Ophiopogon Root (Mai Men Dong): A Moistening Herb for Yin, Lungs, and Heart
Introduction
Ophiopogon root, known as Mai Men Dong (麦门冬) in Traditional Chinese Medicine (TCM), is a gentle yet deeply nourishing herb treasured for its ability to moisten dryness, nourish yin, and calm irritability. With a sweet, slightly bitter flavor and cool nature, it is commonly used to soothe dry coughs, nourish the Stomach and Lung yin, and promote restful sleep through Heart yin support. This versatile root is a go-to herb for restoring fluids and easing internal dryness caused by heat, illness, or yin deficiency.
What Is Ophiopogon Root?
Mai Men Dong is the tuberous root of Ophiopogon japonicus, a grass-like plant native to East Asia. In TCM, it is classified as sweet, slightly bitter, and cool in nature. It enters the Heart, Lung, and Stomach meridians. Traditionally, it is used to nourish yin and generate fluids, moisten the lungs, clear heat from the Heart, and relieve irritability or insomnia. Its yin-restorative qualities make it particularly beneficial during recovery from febrile illnesses, or for those with chronic dryness.
