Quercetin and its Relative Therapeutic Potential Against COVID-19: A Retrospective Review and Prospective Overview

COVID-19 is an emerging disease that is a major threat to the global community. The main challenge in this disease is the lack of proper or proven medication. The drugs used to treat this disease are only for symptomatic treatment. Studies of other coronaviruses, such as SARS and MERS, suggest that quercetin has sufficient potential to treat COVID-19. Previous studies have shown that quercetin reduces the entry of the virus into the cell by blocking the ACE2 receptor, as well as reducing the level of interleukin-6 in SARS and MERS patients. Therefore, the aim of this review was to scrutinize the potential of quercetin as a drug in the treatment of COVID-19 from a molecular perspective.

Automated summary

COVID-19 poses a major threat to the global community due to a lack of effective medication. Quercetin has shown potential in treating COVID-19 by blocking virus entry into cells and reducing inflammatory response.
