Objective: The purpose of this study is to investigate the effect of Cheonmagudeung-eum (CGE) for essential hypertension by systematic review and meta-analysis. Methods: The period of literature search was until October 30, 2016, and 14 electronic databases were utilized as search engines. The evaluation for the risk of bias (RoB) was conducted by using the Cochrane Risk of Bias Tool. The meta-analysis was performed by synthesizing outcome data, including total effective rate (TER), systolic blood pressure (SBP), diastolic blood pressure (DBP), and the incidence of adverse events. Result: There were a total of 64 RCTs using CGE on adult essential hypertension. In the RoB evaluation, most of the items were unclear, and the qualities of studies were rated low. The concurrent treatment of CGE and antihypertensive drug (AHD) showed a significant hypotensive effect since the risk ratio (RR) of TER was 1.17 times (95% CI 1.14, 1.20, p<0.01) higher than that of AHD alone. In addition, the mean difference (MD) appeared low as 8.73 mm/Hg in SBP (95% CI -11.36, -6.09, p<0.01) and 5.81 mm/Hg in DBP (95% CI -7.50, -4.12, p<0.01). Conclusion: Through this study, it was identified that the combined treatment of CGE and AHD on hypertension would be more effective than that of AHD treatment alone. However, due to the low quality of the selected original articles, the significance of this conclusion is somewhat limited, and we hope that this would be complemented through more rigorous RCTs in the future.
