Bupleurum, particularly the species Bupleurum chinense (Chai Hu), has a long history of use in Traditional Chinese Medicine (TCM). It is commonly included in classic herbal formulas such as Xiao Chai Hu Tang and Chai Hu Gui Zhi Tang, which are sometimes prescribed for respiratory conditions, including symptoms related to lung congestion, such as cough and chest tightness. In TCM theory, Bupleurum is believed to "soothe the Liver," "disperse heat," and "release the exterior," actions thought to indirectly benefit conditions involving congestion or stagnation in the chest. While these traditional uses are well-documented in historical texts and continue in modern practice, the direct application of Bupleurum specifically for lung congestion is not as prominent as for other uses, such as harmonizing or relieving fever. From a scientific standpoint, there is limited evidence supporting Bupleurum’s direct effect on lung congestion. Some preclinical studies suggest anti-inflammatory and immunomodulatory properties, but these are preliminary and not directly linked to clinical improvements in lung congestion. Overall, the primary justification for using Bupleurum for lung congestion is based on traditional knowledge rather than robust scientific validation.
