Abstract
Knee Osteoarthritis (OA) is a progressive degenerative joint disease affecting the quality of life of the elderly population. There is considerable evidence that nutraceuticals from natural herbs may play a significant role in inflammation and joint destruction in OA. We review the current status of some of the commonly used nutraceuticals in Indian market - Boswellia, Aflapin, Chondroitin sulphate, Glucosamine sulphate, Collagen peptide, Curcumin, Fish Oil, Ginger, Green tea, and Rosehip extract. We have summarized their mechanism of action, biological effects, toxicities and efficacy in the management of Knee OA. These supplements have been found to be effective in knee OA in various studies. No serious side effects have been reported for any of these supplements. Overall, our study identifies and support the use of these nutraceuticals to provide symptomatic relief to patients with knee OA and justify their use as an adjunct therapy for the management. More good quality trials are needed to provide definitive answers to questions related to their efficacy and safety for OA prevention and treatment.
