Today public interest in the use of complementary medicine, especially traditional herbal medicines has increased. The present study was designed to investigate the efficacy of traditional preparation of Peganum harmala L oil on patients with knee osteoarthritis. The product has been analyzed and standardized by high-performance liquid chromatography. A double blind controlled randomized clinical trial consisting of 54 patients were performed.
