Herbs – Minerals
Medicinal plants contain varying amounts of mineral substances, but they are rarely prescribed to replace minerals that have been lost from the body. Silicic acid is especially characteristic of horsetails and grasses, and some members of the Labiatae (mint) and Boraginaceae (borage) families (for example, Hemp nettles and Common Gromwell). Common Gromwell also contains abundant calcium salts, and nettles and Watercress iron. Potassium salts are found in Dandelion, Kidney Bean and Nettles, and in some fruits. Plants rich in potassium may be useful in low-sodium diets.
