There is no evidence that white vinegar and salt can treat arthritis and it is not recommended. White vinegar and salt are food, not a cure for the disease. Arthritis needs to be treated appropriately after the cause of the disease has been identified, and can be treated with physical therapy such as ultrasound therapy, rehabilitation training such as muscle exercise, medication such as ibuprofen, and surgical treatment such as orthopedic joints. White vinegar and salt does not have the efficacy of treating arthritis, and no food has the effect of treating the disease. Arthritis patients need to follow the doctor’s instructions to give standardized treatment, as follows: 1. Physical therapy: such as direct current therapy, low-frequency pulse electrotherapy, intermediate-frequency current therapy, ultrasound therapy and so on. 2. Rehabilitation training: such as muscle strength exercise, sitting elevation exercise, straight leg raising, etc. 3. Drug treatment: non-steroidal anti-inflammatory drugs, such as ibuprofen, diclofenac, etc.; chondroprotectors, such as glucosamine sulfate, etc., and intra-articular injection of sodium vitrate if necessary. 4. Surgical treatment: For the late stage of the lesion or if the symptoms cannot be relieved after the above treatments, surgical treatments can be considered, such as orthopedic joints, joint replacement, synovectomy treatment and so on. Patients with arthritis are advised to consult the doctor as early as possible and follow the doctor’s instructions to choose the appropriate treatment plan.
