Arnica is used to:
Reduce swelling
Treat bruises (discoloration of skin due to injury)
Treat sprains (torn or stretched ligament). Ligaments connect bone to bone and hold your joints in place.
Reduce muscle pain
Treat osteoarthritis. Osteoarthritis is a disease in which the cartilage (protective tissue at the ends of bones) of your joint wears down. This can lead to pain and swelling.
Arnica also has other uses that haven’t been studied by doctors to see if they work.
Talk with your healthcare provider before taking arnica supplements. They may affect how your other medications work. For more information, read the “What else do I need to know?” section below.
