Green Tea:Other Effects and Applications of Green Tea.
Green tea polyphenols are potent antioxidants, especially in the brain. Some studies show that the polyphenols most prevalent in green tea (the catechins) are far more potent in suppressing free radicals than vitamins C or E.
Green tea can kill bacteria. Taking green tea with meals may reduce the risk of bacterial food poisoning. Drinking green tea may kill oral bacteria that cause cavities and bad breath. Green tea also is effective against a strain of staph that has become antibiotic-resistant. Green tea promotes the growth of friendly bifidobacteria in the intestine and prevents the growth of dangerous intestinal bacterial strains such as clostridia and E. coli.
The polyphenols in green tea suppress the production of an uremic toxin (methylguanidine) to improve the clinical appearance of the kidney after renal failure. A human study showed that the toxic compound methylguanidine decreased significantly one month after the administration of green tea polyphenols. Six months later, the mean methylguanidine level was about 70% of what it had been at the initiation of treatment.
The Chinese drink green tea to suppress foul breath caused by certain foods. The deodorizing effect of green tea leaves has been known for centuries, and tea leaves traditionally have been used as deodorants. A study demonstrated the deodorizing action of green tea polyphenols in a test against methyl mercaptan, the compound most closely associated with halitosis. Green tea also has been shown to suppress bad smells produced by trimethylamine and ammonia.
Green tea inhibits several viruses, including viral hepatitis. And, while high stores of iron preclude successful treatment of hepatitis C, green tea lowers iron levels throughout the body and may have a direct anti-viral effect against certain strains of the hepatitis C virus. Thus, green tea is highly recommended for hepatitis patients who may have too much iron in their livers. Further, iron interacts with the hepatitis B and C viruses to generate free radicals that cause cirrhosis of the liver. Excessive iron in the liver also precludes successful treatment with ribavirin and interferon.

Helps stabilize blood lipids. High triglycerides, hypertension. May actually lower the risks for arteriosclerosis. Improving the ratio of LDL cholesterol to HDL cholesterol. Reduces platelet aggregation
Eases mental fatigue and has been used in treating digestive tract infections:
This herb eases mental fatigue and has been used in treating digestive tract infections. The Chinese often use it to treat migraine headaches. It can also help to prevent plaque buildup on the teeth, and since the leaves contain a natural fluoride, may be helpful in preventing tooth decay. It can help to regulate blood sugar and insulin levels. Swiss researchers even have preliminary evidence that green tea accelerates the burning of fat calories in people who are overweight.
Green tea and its Cosmetic Uses:
Although many people are aware of the health benefits associated with drinking green tea, not that many are aware of the properties it exhibits when used in topical skin care preparations and cosmetics for protecting collagen from being broken down.Green tea is a potent anti-inflammatory agent thereby reducing inflammation in the skin, and most importantly having an inhibitory action on collagenase, which is a collagen-reducing enzyme that breaks down collagen.Other related effects of green tea for skin care majorly comes from below combined mechanism,and the useful components works for this purpose can be identified majorly as EGCC,Methylxanthines groups,Phenols.
(1).powerful neutralizing free radicals of Epigallocatechin galate (EGCC),thus protect the DNA of the cells from free radicals can attack and damage and prevent possible skin tumors and cancers,anti-aging;(2).Maintaining a firm and elastic skin by helps inhibiting collagenase,can be used topically to promote the health and quantity of collagen;(3).Methylxanthines contained in green tea also stimulates skin microcirculation and therefore positively influence the tone and health of the skin;(4).Green tea also exhibits a photo protective effect when applied to the skin and reduces erythema formation;(5).Phenol contents limited cell death when exposed to radiation, thereby showing that these polyphenols have a cell-protecting function as well.
Some glossary notes declared the cosmetic property of caffeine content from tea,One of a group of alkaloids called methylxanthines. It is a substance with a high tannin content, which constricts skin and can cause irritation. When consumed in coffee, caffeine can be a strong diuretic, but there is no evidence that this effect can result when caffeine is applied to skin (so it would not have the effect of "flushing away" fluid in tissues around the eyes that can accumulate as you sleep). However, there is research that caffeine can have anticancer benefits when consumed along with green or black tea (adding caffeine to the decaffeinated versions of the teas did not work as well as using the caffeinated versions of the teas). Whether there is any correlation between the effects of consuming caffeine and its effects when applied topically on skin is unknown.
Green tea leaf extract(Camellia Sinensis Leaf) rich in polyphenols such as EGCG that prevent free radical damage and tumor formation, reduces inflammation, inhibits destructive enzymes that break down healthy collagen fibers (improves firmness / elasticity), provides photo-protective benefits.From some glossary notes about the Green Tea Extract and other tea extract,The Journal of Photochemistry and Photobiology (December 31, 2001) stated that the polyphenols "are the active ingredients in green tea and possess antioxidant, anti-inflammatory and anticarcinogenic properties. Studies conducted by our group on human skin have demonstrated that green tea polyphenols (GTP) prevent ultraviolet (UV)-B induced immune suppression and skin cancer induction." Green tea and the other teas (such as white tea, which is what green tea begins as) show a good deal of promise for skin, but they are not quite the miracle that cosmetics and health food companies make them out to be. As the Annual Review of Pharmacology and Toxicology (January 2002, pages 25~4) put it, "Tea has received a great deal of attention because tea polyphenols are strong antioxidants, and tea preparations have inhibitory activity against tumorigenesis. The bioavailability and biotransformation of tea polyphenols, however, are key factors limiting these activities in vivo.
Green tea leaves may be applied in cosmetics for free radical inhibition and other antioxidant effects,dried leaves from the Camellia sinensis plant is processed into three types of tea: oolong tea, black tea, and green tea. In making green tea, the tea leaves are stabilized by moist or dry heat which destroys the enzyme polyphenoloxidase and thus, prevents oxidation of polyphenols. These polyphenols are the main biologically active ingredients in green tea. Catechins, a chemical group of polyphenols possessing antioxidant properties (protects cells from free radical-mediated damage), include epigallocatechin-3 gallate (ECGC), epigallocatechin, and epicatechin-3-gallate. Recently, ECGC has been shown to be an inhibitor of urokinase, and enzyme crucial for cancer growth (Jankun et al., 1997, Nature 387:561). The polyphenols in green tea, accounting for as much as 40% of tea's dry solids, have also been shown to reduce serum cholesterol and LDL (low density lipoprotein). Green tea polyphenols have been shown to prevent microbial (bacterial and viral) infections. For example, green tea polyphenols damage bacterial membranes (Dolby, 1997, Better Nutrition, 59:22). Further, extracts of green tea have been shown to prevent cancers of the lung, breast, prostate, liver, skin, esophagus, and colon. Green tea is also high in cavity-fighting fluoride--the amount of tea used to prepare one cup has approximately 0.3 milligrams of fluoride.
