Pomegranate peel extract has been found helpful at preventing access of the SARS-CoV-2 virus to ACE2 receptors in a cell based study (in vitro). The pomegranate peel extract would contain mixed plant phytonutrients that might include EGCG, ellagitannins and gallotannins. The extract also inhibited “the activity of the virus 3CL protease.” (Tito, et al, 2020)
“In this study, by using different in vitro approaches, we uncovered the role of a pomegranate peel extract in attenuating the interaction between the SARS-CoV-2 Spike glycoprotein and the human Angiotensin-Converting Enzyme 2 (ACE2) receptor, and in inhibiting the activity of the virus 3CL protease.” (Tito, et al, 2020)
Ellagitannins and gallotannins are hydrolyzable tannins and have been found to have anti-viral effects against the herpes simplex virus. (search results ellagitannins antiviral)
