Historical Background of Qian Hu
Qian Hu has been documented for over a thousand years, with references in Shen Nong Ben Cao Jing and Ben Cao Gang Mu. Traditionally cultivated in the Sichuan region of China, the root was regarded as essential for treating lung conditions brought on by seasonal changes, wind invasions, and phlegm-heat congestion.
In classical formulas, it is often paired with herbs like Zhi Ke (Bitter Orange Peel) or Jie Geng (Platycodon Root) to guide phlegm downward and open the chest.
