Panax notoginseng is a herbal medicine with the effect of clearing heat and detoxifying the blood and cooling the throat, which has a preventive effect on common viral infections, but there is no direct evidence that Panax notoginseng can prevent or treat novel coronavirus pneumonia. So far, no drugs have specific killing effect on novel coronavirus, although clinical trials of alpha-interferon and lopinavir/ritonavir and other antiviral drugs are underway, but none of them have exact specificity. Therefore, the new coronavirus pneumonia should be treated with symptomatic combination therapy, relying mainly on the body’s own resistance to kill and remove the virus, so the main measure to prevent viral infection is to improve the body’s resistance.
