While looking for complementary methods to treat your arthritis, you learned about a spice called turmeric. Could it really work to relieve your joint pain?

While more research is necessary, the health benefits of turmeric — including for osteoarthritis — do look promising.

Turmeric, a plant related to ginger, is a major ingredient in curry powders and is used as a coloring for foods, fabrics and cosmetics. The stems of the plant are dried and made into capsules, tablets, extracts, powders or teas. Or it may be made into a paste to apply to the skin.

Turmeric's main active ingredient — curcumin — is what gives the spice its yellow color. Curcumin is reported to have anti-inflammatory properties, making it a potential treatment for a number of health conditions.

What the research says

When it comes to osteoarthritis, research suggests that curcumin may reduce pain and increase ease of movement. One study found that taking turmeric extract three times a day was comparable to taking 1,200 milligrams of daily ibuprofen. But more research is necessary.

Other research suggests that curcumin may lessen some of the symptoms of rheumatoid arthritis, like joint swelling and morning stiffness. It may also be effective in reducing cholesterol and triglyceride levels.

Other areas of research include curcumin's effect on Alzheimer's disease, Crohn's disease, certain cancers, depression, diabetes, joint pain and irritable bowel syndrome.

What to know before taking turmeric

When taken by mouth or applied to the skin, and limited to about 8 grams a day, turmeric appears to be generally safe. High doses or long-term use may cause gastrointestinal upset for some people.

It's wise to talk to your doctor before starting any supplement. It's especially important to ask your doctor about taking turmeric if you have gallbladder disease, since it may worsen this condition. Also talk to your doctor if you take an anticoagulant medication like warfarin, since turmeric may increase the risk of bleeding.

Also note that some turmeric products contain pepper extract. Mayo Clinic experts advise looking for turmeric products without this extract.
