BackgroundDyslipidaemia is a major risk factor for coronary heart disease (CHD). Danhong and Huangqi injections, two traditional Chinese medicine prescriptions, have been widely studied regarding their lipid-lowering properties. However, the results were inconsistent and inconclusive. Thus, we conducted this meta-analysis of clinical controlled trials to clarify the lipid-lowering effects of Danhong and Huangqi injections.MethodsThe databases including PubMed, Google Scholar, Web of Science, Cochrane Library, Wanfang Database, CNKI and VIP were searched. The following information was obtained from each study: first author, age, gender, ethnicity, health condition, treatment dose, treatment duration, sample size, mean and standard deviation or standard error of lipid variables before and after treatment. The changes in lipid levels from pre- to post-treatment were calculated and compared between the control groups and the treatment groups in this meta-analysis.ResultsForty-four studies (5021 subjects) and 7 studies (542 subjects) were respectively identified for Danhong and Huangqi injections. Compared with the control groups, Danhong injection yielded a significant reduction in triglycerides (TG) [standardized mean difference (SMD) = - 0.76, 95% confidence interval (CI) = (- 0.91, - 0.61), P <  0.001], total cholesterol (TC) [SMD = - 1.29, 95% CI = (- 1.56, - 1.03), P <  0.001] and low-density lipoprotein cholesterol (LDL-C) [SMD = - 0.76, 95% CI = (- 0.93, - 0.59), P <  0.001], and a significant elevation in high-density lipoprotein cholesterol (HDL-C) [SMD = 0.70, 95% CI = (0.41, 0.98), P <  0.001]. Regarding Huangqi injection, it yielded a significant reduction in TC [SMD = - 1.13, 95% CI = (- 2.09, - 0.16), P = 0.02] and marginally in TG [SMD = - 1.27, 95% CI = (- 2.53, 0.00), P = 0.05] comparing with the control groups.ConclusionsDanhong injection can effectively decrease the plasma levels of TG, TC and LDL-C, and increase HDL-C levels. Huangqi injection also has significant effects on TG and TC reduction, but not as powerful as Danhong injection.
