The Chinese Materia Medica describes thousands of medicinal substances—primarily plants, but also some minerals and animal products that have antiviral, antibacterial and immunomodulating properties.
Different parts of plants, such as the leaves, roots, stems, flowers, and seeds, are used. In TCM, herbs are often combined in formulas and given as teas, capsules, liquid extracts, granules, or powders.
Some herbs are very common and may be found in your kitchen, such as ginger, garlic and cinnamon, while others such as chrysanthemum and peony flowers, are more likely to be found in your garden! Many of the substances used will be unfamiliar to you and have names like chai hu (bupleurum), di huang (rehmannia), and huang qi (astragalus).
