ABSTRACT=<p><bold>Background:</bold><italic>Helicobacter pylori</italic> (<italic>H. pylori</italic>) infection is one of the most common chronic bacterial infections worldwide. The resistance of <italic>H. pylori</italic> to antibiotics may increase the risk of treatment failure. Complementary and alternative regimens are still needed. This study aimed to critically assess the efficacy and safety of Jinghua Weikang capsule (JWC) for <italic>H. pylori</italic> eradication.</p><p><bold>Materials and methods:</bold> PubMed, Embase, Web of Science, Cochrane library, China National Knowledge Infrastructure, Wanfang Digital Periodicals, and Chinese Science and Technology Periodicals database were searched from inception to April 2022. Randomized controlled trials (RCTs) comparing a combination of JWC and conventional treatments with conventional treatments alone or combined with a placebo for <italic>H. pylori</italic> eradication were considered for inclusion. The primary outcome was <italic>H. pylori</italic> eradication rate. The meta-analysis and trial sequential analysis (TSA) were conducted where possible.</p><p><bold>Results:</bold> A total of 34 studies were included in the statistical analysis. A pooled result showed that JWC with the duration of 2 weeks combined with the triple/quadruple therapy could significantly increase the <italic>H. pylori</italic> eradication rate compared with the triple/quadruple therapy alone (RR: 1.13, 95% CI: 1.05 to 1.21, <italic>p</italic> = 0.0008). However, the evidence of benefit was not confirmed by TSA. Another pooled result showed that JWC with the duration of 4 weeks combined with the triple/quadruple therapy could significantly increase the <italic>H. pylori</italic> eradication rate compared with the triple/quadruple therapy alone (RR: 1.21, 95% CI: 1.15 to 1.27, <italic>p</italic> &lt; 0.00001). The evidence of benefit was confirmed by TSA. There were no statistically significant differences in the incidence of adverse reactions between the two groups.</p><p><bold>Conclusion:</bold> The present study suggests that JWC with the duration of 4 weeks can significantly improve the <italic>H. pylori</italic> eradication rate and should be considered as a complementary treatment to conventional regimens for <italic>H. pylori</italic> eradication. However, more high-quality RCTs are still needed to confirm these findings.</p>
