Studies involving the topical use of arnica for pain relief in people with arthritis of the hands and knees have demonstrated favorable results, reports WebMD. Additionally, arnica reduces pain after surgery, states National Institutes in Health.
At least one research study has demonstrated that taking homeopathic arnica tablets and using topical gel significantly reduced pain in patients who underwent carpal-tunnel release surgery, according to NIH. Another study demonstrated that homeopathic arnica accelerated healing in rhytidectomy surgery patients by reducing bruising.
The homeopathic preparation Traumeel contains arnica and has demonstrated effectiveness in reducing pain and inflammation associated with musculoskeletal injury; however, it is the synergistic effect of the ingredients in the formula that doctors believe make it effective for pain relief comparable to the relief NSAIDS provide, explains NIH.
