Both green tea and wu yi tea are very good for the body. They each contain vitamins and nutrients that help to protect the body from harmful free radicals and help improve your cholesterol. Both tea products come from the same source but the difference is where and how they harvested.

Nevertheless, these natural substances come in different concentrations in green tea and wu yi tea. The main reason for this is the different fermentation processes that these tealeaves undergo. Green tea is dried and packaged without fermentation. Wu yi tea, on the other hand, is semi-fermented. This means that wu yi undergoes a certain level of fermentation under the sun that of course affects its flavor, aroma and texture, and the concentration of substances in it as well.

There are very important substances in tea that are fantastic for good health such as: cathecin, polyphenols, flavin, and tearubigin, these are subcategorized and are in the tannin classification. The difference in the two types of teas is the amounts of these nutrients.

Wu yi tea and green tea contain about the same concentration of caffeine. Studies have concluded that caffeine is good for preventing type two diabetes, colon cancer, and parkinsons disease. Caffeine is no longer being scrutinized like it was before. It is actually quite good for you.

In the tannin sub-groups there are slight differences in green tea and wu yi tea. Green tea has higher levels of catechin than wu yi tea. Catechin is important in reducing the risk of diabetes, stroke, and heart failure. Catechins have been associated with delaying the aging process as well.

Meanwhile, wu yi tea has a slightly higher level of concentration of the tannin teaflavin and tannin tearubugin. These compounds are continually being studied because of their natural capacity to lower blood cholesterol levels, anti-oxidant properties, and capacity to prevent dementia in old age or AIDS cases.

Lastly, tannin polyphenols are significantly in higher levels of concentration in wu yi than in green tea. Polyphenols are known to reduce the risks of cancer, diabetes mellitus, degenerative diseases, cardiovascular diseases, osteoporosis, and others. It is a powerful form of anti-oxidant thus helps reduce cholesterol in the body, together with other toxic compounds that may be harmful to our health.
