conceptual systems theory, a neo-Piagetian model (...) of cognitive development, which has been used to good effect to explain information processing in social situations but heretofore neglected by anthropologists. The neuroanthropological underpinnings of CST are discussed, as is the range of potential applications to ethnological and ethnographic problems. (shrink)
