The research results of Professor Tadakatsu Inamura at Showa University in Japan indicate that catechins in tea have an inhibitory effect on the activity of influenza viruses. Persisting in rinsing with tea can effectively prevent influenza, which is mainly caused by the virus adhering to the protruding mucosal cells in the nose and throat and continuously proliferating, leading to disease. Rinse your mouth frequently with tea, as catechins can cover the protruding mucosal cells, preventing the influenza virus from binding to the mucosa and killing the virus. The effect of catechins is like vaccination against influenza virus, which can have a preventive effect.
They said that oolong tea, black tea, and Japanese tea all contain catechins, but green tea has the best effect in preventing influenza. Dilute the concentration of daily green tea to 1/4, and mix the influenza virus into the tea for 5 seconds. The virus loses its ability to infect.
