There are a variety of phytochemicals present in the leaves of the Camellia sinensis plant and some of them like Catechins, Theaflavins and Myricetins have demonstrated their efficacy as antivirals against the SARS-CoV-2 coronavirus in vitro studies involving Vero E6 cells.

In particular the identified phytochemicals that have shown to have efficacy by the inhibition of SARS-CoV 3C-like Protease activity as demonstrated by both molecular docking studies and also by vitro studies involving Vero E6 cells are Myricetin 3-O-beta-D-glucopyranoside, Theaflavin-3,3′-digallate (TF3) and Epigallocatechin Gallate.
 
Before anyone assumes that merely drinking cups of green tea is going to treat COVID-19, we have to warn you that this is not the case as the phytochemicals need to be extracted out properly and the green tea needs to be pre-treated in a proper manner to get the right phytochemicals seeping out when brewed etc. Also, the right quantities of these phytochemicals are needed to demonstrate any efficacy.It should also be noted that no vivo studies and human trials have been done yet to treat COVID-19 using these phytochemicals from green tea.
