"This is no simple compendium of herbal recipes and cures, but a book that digs deeply, exploring the roots of humanity’s spiritual and physical illness and the amazing power of plants to heal. Evolutionary Herbalism masterfully blends the metaphors of science, metaphysics, medical astrology, and alchemy into a deeply insightful journey that takes us to the very heart and soul of herbalism and provides a holistic model for understanding people and plants." (Rosemary Gladstar, author of Rosemary Gladstar's Medicinal Herbs: A Beginner's Guide)

"Well researched at the scholarly level, Evolutionary Herbalism includes the author's own profound experiential knowledge of the subject. Pushing the boundary of modern herbal medicine, this book provides us with a new vision of the herbal realm teeming with life and intelligence that will work with us as a partner and powerful ally once we understand how to initiate that contact. Sajah Popham provides us with a wealth of hard-won tips and guidance to open that wider vista of the herbal realm." (Robert Allen Bartlett, author of Real Alchemy: A Primer of Practical Alchemy) 

"Sajah Popham has written an intelligent and genuine book in which his deep caring for the world and the suffering of people shines through. Evolutionary Herbalism is a wide-ranging, synergistic exploration of multiple systems of traditional herbal healing." (Stephen Harrod Buhner, author of Plant Intelligence and the Imaginal Realm)
