Arnica has been used for centuries as a natural pain reliever. Modern uses of arnica include the treatment of muscle pain, joint pain, inflammation, and bruising. There are at least 150 different bioactive components in Arnica, with demonstrated anti-inflammatory, antioxidant, anti-microbial, and other biological activities. In 2021, a review of studies on herbal therapies for osteoarthritis concluded that arnica gel is about as effective as topical NSAIDs for inflammation and pain relief.
