In vivo anti–SARS-CoV-2 assay conducted in female golden Syrian hamsters. (A) Virus elimination effect of drugs and extracts. Hamsters were infected with SAR-CoV-2 by intranasal instillation at day 0, and treated with drugs and extracts orally twice a day (30 mg/kg/d for drugs and 200 mg/kg/d for extracts) continuously for 3 d. After 3 d, the lungs were collected to measure the virus load (n = 5), *P < 0.05; **P < 0.005. (B) Body-weight change after 3-d treatment, n = 5 for test group and n = 6 for the control group.
