Rheumatoid arthritis (RA) is a health condition that causes pain, swelling, stiffness, and loss of function in the joints. Conventional medical treatments are highly effective for RA; however, researchers are also studying complementary health approaches as possible additions to RA treatments. Some complementary health approaches for RA are intended to reduce joint inflammation, and some are intended to reduce symptoms such as pain. This fact sheet provides basic information on RA; summarizes scientific research on the effectiveness and safety of selected mind and body practices, dietary supplements, and other approaches that have been studied for RA; and suggests sources for additional information.
- In general, there is not enough scientific evidence to prove that any complementary health approaches are beneficial for RA, and there are safety concerns about some of them. Some mind and body practices and dietary supplements may help people with RA manage their symptoms and therefore may be beneficial additions to conventional RA treatments, but there is not enough evidence to draw conclusions.
- Some complementary health approaches—particularly dietary supplements—may have side effects or may interact with conventional medical treatments or each other. Although many dietary supplements (and some prescription drugs) come from natural sources, “natural” does not always mean “safe.” In particular, the herb thunder god vine (Tripterygium wilfordii) can have serious side effects.
- Conventional treatments are highly effective in slowing or stopping permanent joint damage in RA. Do not replace conventional medical therapy for RA with an unproven health product or practice.
- Tell all your health care providers about any complementary health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
About Rheumatoid Arthritis
Rheumatoid arthritis is an inflammatory autoimmune disease—a type of condition in which the immune system, which normally protects the body by fighting infections and diseases, instead targets the body. RA is different from other types of arthritis such as osteoarthritis, a wear-and-tear condition that most commonly occurs as people age. In RA, the immune system attacks the tissues that line the joints, causing pain, swelling, and stiffness in the joints and affecting their ability to work properly. Over time, RA may damage bone and cartilage within the joints and weaken muscles, ligaments, and tendons that support the joints.
RA often begins in middle age and occurs more frequently in women than in men. Although RA primarily affects the joints, particularly the wrists and fingers, some people with RA may have other health problems, such as anemia, dry eyes or mouth, and heart or lung problems. People with RA may have fatigue, occasional fevers, or a general sense of not feeling well. They may also experience other symptoms such as depression, anxiety, a feeling of helplessness, and low self-esteem.
Early treatment to avoid permanent joint damage is key for preventing disability and progression of RA. Treatment for RA combines a variety of approaches and is aimed at relieving pain, reducing joint swelling, slowing or preventing joint damage, and improving physical function and well-being. Conventional medicines used for RA include:
- Disease-modifying antirheumatic drugs (DMARDs) to slow the progress of the disease
- Biologic response modifiers to reduce inflammation and structural damage to the joints
- Nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids to reduce inflammation.
Other treatments include surgery, physical therapy, modified exercise programs, and devices that ease physical stress on the joints (such as splints). People with RA are also encouraged to make lifestyle changes such as balancing activity with rest, eating a healthy diet, and reducing emotional stress.

About Scientific Evidence on Complementary Health Approaches
Scientific evidence on complementary health approaches includes results from laboratory research as well as clinical trials (studies in people). It provides information on whether an approach is helpful and safe. Scientific journals publish study results, as well as review articles that evaluate the evidence as it accumulates; fact sheets from the National Center for Complementary and Integrative Health (NCCIH)—like this one—base information about research findings primarily on the most rigorous review articles, known as systematic reviews and meta-analyses.
What the Science Says
In general, there is not enough scientific evidence to prove that any complementary health approaches are beneficial for RA, and there are safety concerns about some of them. Some mind and body practices and dietary supplements may be beneficial additions to conventional RA treatments, but there is not enough evidence to draw conclusions. This section describes the scientific evidence on several complementary health approaches studied for RA.
Mind and Body Practices
Results from clinical trials suggest that some mind and body practices—such as relaxation, mindfulness meditation, tai chi, and yoga—help people with RA manage their symptoms and therefore may be beneficial additions to conventional treatments.
- Acupuncture has been studied for a variety of pain conditions, but very little acupuncture research has focused on RA. Reviews of the research on acupuncture have found conflicting evidence regarding its usefulness for RA.
- A 2010 systematic review looked at the benefits of mind and body techniques such as mindfulness meditation (which involves nonjudgmental attention to experiences in the present moment), biofeedback, and relaxation training on the physical and psychological symptoms associated with RA. There was some evidence that these techniques may be helpful, but overall, the research results have been mixed.
- A 2008 study compared cognitive-behavioral therapy that emphasizes pain management with mindfulness meditation for RA. The researchers found that mindfulness meditation, which helps regulate emotions, improved participants’ ability to cope with pain. The researchers noted that participants with a history of depression responded better than others to mindfulness meditation.
- A few small studies have been conducted on tai chi for RA. In general, tai chi has not been shown to be effective for joint pain, swelling, and tenderness, although improvements in mood, quality of life, and overall physical function have been reported.
- A 2010 study examined the effect of practicing tai chi on 15 patients with RA. The researchers found that tai chi improved muscle strength and endurance, but there was no evidence that it reduced disease activity or pain.
- A 2007 systematic review of the research concluded that the value of tai chi for treating RA is still unproven. Many factors—including differences in tai chi styles, number of movements, length of the practice, and qualifications of instructors—add to the challenge of designing quality tai chi studies. Some people have reported soreness, but most studies have found that tai chi is relatively safe for people with RA.
- Yoga incorporates several elements of exercise that may be beneficial for arthritis, including activities that may help improve strength and flexibility. However, only a few studies have examined yoga for RA. Preliminary studies have found that yoga may improve physical function and decrease the number of tender and swollen joints. Yoga exercises should be performed with caution by people with RA who have limited mobility or spinal problems. People with RA may need assistance in modifying some yoga postures to minimize joint stress and may need to use props to help with balance.
No dietary supplement has shown clear benefits for RA, but there is preliminary evidence for a few, particularly fish oil, gamma-linolenic acid, and the herb thunder god vine. Dosage and safety issues and potential interactions with conventional medicines need to be more thoroughly evaluated.
Fish oil contains high levels of omega-3 fatty acids—substances the body needs to perform a number of important functions. Types of fish high in omega-3s include herring, mackerel, salmon, and tuna. Fish oil supplements are available as capsules or oils.
- Clinical trials on RA have found that fish oil supplements may help to relieve tender joints and morning stiffness. Studies have also found that fish oil may reduce the need for NSAIDs and other conventional RA medicines. For example, the results of a randomized, controlled clinical trial published in 2008 found that people who received a blend of cod liver oil and fish oil over a 9-month period reduced their NSAID intake by more than one-third, compared with those who took a placebo.
- Because the omega-3 fatty acids in fish oil may make blood clot more slowly, people who take medications that affect clotting, such as anticoagulants, should discuss the use of fish oil supplements with a health care provider. Products made from fish liver oils (for example, cod liver oil) may contain vitamins A and D as well as omega-3 fatty acids; these vitamins can be toxic in large doses.
- For more information on omega-3 fatty acids, see the NCCIH Web site.
Gamma-linolenic acid (GLA) is an omega-6 fatty acid found in the oils of some plant seeds, including evening primrose (Oenothera biennis), borage (Borago officinalis), and black currant (Ribes nigrum). In the body, GLA may be converted into substances that reduce inflammation.
- There is some preliminary evidence that GLA may be beneficial for RA; however, the quality of the studies on GLA has been inconsistent. The more rigorous studies suggest that GLA may relieve symptoms such as joint pain, stiffness, and tenderness; in some cases, GLA led to a decreased need for NSAID medication.
- Side effects of GLA may include headache, soft stools, constipation, gas, and belching. Some borage oil preparations contain chemicals called pyrrolizidine alkaloids that may harm the liver.
Thunder god vine (Tripterygium wilfordii) has been used for centuries in traditional Chinese medicine. Extracts are prepared from the skinned root of the herb, as other parts of the plant are highly poisonous. Thunder god vine can cause severe side effects.
- Findings from laboratory and animal studies suggest that thunder god vine may fight inflammation and suppress the immune system. A 2011 systematic review looked at three human studies of oral (taken by mouth) thunder god vine and one study of topical (applied to the skin) thunder god vine for RA. The data showed that both oral and topical thunder god vine may improve some RA symptoms, but the study methods were not consistent among the trials.
- A systematic review of the research on thunder god vine for RA concluded that serious side effects occurred frequently enough that the risk of using it outweighs its benefits. Depending on the dose and type of extract, thunder god vine may cause serious side effects. Thunder god vine can affect the reproductive system, possibly causing menstrual changes in women and infertility in men. Long-term use may decrease bone mineral density in women, potentially increasing the risk of osteoporosis. Other side effects can include diarrhea, upset stomach, hair loss, headache, and skin rash.
Research on other supplements for RA symptoms is still in the early stages. For example:
- Varieties of boswellia (Boswellia serrata, Boswellia carterii, also known as frankincense) produce a resin that has shown anti-inflammatory and immune system effects in laboratory and animal studies, but no rigorous clinical trials in people with RA have been conducted.
- Laboratory studies have identified anti-inflammatory compounds in ginger (Zingiber officinale). Most of this research has focused on the anti-inflammatory properties of gingerol compounds—the components of ginger that give it flavor. A 2009 study funded in part by NCCIH examined whether nongingerol compounds had an antiarthritic effect in rats. The researchers found that ginger extract with both gingerol and nongingerol components prevented joint inflammation and destruction better than ginger extract containing only gingerols. They concluded that the nongingerol compounds may play a role in the antiarthritic properties of ginger. Although these laboratory and animal studies show some promise, studies regarding ginger extracts for RA symptoms in people are lacking.
- A 2010 NCCIH-funded review has found evidence that substances found in green tea might be useful for RA and osteoarthritis, but the effects of these substances in either type of arthritis have not been fully tested in people.
- In animal studies, extracts of turmeric (Curcuma longa) containing the chemical curcumin were found to protect joints from inflammation. Building on previous laboratory research that examined turmeric’s anti-arthritic properties, a 2010 study, funded in part by NCCIH, looked at whether turmeric essential oils (TEO) protected joints in rats. The researchers found that an oral dose of TEO had an anti-inflammatory effect specific to the joints. There may be a potential role for turmeric or its components in preventing or slowing RA disease, but this has not yet been demonstrated in people.
Other Types of Complementary Health Approaches Studied for Rheumatoid Arthritis
Other complementary health approaches have been studied for RA:
- An NCCIH-funded preliminary study of Ayurvedic medicine, a system of healing that originated in India and involves using individually prescribed combinations of herbs, found that classic, individualized Ayurvedic approaches, methotrexate (a conventional medication frequently used to treat RA), or a combination of both were equally effective in reducing symptoms of RA. Because this was a small, preliminary study, its results, although promising, are insufficient to show definitively that Ayurvedic medicine is helpful for RA.
- Balneotherapy is the technique of bathing in tap or mineral water for health purposes. Preliminary research on balneotherapy for RA has been conducted in areas where it is most popular, such as Europe and Israel’s Dead Sea region. Although some benefits have been reported, there is not enough reliable evidence to draw conclusions.
- Some people with RA may try following special diets—such as vegetarian and vegan diets, the Mediterranean diet, and periods of fasting—to control symptoms. Research on these diets has been inconclusive. Although a few studies suggest that decreasing or eliminating meat, dairy, or foods likely to cause allergies may help in some cases, others do not. One drawback is that special diets may be difficult for people to follow over time. In addition, some diets could put people at risk for nutritional deficiencies.
- Traditional Chinese medicine (TCM) encompasses multiple practices, including acupuncture, Chinese herbal medicine, and others. Several practices that are part of TCM, including acupuncture, tai chi, and the herb thunder god vine, have been studied individually for RA, as described above. Some research has also been done on TCM as a whole for RA symptoms and for relief of side effects from conventional RA treatments, but no conclusions can be reached because of the poor quality of some of the research, variations in study design, and insufficient data on safety.
If You Are Considering Complementary Health Approaches for Rheumatoid Arthritis
- Do not replace proven conventional treatments for RA with unproven health products and practices. Do not change your use of prescribed RA medications without consulting your health care provider. Going without effective treatment for RA could lead to permanent joint damage.
- Be aware that some complementary health approaches—particularly dietary supplements—may interact with conventional medical treatments. Also consider the possibility that what’s on the label of a dietary supplement may not be what’s in the bottle; for example, some tests of dietary supplements have found that the contents did not match the dose on the label, and some herbal supplements have been found to be contaminated. To learn more, see the NCCIH fact sheet Using Dietary Supplements Wisely.
- Women who are pregnant or nursing or people who are thinking of using a complementary health approach to treat a child should consult their (or their child’s) health care provider before using any complementary health approach.
- Tell all your health care providers about any complementary health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care. For tips about talking with your health care providers about complementary health approaches, see NCCIH’s Time to Talk campaign.
Recent NCCIH-supported research includes projects studying:
- Approaches such as yoga, fish and borage seed oils, tai chi, and relaxation for RA symptoms, physical function, and quality of life
- How celastrus, a Chinese herb, works on a cellular level and if it has the potential to treat certain autoimmune diseases such as RA.
