"Influenza prevention measures through oral care"
1) Black tea polyphenols inhibit the growth of periodontal bacteria
2) Periodontal bacteria promote influenza virus infection
3) Black tea polyphenol suppresses periodontal bacteria and at the same time suppresses influenza virus
It was found that black tea, which has the effect of suppressing the action of proteolytic enzymes involved in infection, is even more useful in preventing influenza infection!
