Tea to human health caused by the multifaceted role in the protection of people have been known. Recently, the U.S. scientists of green tea and black tea has done further study shows that the two Zhongcha have slowed the spread of prostate cancer, and the red wine and peanuts are rich in antioxidant substances are not an effective anti-cancer effects.

In this study, the researchers let 20 patients with prostate cancer in the prostate cancer surgery five days before drinking tea, or green tea, or soda, five cups a day.
