This plant is often used as remedy in herbal medicine. When the plant is in flower, the entire plant is used. An infusion of the leaves, used externally, is used as a treatment for bruising and sprains, but should not be used on broken skin, as it may lead to irritation. A cream or diluted tincture may be applied to treat alopecia.
In homeopathic medicine, Arnica Montana is used for sprains, bruises, muscle aches, physical and emotional shock and for long term consequences of trauma. A topical preparation of Arnica Montana has been shown to be as effective as the antiinfammatory ibuprofen in the treatment of osteoarthritis of the hands.
