Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to clarify the preventive effects of catechin gargling on the influenza infection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In-vitro experimental studies have revealed that tea catechin extracts induce preventive effects on influenza infection. However, few studies have been conducted on the effects of tea gargling on influenza infection, and the clinical evidence is unclear. Also there have been no studies reported on the gargling effects with tea catechin extracts on the prevention of influenza infection.
