Safflower oil can not cure synovitis, only on the synovitis pain symptoms have improved. Safflower oil is often used in rheumatism and bone pain, bruises and sprains, headaches, skin itching, etc., used for synovitis can play a role in reducing swelling and pain, but safflower oil can not cure synovitis itself. Synovitis is an inflammatory change in the synovium of the joints caused by a variety of factors (trauma, infection, tuberculosis, etc.), resulting in recurrent episodes of swelling and pain in the joints, functional limitations, muscle atrophy, etc. as the main clinical manifestations of a disease. The treatment of synovitis is aimed at relieving symptoms, preventing complications, and maintaining joint mobility. When the symptoms are mild, there is no need for treatment, but observation, rest and avoidance of exertion. When the symptoms are not significantly relieved, or aggravated, standardized treatment is required. Treatment is based on drug therapy (mainly including non-steroidal anti-inflammatory drugs such as ibuprofen orally and diclofenac ethylenediamine latex topically), physical therapy and surgery. Antibiotic treatment (e.g., cefadroxil, etc.) is also needed for acute purulent synovitis. For synovitis caused by tuberculous arthritis, rheumatoid arthritis, gouty arthritis, etc., corresponding special drug treatment is also needed. If the above treatments are not effective, surgical treatment should be considered to remove the lesion arthroscopically, including inflammatory synovium, exudates, deposits, and neoplastic organisms. The above medications should be used under the supervision of a doctor, avoiding self-medication.
