Che Qian Zi (Plantain Seed, 车前子): The Ancient Herbal Remedy for Urinary Relief

Introduction

Plantain Seed (车前子), or Plantago asiatica, has been revered in Traditional Chinese Medicine (TCM) for over two millennia. Known for its diuretic and heat‐clearing properties, it’s traditionally used to promote urine flow, alleviate urinary tract pressure, and reduce damp‐heat in the lower burner.

Unlike quick‐acting pharmaceuticals, Plantain Seed works gently to restore balance—supporting long‐term urinary comfort and systemic detoxification.

The History of Plantain Seed in Traditional Chinese Medicine

First recorded in the Shennong Bencao Jing (神农本草经) as a middle‐grade herb, Plantain Seed was prized for its ability to “promote water metabolism and clear heat.” Over centuries it became a staple for addressing:

• Edema & Water Retention: Encouraging fluid excretion
• Damp‐Heat Stranguria: Relieving painful, difficult urination
• Toxin Clearance: Assisting the body’s natural detox pathways
