There is no strong evidence from clinical trials to prove the definitive efficacy of biflorin against novel coronaviruses. The preparation of biflorin contains metabolites of various plants, such as phenylethanol glycosides and lignans. It has certain broad-spectrum antiviral, antibacterial, and immune function improvement effects, but it is not specific to coronavirus, and it is recommended not to use the drug arbitrarily. To fight the new coronavirus, the main precautions are to go out less, wear a mask and wash hands more often. In case of fever and cough, it is recommended to visit a nearby fever clinic as soon as possible.
