Medicinal uses: Germany alone has manufactured more than 100 drug preparations containing this herb. Applied topically as a cream, ointment, liniment, salve, or tincture, arnica has been used by both Europeans and Native Americans to soothe muscle aches, reduce inflammation and heal wounds. While arnica has also been used internally as an herbal remedy for certain heart disorders, it should only be used in this way under the supervision of a healthcare provider. In fact, arnica in herbal form is primarily restricted to topical (external) use because it can cause serious side effects when it is used internally. It is a most important stimulant and beneficial in Fibromyalgia. Arnica is especially good when breathing is only a force of the will, and becomes weak and shallow when the patient drops into sleep. When myalgia is caused by exposure, or when muscular soreness and pain are due to strain, overexertion, or sudden jars or blows, the administration of arnica internally, in small doses preferably, and the diluted tincture applied locally are among the most serviceable of measures. Arnica frequently relieves “heart-strain” due to exertion, overwork, or from long marching.
