Cellular Physiology and Biochemistry.The study revealed that green and black tea have two catechin-type flavonoid compounds (epicatechin gallate and epigallocatechin-3-gallate).
Both of these compounds activate a certain ion channel protein called KCNQ5. This causes potassium ions to disperse out of cells, which lowers cellular excitability.The smooth muscle inside blood vessels contains KCNQ5, which becomes activated by catechins in green and black tea.
Researchers, including collaborators at the University of Copenhagen, believed this could also relax blood vessels.Dr. Abbott said this:Around one-third of the global adult population suffers from high blood pressure.Read more on powerofpositivity.com
