Therapeutic Potential of Tea

Several methods have been used to assess the antioxidant capacities of tea and tea polyphenols. An oxygen radical absorbance capacity 

The first report indicating the relationship between human cancer and tea was published in 1966 [72]. Since then, countless studies have been conducted and it has been revealed that polyphenols potentially induce apoptotic cell death in tumor cells, but do not affect normal cells [73], 

CVDs are associated with higher amounts of cholesterol in the blood. The major causes of heart diseases include stress, high intake of refined sugars or oils, and constant consumption of animal fats [89]. In coronary disease, initially atherosclerotic plaques originate in the arteries, which become narrower towards the lumen, resulting in a decrease in blood flow. Initially, low density lipoproteins (LDL) deposit at scratched sites in the arteries and become oxidized after the depletion of protective substances (tocopherols). With the oxidation of LDL, the lipoproteins are oxidized and stimulate inflammatory reactions. Consequently, this 

The protective effect of black and green tea against cardiovascular diseases has been considered to involve a combination of various mechanisms. These might include antioxidant, anti-inflammatory, antiproliferative, and anti-platelet effects. [8]. As mentioned earlier, LDL oxidation is the major step in the development of atherogenesis [102], A number of clinical trials have suggested that antioxidant supple- 

Another important aspect of the mechanism of tea in controlling cardiovascular diseases is the positive effects on endothelial functions. Abnormalities in endothelial function lead to several disorders, including CVDs. The daily consumption of black tea (900 ml/day) for 4 weeks improved the endothelium-dependent flow-mediated dilation of the branchial artery associated with coronary artery disease [100]. Similar effects on branchial artery dilation have been reported with green tea

Chapters 8-11 are devoted to consideration of two main classes of phytochemicals Chapter 8 centers on organosulfur compounds from the Allium genus, and their role in cancer prevention, while subsequent chapters are devoted to polyphenols and their wide-ranging effects against cancers, cataracts, and cardiovascular disease. Chapter 9 examines the cancer-protective and therapeutic potential of polymethylated flavonoids such as occur in citras, while Chapter 10 summarizes recent cancer chemopievention research in an area particularly relevant to the British and Chinese backgrounds of the editors, notably tea. A much less well-studied area, that of cataracts and their prevention by dietary flavonoids, is presented in Chapter 11.

Green and black teas are associated with numerous health benefits. The main factor responsible for the effective therapeutic potential of both teas is attributed to catechins and theaflavins. The catechins and theaflavins vary in their structures and properties [11]. Among cate-...

The potential health benefits of tea consumption are attributed to the sensitive water-soluble nutraceutical compound EGCG. But, EGCG faces the issue of instability in neutral and alkaline pH and fast degradation with oxygen, temperature, and pH changes [148]. This necessitates a suitable vehicle for the controlled release of EGCG, thereby enabling it to carry out its therapeutic activities. 

These properties could provide additional preventive/therapeutic effects toward psoriatic lesions. Thus, the potential use of green tea constituents as an alternative nontoxic preventive agent or therapeutic component to treat psoriasis and other skin disorders needs to be explored. 

N-Aminoalkylation of l//-pyrrole was achieved with 2-chloroethylamine under phase-transfer conditions (TEAS, NaOH, MeCN) <2004JOC8668>. Synthesis of N-alkylated indoles 121 (e.g., RO 60-0175, R = 5-F-6-Cl), that are selective 5HT2C agonists with potential therapeutic utility in the treatment of obsessive compulsive disorder... 

No particular therapy is effective. It is not known whether the minute quantities of phytomenadione that are present in some foods, such as parsley, kale, brussels sprouts, spinach, cucumber, soy bean oil, and green and black tea leaves, preclude effective dietary therapy. Since the mechanism of this reaction is thought to be delayed hypersensitivity, another potential therapeutic approach is topical application of tacrolimus (FK-506), a potent inhibitor of interleukin 2 and T cell activation. Tacrohmus up to now has only been shown to suppress allergic contact dermatitis to dinitrophenol.
