The author creates a vast sweep of herbalism, drawing from western botanical knowledge; homeopathy; TCM, and native american shamanic botany. Detailing the history and use of more than 40 plants, he shows how each tradition views a plant, as well as its use in cases from his own herbal and homeopathic practice. An initial section describes signatures, similars, and patterns in these traditions, plus elements, temperaments, and constitutions.
