Use of Quercetin for Therapeutic Purposes in COVID-19 Infections: The Opinion of the Geriatrician Doctor

The COVID-19 epidemic has put health systems around the world in distress, at the same time stimulating global research in an attempt to discover new therapeutic strategies against this virus. In this opinion we analyze the characteristics of a flavonoid, quercetin, trying to better understand its usefulness in the treatment of coronavirus infection.
