Synopsis

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

Notopterygium (commonly referred to as Qiang Huo in Traditional Chinese Medicine, TCM) is primarily used based on traditional practices rather than robust scientific validation for the treatment or support of "Cough (damp)," a term which refers to coughs associated with internal dampness or phlegm as conceptualized in TCM. In classic Chinese herbal texts, Notopterygium is categorized as a herb that dispels wind and dampness, and is more commonly indicated for conditions such as wind-cold-damp bi syndrome (e.g., joint pain, headaches, and body aches). Its historical use for cough is less direct but sometimes included in formulas targeting external wind-cold invasion, which may present with cough.

However, there is little to no modern scientific evidence specifically supporting the efficacy of Notopterygium for coughs associated with dampness. While some laboratory studies have noted anti-inflammatory and analgesic properties in Notopterygium extracts, these findings have not been directly correlated to cough relief or the resolution of "dampness" in the respiratory tract. Therefore, its use for cough (damp) remains primarily grounded in traditional usage, with a low evidence rating due to the lack of direct clinical or pharmacological support for this indication.
