Tea polyphenols have the effect of promoting the growth and proliferation of many beneficial bacteria in the human intestinal tract, such as bifidobacteria.
3. Antiviral effect
Tea catechins have inhibitory effects on influenza viruses A and B.
4. Reduce lipids and lose weight, prevent and treat atherosclerosis

5. Antihypertensive effect
Tea catechins, especially ECG and EGCG, have obvious inhibitory effects on the angiotensin I converting enzyme.
