Components making green tea an effective cure

The basic compounds making green tea extremely effective for curing a number of ailments are catechin polyphenols, more specifically epigallocatechin gallate (EGCG), a type of anti-oxidants. They have been proven to be quite effective in fighting and curing the growth of cancer in the human body. They carefully kill the cancer spreading tissues, while protecting the healthy ones from any kind of harm. Moreover, green tea reduces the level of cholesterol in our body and cleans our blood, so that the clots, sometimes formed in the blood vessels, are dissolved allowing the blood to flow easily. The formation of clots in the veins is one of the most popular reasons why people suffer from strokes and heart attacks.

For many years, scientists had been interested in finding about the secret behind the health of French people, despite their high intake of fatty food. It was then discovered that the red wine they used to consume, contained an ingredient known as resveratrol, a substance for minimizing the effects of smoking, as well as the fat intake. It was later discovered that the ingredients in green tea were twice as strong as the resveratrol. Thus, it is one of the reasons why Japanese people are successfully living a longer life, despite a large number of smokers among them.


Green tea, thus, provides an effective method to fight against various diseases. The leaves of black tea are basically fermented leaves which convert EGCG to other elements in the fermentation process, diminishing the effectiveness of the useful compounds. While green tea processing avoids the whole fermentation process to preserve its natural compounds and benefits.
