Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Pharmacy - Department of Pharmaceutics Summary: The difference between the teas is in their processing. Green tea is made from unfermented leaves and is reputed to contain the highest concentration of polyphenols, chemicals that act as powerful antioxidants. The more the leaves are fermented the lower the polyphenol content and the higher the caffeine content. Antioxidants are substances that scavenge free radicals (damaging compounds in the body that alter cell membranes, tamper with DNA (genetic material), and even cause cell death. Free radicals occur naturally in the body, but environmental toxins (including ultraviolet light, radiation, cigarette smoke and air pollution) can cause increase in the number of these damaging particles. Free radicals are believed to contribute to the aging process as well as the development of a number of health problems including cancer and heart disease
