Objective: A meta-analysis was performed to determine effect of ginseng on blood pressure. Methods: The databases of PubMed, Embase, Cochrane Library, RISS, DBpia, KISS, and Koreamed were searched for all published studies from inception to January 2016. The following terms were used: “ginseng”, “hypertension”, and “blood pressure”. Using the Review Manager 5, mean differences (MDs) were pooled to measure the effect of ginseng on blood pressure compared to that of placebo. Results: Eleven randomized controlled trials were included. In this meta-analysis, ginseng treatment significantly lowered systolic blood pressure (SBP) in a dose-independent way (MD: −1.99, p = 0.04). In subgroup analysis, 8-12 week consumption of ginseng achieved significantly greater reduction in SBP (MD: −3.14, p = 0.03), while single administration of ginseng failed to show BP-lowering effect. When ingested over 8-12 weeks, ginseng significantly lowered diastolic blood pressure (DBP) (MD: −1.96, p = 0.03). No significant association was found between ginseng dose and the magnitude of BP- lowering effect. However, a significant positive relationship was observed between baseline SBP level and the magnitude of SBP reduction (r = 0.848, p = 0.033). Such a relationship was not seen in DBP. Conclusion: Consumption of ginseng for 8-12 weeks achieved significant reductions in SBP and DBP in a dose-independent way. There was a significant positive relationship between baseline SBP level and the magnitude of SBP reduction.
