What is Black Tea?

Black tea is the most popular tea in the world. It is the tea most widely used in making iced tea and English tea. During the fermented process, black tea formed more active ingredients and theaflavins. They contain high amounts of Vitamin C, along with calcium, potassium, magnesium, iron, zinc, sodium, copper, manganese, and fluoride. They also have more anti-oxidants than green tea, and are anti-viral, anti-spasmodic and anti-allergic. In addition to all of these health benefits, black teas are also less astringent and have a mellower flavor than green or black teas. Perfect for drinking throughout the day, and also suitable for all ages.

What is Black Tea Polyphenols?

Tea polyphenols have been demonstrated as chemopreventive agents in a number of experimental models. However, less is known about the mechanism of chemoprevention by black tea compared with that of green tea. Some beneficial properties of theaflavins, the black tea polyphenols, were investigated in the present study. Theaflavins showed inhibitory effects on H₂O₂- and tert-butyl hydroperoxide (tBuOOH)-induced cytotoxicity (evaluated by tetrazolium bromide reduction), cellular oxidative stress (detected by oxidation of 2‘, 7‘-dichlorofluorescin), and DNA damage (measured by amount of 8-OHdG and comet assay) in rat normal liver epithelium cell RL-34 cell lines. In addition, theaflavins also exhibited suppression of cytochrome P450 1A1 induced by omeprazole in the human hepatoma HepG2 cell line. Furthermore, when HepG2 cells were pretreated with omeprazole to induce CYP1A1, then exposed to benzo[a]pyrene (B[a]P), DNA damage was observed using the comet assay. However, theaflavins could inhibit this DNA damage. These results indicated that theaflavins could prevent cellular DNA damage by inhibiting oxidative stress and suppressing cytochrome P450 1A1 in cell cultures.
