Tea improves endothelial function
The endothelium, or inner lining of the arteries, plays a central role in the proper functioning of arteries.
Endothelial cells produce factors which affect blood flow in a vessel, coagulation of blood and also serve as a barrier that controls the diffusion of liquids and solutes between blood and vessel wall.
It has been recognized that endothelial dysfunction is associated with an increased risk of cardiovascular diseases.
Recent scientific investigations have found that both short-term and long-term tea consumption improves the endothelial function, reducing the risk of heart disease.
