医学科学家的研究成果表明，茶叶中的儿茶素具有抑制流感病毒活性的作用，坚持用茶水漱口可有效地预防流感。 流感主要是病毒附着在鼻子和嗓子中突起的粘膜细胞上，并不断增殖而致病的。经常用茶水漱口，儿茶素就能够覆盖在突起的粘膜细胞上，防止流感病毒和粘膜结合，并杀死病 Research results of medical scientists show that catechins in tea have the effect of inhibiting the activity of influenza virus, insisting that gargle with tea water can effectively prevent influenza. Flu is mainly attached to the virus in the nose and throat protruding mucosal cells, and continue to proliferate and pathogenic. Often gargle with tea, catechin can cover the protruding mucosal cells, to prevent the influenza virus and mucosal binding, and kill the disease
