Recently research has found that the EGCG has the potential to prevent and treat new coronavirus infections. EGCG and ECG in tea have a significant inhibitory effect on many influenza viruses in MDCK cell culture, and for influenza A virus. In addition, all three derivatives showed an inhibitory effect on the influenza virus. EGCG can resist adenovirus through various mechanisms in cells. The typical symptoms caused by the new coronavirus are the "inflammatory storm" caused by the spread of the virus and the body's excessive immune response. Therefore, inhibiting the inflammatory response is an important consideration in the treatment of patients with new coronavirus infection. Coincidentally, the active ingredient EGCG in tea can just relieve inflammation and inhibit the response of the disease from the root.
