Synopsis

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

Green tea (Camellia sinensis) has a long history of use in traditional medicine, particularly in East Asian cultures, for alleviating symptoms of respiratory discomfort, including dry coughs. In traditional Chinese medicine, green tea is sometimes recommended for its soothing, anti-inflammatory, and mildly expectorant qualities. The warm liquid can help moisten the throat, potentially providing relief from irritation associated with a dry cough. Green tea also contains polyphenols and catechins, such as epigallocatechin gallate (EGCG), which have demonstrated some antimicrobial and anti-inflammatory activities in laboratory studies.

However, direct scientific evidence supporting green tea as an effective treatment for dry cough is limited. Most of the support comes from cultural practices and anecdotal reports rather than rigorous clinical trials. The soothing effect likely comes from drinking a warm, non-irritating liquid rather than any specific pharmacological action of green tea itself. Some laboratory studies suggest that green tea catechins can inhibit the growth of certain bacteria and viruses, potentially reducing the severity or duration of some respiratory tract infections, but these effects have not been specifically studied in the context of dry cough.

In summary, while green tea is traditionally used to soothe dry cough symptoms, scientific validation for its effectiveness in this context is lacking. The evidence base is primarily traditional, and the rating reflects the limited but persistent historical use.
