MEDTECH Tea’s Triumph: Green, Matcha, and Black Tea Display Potency Against Omicron Subvariants
A recent study conducted in Japan has shed light on the potential of common beverages in combating the COVID-19 Omicron subvariants. The research highlights the virus-inactivating properties of green tea, matcha, and black tea, providing a novel perspective on everyday items in our fight against the pandemic.
Key Points
- The study demonstrated that green tea, matcha, and black tea can effectively inactivate Omicron subvariants.
- Specific amino acid changes in Receptor Binding Domains (RBDs) play a substantial role in the binding of Epigallocatechin gallate (EGCG)/Theaflavin Digallate (TFDG) to the RBDs and the sensitivity of each Omicron subvariant to EGCG/TFDG.
- Saliva produced after consuming candy containing green tea or black tea exhibited virus-inactivating properties in vitro, rendering the virus less contagious.
According to a study by Kingston University and Neal’s Yard Remedies, green tea could potentially outperform many other plant extracts when it comes to antioxidant activity.
