Asparagus Tuber (Tian Men Dong): A Cooling Herb for Yin, Lungs, and Moisture

Introduction

Asparagus tuber, known as Tian Men Dong (天门冬) in Traditional Chinese Medicine (TCM), is a treasured yin tonic valued for its rich ability to nourish fluids, moisten dryness, and clear internal heat. With its sweet, slightly bitter taste and cooling energy, Tian Men Dong is especially used to soothe dry cough, support Lung and Kidney yin, and alleviate symptoms of internal heat or dryness. It’s a gentle, moistening herb that brings comfort to those depleted by stress, illness, or heat.

What Is Asparagus Tuber?

Tian Men Dong is the tuberous root of Asparagus cochinchinensis, a perennial climbing plant native to East Asia. In TCM, it is classified as sweet, bitter, and very cold in nature. It enters the Lung and Kidney meridians. Traditionally, asparagus tuber is used to nourish yin, generate fluids, clear Lung heat, and relieve coughs or throat irritation. Its potent moistening qualities make it ideal for individuals with yin deficiency, especially those with lingering heat or dryness from chronic illness.
