Herbs and dietary supplements. If you decide to
use herbs or dietary supplements, be sure to tell your doctor.
Herbs such as the oil of evening primrose, borage seed, or blackcurrant seed may help relieve symptoms and improve function without significant side effects. Another herb called Tripterygium wilfordii (thunder god vine) also seems to relieve symptoms but may have side effects such as increased infection.7
Essential fatty acids (such as fish oil) may provide some
relief of symptoms.8
The dietary supplements glucosamine and chondroitin are sometimes used to
try to relieve joint pain. But there is not evidence that they are effective for rheumatoid arthritis.4
