  Ginger Supplementation and Blood Pressure in Adults: A GRADE-Based Systematic Review and Dose-Response Meta-Analysis of Randomized Controlled Trials

  Pooling 12 randomised trials, ginger supplementation was associated with a 5.03 mmHg drop in systolic and a 2.03 mmHg drop in diastolic blood pressure, with larger reductions in trials that used 2000 mg a day or more. The authors rate the certainty of their own evidence as low, because the trials disagree with each other.
