Ayahuasca has been used for millennia by indigenous tribes throughout the Upper Amazon for healing and spiritual exploration. Shamans call the plant spirit within the vine Abuela Ayahuasca, or Grandmother Ayahuasca. Exploring the history, lore, traditional use, psychoactive effects, and current scientific studies, discover how Grandmother Ayahuasca is a profound healer, wise teacher, and life-changing guide. Examining ayahuasca from a neuroscientific perspective, the author looks at recent research on the effects of DMT—one of the psychoactive compounds in ayahuasca—as well as fMRI studies of brain activity during altered states. Offering a holistic picture of ayahuasca—from science to spirit—the author shows that this venerated hallucinogenic tea has immense therapeutic potential and just might be the long-lost shamanic connection to the sacred Gaian mind.(This book may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
