Asparagus Tuber Whole (Asparagus Cochinchinensis)

Asparagus Tuber Whole (Asparagus cochinchinensis), known in Traditional Chinese Medicine as Tian Men Dong (天门冬), is the thick, fleshy root of a wild asparagus species used to nourish yin, moisten dryness, and clear internal heat, especially from the lungs and kidneys. These whole tubers are carefully dried to retain their dense texture and naturally sweet-bitter taste, making them ideal for use in long-simmered herbal decoctions.

Tian Men Dong is especially valued in TCM for treating dry cough, wheezing, or hoarseness due to lung yin deficiency. It helps to restore moisture to the respiratory tract and ease symptoms like dry throat, sticky or scanty sputum, and chronic dryness-related irritation. It also nourishes kidney yin, making it suitable for use in formulas addressing low back pain, dizziness, night sweats, or wasting and thirsting disorders (such as diabetes) associated with internal heat and fluid depletion.

With its strong moistening properties, Asparagus Tuber is often included in yin-tonifying formulas alongside herbs like Mai Men Dong, Sheng Di Huang, and Xuan Shen to support lung function, replenish body fluids, and gently cool internal heat without being overly cold in nature.

When decocted, Asparagus Tuber Whole yields a thick, slightly sweet infusion that soothes dryness and nourishes deep internal tissues. It is most commonly used in traditional preparations for lung and kidney support, as well as overall yin restoration.

Each batch of Asparagus Tuber Whole (Asparagus cochinchinensis) is carefully harvested and sun-dried to maintain its herbal potency and purity. Whether used in respiratory formulas, yin-nourishing tonics, or chronic dryness conditions, Tian Men Dong offers a gentle, replenishing path to inner moisture and balance.
