Plant Spirit Medicine recognizes that plants have spirit and that spirit is the strongest medicine. Spirit can heal the deepest reaches of the heart and soul. Since the beginning of time, when the traditional shaman-healer turned to the plant world, he turned to the spirits of the plants to heal his patients. The spirits were his friends, teachers, and allies. This forgotten ancient practice was reintroduced by Eliot Cowan, Teague's teacher, healer, and shaman.
