Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Glehnia littoralis, also known as "bei sha shen" in Traditional Chinese Medicine (TCM), has a long-standing history of use for supporting the respiratory (bronchial) system. In TCM, the root of Glehnia littoralis is traditionally employed to "moisten the lungs," alleviate dry cough, and relieve sore throat. Classical herbal texts and modern TCM practice often recommend it for conditions characterized by dry, irritating coughs, particularly those associated with lung yin deficiency.

While there is a substantial tradition behind its use, scientific validation remains limited. Some pharmacological studies have identified anti-inflammatory, antioxidant, and mild immunomodulatory effects in extracts of Glehnia littoralis. These properties could theoretically support respiratory health, but clinical trials in humans are sparse or lacking. Most of the evidence comes from in vitro or animal studies, which suggest potential benefits but fall short of providing robust, direct support for its efficacy in managing bronchial or respiratory conditions in humans.

In summary, the use of Glehnia littoralis to support the bronchial system is primarily justified by traditional usage and historical precedent rather than strong scientific evidence. The traditional rating is relatively high due to its consistent presence in classical formulas for respiratory care, but the lack of clinical trials prevents a higher evidence rating.
