Green tea ('Sencha'), made from the leaves of Camellia sinensis, is the most well-researched antioxidant beverage. The major source of its antioxidant activity is polyphenols, consisting mainly of catechins (flavan-3-ols). However, little is known about the physiological effects of green tea aroma, which lacks catechins. In the present study, we performed inhalation experiments with green tea a...

In its essence, tea is an infusion of Camellia sinensis leaves and it is the most widely consumed beverage in the world, aside water. Animal and epidemiological studies have associated green tea consumption with several health benefits, which include hypocholesterolemic effect and anti-inflammatory activity. In this study catechins levels of green tea and its effect on the lipid profile of huma...

Green tea is a commonly consumed beverage in China. Epidemiological and animal data suggest tea and tea polyphenols may be preventive against various cancers, including breast cancer. Catechol-O-methyltransferase (COMT) catalyzes catechol estrogens and tea polyphenols. The COMT rs4680 AA genotype leads to lower COMT activity, which may affect the relationship between green tea consumption and b...

After water, tea is the world’s most widely consumed beverage. Tea is enjoyed by many people for its cooling and slightly bitter flavor and is known to have many particular health benefits [1-3]. There are several types of tea according to its fermentation processes such as black tea, oolong tea, white tea, yellow tea and green tea [4,5]. Green tea is, like many another type in general and gree...

Green tea (Camellia sinensis) is one of the most widely consumed beverages in the world. The cancer chemopreventive qualities of green tea have been well documented. Epigallocatechin gallate (EGCG) is often described as the most potently chemopreventive green tea catechin; however, the low bioavailability of EGCG is a limiting factor for its biological effect. Thus, the aim of this work was to ...

In this study, we investigated the effects of various temperatures between 140 to 260 degrees C during sub-critical water extraction of residual green tea in making a roasted green tea-like extract, a popular beverage in Japan. Each residual green tea extract was analyzed for sensory properties and antioxidative activities, and this revealed 140 degrees C to be the best extraction temperature. ...

Over the past decade, teas and their molecular components have received increasing attention from researchers in human health. After water, tea is the most widely consumed and popular beverage in the world. It has a cooling effect, slightly bitter and astringent flavor which many is enjoyed by people and its medicinal properties have been widely explored. In addition, its content of certain min...

Background: Green tea has been used as a daily beverage for several years. Anti-inflammatory effect of tea has also been depicted in different papers. Therefore we had set forward this study to examine the potential antiinflammatory activity of green tea in small intestine mucositis experimental models. Aims: Evaluation of antiinflammatory effects of green tea on mice. Materials and Methods: Gr...

Green tea is a daily beverage, a non-oxidized non-fermented product containing at least four green tea catechins. Considering our first results when repeated applications of (-)-epigallocatechin gallate (EGCG) prevented tumor promotion in mouse skin, we have continued to look at green tea as a possible cancer preventive agent. 1) The 10-year prospective cohort study by Drs. K. Nakachi and K. Im...

Objective: Tea, camellia sinensis, which is used as a popular beverage in Iran, may reduce the risk of cardiovascular diseases suchas coronary heart disease (CHD). In this investigation, we studied the effect of Iranian black and green tea on serum and liver lipid profile which is closely associated with obesity and many cardiovascular diseases. Materials and Methods: 24 male adult Wistar rats...
