Peucedanum praeruptorum
TCM herb that descends qi and dispels wind-heat phlegm.
Qian Hu (Peucedanum praeruptorum) is a traditional Chinese medicinal herb used to descend lung qi and dispel wind-heat phlegm. It is employed as an expectorant and antipyretic for conditions such as cough with thick yellow phlegm and chest fullness. Key active compounds include praeruptorins A and B, coumarins, decursinol, and nodakenin.
Praeruptorins A and B, the primary coumarins in Qian Hu, exhibit bronchodilatory effects by inhibiting phosphodiesterase (PDE) and increasing intracellular cAMP, leading to relaxation of bronchial smooth muscle. Additionally, they demonstrate anti-inflammatory activity through suppression of NF-κB pathway, reducing cytokine release. The expectorant action is attributed to increased mucociliary clearance and reduced mucus viscosity. These mechanisms collectively support its traditional use for cough with thick phlegm and wind-heat patterns.
