Summary

This study tests whether a cream made with L-menthol and balsam copaiba oil can reduce symptoms of arthritis, joint pain, and muscle pain. Adults aged 20 to 65 with mild-to-moderate joint discomfort apply the cream or a placebo to affected areas three times daily for seven days. Researchers measure changes in pain, stiffness, and quality of life through questionnaires.
