Codonopsis Root, known as Dang Shen in TCM, is a well-known qi-tonifying herb often described as a gentle alternative to ginseng. It is traditionally used to strengthen the Spleen, support the Lung, improve appetite, reduce fatigue and help the body recover after illness.

3. Natures, flavors and meridian entry

According to TCM, Codonopsis Root has a Sweet flavor and Neutral nature. The Sweet flavor helps nourish and tonify the body, while the Neutral nature makes it balanced and suitable for many qi deficiency patterns when used correctly.

Dang Shen enters the Spleen and Lung meridians. The Spleen is related to digestion, appetite and transformation of food into qi and blood. The Lung is related to breathing, voice strength and protective qi. Therefore, this herb is commonly used when weak digestion, tiredness, shortness of breath, low voice or poor recovery appears after illness.

• Supports the Lung: Used in selected formulas for weak breath, low voice, tired cough or qi deficiency affecting the Lung.
• Helps recovery after illness: Often used in restorative soups or formulas for people who feel weak, tired or slow to regain strength.
• Supports natural resistance: Traditionally used to help the body rebuild vitality and maintain better resilience when the pattern is suitable.
• May support fluids: In some formulas, Dang Shen is used when qi deficiency is accompanied by thirst, dryness or reduced body fluids.
