Description

White tea contains high levels of catechins, some of which reduce the occurrence of artherosclerotic plaques and the severity of strokes and prevent cancer in non-human studies.

Catechin is a flavan-3-ol, a type of natural phenol and antioxidant. Electrochemical experiments show that (+)-catechin oxidation mechanism proceeds in sequential steps, related with the catechol and resorcinol groups and the oxidation is pH-dependent. The oxidation of the catechol 3 ′ ,4 ′ -dihydroxyl electron-donating groups occurs first, at very low positive potentials, and is a reversible reaction. The hydroxyl groups of the resorcinol moiety oxidised afterwards were shown to undergo an irreversible oxidation reaction.

Tea Polyphenols  White tea is made from unfermented leaves and reportedly contains the highest concentration of powerful Antioxidants called polyphenols. Antioxidants are substances that fight free radicals -- damaging compounds in the body that change cells, damage DNA, and even cause cell death. Many scientists believe that free radicals contribute to the aging process as well as the development of a number of health problems, including cancer and heart disease. Antioxidants such as polyphenols in green tea can neutralize free radicals and may reduce or even help prevent some of the damage they cause.
