Summary

The purpose of this study is to evaluate the effects of catechin extracts containing mask on prevention of influenza infection.

Detailed description

Catechins are the major components of tea flavonoids and are reported to possess physiological activities such as antiviral effects. Recent in-vitro experimental studies have revealed that tea catechin extracts possess the effects on the prevention of influenza infection.
