What Is Dwarf Lilyturf Tuber?
Dwarf Lilyturf Tuber (Mai Dong, 麦冬) is the small, spindle-shaped tuber of Ophiopogon japonicus — a grass-like plant found throughout East Asia. One of the most important and widely used Yin-nourishing herbs in Traditional Chinese Medicine, Mai Dong is prized for its ability to simultaneously moisten three critical organ systems: the Lung, Stomach, and Heart.
Sweet, slightly bitter, and slightly cold in nature, Dwarf Lilyturf Tuber enters the Lung, Stomach, and Heart channels. Its moistening, fluid-generating nature makes it a premier herb for all conditions of Yin deficiency and internal dryness. In the Lung, it moistens dryness and stops cough. In the Stomach, it generates fluids and clears deficiency heat. In the Heart, it nourishes Heart Yin and clears mild Heart heat to calm restlessness, anxiety, and sleeplessness.
History & Origin
Mai Dong, the tuber of dwarf lilyturf, is a classical Yin-and-fluid tonic recorded for over two millennia, prized for moistening the Lungs, Heart, and Stomach.
Han Dynasty (206 BCE to 220 CE)
Listed in the Shennong Bencao Jing as a superior herb that nourishes Yin and generates fluids.
Tang Dynasty (618 to 907 CE)
Used for dry cough, thirst, and irritability from Yin deficiency.
Song Dynasty (960 to 1279 CE)
Featured in formularies for Lung and Stomach dryness and for calming the spirit.
Ming Dynasty (1368 to 1644 CE)
Li Shizhen's Bencao Gangmu detailed Mai Dong for moistening the Lungs and clearing the Heart; central to Sheng Mai San.
Modern Era
Ophiopogonins and polysaccharides are studied for cardiovascular, immune, and blood-sugar effects.
Traditional Uses
Moistens the Lung & Stops Cough
Nourishes Lung Yin and moistens Lung dryness — used for dry cough, scanty or sticky phlegm, dry throat, and chronic Lung Yin deficiency from prolonged illness or autumn dryness.
Nourishes Stomach Yin & Generates Fluids
Restores depleted Stomach Yin and generates body fluids — used for dry mouth, thirst, nausea, and loss of appetite from Stomach Yin deficiency.
Clears Heart Heat & Calms the Shen
Clears mild Heart Heat and nourishes Heart Yin — used for restlessness, anxiety, irritability, palpitations, and insomnia from Heart Yin deficiency with deficiency heat.
Clears Deficiency Heat
Its slightly cold nature clears the low-grade heat of Yin deficiency — used for afternoon fever, flushing, night sweats, and the five-palm heat of Yin deficiency.
