Detailed Description
-----------------
This trial is a randomized, open-label, parallel-controlled clinical trial of active drugs.With reference toDiagnosis and Treatment Protocol for COVID-19(Trial Version 9), Lianhua Qingwen Granules have been recommended for mild and common patients during the medical observation period and clinical treatment period of the new coronavirus. The purpose of the experiment is preliminary evaluate the clinical efficacy and safety of Kesuting syrup in the treatment of COVID-19 (Light) .
