Synopsis

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

Stephania root (from species such as Stephania tetrandra and Stephania glabra) has a long history of use in traditional Chinese medicine (TCM) and other Asian herbal practices. In TCM, Stephania root—often referred to as "Fang Ji"—is used to "dispel wind and dampness," alleviate pain, and sometimes to address symptoms such as cough, particularly when associated with dryness or irritation. The traditional rationale is based on its supposed ability to clear heat and remove toxins, which are believed to contribute to dryness and cough in TCM theory.

Despite its historical use, there is limited scientific research specifically evaluating Stephania root for the treatment of dry cough in humans. Most available studies focus on its anti-inflammatory, analgesic, and immunomodulatory properties, with some laboratory and animal model evidence suggesting that certain alkaloids (like tetrandrine) found in Stephania may have effects on airway inflammation or smooth muscle relaxation. However, these findings have not been robustly translated into clinical trials for cough—dry or otherwise.

In summary, the use of Stephania root for dry cough is primarily justified by traditional herbal practices rather than modern scientific evidence. The evidence rating given (2/5) reflects a moderate degree of longstanding traditional use but a lack of strong clinical or pharmacological data supporting its efficacy specifically for dry cough.
