In winter, black tea that warms the body and nourishes the stomach has gained a new function. According to the latest research from Japan's Shibaura University, people who drink more than two cups of black tea per day have a 30% lower chance of being infected by influenza viruses compared to those who don't drink it! Experts believe this may be due to the rich antioxidants in black tea that can enhance human resistance, thus providing effective protection against influenza.

In fact, research on black tea preventing influenza has been conducted before. A study from Japan's Showa University found that not only drinking black tea but also using black tea as a mouthwash can help fight influenza. American scientists particularly recommend brewing black tea in cold water for stronger effects. Cold water allows the beneficial compounds in tea to dissolve slowly without being destroyed. Drinking one cup each in the morning and afternoon can effectively keep influenza from "approaching" you.
