Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Catechins, a class of flavonoids predominantly found in green tea (Camellia sinensis), have been studied for their potential antiviral properties, including effects against influenza viruses. Several in vitro studies have demonstrated that catechins, particularly epigallocatechin gallate (EGCG), can inhibit the replication of influenza viruses by interfering with viral membrane fusion and viral RNA synthesis. Animal studies have also suggested that catechins may reduce viral titers and ameliorate symptoms of influenza infection. Additionally, a few small human clinical trials and observational studies have shown that regular consumption of catechin-rich green tea may slightly reduce the incidence of influenza infections or shorten illness duration. However, these human studies are limited in size and methodological rigor, and results are not fully consistent. Systematic reviews generally conclude that while there is some evidence supporting a modest antiviral effect, more robust clinical trials are needed to confirm efficacy and to determine appropriate dosing. Therefore, the use of catechins for influenza is supported by preliminary scientific evidence, but its effectiveness is not definitively established, meriting a moderate evidence rating.
