Synopsis

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

Tea, particularly mixed herbal teas, has been traditionally used across many cultures as a remedy to support the body during colds. The use is largely based on historical and anecdotal evidence rather than robust scientific validation. Common ingredients in mixed teas for colds include herbs such as ginger, chamomile, peppermint, elderflower, and echinacea, each with a history of folk use for soothing symptoms like sore throat, congestion, or cough. Black and green teas, which contain polyphenols and catechins, have also been consumed for their purported immune-supporting properties.

Some laboratory studies suggest that certain tea compounds (like catechins in green tea) have mild antiviral effects in vitro, but clinical evidence in humans is limited and inconsistent. The primary benefit of mixed teas for colds is likely due to the soothing effect of warm fluids, temporary relief of symptoms, and hydration rather than direct antiviral action. Thus, while tea is a comforting traditional remedy, the scientific evidence supporting its use specifically as an antiviral treatment for colds remains modest.
