Synopsis

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

Green tea (Camellia sinensis) has been traditionally used in various cultures, particularly in East Asia, as a home remedy for soothing sore throats and alleviating cough symptoms. The warm liquid can provide temporary relief for throat irritation, which may help reduce coughing. In traditional Chinese medicine, green tea is sometimes included as part of herbal blends intended to support respiratory health and relieve mild coughs, though it is not considered a primary treatment.

From a scientific perspective, green tea contains polyphenols, particularly catechins, which have demonstrated mild antimicrobial and anti-inflammatory properties in laboratory studies. Some limited in vitro research suggests that green tea catechins might inhibit the growth of certain bacteria and viruses that can cause respiratory tract infections. However, there is a lack of robust clinical trials specifically evaluating green tea’s efficacy for treating or alleviating cough in humans. The evidence for its use is therefore largely anecdotal and traditional, with only weak scientific support from indirect mechanisms (such as throat soothing or general immune support). Overall, while green tea may provide comfort during a cough due to its warmth and mild astringency, its use for this purpose is based more on tradition than on strong scientific validation.
