There are several studies evaluating the clinical benefit of quercetin Australia . These include nine phase-2 clinical trials that evaluated quercetin vs. COVID-19. According to the National Institutes of Health database, four were completed while the results from one were published in a peer-reviewed journal. Although the results of these studies were preliminary, they do provide some insight into the potential benefits of quercetin in COVID 19. Quercetin inhibits NLRP3 inflammasome activation One of the most important aspects of COVID-induced inflammation is cytokine production. When these molecules are too abundant, they can trigger a cytokine storm. As a result, severe COVID-induced inflammation and oxidant/antioxidant imbalance can occur. Quercetin inhibits NLRP3 inflammasome activation by impairing the formation of oligomerization of the ASC. This means that quercetin prevents the production of IL-1b and IL-18. In addition, quercetin enhances IL-10 and HO-1 expressions, and...
