Description:

Archeological evidence suggests that tea leaves steeped in boiling water were consumed as many as 5,000 years ago. Botanical evidence indicates that India and China were among the first countries to cultivate tea. Although the English are known for their love of tea, Americans invented the tea bag and began the practice of drinking iced tea in the early 1900s. Today, hundreds of millions of people drink tea around the world, and studies are now suggesting that one variety of tea in particular -- green tea (Camellia sinensis) -- has many health benefits.

Among populations in China and Japan, where high amounts of green tea are consumed daily, cancer rates are statistically lower. There is now growing scientific research from reputable sources that shows promising results as to how the active ingredients in green tea might be responsible for lowering rates of various kinds of cancer.

Green tea extract is derived from leaves of camellia sinensis. It is associated with several health benefits, many supported by preliminary scientific research. This includes potential cancer-fighting properties, and a strong antioxidant effect that protects the body from the damaging effect of free radicals.

 

Chemical constituents of Green tea extract 

The chemical composition of green tea varies with climate, season, horticultural practices, and age of the leaf (position of the leaf on the harvested shoot). The major components of interest are the polyphenols. The term polyphenol denotes the presence of multiple phenolic rings (A phenolic ring is a 6-carbon benzene ring with an attached hydroxyl (OH) group -- also referred to as the hydroxyl functional group). The major polyphenols in green tea are flavonoids (e.g., catechin, epicatechin, epicatechin gallate, epigallocatechin gallate (EGCG), and proanthocyanidins). Epigallocatechin gallate is viewed as the most significant active component. The leaf bud and first leaves are richest in epigallocatechin gallate. The usual concentration of total polyphenols in dried green tea leaves is around 8 to 12 percent.
