Beginning with the botany and cultivation of the ergot fungus, Albert Hofmann guides readers through its complex history, from devastating ergot poisoning epidemics in medieval Europe to its early applications in medicine.
From there, the book traces the evolution of pharmaceutical and chemical research between 1816 and 1961, including the groundbreaking synthesis of ergotamine and the emergence of lysergic compounds such as lysergic acid and LSD. Hofmann situates these discoveries within the rise of experimental psychiatry, where such substances began to be explored as tools for psychotherapy and the study of consciousness.
What sets this work apart is its bridge between science and tradition. Alongside detailed chemical structures and laboratory insights, Hofmann honors the longstanding ceremonial and healing use of psychoactive plants and fungi by Indigenous cultures. He reflects on sacred medicines such as the peyote cactus, teonanácatl (the Aztec “sacred mushroom”), and ololiuqui (morning glory seeds), offering a rare perspective that integrates scientific inquiry with ancestral knowledge.
