  • The colder seasons are upon us, and that means so many wonderful things: falling leaves, cozy sweaters, crackling fireplaces, and the holidays. But, unfortunately, it also means flu season.


    When your body begins showing signs of a nasty cold, like sneezing or congestion1, or a whole body flu, like chills and fatigue2, you might be inclined to hurry to the drugstore or your medicine cabinet to take over-the-counter meds—which may or may not work. But too often we forget about nature’s remedies for fighting the flu.


    Turns out, sipping3 a hot cup of tea is not only comforting while you're feeling under the weather, but according to research, it's chock-full of benefits to help you combat this season's biggest sickness.


    According to research published in the Proceedings4 of the National Academy of Sciences, drinking black tea is a major immune booster. The study, out of Brigham and Women's Hospital in Boston and Harvard Medical School, found that people who drank five cups of black tea a day for two weeks saw their immune system T cells pumping out 10 times more cold and flu virus-fighting interferon.

    美国国家科学院院刊》(Proceedings of the National Academy of Sciences)有研究显示,红茶是提升免疫力的一大法宝。波士顿布列根和妇女医院(Brigham and Women's Hospital)以及哈佛医学院合作试验表明,每天喝五杯红茶,并坚持两周的人免疫系统内的T细胞能够产生十倍多的抗流感病毒干扰素。

    “We worked out the molecular5 aspects of this tea component6 in the test tube and then tested it on a small number of people to see if it actually worked in human beings,” explained Jack7 F. Bukowski, MD, one of the study's researchers. According to Dr. Bukowski, the results are proof that five cups of tea a day can enhance the body's disease defenses. (Check out these other incredible benefits of black tea.)


    Green tea is another noteworthy flu-fighter thanks to its antioxidant quercetin, as well as an amino acid called L-theanine. Various studies have shown that quercetin acts as a potent8 antiviral agent, hindering viral replication of many respiratory viruses, including influenza9 virus. One study, published in the Journal of Medicinal Food found quercetin to inhibit10 the replication of a common cold virus in its initial stage of infection.

    绿茶因其含有抗氧化物质槲皮素和氨基酸茶氨酸,也能抵抗流感。多项实验表明,茶氨酸是抗病毒的潜在因素,能阻止很多呼吸道病毒复制,比如流感病毒。《药用食材期刊》(Journal of Medicinal Food )做过实验,发现茶氨酸可以在感冒病毒感染初期抑制病毒复制。

    A study completed by researchers at University of Florida and the Nutritional11 Science Research Institute and published in the Journal of the American College of Nutrition found that L-theanine and decaffeinated green tea catechins are capable of boosting the body’s immune system. The results suggest that green tea can decrease the incidence and duration of cold and flu symptoms.

    佛罗里达大学和营养科学研究院(Nutritional Science Research Institute)合作进行了一项实验,结果发表在《美国营养学院期刊》上。实验表明,茶氨酸和去咖啡因的绿茶儿茶酚都能提高人体免疫力。绿茶能降低感冒和流感症状发生的可能性,也能缩短症状周期。

    “With this study, we were able to show that ingestion of a specific combination of decaffeinated tea polyphenols standardized12 to 45 percent EGCg and L-theanine, would enhance systemic immunity13, and prevent cold and flu symptoms in healthy individuals. This is a significant finding,” said lead study author Susan S. Percival, PhD.


    The benefits of tea have long been accounted for, but it is easy to forget that a soothing14 cup does more than just satisfy you—it can prevent against pesky, and sometimes life-threatening, viruses like the flu.
