Coronavirus disease 2019 (COVID-19) is an ongoing public health concern globally. This study aims to collect evidence for Chinese medicine (CM) against COVID-19 by reviewing clinical trials. We searched eleven databases. An initial search of 4,180 studies was found and the final number of included studies remained at 52. The RoB 2.0, ROBINS-I and GRADE tools were used to assess the risk of bias and level of evidence. The findings with moderate certainty in GRADE showed that compared with routine treatment (RT), Lianhua Qingwen granules (LHQW), Qingfei Paidu decoction (QFPD), Feiyan Yihao formula (FYYH), and Jinhua Qinggan granules (JHQG) have adjunctive effects on COVID-19 symptoms, including clinical efficacy rate, febrile score/time, duration of hospital stay and negative conversion time of the nucleic acid test. No serious adverse events were observed. The current evidence supported that CM formulations, particularly LHQW, QFPD, FYYH, and JHQG, have an adjuvant effect on standard treatment of COVID-19 [1].
