Medicinal use of Chrysanthemum:Chrysanthemum flowers, known in China as Ju Hua, are a bitter aromatic herb that has been used for thousands of years in Chinese medicine. The flower heads are drunk as a refreshing tisane and are used to improve vision, soothe sore eyes, relieve headaches, counter infections etc. They are antibacterial, antifungal, anti-inflammatory, carminative, depurative, diaphoretic, febrifuge, ophthalmic, refrigerant and sedative. Taken internally they dilate the coronary artery, thus increasing the flow of blood to the heart, and so are used in the treatment of hypertension, coronary heart diseases and angina. The flowers are harvested when fully open in the autumn and are dried for later use. In China they are steamed before being dried to make them less bitter. The leaf juice is smeared onto wounds.
