The thermogenic effect of tea is generally attributed to its caffeine content. An article in Alternative Medicine Review reports that green tea extract stimulates brown adipose tissue thermogenesis to an extent which is much greater than can be attributed to its caffeine content alone.

Research reported in the Journal of Nutrition demonstrates that EGCG can protect mice against carcinogen induced breast tumors. The green tea polyphenol significantly decreased mammary tumor burden and invasiveness and significantly increased latency to the first tumor.
In studies conducted on human skin, green tea polyphenols prevented ultraviolet (UVB) induced chemical changes in the skin, which are considered to be mediators of UVB induced immunosuppression and skin cancer induction. GTP treated humans can prevented penetration of UV radiation, and protected against UVB-induced local as well as systemic immune suppression in laboratory animals. […]
Recent research published in the American Journal of Physiology Endocrinology And Metabolism describes wide-ranging cardiovascular protective functions of a green tea polyphenol, EGCG. EGCG improved endothelial function and insulin sensitivity, reduced blood pressure and protected against myocardial ischemia and reperfusion injury. The addition of improvements in insulin sensitivity to the cardiovascular benefits indicates the benefit […]
The green tea flavonoid EGCG has potential therapeutic value for treatment to for HIV-1 infection EGCG binds to the CD4 molecule on T-cells according to research conducted in 2006. “We have demonstrated clear evidence of high affinity binding of EGCG to the CD4 molecule. EGCG has potential use as an adjunctive treatment in HIV-1 infection.” […]
Green tea is the fourth most commonly used dietary supplement in the United States. After the publication of adverse event case reports involving green tea products and potential liver toxicity, the US Pharmacopeia reviewed safety information for green tea products. 216 case reports on green tea products were analyzed including 34 reports concerning liver damage. […]
Just to keep things in perspective, the previous item about green tea extracts potentially causing liver problems must be balanced against research showing that green tea is protective against liver disease. Chinese researchers a value weighted interventional and observational studies in both Western countries and in China published between 1989 and 2007. They found “a […]
Japanese researchers explored the effect of tea catechins and regular exercise and the aging associated declining physical performance in mice. The endurance capacity of mice as measured by running time decreased by 17% in control mice, while those fed green tea catechins (0.35%) suffered no decline in endurance. The authors concluded “long-term intake of catechins, […]
Scientists in Taiwan studied the effect of green tea extract on 78 obese women aged 16 to 60 years. They found no significant improvement in body weight, body mass index and weight circumflex. There were significant improvements in LDL cholesterol and triglyceride. Effect of green tea extract on obese women: A randomized, double-blind, placebo-controlled clinical […]
Green tea polyphenols have been reported to preserve tissues such as blood vessels, corneas, nerves, islet cells, articular cartilage, and myocardium. Research in Japan examined the effects of EGCG on skin preservation. Utilizing epidermal and dermal skin cells in culture, the researchers report that the tea polyphenol helped to preserve the skin cells for up […]
