Curcumin may relieve knee osteoarthritis (OA) pain

People with osteoarthritis (OA) often take non-steroidal anti-inflammatory prescription drugs (NSAIDs) for pain, which have harsh side effects.

In this study, 139 people with OA of the knee took 500 mg of curcumin three times per day, or a 50 mg dose of the NSAID diclofenac twice per day. After 14 and 28 days, both groups reported similar reductions in joint pain and stiffness, and improvements in daily living functions.

The curcumin group reported much less flatulence, and none in the curcumin group needed drugs to combat heartburn compared to 28 percent for NSAIDs.

Overall, 13 percent in the curcumin group reported unwanted side effects compared to 38 percent for NSAIDs. Also, after 28 days, the curcumin group reported a slight weight loss.
