Arnica, short for Arnica montana, is a perennial plant found in the mountainous areas of Europe and North America that produces yellow-orange daisy-like flowers. Since the 1500s, the fresh or dried flowers of the arnica plant have been used for medicinal purposes. Arnica is used for bruises, sprains, muscle soreness, and muscle spasms often associated with sports activity. Arnica is also used to treat muscular aches, joint pain, and arthritis. It is believed that the arnica plant has anti-inflammatory properties. Arnica has also been used for wound healing, superficial phlebitis, inflammation caused by insect bites, and swelling caused by broken bones.
