Clinical Trial Summary

COVID-19 virus remains in infected patients for extended periods of time. A great resource burden is placed on the healthcare system and society at large to isolate COVID-19 patients for prolonged periods. Thus, being able to increase the rate of viral clearance, thus reducing the duration of COVID-19 infection, would allow patients to be discharged earlier to free up resources for those who require it. The investigators designed a randomized controlled trial, investigating the use of Lianhua Qingwen, a TCM treatment, in COVID-19 infected patients with mild symptoms. The investigators hypothesize that the use of Lianhua Qingwen will increase the proportion of patients who test negative for COVID-19 after 8 days of TCM treatment when compared to the group of patients provided with standard care and placebo. Patients will be recruited from community isolation facilities, and have onset of symptoms within 5 days prior to admission to the isolation facility. The trial also evaluates the time taken for relief of clinical symptoms associated with COVID-19 and assesses the safety of the TCM treatment given to patients.
