The secret of green tea lies in the fact it is rich in catechin polyphenols, particularly epigallocatechin gallate (EGCG). EGCG is a powerful anti-oxidant: besides inhibiting the growth of cancer cells, it kills cancer cells without harming healthy tissue. It has also been effective in lowering LDL cholesterol levels, and inhibiting the abnormal formation of blood clots. The latter takes on added importance when you consider that thrombosis (the formation of abnormal blood clots) is the leading cause of heart attacks and stroke.
Green tea versus green tea extract. We believe there are many benefits to drinking green tea every day. It gives you all the benefits of green tea. It gets more water into your system. It makes your tummy feel full. It is a comforting ritual. However if you are not able to enjoy the actual green tea beverage, you may still get some of the benefits by taking green tea extract in supplement form.
Many varieties of green tea have been created in countries where it is grown that can differ substantially due to variable growing conditions, processing and harvesting time. Over the last few decades green tea has begun to be subjected to many scientific and medical studies to determine the extent of its long-purported health benefits, with some evidence suggesting regular green tea drinkers may have lower chances of heart disease and developing certain types of cancer.
While green tea polyphenols have been shown to inhibit the growth of human lung cancer cells in test tubes, few studies have investigated the link between green tea consumption and lung cancer in people and even these studies have been conflicting. One population-based study found that Okinawan tea (similar to green tea but partially fermented) was associated with decreased lung cancer risk, particularly among women. A second study revealed that green tea and black tea significantly increased the risk of lung cancer. As with colon and esophageal cancers, further studies are needed before researchers can draw any conclusions about green tea and lung cancer.
When using green tea as a hot drink; you are advised to use it prior sleep when the metabolism is slowing down. Weight loss products containing this product can take some getting used too and often there may be some bowel irritation for a couple of days but it will pass. Some people are worried about this reaction but this is how green tea weight loss supplements work, by making adjustments to the body's metabolic rate. Providing you stick to your diet which would include exercise, an increase in fluids and vegetables you will see benefits within seven days of starting your diet.
Disease-preventing function by preventing high blood pressure or diabetes, (3) disease-recovery function by inhibiting the rise of cholesterol.

Ordinary tea, as most people know it, comes from the leaves of the camellia sinensis plant. There are three main types of tea: green tea, oolong tea, and black tea, categorized according to their oxidation levels (called the fermentation process). Green tea is steamed, baked, or pan heated to prevent oxidation and thus the leaves remain green. Unlike green tea, oolong tea is partially fermented, and black tea is fully fermented.
