Arnica is an herb that grows in Europe and the U.S. It’s often used as a skin treatment for bruises, aches, and pains.
Arnica Uses
Early studies of topical homeopathic arnica gels and ointments for arthritis symptoms of the hand and knee -- like pain and swelling -- have been positive. So far, research is mixed on whether arnica skin treatments can help ease muscle pain.

If eaten, the actual herb is toxic to the liver and can be fatal. However, some oral supplements contain highly diluted arnica. These are considered homeopathic treatments. These low-dose arnica tabletshave been studied for muscle pain, diabetic eye damage, and swelling and pain after surgery. More research needs to be done to establish effectiveness for those problems.
Because of the risks of pure arnica, the FDA classifies it as an unsafe herb. Doctors who practice complementary medicine generally advise against using arnica in any form other than in a highly diluted homeopathic form.
Arnica Dose & Instructions for Use
Arnica is usually taken by mouth, or through ointments and fresh plant gel applied on the skin.
Homeopathic treatments are usually individualized based on the specific symptoms of the patient.
For topical treatment of conditions such as osteoarthritis, it is suggested that you should use an arnica gel product and rub it into the affected joints two to three times daily for 3 weeks.
Make sure you only use diluted homeopathic preparations because pure arnica can be toxic to your liver if taken internally. While there appear to be no risks to using homeopathic arnica, it is important to consult your doctor before taking it.
Arnica Food Sources
There are no natural food sources of arnica besides the plant itself. Arnica is used as a flavoring in some food products.
Arnica Supplement Information
