Yellow tea is more potent than other types of tea in suppressing liver toxicity induced by carbon tetrachloride in rats.
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.
