A chemical element found naturally in foods like garlic and onions, sulfur shows promise in the treatment of arthritis. For instance, studies indicate that taking supplements that contain methylsulfonylmethane (or MSM, a form of sulfur) may offer relief of osteoarthritis of the knee. Found to fight inflammation, MSM may help lessen osteoarthritis-related pain . There\'s also some evidence that soaking in sulfur-rich waters may benefit people with osteoarthritis. In a 2007 study from the Cochrane Database of Systematic Reviews, investigators determined that balneotherapy (a therapeutic form of bathing that often involves sulfur-rich waters) may tame pain and improve quality of life in osteoarthritis patients. For more help in treating arthritis, consider taking supplements that contain avocado/soybean unsaponifiables or glucosamine. In addition, practicing yoga, taking up tai chi, and/or undergoing acupuncture may help alleviate arthritis pain and enhance functioning.
