The herb boswellia serrata reduced pain and stiffness of the knee and improved the ability to perform daily tasks in those with osteoarthritis (OA) of the knee, according to a new study. Researchers from the Government Medical College, Nagpur, India, compared the effects of boswellia serrata and the prescription medication valdecoxib (Bextra ®
) in 66 people aged 40 to 70 with OA of the knee over a six-month period.
Doctors gave 333 mg of boswellia serrata extract (BSE) three times per day or 10 mg of Bextra once per day for six months and found that those who took Bextra improved in all measures within one month, but symptoms returned as soon as the drug treatment stopped. The BSE group took two months to improve, but the improvement lasted for one month after stopping treatment.
