Chinese researchers use computers to analyze compounds in the herbs of “traditional Chinese medicines” and report that Quercetin appears to be the best potential inhibitor of Covid-19 initial infection.
Quercetin showed a higher binding affinity to both ACE2 and the RBD of the spike protein. The dual binding effect of quercetin could therefore be synergistic and provide a strong antiviral effect against SARS-CoV-2. Furthermore, since analysis suggested that quercetin could affect immunomodulation, and because studies have shown patients with severe COVID-19 disease tend to experience cytokine storms, quercetin could help alleviate symptoms in such cases.

Canada was supposed to do a joint clinical trial with China of 4 grams per day of pure Quercetin as a Covid-19 Treatment but somehow the trial never got started. Canadian research in animals showed that Quercetin is a treatment for several viruses, including the highly deadly Ebola virus.
