Dāng Guī (Angelica)
🩸- Primary Action Tonifies Blood and regulates the menses.
- Secondary Action Invigorates Blood and relieves pain.
- Character Warm, Sweet, Acrid. Acts on HT, LV, SP.
Huáng Qí (Astragalus)
☀️- Primary Action Powerfully tonifies Qi and raises Yang.
- Secondary Action Tonifies Wei Qi and promotes tissue growth.
- Character Slightly Warm, Sweet. Acts on LU, SP.
The 5:1 Ratio Principle
In the famous formula Dāng Guī Bǔ Xuè Tāng, the ratio is traditionally 5 parts Huáng Qí to 1 part Dāng Guī.
The Logic: According to Chinese medicine, "Qi is the commander of Blood." To quickly replenish Blood lost from hemorrhage or severe exhaustion, one must massively boost the Qi (the engine) so that it can "capture" and "generate" the Blood substance.
Relative Action Intensity
The functional balance for rapid recovery.
Pharmacology and Kinetics
Synergy in tissue repair and hematopoiesis.

Formula Architecture
The "Blood-Generating" Lineage.
| Formula Name | Pair's Role | Main Use |
|---|---|---|
| Dāng Guī Bǔ Xuè Tāng | Chief & Deputy | Acute rescue of Blood following extreme Qi exhaustion or heavy blood loss. |
| Guī Pí Tāng | Primary Core | Chronic depletion affecting Heart & Spleen; addresses anxiety and insomnia. |
| Bā Zhèn Tāng | Supporting Bridge | General constitutional tonification for concurrent Qi and Blood deficiency. |
Clinical Insight
This pair represents the Blood Generating Dynamic. While Dāng Guī provides the material, Huáng Qí provides the warmth and catalytic energy required to transform that material into functional Blood. Also Huáng Qí is "floating" (moves to the exterior/skin), while Dāng Guī is "sinking" (moves to the interior/blood). This contrast is what makes the pair so effective for "Non-healing Wounds"—Huáng Qí pushes the energy to the surface to close the wound, while Dāng Guī provides the blood to knit the tissue back together.
