Effects of supplementation with green tea catechins on plasma C-reactive protein concentrations: A systematic review and meta-analysis of randomized controlled trials.

Promising experimental and clinical trials suggest that green tea decreases the inflammatory process in cardiometabolic diseases, but evidence from epidemiologic studies about the effects on plasma C-reactive protein (CRP) seems inconsistent and ambiguous. Therefore, the aim of this meta-analysis was to evaluate the effects of green tea supplementation on plasma CRP concentrations.
