Have you gargled with tea? Some do in Japan. We believe that tea, especially Japanese green tea, helps prevent from catching a cold. It is reasonable because the tea has a lot of catechin, which has the effect of killing bacteria.
Some schools especially at the tea-production areas encourage their students to gargle with tea during winter. Between classes, after PE class, before school lunch…..the all students gurgle with tea. According to those schools, fewer students catch a cold since they have introduced this system.
Coarse tea has more catechin than high-quality tea. Even tasteless tea made from used tea leaves has enough catechin to work for killing bacteria. Why don’t you try?
