Huang Qi Jian Zhong Tang (黄芪建中汤): Astragalus Build-the-Middle Decoction for Qi Deficiency and Abdominal Pain
Learn about Huang Qi Jian Zhong Tang, Zhang Zhongjing's classic formula that tonifies Qi, warms the middle, and relieves chronic abdominal pain — the enhanced version of Xiao Jian Zhong Tang with added Astragalus for deeper constitutional support.
What Is Huang Qi Jian Zhong Tang?
Huang Qi Jian Zhong Tang (黄芪建中汤), the “Astragalus Build-the-Middle Decoction,” is a classical formula created by Zhang Zhongjing around 220 AD, recorded in the Jin Gui Yao Lue (Essentials from the Golden Cabinet). It is an enhanced version of the famous Xiao Jian Zhong Tang (Minor Build-the-Middle Decoction) with the addition of Huang Qi (Astragalus) for stronger Qi tonification.
The name “Jian Zhong” (建中) means “to build the middle” — referring to the formula’s primary action of strengthening the Spleen and Stomach, the Middle Jiao organs responsible for producing all Qi and Blood in the body.
Formula Composition
| Herb | Pinyin | Dosage | Role |
|---|---|---|---|
| Astragalus | Huang Qi | 15g | Chief — Tonifies Qi, lifts Yang, strengthens defense |
| Cinnamon twig | Gui Zhi | 9g | Deputy — Warms meridians, promotes circulation |
| White peony root | Bai Shao | 18g | Deputy — Nourishes blood, relieves spasms and pain |
| Maltose sugar | Yi Tang | 30g | Assistant — Sweet tonifies, nourishes middle, relieves pain |
| Fresh ginger | Sheng Jiang | 9g | Assistant — Warms middle, harmonizes Stomach |
| Jujube | Da Zao | 6 pcs | Assistant — Nourishes blood, harmonizes |
| Honey-fried licorice | Zhi Gan Cao | 6g | Envoy — Harmonizes formula, tonifies Spleen |
Formula Design
The architecture follows a “warm, sweet, build” strategy:
- Gui Zhi + Bai Shao (1:2 ratio): Gui Zhi warms and moves; Bai Shao nourishes and restrains. The 2:1 Bai Shao dominance emphasizes nourishment and pain relief over sweating.
- Huang Qi: The key addition — provides powerful Qi tonification that the original Xiao Jian Zhong Tang lacks.
- Yi Tang (Maltose): The “builder” — its sweet, nourishing nature literally feeds and strengthens the Middle Jiao.
- Sheng Jiang + Da Zao + Zhi Gan Cao: The classic harmonizing trio that supports digestion.

FAQ
How is Huang Qi Jian Zhong Tang different from Xiao Jian Zhong Tang?
Huang Qi Jian Zhong Tang is Xiao Jian Zhong Tang with the addition of Huang Qi (Astragalus). Xiao Jian Zhong Tang warms the middle and relieves abdominal pain, but Huang Qi Jian Zhong Tang adds stronger Qi tonification. Use Huang Qi Jian Zhong Tang when there is more pronounced Qi deficiency — fatigue, shortness of breath, spontaneous sweating — alongside the abdominal pain and cold signs. Think of it as the stronger version for weaker patients.
What type of abdominal pain does this formula treat?
This formula treats chronic abdominal pain that feels better with warmth and pressure, worse with cold and fatigue. The pain is typically dull and aching rather than sharp. It is associated with Spleen-Stomach Qi and Yang deficiency. The patient is often thin, frail, easily fatigued, and runs cold. This pattern is common in chronic gastritis, gastric ulcers, and functional dyspepsia.
