Yes, ginger may be good for reducing CRP (C-reactive protein) levels in the body. A meta-analysis indicated that ginger supplementation led to a significant reduction in serum CRP concentrations [weighted mean difference (WMD)−0.84 mg/L (95% CI −1.38 to −0.31, I2 56.3%)].
In simpler terms, this means that studies have shown that taking ginger supplements can lower CRP levels in the blood. CRP is a marker of inflammation in the body, so reducing CRP levels can be beneficial for overall health.
