Description
Radix Ophiopogonis / Ophiopogon Japonicus
Mai Dong · (麦冬)
Botanical Name : Ophiopogon japonicus
Category : Yin Tonic
Slightly cold in nature. Sweet and bitter in taste. It enters the heart, lung and stomach meridians.
Chinese medicine identifies three distinct patterns that Mai Dong addresses: Lung Yin dryness with sticky phlegm, Heart Yin depletion with night-time restlessness, and Stomach Yin weakness with unquenchable thirst. About 15% of people fit the Yin Deficient body type, and most who benefit from mai dong sit somewhere across these three overlapping patterns. Simmered with pear, lily bulb, and rock sugar, mai dong tea may help moisten the lungs and quiet the mind over days of consistent use.
Nourishes Heart and Lung Yin, moistens dryness, calms the mind. Used for dry cough and insomnia.
TCM Properties
Heart, Lung, and Stomach Yin Depletion(心肺胃阴虚)
Heart, Lung, and Stomach Yin Depletion develops when three specific drains combine: prolonged fever that evaporates Lung fluids, chronic emotional stress that burns Heart Yin, and irregular eating habits that exhaust Stomach moisture. Mai dongOphiopogon is one of the few single herbs that reaches all three organs, which is why it anchors classical formulas for stress-related insomnia and post-illness dry cough alike. The pattern is functional rather than structural, and may respond to consistent nourishing food over weeks of daily use.
Health Benefits
Nourishes Lung Yin and moistens dryness
Ophiopogon’s cool, moistening nature directly replenishes the fluids that the lungs need to function smoothly. For dry cough with sticky, hard-to-expectorate phlegm, it softens the phlegm and moistens the lung tissue. It is a key ingredient in Mai Men Dong Tang, the classical formula for lung dryness.
Nourishes Heart Yin and clears irritability
When heart yin is deficient, a specific pattern emerges: irritability, restlessness, and a feeling of internal heat that is worse at night. Mai dong’s cooling, moistening nature replenishes the heart yin that anchors this heat, making it useful for stress-related insomnia with palpitations.
Nourishes Stomach Yin and generates fluids
For the dry mouth, thirst, and reduced appetite that accompany stomach yin deficiency, Ophiopogon generates fluids and restores the stomach’s moist environment. This pattern often appears after fever, chronic stress, or in older adults.
Moistens the intestines for dry constipation
When yin deficiency dries out the intestines, stool becomes hard and difficult. Ophiopogon’s moistening nature helps lubricate the intestines, providing gentle relief for deficiency-type constipation without the harshness of stimulant laxatives.
Commonly Used For
· People with dry cough, sticky phlegm, and dry throat
TCM Interpretation: Lung yin deficiency produces a dry, irritating cough where any phlegm is sticky and difficult to clear. Ophiopogon’s moistening action softens the phlegm and soothes the lung tissue.
Why Ophiopogon (Mai Dong) Helps: Simmered with pear and rock sugar, Ophiopogon creates a traditional lung-moistening remedy that is both effective and palatable. It works gradually over days of consistent use.
· Those with night-time irritability, dry mouth, and restless sleep
TCM Interpretation: Heart yin deficiency creates a pattern where the internal heat surfaces at night, disrupting sleep and causing dry mouth. Ophiopogon replenishes the yin that would normally keep this heat in check.
Why Ophiopogon (Mai Dong) Helps: A cup of Ophiopogon tea in the evening provides gentle, cooling nourishment. For stronger effect, it is combined with sour jujube seed (suan zao ren) in classical sleep formulas.

Dietary Advice
Soak Ophiopogong in warm water for 30 minutes before use. Simmer with pear, lily bulb, and rock sugar for a lung-moistening dessert soup, or brew alone as a gentle tea. For heart yin support, combine with red dates and lotus seeds. Avoid taking Ophiopogon if you have spleen deficiency with loose stools or damp phlegm, as its cool, moistening nature may worsen these conditions.
