Botanical Description
Peucedanum praeruptorum is a perennial herb in the Apiaceae family, native to central and southern China, where it grows on grassy mountain slopes and at the edges of forests. The plant grows 60-100 cm tall from a stout, cylindrical, somewhat conical taproot 4-15 cm long with a knobby crown bearing the remains of leaf bases. The stem is erect, finely ridged, and branched in the upper portion. The basal and lower stem leaves are large, triangular-ovate in outline, and two-to-three times ternately or pinnately compound, with serrate, ovate to lanceolate leaflets. Small white flowers are borne in compound umbels 4-8 cm across in summer, followed by ovoid, slightly winged schizocarp fruits. In TCM, the dried root (Qian Hu) is used as a bitter, acrid, slightly cold herb that disperses wind-heat, descends qi, and resolves phlegm in cough disorders.

Cultural & Historical Context
Traditional Chinese Uses
Qian Hu (hogfennel root) is a cool, bitter, pungent herb with a dual action on the Lungs: it redirects rebellious Lung Qi downward to stop cough and wheezing, while also transforming Phlegm-Heat. It is appropriate for coughs accompanied by yellow, thick sputum and chest tightness, as well as for early stages of Wind-Heat invasion where these Lung symptoms are present. It pairs well with other Phlegm-clearing and Wind-Heat-dispersing herbs.
