Green tea extract is a popular ingredient in herbal weight loss supplements. There have been reports of hepatotoxicity associated with the use of dietary supplements, some of these cases lead to fatal outcomes. To our knowledge, we report the first case of fulminant hepatic failure requiring orthotopic liver transplantation caused by SlimQuick™ (Wellnx Life Sciences, Wilmington, DE), a widely a...

BACKGROUND Green tea has various health promotion effects. Although there are numerous tea cultivars, little is known about the differences in their nutraceutical properties. Metabolic profiling techniques can provide information on the relationship between the metabolome and factors such as phenotype or quality. Here, we performed metabolomic analyses to explore the relationship between the me...

Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disorder in which thelevel of oxidative elements in blood rises. Green tea is a potent antioxidant since it containscatechins. In this study, the effect of hydro-alcoholic green tea extract on PCOS rats was examined.For PCOS induction, 96 mature Wistar rats were given estradiol valerate. After 60 days, therats were divided into fo...

This perspective on Tsao et al. (beginning on p. 931 in this issue of the journal) discusses green tea extract, which was shown for the first time to have dose-dependent effects in a clinical chemopreventive setting (oral premalignant lesions). This translational trial provides important data on angiogenesis and other biomarkers on which to base future clinical research, which should include tr...

PURPOSE Green tea due to its content of catechins reveals strong antioxidative activity, which is manifested among others by its ability to inhibit free radical generation, scavenge free radicals as well as chelate transition metal ions that catalyse free radical reactions. The influence of green tea extract, epicatechin (EC), epicatechin galate (ECG) as well as epigallocatechin galate (EGCG) o...

We tested the hypothesis that green tea prevents diabetes-related tissue dysfunctions attributable to oxidation. Diabetic rats were treated daily with tap water, vitamins C and E, or fresh Japanese green tea extract. After 12 months, body weights were decreased, whereas glycated lysine in aorta, tendon, and plasma were increased by diabetes (P < 0.001) but unaffected by treatment. Erythrocyte g...

Epidemiological studies have shown that intake of tea catechins is associated with a lower risk of cardiovascular disease. The antioxidative activity of tea-derived catechins has been extensively studied. Reports have shown that green tea extract intake is associated with increased weight loss due to diet-induced thermogenesis, which is generally attributed to the catechin epigallocatechin gall...

This study was aimed to depict potential effects of stable formulation (water in oil emulsion), containing 3% green tea (Camellia sinensis L) extract on skin sebum production in healthy human volunteers. For this purpose formulation was designed using 3% ethanolic green tea extract and Abil®EM90 was used as an emulsifier. Formulation was applied to the cheeks of healthy human volunteers (n=10) ...

Background & Aims: The prevalence, incidence, and complications of heart disease increase with age. Green tea is an antioxidant which can prevent cellular senescence and cardiovascular diseases. Telomerase enzyme decreases with aging. Acute exhaustive exercise results in disturbances in the oxidative system and production of active oxygen species in the heart tissue. Thus, the present study aim...
