Synopsis

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

Bupleurum is a traditional herb widely used in Chinese medicine, especially in the context of complex herbal formulas. In Traditional Chinese Medicine (TCM), Bupleurum (柴胡, Chai Hu) is not typically used as a direct remedy for dry cough but is included in formulas aimed at "harmonizing" or treating conditions attributed to "Liver Qi stagnation" or "exterior syndromes." Its use for cough is mostly indirect and based on traditional practices rather than scientific validation. For example, Bupleurum is a key ingredient in formulas like Xiao Chai Hu Tang, which may be prescribed for respiratory symptoms associated with colds or flu, sometimes including cough. However, there is little to no direct evidence from controlled clinical trials supporting Bupleurum as an effective monotherapy specifically for dry cough. Most modern research on Bupleurum focuses on its anti-inflammatory, hepatoprotective, and immunomodulatory properties, not on cough relief. Thus, while its use for cough (dry) is rooted in tradition, there is weak and indirect support for this specific indication, and it is rarely used alone for cough in either traditional or modern medical practice.
