Mountain Tobacco (Arnica Montana) - Also called Leopard's Bane, Wolf's Bane, Mountain Tobacco, and Mountain Arnica. Arnica montana is sometimes grown in herb gardens and has long been used medicinally. This daisy-like mountain flower can be used for: bruises, sprains, soreness and swelling/muscle spasms from sports activity; arthritis set off by seasonal change; general muscle and joint pain. Some people are sensitive to the compound helenalin found in arnica. If you develop a mild rash, then you are probably helenalin-sensitive and should stop using arnica.
As an herb, arnica is usually used topically (on the skin) because it can cause serious side effects when taken by mouth. Oral homeopathic remedies do contain arnica, but they use a diluted form that is not considered dangerous. If you have any question about whether you have the herbal or homeopathic form of arnica, talk to your doctor.
