Plantain Seed (Che Qian Zi): A Cooling Herb for Dampness, Urinary Flow, and Vision Support
Introduction
Plantain Seed, known as Che Qian Zi (车前子) in Traditional Chinese Medicine (TCM), comes from the mature seeds of Plantago asiatica or Plantago depressa. It is valued for its cooling, draining, and Dampness-transforming actions that promote urination, clear Heat, resolve phlegm, and support eye health. With its sweet, slightly cold nature, Che Qian Zi is commonly used to clear Damp-Heat from the lower burner, soothe the urinary system, open the water pathways, and nourish vision.
What Is Plantain Seed?
Plantain plants produce tiny brown seeds that are harvested and dried for medicinal use. In TCM, Che Qian Zi enters the Kidney, Liver, Lung, and Small Intestine meridians. The seeds contain mucilage, aucubin, plantamajoside, and antioxidants that contribute to its ability to drain Dampness, cool Heat, and soothe tissues. Its primary actions include promoting urination to treat edema, clearing Damp-Heat from the urinary tract, brightening the eyes, treating diarrhea from Dampness, and transforming phlegm in the Lungs.
