Efficacy of Tart Cherry Juice to Reduce Pain and Inflammation Among Patients With Inflammatory Osteoarthritis
The purpose of this study is to assess the effects of tart cherry juice to reduce pain and inflammation among individuals with arthritis.
Numerous antioxidant and anti-inflammatory agents have been identified in tart cherries, and a study among healthy, non-exercising individuals demonstrated that cherry consumption decreased serum inflammatory biomarkers after 14 days. Osteoarthritis (OA) is a common syndrome affecting 65 million Americans characterized by pain, inflammation, and disability. Such natural anti-inflammatory effects of cherry consumption may be beneficial for the management and treatment of osteoarthritis and inflammatory diseases. The purpose of this randomized, double-blind, placebo controlled study is to examine individuals with inflammatory OA and assess the analgesic and anti-inflammatory effects of tart cherry juice as compared to a placebo drink among twenty 30-70 y/o OA subjects.
