Ceremonies of drinking the psychoactive brew ayahuasca have flourished across the planet in recent decades. Emerging from Indigenous roots in the Amazon rainforest, the brew is now envisaged by many as the spiritual gateway to archaic and primordial worlds, with reports of healing, spiritual insight, and awe-inspiring visions placing ayahuasca among the burgeoning field of psychedelic medicines. Astonished and allured by descriptions of ayahuasca experiences, researchers in psychology, anthropology, and philosophy have attempted to define the shared properties of the visions. In this book, Alex Gearin challenges this simplified obsession with universal or primordial truth and explores the situated and embodied practices of contemporary ayahuasca drinkers to reveal how the brew has conjured contradictory experiences across the globe. These range from urban disenchantment and capitalist mastery to competitive sorcery and ecological harmony, wherein the plant-induced visions embody different attitudes towards capitalist modernity. Based upon ethnographic research among Shipibo healers in remote Peru, alternative medicine groups in urban Australia, and entrepreneurs and corporate managers in mainland China, Global Ayahuasca examines how the wondrous visions of ayahuasca are entangled within the social and economic realities that they illuminate, revealing tensions, fears, and hopes of everyday modern life.
