Nutraceutical is anything i.e. food or a component of food having health or medical advantages, including the treatment and prevention of disease. These products have been used to improve health, delay the onset of chronic conditions, postpone ageing, prolong mortality rates, defend against disease or improve the structure or functioning of the body.

The present review was carried out to congregate the benefits of polyphenols such as rutin, hesperidin lactoferrin against SARs-Co-V-2, Enterovirus, Influenza and Human papillomavirus (HPV). The data manifest that polyphenols through various mechanisms such as direct binding to virus, binding with heparan sulfate proteoglycans, intracellular inhibition of viral replication or by enhancing effects of T and NK 20 lymphocytes inhibits virus growth. The review was carried out using scientific search engines such as Google scholar, PubMed, Science direct, Medline and Science. Gov.
