Objective To investigate the clinical effect of oral Chinese herbal medicine used alone in the treatment of adult viral myocarditis (AVMC). Methods CNKI, VIP, and Wanfang Data were searched for randomized controlled trials of oral Chinese herbal medicine used alone in the treatment of AVMC published from January 2000 to April 2016. The articles were screened twice and the Jadad score was determined. RevMan 5.2 was used for the meta-analysis. Results Oral Chinese herbal medicine had a significant effect in improving the clinical symptoms of AVMC (OR=3.32, 95% CI 2.42-4.57, P<0.000 01, I2=0%). It did not have significant advantages over conventional Western medicine therapy in improving abnormal electrocardiographic findings (or dynamic electrocardiographic findings) (OR=1.94, 95% CI 0.98-3.85, P=0.06, I2=71%). Conclusion Oral Chinese herbal medicine used alone may have a certain effect in the treatment of AVMC.
