Description:Catechins are first extracted from catechu. It is a colorless crystalline solid; soluble in water; its aqueous solution is easily polymerized into amorphous tannins when heated or in the presence of inorganic acids. [1] and caffeine belong to the two major functional components of tea, but also the main component of tea catechins. According to clinical investigation, catechin can through the blood circulation to the body, strengthen the The new supersedes the old. enhanced oxidation and energy, fat consumption and thus inhibit the role of obesity, especially the inhibition of visceral fat, lose weight can reach the ideal effect.
