Abstract

Green tea contains several antioxidants including polyphenols of the catechin. which have been shown to act in vitro and in vivo as anti-inflammatory. anti-viral and anti-tumor drugs. Prostaglandins (PGs) are a family of intercellular and intracellular messengers derived from arachidonic acid(AA) by phospholipase(PL) and cyclooxygenase(COX). These mediators exert a wide range of effects on processes such as smooth muscle tone. vascular permeability, cellular proliferation. and inflammatory/immune function. (omitted)
