Wood describes a universal "language of the shamans," based on direct, sometimes supernatural experiences as well as case studies from his practice. He examines the alphabet of Nature and spiritual lessons personified in animals and plants, especially "animal medicines"--when the plant looks like an animal. He shares accounts of Turtle Medicine plants for self-examination, Bear Medicine plants to open the imagination, and Wolf Medicine plants for wholeness and magic. He explores the plants of Alligator Medicine for healthful prosperity, Horse Medicine plants to bring the conscious self in harmony with the animal self, Badger Medicine plants to strengthen gut instincts, and many other herb and animal teachers. He also looks at plants associated with journeying to the spirit world through the medicine of Crane, Dragon, and Bat.
