Green Tea Extract (EGCG) and COVID-19 Review
Green tea is a hot drink made with the same type of leaves as black tea, but the leaves are processed without the withering and oxidation used to make black tea. This results in a different set of healthy polyphenols in green tea as opposed to black tea. Green tea is high in epigallocatechin gallate (EGCG) and other catechins; black tea has some EGCG, but it also offers theaflavin, found only in regular black tea. The decaffeinated versions of green tea and black tea have far less of the healthy polyphenols, far less EGCG, catechin, and theaflavins. So the caffeinated versions of green tea and black tea are much healthier. There are many studies showing the benefits of drinking green tea . But you can only drink so much caffeine.
