While some of the subjects are pioneers in their own right, the authors in this collection go beyond merely adding women to the past in psychedelic history, exploring some of the significant ways that women have contributed to psychedelic knowledge. Blending historical and anthropological approaches with a series of captivating interviews, this collection taps into women’s networks around the world throughout the 20th century. It reveals some of the sophisticated and creative ways women have influenced our understanding of psychedelics and how they will continue to protect these stories as we face our psychedelic future. Our collection intentionally moves beyond an American set of stories, teasing out networks in Latin America. This collection brings together authors from the Chacruna Institute and Chacruna Latinamérica to engage readers in conversations that move across time and place throughout the Americas. It is the first of its kind to balance non-English contributions through translation of stories exploring different cultural contexts outside the United States, where women have contributed to this enduring history.
