Pain in the joints has been a common and serious health issue for a long time. In Unani medicine, both inflammatory and non-inflammatory joint problems are grouped under the term "Waja‘al-Mafāṣil," which means joint pain. Osteoarthritis, based on its symptoms, is very similar to a condition in Unani medicine called Waja‘al-Mafāṣil Balghamī. One of the most common types of osteoarthritis is Knee Osteoarthritis (KOA), which is known in Unani medicine as Waja‘al Rukba. This chronic and painful condition is usually treated with non-steroidal anti-inflammatory drugs (NSAIDs), but these drugs can have many side effects. In contrast, the Unani system of medicine uses a more comprehensive approach to manage osteoarthritis. Waja‘al Rukba is managed with Istefragh (evacuation) followed by Tadeel Mizaj (rejuvenation), Taqwiyat (strengthened) and Taskeen (pain is relieved). Istefragh is achieved using specific Unani herbal treatments, like Munzij-Mushil Therapy followed by Tadeel Mizaj using various techniques, including Ḥijāma (cupping), Dalk (massage), Ta‘līq al-‘Alaq (leech therapy), Ḥammām (Turkish Bath), Takmeed (fomentation), Naṭūl (irrigation), Qay‘ (vomiting), and Ḥuqna (enema). Taskeen and Taqwiyat are achieved using either medications or these modalities. This overview focuses on Waja‘al Rukba and its Regimenal management.
