It is commonly applied in the treatment of conditions such as arthritis, including rheumatoid arthritis and osteoarthritis, where it helps alleviate joint pain and stiffness. Additionally, it is effective in managing acute musculoskeletal injuries, postoperative pain, and dental pain. Its anti-inflammatory properties make it suitable for addressing soft tissue injuries like sprains and strains.
