Cun Dong Ophiopogon Root Tuber

Traditional Use

Primary Actions

• Nourishes yin and generates fluids ... Cun Dong belongs to the Ophiopogon maidong stream used for thirst, dry mouth, and depletion of Lung-Stomach fluids after heat or chronic dryness.
• Moistens the Lung and stops dry cough ... it is chosen for dry throat, scant sputum, and chronic cough patterns in which yin and fluid damage are central.
• Clears Heart irritability ... traditional use extends to restlessness, poor sleep, and vexation when dryness-heat or yin depletion disturbs the Heart.

Secondary Actions

• This page preserves Cun Dong as a larger fleshy selected-tuber lane within the Ophiopogon complex rather than collapsing it into the already separate `liriope-root-tuber` / Shan Mai Dong record.
• The lot distinction matters mainly for authenticity and merchandising ... clinically it still behaves like an Ophiopogon-derived Mai Dong page.

Classic Formulas

• Mai Men Dong Tang ... classic Lung-Stomach dryness formula where maidong moistens, descends, and rebuilds fluids.
• Sheng Mai San ... qi-and-yin restoring formula lineage in which maidong supports fluids and the Heart.
• Sha Shen Mai Dong Tang ... classic dry-Lung pattern formula that highlights the moistening side of maidong.

Classical References

• Traditional herbology describes maidong as sweet, slightly bitter, and slightly cold, entering the Heart, Lung, and Stomach to nourish yin, generate fluids, moisten dryness, and relieve vexation.
• This record keeps the Ophiopogon source explicit so the repo's Liriope-derived Shan Mai Dong page remains a meaningful parallel rather than a duplicate.
