Synopsis

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

Green tea (Camellia sinensis) has been traditionally consumed in many Asian cultures as a remedy for colds and fevers. Historical records from traditional Chinese and Japanese medicine suggest that green tea was often recommended for its perceived cooling and detoxifying effects, making it a popular beverage during fevers or respiratory illnesses. The polyphenols and catechins in green tea, particularly epigallocatechin gallate (EGCG), have demonstrated mild antimicrobial and antiviral properties in laboratory studies, which could theoretically provide some benefit against cold viruses. Additionally, green tea contains moderate amounts of caffeine and the amino acid L-theanine, which may have gentle immune-modulating and soothing effects.

However, direct scientific evidence supporting the use of green tea specifically for treating colds with fever is limited. Most clinical studies focus on general immune support or prevention, rather than acute treatment of colds or fever. Some small studies suggest green tea gargles may reduce upper respiratory infections in certain populations, but these findings are not robust enough to warrant high confidence. Thus, while green tea is traditionally used to support colds and fevers and has plausible mechanisms that could be beneficial, strong scientific validation for this use is lacking, leading to a modest evidence score.
