This study aims to examine the efficacy and safety of for the treatment of Chinese herbal medicine formula combined calcium antagonist hypertension. Methods: PubMed, the Cochrane library, CNKI, VIP, Sinomed, and Wanfang Database were searched up to January 31, 2021. Data analysis was performed using the Recman 5.3. The source of clinical heterogeneity used stata16.0 for sensitivity analysis. Results: 17 RCTs and 1587 cases were finally included. The results shows that the traditional Chinese medicine decoction combined with calcium antagonists is better than calcium antagonists alone in the treatment of hypertension. In addition, it can effectively alleviate the adverse reactions caused by calcium antagonists. However, due to the low quality of methodology and the small-scale research, more high-quality clinical trials are still needed for verification.
