As one traditional Chinese tea,white tea has a long history. But compare with green tea and black tea, white tea is not that famous. Recently, the topics of white tea are becoming increasingly popular among tea lovers from all over the world, due to some researches that relate to the healthy benefits of white tea.
University of Kyoto hospital had launched a program, which aimed for finding out the relationship between white tea and diabetes. After observing 100 patients with diabetes who drunk white tea regularly, they found that white tea significantly relieved the symptoms of diabetes. And they also found the reason of why white tea good for patients with diabetes: White tea contains the tea polyphenols that could help to lower the glucose level of blood.
Beside the research from University of Kyoto hospital, one article named “The sterilization effect of white tea is better than that of green tea”, which published on the “Science journal”, at May 28th in 2004, showed that the tea polyphenols inside white tea could prevent the growing of many kinds of viruses, such as staphylococcus and streptococcus.
So, according to these researches, the benefits of white tea may come from the tea polyphenols. Based on some former researches, tea polyphenols contained in almost every kinds of teas. But the content of tea polyphenols would change due to the fermentation rate of tea, and the temperature during making process. The higher the fermentation rate is, the lower the content of tea polyphenols is. Therefore,black teas which are deeply fermented, contain little amount of tea polyphenols. Meanwhile, the high temperature during the making process would decompose tea polyphenols, that is the reason whygreen teas, which required high temperature to lose the water rapidly for preserving the verdant color, would lost few amount of tea polyphenols.
White tea has the simplest making process:
After picking fresh leaves from tea trees and screening out the unqualified leaves, people put the tea leaves under the sun, and let the tea leaves to wilt naturally. Therefore, without the high temperature, and deep fermentation during the making process, cause white tea contains the largest amount of tea polyphenols among all kinds of teas.
However, the simple making method of white tea also brings some negative effects: Without high temperature and deep fermentation during making process, the pesticide and herbicide left on tea leaves will not be decomposed into simple compound. So, white tea may has the highest pesticide and herbicide residues among all kinds of teas.
