There are various legends of the origin of tea, but the most popular is the legend of Emperor Shen-Nung from Yunan province of China in 2737 BC. While it is cooking water drink, with a leaf accidentally coming from the dry wood he uses as fuel, fly and submerged into the water kettle. Water steeping the leaves are then produce a new beverage that smelled distinctly up to now known as a tea.

A good tea is produced from the shoots (pecco) plus 2-3 young leaves, because the young leaves are rich in polyphenol compounds, caffeine and amino acids. A number of these compounds which will affect the quality of color, aroma and flavor of tea.

The primary basis of tea processing is the use of the existing oxidation of polyphenol compounds in tea leaves. The oxidation process is commonly called fermentation.

Here are some properties of tea and usefulness:

Black tea (black tea),

Black tea easily recognizable in the market because it is black and the most widely consumed. In the process of fermentation occurs given a full opportunity (perfect chemical changes so that almost all the tannin content of fermented into theaflavins and thearubigin).

This fermentation process the tea leaves will change color from green to brownish and with the drying process to turn black.

A study published the Journal of Psychopharmacology showed evidence that black tea effectively reduce cortisol, stress hormones.

"The study found that people who drank black tea will be reduced stress more quickly than those who drank other types of tea," explained Bailey.

Furthermore, he said, participants experienced a decrease of cortisol levels in their blood after severe stress. The key, they consume black tea four times per day for six weeks. Black tea is also able to reduce the risk of cancer.

Oolong tea

Generally produced from the tea plant that grows in semi-tropical regions. The process is the same as black tea, fermentation process but only partially (about 30-70% faster and the change lasted half complete that still contain some tannins and some compound derivatives), so that the color and flavor in between black tea and tea green.

Oolong tea is proven to encourage the body's metabolism, burn fat, help lose weight, and maintain healthy skin.

'The woman who drank two cups of oolong tea a day increase their metabolism of approximately 157% more than women who drink green tea in the same amount,' said Bailey like quoting a study published in the Journal of Medical Investigation.

White tea (white tea)

Is the best type of tea due to get it, just taken from one shoot every single tree, which is the highest and the main shoot. Highest antioxidant content. In the process, tea leaves left to wilt naturally so that the color to white.

The quality of tea is a collection of properties owned by the tea, both physical and chemical properties. Both of these properties have been owned since I was a bud or obtained as a result of handling and processing techniques are performed.

White tea, white tea extract in particular proved to slow the growth of bacteria that cause Staphylococcus infections, Streptococcus infections, pneumonia, and dental caries, and improve immune system function.

"According to Milton Schiffenbauer PhD, professor of microbiology and biology at Pace University's Dyson College of Arts & Sciences, antiviral and antibacterial effects of several toothpaste brands is because of the additional extracts of white tea," Bailey added.

Green tea (green tea)

Tea leaf fermentation were not given the chance (almost no experience the process of chemical change). Usually the bud immediately processed with heat / steam to stop the enzyme activity so that the same as the raw leaf (originally tea leaves), so besides the color is still green are also still contains tannins that are relatively high.

Green tea is often used to reduce the risk of cancer and heart disease, lower cholesterol, lose weight (especially abdominal fat). Green tea also beneficial in lowering risk of diabetes and Alzheimer's.

In addition to body health giving properties, tea also has a content of chemical compounds consisting of three major groups, each of which have health benefits, namely:


Tea polyphenols in the form of catechin and flavanols. These compounds act as antioxidants for the capture of free radicals in the body is also effective in preventing the development of cancer cells in the body. Free radicals in our bodies because of the polluted air environment pollution and also of the food we eat.


Elements of caffeine in tea than coffee fewer that are as mild stimulant on the central nervous system that facilitate blood circulation to the brain. By drinking tea regularly will increase the level of memory, cognitive performance, and the feeling of pleasant mood.
