In Pharmako/Dynamis, Dale Pendell continues the exploration of psychoactive plants begun in Pharmako/Poeia. Ancient Greek herbalists used the term pharmakodynamis to refer to the intrinsic powers of plants. Pendell covers this topic and more in his new volume, as he charts a voyage around the world of plant teachers and allies. Applying poetry, chemistry, pharmacology, and a generous sprinkling of arcane lore, Pendell wends a stimulating course through the realms of plant powers, potions, and herbcraft. His is a unique adventure that arrives at last at the Ultima Thule of that "dangerous knowledge," which, in the words of Gary Snyder, is a formidable force against "even more dangerous ignorance."
