3. Natures, flavors and meridian entry

According to TCM, Astragalus Root has a Sweet flavor and a slightly Warm nature. The Sweet flavor helps tonify qi and nourish the body, while the slightly Warm nature supports yang qi and helps strengthen overall vitality without being overly Hot when used properly.

Huang Qi enters the Spleen and Lung meridians. The Spleen is related to digestion, transformation of nutrients and formation of qi and blood. The Lung is related to breathing, surface defense and protective qi. For this reason, the herb is often used for fatigue, poor appetite, weak digestion, spontaneous sweating and low resistance.

4. Benefits and traditional actions of Astragalus Root in TCM

Astragalus Root is one of the leading herbs for tonifying qi. Common traditional actions include:

• Tonifies qi and strengthens resistance: Supports people who feel tired, weak, easily exhausted or slow to recover.
• Secures the exterior: Often used for people who catch colds easily or sweat without exertion due to qi deficiency.
• Promotes urination and reduces swelling: Used in selected formulas for edema or low urination related to weak Spleen qi.
• Supports tissue repair: Raw Huang Qi is traditionally used to support slow-healing wounds and recovery when the pattern is suitable.
• Supports metabolic balance: Modern herbal discussions often mention its role in supporting healthy blood pressure, blood sugar and lipid metabolism, but it should not replace medical treatment.

This herb is a tonic, not a quick stimulant. It works best when the body pattern matches qi deficiency.

5. How to use Huang Qi and suggested dosage

Astragalus Root can be used in several common ways:

• Decoction: Use 9–30 g per day, often combined with Atractylodes, Codonopsis Root or Licorice Root.
• Cooking: Add to chicken soup, pork soup or porridge to support qi, strength and recovery after illness.
• Herbal wine: Sometimes combined with Dong Quai or ginseng in strengthening formulas, but alcohol preparations are not suitable for everyone.

New users should start with a moderate dose and observe the body response. Long-term use may be suitable in qi deficiency, but it should be avoided when there are strong heat signs or acute illness.
