1. Overview

Tài Zǐ Shēn (太子参) is the dried root of Pseudostellaria heterophylla, known in English as Pseudostellaria root, false starwort or "Prince’s ginseng". It belongs to the category of Herbs that tonify Qi and is among the gentlest Qi tonics in the Chinese Materia Medica — markedly milder than Rén Shēn (ginseng), and particularly suited to children, the elderly, post-illness recovery and patients with Qi-and-Yin deficiency in whom warmer tonics would be too heating.

I prescribe Tài Zǐ Shēn as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan.

2. Properties

3. Actions and indications

Principal actions

1. Tonifies Spleen and Lung Qi gently
2. Generates fluids and nourishes Yin

Indications

1. Mild Spleen Qi deficiency with fatigue, poor appetite, loose stools — particularly in children, the elderly, or after febrile illness
2. Lung Qi deficiency with shortness of breath and chronic dry cough
3. Combined Qi-and-Yin deficiency with dry mouth, low-grade thirst and a peeled red tongue
4. Post-viral fatigue when stronger tonics are too warming

4. Modern research

Pseudostellaria root contains polysaccharides, cyclic peptides (heterophyllins), saponins and free amino acids. Pharmacological studies report immunomodulatory, anti-fatigue, anti-stress and antioxidant effects. Compared with Rén Shēn the activity is milder and the side-effect profile is favourable, making it a useful first-line Qi tonic in patients who do not tolerate warmer or stronger tonics.

5. Cautions and contraindications

Generally very well tolerated and considered one of the safest Qi tonics. No significant drug interactions documented. As with all tonifying herbs, use with caution in patients with active exterior pathogenic conditions until the exterior is released.

Important: Chinese herbs should always be prescribed by a fully qualified herbalist who is a member of the Register of Chinese Herbal Medicine (RCHM). Dr (TCM) Attilio D’Alberto is a member of the RCHM with over 25 years of clinical experience.

6. Treatment at my clinic

I prescribe Tài Zǐ Shēn as part of tailored herbal formulas for paediatric recovery after illness, post-viral fatigue, combined Qi-and-Yin deficiency in elderly patients, and chronic dry cough in Lung-Yin-deficient constitutions. Every prescription is individually formulated following a full TCM assessment.

I see patients in person at my clinic in Wokingham, Berkshire. Online Chinese herbal medicine consultations are available.
