Black Tea for Health -  Detoxify Heavy Metal and Increase Blood Flow

Black tea, green tea, oolong tea and white tea are four of the most famous teas in China. Though black tea uses the same leaves as green tea, they taste tremendously different because of the different processing methods. Black tea is well fermented, during which tea polyphenols react with the enzymes, giving black tea its mild flavor. Fun fact: Since black tea water appears to be orange or red, people in China generally call it red tea whereas in English it is referred to black tea.

It’s well-known that green tea helps improve digestion and reduce fat--not only can black tea do the same, but also it has some unique benefits of its own, including detoxifying heavy metal, diminishing inflammation and so on.

Caffeine and aromatic substances help increase blood flow to the kidneys, and dilates the kidney vessels. Therefore, kidney tubules are restrained reabsorbing water, and lactic acid, uric acid and other wastes can be excreted more quickly.

The polyphenols can also diminish inflammation. Some studies have shown that catechins in black tea can coagulate protein in pathogenic bacteria to distinguish them. In the southern areas of China, people use black tea to heal wounds and pimples. In some areas of heavy precipitation, people wash their feet with tea water to prevent beriberi.

Scientists mixed together tea water with the mercury solution, and found out the mercury started to settle over time.

Black tea helps strengthens the bones, too. The polyphenols can neutralize the substances that damage bone cells. According to a study conduced by the American College of Physicians following 497 males and 540 females for a ten year period, black tea helps prevent osteoporosis--adding some lemon to the water can enhance the effect.

Over the past decade, urban citizens have seen the risk of getting angiocardiopathy substantially increase. Black tea can improve blood circulation and decrease blood pressure.
