Product Description Black tea is a kind of fully fermented tea refined from fresh tea leaves through a series of processes such as withering, rolling (cutting), fermentation, drying and so on. During the processing of black tea, a chemical reaction centered on the enzymatic oxidation of tea polyphenols occurs, which leads to major changes in the composition of fresh leaves. Tea polyphenols are reduced by more than 90%, and new chemicals such as theaflavins and thearubicins are produced. Black tea has strong antibacterial ability, and gargle with black tea water can prevent colds caused by filtering viruses, tooth decay and food poisoning, reduce blood sugar levels and high blood pressure.
