What Happened: A study published last month in Frontiers in Immunology titled “Quercetin and Vitamin C: An Experimental, Synergistic Therapy for the Prevention and Treatment of SARS-CoV-2 Related Disease (COVID-19)” concluded the following:
Quercetin displays a broad range of antiviral properties which can interfere at multiple steps of pathogen virulence -virus entry, virus replication, protein assembly- and that these therapeutic effects can be augmented by the co-administration of vitamin C. Furthermore, due to their lack of severe side effects and low-costs, we strongly suggest the combined administration of these two compounds for both the prophylaxis and the early treatment of respiratory tract infections, especially including COVID-19 patients.
Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, like onions, green tea, apples, berries, American elder, and many others others. Buckwheat tea also has a large amount of quercetin. The study explains:
