The present study compared the effects of six Chinese teas categorized by their production process: green, white, yellow, oolong, black and pu-erh teas, on carbon tetrachloride (CCl4)-induced liver injury. Wistar rats were given ad libitum the Chinese teas prepared according to the home-style methods for 1 week, and then intraperitoneally injected with CCl4 (1 mg/kg body weight) or olive oil as a vehicle. The yellow tea significantly ameliorated the increase in the activity of the alanine- and aspartate-aminotransferases in plasma. Thus, the drinking of yellow tea may contribute to protection against liver injury. Copyright 2007 John Wiley & Sons, Ltd.
