Chinese Herbal Medicine uses herbs and other natural substances to heal based on the fundamental principles of Chinese Medicine. Herbal formulas are prepared through a combination of plants (primarily), but also some mineral and animal products that work synergistically to produce a harmonizing therapeutic treatment. Different parts of plants, such as the leaves, roots, stems, flowers, and seeds are used, each containing unique therapeutic qualities. Herbal preparations come in forms of teas, capsules, tea pill, liquid extracts, granules, or powders.
