From biochemistry to myth, medicine to meaning, discover the species that shaped rituals, reconfigured minds, and transformed societies.

What connects Siberian shamans, Amazonian healers, medieval monks, and Silicon Valley biohackers? Why have humans from every culture sought out plants that alter perception, mood, and consciousness? And how did simple species like betel leaf or kanna come to shape entire rituals, economies, and belief systems?

Psychoactive Plants and Fungi is a vivid and accessible introduction to 42 extraordinary species that have captivated, healed, and transformed people throughout history. From everyday stimulants like coffee and tea to rare ceremonial plants like iboga or kola nut, each profile explores the cultural origins, traditional uses, and psychoactive effects of these plants, many of which remain central to spiritual practices, social customs, and even modern wellness trends.

Richly illustrated and global in scope, the book brings together folklore, pharmacology, and anthropology to show how psychoactive species have shaped human experience, both ordinary and extraordinary. This is not a field guide or a how-to manual, but a cultural companion for the curious reader: part ethnobotanical history, part celebration of our long and complex relationship with the plant and fungi kingdoms.
