Alternative medicine

Some common complementary and alternative treatments that have shown promise for rheumatoid arthritis include:

• Fish oil. Some preliminary studies have found that fish oil supplements may reduce rheumatoid arthritis pain and stiffness. Side effects can include nausea, belching and a fishy taste in the mouth. Fish oil can interfere with medications, so check with your doctor first.
• Plant oils. The seeds of evening primrose, borage and black currant contain a type of fatty acid that may help with rheumatoid arthritis pain and morning stiffness. Side effects may include headache, diarrhea and gas. Some plant oils can cause liver damage or interfere with medications, so check with your doctor first.
• Tai chi. This movement therapy involves gentle exercises and stretches combined with deep breathing. Many people use tai chi to relieve stress in their lives. Small studies have found that tai chi may improve mood and quality of life in people with rheumatoid arthritis. When led by a knowledgeable instructor, tai chi is safe. But don't do any moves that cause pain.
