<p>Green tea components, such as catechins have been reported to provide several benefits including anti-oxidative, anti-viral/bacterial, and anti-inflammatory effects in vitro and in vivo. Catechins effectively inhibited the adsorption and replication of the influenza virus. Additionally, green tea contains theanine and vitamin C, which enhance the immunity against viral/bacterial infections. Based on these, green tea is hypothesized to have potential benefits in the prevention of influenza and other respiratory tract infections in the clinical setting. However, its specific effects in patients remain unclear. To determine the clinical significance of green tea in the prevention of respiratory tract infections, we conducted an observational study and eight interventional studies. Based on the results of three studies, consuming or gargling green tea or its components significantly aided in the prevention of influenza. Meanwhile, one study showed that green tea successfully prevented common colds. Catechin inhalation was also reported to decrease the bacterial load of methicillin-resistant Staphylococcus aureus in the sputum. Although the anti-viral/anti-bacterial effects of green tea components have been demonstrated in experimental studies, the clinical evidence remains limited. Further studies are required to confirm the clinical efficacy of green tea and its components in preventing respiratory tract infections.</p>
