Antiviral Oral Liquid is a relatively old proprietary Chinese medicine, which works mainly to clear heat, detoxify, cool blood and benefit dampness. Whether it can treat novel coronavirus infection mainly depends on whether the patient with novel coronavirus infection has wind-heat on the surface and damp-heat and blood stasis. If the patient has symptoms of wind-heat on the surface, such as fever, headache, heartache, sore throat, red tongue, dry mouth, thirst or yellowish greasy moss, which is consistent with the pattern of the disease, then the oral antiviral solution can be used. Chinese medicine treatment is to look at the pulse evidence, know what is wrong, and treat it according to the evidence. If the patient has any abnormality, Chinese medicine should be used to correct the abnormality, so that the abnormality can be normalized. It is not the same as the Western medicine treatment of finding the culprit and killing the virus. Therefore, there are many cases of different treatment for the same disease or different treatment for the same disease in Chinese medicine. The treatment method mainly depends on the type of evidence, to see whether the patient’s current state is in line with the therapeutic range of proprietary Chinese medicines, if so, proprietary Chinese medicines can be used appropriately.
