A recent medical study indicates that simply drinking a cup of green tea daily could prevent influenza infection, especially for school-aged children. Japanese researchers studied 2,663 students aged 6 to 13 who drink tea daily and found 40 percent were less likely to get the flu. Those who drank up to five cups a day were the least likely to become ill. Even just one cup of green tea per day also had significantly fewer absences due to flu. Researchers concluded that regular consumption of green tea is protective against influenza infections.
Other researchers at the Yonsei University’s Department of Biotechnology at the College of LifeScience and Biotechnology in Seoul, South Korea, tested green tea solutions in variousconcentrations and discovered tea killed the influenza virus on skin. All concentrations were effective against the flu virus, including the one with the lowestconcentration. Skin was exposed to one green tea bag per 120 ml of hot water low concentration and two to three bags per 120 ml to test higher concentrations. Even weak green tea solutionsproved effective. Researchers concluded that using a green tea solution as a hand disinfectant, gargling with tea and drinking tea could be a useful way to prevent transmission of the flu virus.
