Cochinchinese asparagus root · Tian Men Dong
Asparagus cochinchinensis (Lour.) Merr. · Tuberous roots
Name and part used
A slender spiny climber with clustered flat cladodes and red berries; it bears fleshy tuberous roots.
Traditional context
Tian Men Dong is Asparagus cochinchinensis root, distinct from edible asparagus and ornamental Asparagus setaceus. HKBU records autumn-winter tuber harvest; roots form clusters.
Modern evidence
Yin-nourishing and lung-moistening are traditional claims. Ingredient studies do not establish treatment for chronic cough, tuberculosis, or constipation.
Safety
Diarrhea or allergy may occur. Pregnancy, diuretic medicines, or kidney disease warrant professional advice.
Pairing in reference texts
Tian Men Dong appears with Mai Men Dong, Sheng Di, or Sha Shen in yin-nourishing formulas. Historical pairing does not establish safety with modern medicines.

- Harvest tuberous roots in autumn-winter from authenticated cultivation; reject damaged material and distinguish from ornamental Asparagus.
- Remove stems and fine roots, wash soil, and grade tubers for consistent processing.
- HKBU describes blanching or steaming until peeling is possible, then peeling and low-heat drying. This is professional processing only.
- Control moisture and color, pack against humidity, and document peeled form and tested lot.
