Some Green Tea Leaf Extract Studies

Green Tea Study 1: In a study conducted by the University of North Carolina, Zhi Zhong and colleagues studied the free radical scavenging effects of green tea leaf extract on problems associated with fatty livers. The study involved drunk rats that went through "binge drinking" and then put to sleep with their livers removed. Some of these livers were bathed in a green tea extract solution.

These livers were then transplanted into rats with unhealthy livers. The study found that only 13% of the rats that received livers untreated with green tea survived, while 77% that had received a liver treated with green tea extract had survived.

Green Tea Study 2: In a research studying the effects of green tea on treating acne, researcher Gan Wong et al. (Memorial Medical Center in the Philippines) compared the effects of 3% green tea cream and 4% benzoyl peroxide on moderate to severe acne.

108 subjects were randomized into 2 treatment groups: 1) benzoyl peroxide cream and 2) green tea extract cream, and the creams were applied twice daily for 12 weeks for the 2 groups. The study found the green tea cream to lighten patient's skin color and improve overall skin complexion. The study also suggests that green tea extract cream causes fewer side effects than benzoyl peroxide, and the green tea group reported fewer cases of dry skin, itching, and allergic responses.
