Common Name(s): Tea , green tea , black tea , oolong tea , Veregen. Uses. Tea is traditionally consumed as a beverage. Evidence from clinical trials suggests that green tea plays a role in metabolic syndrome because it may have an impact on body weight, glucose homeostasis, and other cardiovascular risk factors. It has yet to be determined whether green tea is an agent in cancer prevention; however, a role in the prevention of stroke has been suggested. Topical applications have been studied for protection from ultraviolet (UV) damage, and a commercial preparation has been approved for use in the treatment of anogenital warts. Dosing. A daily intake of 3 to 5 cups/day (1,2. L) of green tea will provide at least 2. Green tea extract should not be taken on an empty stomach due to the potential for hepatotoxicity from excessive levels of epigallocatechin gallate. Anogenital warts : topical application of sinecatechins 3 times a day for a maximum of 6 weeks. Cardiovascular effect : 4. Diabetes : Dosages of epigallocatechin gallate range from 8.

Contraindications. Contraindications have not been identified; however, use caution when hepatic failure is present. Pregnancy/Lactation. The US Food and Drug Administration (FDA) advises those who are or may become pregnant to avoid caffeine. Interactions. Vitamin K present in green tea may antagonize the anticoagulant effect of warfarin. Green tea consumption reduces the bioavailability of folic acid and may interfere with the absorption of iron. Green tea may stop bortezomib (Velcade) from working properly. Green tea is the perfect complement to sushi, but it also happens to be a powerful fat burner loaded with beneficial antioxidants. Get the scoop! I love me some. Patients taking bortezomib should not drink green tea or consume any green tea products. Adverse Reactions. There are no reports of clinical toxicity from daily tea consumption as a beverage. Adverse events include headache, dizziness, and GI symptoms. Hepatotoxicity, including 1 fatality, has been associated with high plasma levels of epigallocatechin gallate or its metabolites. Toxicology. Multidose pharmacokinetic studies suggest a daily dosage of 8. High- dose oral green tea extract and catechins were hepatotoxic in rats. Botany. Black, oolong, and green tea are produced from the leaves of C. This evergreen shrub or tree grows to over 9 m in height and is pruned from 6. Its dark green, serrated- edged leaves are alternate and oval, while its white and fragrant blossoms appear singly or in clusters. Green tea is the dried leaf component, while black tea is produced by a complex wilting and fermentation process. Oolong tea is produced by a process intermediate to that of green and black tea. History. The dried, cured leaves of C. Traditional Chinese medicine has recommended drinking green tea for the prevention of ill health, and in Asia, this is still regarded as a healthy practice. Chemistry. The chemistry of tea is complex because of the numerous components that are formed during the curing and drying process, and variations aimed at producing various drinking teas, such as harvest season, climate, and horticultural and processing practices. Quality control and analytical methods are improving, allowing for more confidence in recent clinical studies. Tea leaves contain varying amounts of polyphenols (the majority of which are catechins) as well as smaller quantities of caffeine, theanine, theobromine, theophylline, and phenolic acids. Other tea constituents include tannins, essential oils, riboflavin, niacin, folic acid, ascorbic acid (which is present in fresh leaf but destroyed in making black tea), pantothenic acid, malic and oxalic acids, manganese, potassium, magnesium, and fluoride. The major polyphenol found in green tea is (- )- epigallocatechin gallate, with lesser amounts of catechin, epicatechin, gallocatechin, gallocatechin gallate, and epicatechin gallate. The composition of green tea, prepared by drying and steaming (to inactivate the oxidase enzyme), is very similar to that of the fresh leaf, except for a few changes that occur extremely rapidly following plucking. The primary difference between green and black tea derives from the fermentation process required to produce black tea. The catechins are converted to the higher molecular weight theaflavins (absent in green tea). Less fermentation results in an intermediary, lighter tea known as oolong tea. Decaffeination slightly reduces the catechin content of black tea, while herbal teas do not contain caffeine or catechins. The addition of milk to tea does not affect the bioavailability of catechins, but may alter the antioxidant potential, depending on the fat content. Uses and Pharmacology. Many of the health benefits of tea drinking are attributed to the antioxidant capacity of the chemical constituents 4 , 8 and are largely borne out by in vitro experiments and epidemiological studies. In vitro experiments show a direct effect of tea on reactive oxygen species and chelation of metal ions, such as iron and copper. Green tea is considered to be more active than black tea 3 , 8 with epicatechin and catechins ranking most potent of 2. The various methodologies of antioxidant experiments markedly affects the rankings. Most clinical trials demonstrate that tea consumption improves plasma antioxidant capacity and biomarkers of oxidative stress. Anogenital warts. In 2. 00. 6, the FDA approved a green tea–based ointment containing sinecatechin (polyphenon E) for the treatment of anogenital warts. Randomized, double- blind clinical trials have demonstrated the efficacy of the ointment ( Veregen ), which is considered to act via antiviral, immunomodulatory, antioxidant, and antiangiogenesis mechanisms. Cancer. Epidemiological studies and animal experiments have provided sufficient evidence of green tea's potential as an anticancer agent to warrant consideration, as demonstrated by the continued investigational interest in tea. Comprehensive reviews are available, but are limited in their findings because the studies included are too heterogeneous for meaningful comparisons. Long- term and case- control studies suggest an inverse association between tea consumption and the risk of cancer of the colon, urinary bladder, stomach, esophagus, lung, pancreas, prostate, and squamous skin cells. Increased risk of recurrence of breast cancer 9 and delayed onset of cancers in general have been described. Results of epidemiological studies differ due to factors such as social class and lifestyle. A Cochrane meta- analysis of the effects of green tea in cancer has found insufficient and conflicting evidence to support a preventative role. The observed anticancer effects are largely attributed to the catechins found in tea, while action on tumors by theanine may be due to enhancement of the immune response. A Cochrane review found no evidence suggesting the efficacy of green tea in preventing progression to malignancy in leukoplakia. Mechanisms for anticancer activity of green tea have been investigated in animal models and laboratory experiments, but not yet demonstrated in vivo in humans. Doses used experimentally may not reflect usual tea consumption, and there may be a combination of effects or a combination of active compounds acting to produce the relationships reported in epidemiological studies. The polyphenols in green tea inhibit cell proliferation. The polyphenol epigallocatechin gallate increases the activity of antioxidants in specific organs in mice and thereby increases the overall chemoprotective effect of antioxidants in those organs. Epigallocatechin gallate may also facilitate direct binding to certain carcinogens. Polyphenols, especially catechins may protect cells from tumor development by enhancing gap junction communication between cells. Tea has been shown to block tumor growth by sealing the receptors of affected cells. Polyphenols may assist inhibition of tumorigenesis in a variety of organs including skin, lungs, oral cavity, esophagus, stomach, small intestine, colon, liver, pancreas, ovary, and mammary glands. Green tea polyphenols induced apoptosis in a variety of cells, including human lymphoid leukemia and human prostate cells, 9 , 1. A risk of esophageal cancer from tea drinking has been suggested in epidemiological studies, but this has also been attributed to the scalding temperatures at which the beverage may be consumed. Cardiovascular effects. Epidemiological studies and in vitro experiments show that tea consumption is inversely associated with cardiovascular disease, although a direct cause- effect relationship has not been conclusively demonstrated. Mechanisms of action under investigation include reduced low- density lipoprotein (LDL) oxidation, enhanced endothelial cell functioning, hypotensive effects, effects on atherosclerosis, platelet aggregation, and improved cholesterol profiles. Cholesterol- lowering effects of tea have been investigated in numerous clinical trials, including healthy volunteers, as well as obese children and adults. A meta- analysis of trials up to June 2. A reduction in LDL cholesterol was found for green tea, but no effect on high- density lipoprotein (HDL) cholesterol was established. These results are based on a limited number of clinical trials, because inclusion criteria for the individual trials and test compounds used are often too heterogeneous for meta- analysis. Further trials evaluating effects on cholesterol and other cardiovascular markers showed decreases in total and LDL cholesterol for subgroups, 2. HDL cholesterol ratio. Hypotensive effects of green tea have been evaluated, with the meta- analysis reporting no effect for green tea and black tea increasing blood pressure, 2. Studies evaluating other markers of cardiovascular stress (inflammation and oxidative stress) include reported decreases in serum amyloid- alpha and malondialdehyde, 2.
