Legend in China says that tea was discovered accidentally by Shen Nong, the divine cultivator, around 3000 B.C. He is credited with inventing agriculture and Chinese herbology. One day, leaves of the tea plant fell into water he was boiling outside his house. He liked the drink, found it to be a healthful beverage, and tea was born. Considerable research on green tea has shown it to be high in polyphenols, a group of powerful antioxidants. Experts recommend drinking three or more cups of green tea a day. Make this healthful tea a part of your daily diet, just as Asian people do. Enjoy it hot or iced.
