How much do you know about some Chinese Herbs that can replenish vital energy (Zheng Qi), strengthen the constitution, enhance resistance to illness, and treat patterns of deficiency. These are called tonifying herbs, also known as nourishing herbs or restorative herbs.
Most of these herbs are sweet in taste, with the function of replenishing deficiency and strengthening weakness. They can supplement the body's Qi, Blood, Yin and Yang, and are used to treat deficiency syndromes, including Qi-deficiency, Blood-deficiency, Yin-deficiency, Yang-deficiency, Qi-Blood dual deficiency, and Yin-Yang dual deficiency. Some of these herbs also have additional effects such as clearing heat, dispelling cold, generating fluids, moistening dryness, or astringing loss, and thus treat corresponding conditions.
There are four categories in tonifying herbs:
- Qi-tonifying herbs
- Yang-tonifying herbs
- Yin-tonifying herbs
- Yang-tonifying herbs
Today, I’m going to introduce one of the most commonly used Qi-tonifying herbs, Huang Qi (Radix Astragali).(1) (2)
Huang Qi (Radix Astragali), mainly produced in Inner Mongolia, Shanxi, Heilongjiang, etc. Used raw or honey fried.
Properties
- Sweet, slightly warm
- Spleen and Lung Meridians
Functions:
- Tonifies Qi and raises Yang
- Strengthens the exterior and stabilises the surface (protects against external pathogens)
- Promotes urination and reduces oedema
- Expels toxins and promotes tissue regeneration
Clinical applications:
- Spleen-Stomach Qi deficiency
- Spleen-Qi deficiency with sinking middle Qi: organ prolapse (rectal, uterine, gastric prolapse, etc)
- Lung-Qi deficiency: cough, asthma, shortness of breath
- Qi-deficiency: spontaneous sweating, susceptibility to colds
- Qi-deficiency with oedema and difficulty urination
- Qi-Blood deficiency: anaemia, sallow complexion, numb limbs, chronic ulcers or wounds that fail to heal

Caution:
The dosage of Huang Qi must be carefully considered when prescribing it in any formula. When used in small doses, it can raise blood pressure, whereas in large doses, it can lower blood pressure.

This homemade herbal soup is suitable for individuals with weak Spleen and Stomach functions, such as those experiencing poor appetite, fatigue, oedema, loose stools, pale complexion and mild insomnia. In this formula, Huang Qi helps to tonify Qi and raise Yang, thereby strengthening the Spleen and Stomach.
Tonifying herbs like Huang Qi are important in TCM for restoring strength, boosting resistance to illness, and treating long-term weakness. When used with other gentle Spleen-strengthening herbs in Modified Si Shen Tang, they created a safe daily tonic to improve vitality, especially for people with weak digestion and low energy. Regular but careful use can help maintain health and build resilience.
