The Effectiveness of Phytotherapy in SARS-COV2(COVID-19)

Quercetin is one of the flavonoids. Quercetin as well as rutin are recognized to be among the most active of the flavonoids. It is to quercetin that several medicinal plants, including ginkgo and St. John's Wort, owe part of their therapeutic effects. Often combined with vitamin C in supplements, it improves absorption by the body and delays its elimination. Quercetin is extracted from a variety of plant sources, including the onion peel and seeds and pods of Dimorphandra mollis, a tree in the legume family native to South America. At present, there is no scientific data to demonstrate the effectiveness of herbal medicine, regardless of the plant, to prevent or treat COVID-19. On the other hand, some plant-based food supplements have anti-inflammatory or immunomodulatory properties that may disrupt inflammatory defense mechanisms useful in fighting infections, and in particular against COVID-19.
