| Epigallocatechin-Gallate, also known as EGCG, has  powerful antioxidant properties and is a component of green tea, as well as  many nutritional supplements. It does appear in black tea, but at a much  smaller concentration, because black tea leaves undergo fermentation, changing  many of the catechins. Here are facts you may not know about this powerful  weapon against many of the toxins in your body. 
                    EGCG can help in fighting cancers of the       bladder, cervix, prostate and brain by surrounding molecules of a certain       protein that helps cells (both cancerous and noncancerous) thrive.ECGC reduces the various plaques that can       cause AIDS-based dementia. However, these results have only occurred in       the laboratory, with no human trials yet. What is certain though, is that       the ECGC dosage would have to be significantly higher than what is found       in green tea.ECGC provides protection against several       autoimmune diseases like Sjoegren's syndrome, primarily by alerting the       body's immune system to the dangers of TNF-alpha proteins, which cause       inflammation throughout the body.Some studies have shown that ECGC can protect       your DNA from mutating after exposure to visible and ultraviolet       radiation.ECGC may be a useful component in reducing       body weight and oxidizing body fat. It also has reduced glucose levels in       mammal studies, with human trials still in the development phase.ECGC may be able to prevent the joint       destruction that accompanies rheumatoid arthritis, because of its compatibility       with synovial fibroblasts.ECGC has shown the ability to limit the       development of mutant proteins that cause the progression of Huntington's       disease.Liver inflammation associated with hepatitis       would happen at a much slower rate with an ECGC regimen, according to a       mammal-based study.Human bones also can benefit from an ECGC       regimen. A study at the University of Toronto connected a rise in       mineralized bone nodules with regular doses of ECGC.                    Even though the benefits are strong, ECGC also has  some potential downsides – any supplement that alters body chemistry possibly  could cause harm in some manner. And while ECGC does have much promise, many of  the benefits have been observed in mammalian studies – but not in live human  trials. So while there is room for optimism, it's a bit early to order green  tea by the drum. First, you can experience insomnia or anxiety if you ingest too  much caffeine from the tea, although caffeine-free forms of green tea are  available. Possible issues to be considered are;
 
                    Pregnant and nursing women should not consume       green tea. There is a risk of malignant tumors in the central nervous       system for children whose mothers consumed green tea during pregnancy, and       neonatal leukemia is also a risk for infants whose mothers drank green tea       at high levels.Another possible danger associated with ECGC       is its interaction with Velcade, a common cancer-fighting drug. The       chemical bonding between the medicine and ECGC robs the medicine of any       benefit.                   As with many nutritional supplements, it is always  best to consult with your doctor before beginning an extended regimen |
