"Arnica is an herb that grows mainly in Siberia and central Europe, as well as temperate climates in North America. The flowers of the plant are used in medicine. Arnica is most commonly used for pain caused by osteoarthritis, sore throat, surgery, and other conditions. Arnica is also used for bleeding, bruising, swelling after surgery, and other conditions, but there is no good scientific evidence to support these uses. Arnica can also be unsafe when taken by mouth. In foods, arnica is a flavor ingredient in beverages, frozen dairy desserts, candy, baked goods, gelatins, and puddings. In manufacturing, arnica is used in hair tonics and anti-dandruff preparations. The oil is used in perfumes and cosmetics."
