Hypertension is a common human disease and is a clinical syndrome characterized by continuous increase in arterial blood pressure. It has been proved that catechins (especially ECG and EGCG) and theaflavins in tea have obvious inhibitory effects on the activity of angiotensin I converting enzyme.

Drinking more green tea at the same time is beneficial for people who are prone to stroke and vascular congestion, because it can keep blood vessels elastic, eliminate vasospasm, and prevent blood vessel rupture.

In addition, caffeine and catechins in tea can relax blood vessel walls, increase the effective diameter of blood vessels, and reduce blood pressure through vasodilation.
