What is Hogfennel Root (Qian Hu)?
Hogfennel Root (qian hu, 前胡), also known as Radix Peucedani, refers to the dry root of Peucedanum praeruptorum Dunn, a perennial herbaceous plant that belongs to the Umbelliferae family.

Bitter and pungent in taste, Qian Hu can cleanse the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. Also, Qian Hu can promote the circulations of qi and body fluids. In particular, Qian Hu targets the Spleen and the Lungs.
