1. Overview

Zhè Bèi Mǔ (浙贝母) is the bulb of Fritillaria thunbergii, the Zhejiang fritillary. It belongs to the category of Cool-transforming Phlegm-Heat herbs in the Chinese Materia Medica. Although closely related to Chuān Bèi Mǔ (Fritillaria cirrhosa), Zhè Bèi Mǔ is stronger at clearing Phlegm-Heat and softening hardness, while Chuān Bèi Mǔ is preferred for Yin-deficient dry cough.

I prescribe Zhè Bèi Mǔ 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. Clears Phlegm-Heat and stops cough
2. Resolves toxicity and reduces nodules and abscesses
3. Softens hardness

Indications

1. Productive cough with thick yellow phlegm from Phlegm-Heat
2. Acute bronchitis and chest infection with heat features
3. Scrofula, lymphadenopathy and goitre from Phlegm-Fire constraint
4. Breast abscess and breast nodules with heat signs
5. Carbuncles and skin sores from heat-toxin

4. Modern research

Fritillaria thunbergii contains isosteroidal alkaloids (peimine, peiminine), saponins and polysaccharides. Studies report antitussive, expectorant, anti-inflammatory and antitumour activity. Peimine has mild hypotensive effects in animal models.

5. Incompatibilities

The classical Ming-dynasty texts Shi Ba Fan (Eighteen Antagonisms) and Shi Jiu Wei (Nineteen Mutual Inhibitions) record herb pairs that should not be combined. Modern practitioners treat these as strong cautions rather than absolute contraindications — classical training avoids the combinations except in carefully supervised low-dose protocols.

Zhè Bèi Mǔ (浙贝母) Zhejiang Fritillaria should not normally be combined with:

• Fu Zi — per the Shi Ba Fan
• Chuan Wu — per the Shi Ba Fan
• Cao Wu — per the Shi Ba Fan

6. Cautions and contraindications

Contraindicated in cough from cold-phlegm or Yin-deficient dry cough — use Chuān Bèi Mǔ instead. Traditionally considered incompatible with Fù Zǐ and Wū Tóu (the “eighteen incompatibilities”).

Pattern contraindications

Contraindicated in Cold patterns and Spleen Yang deficiency. Some (e.g. Gua Lou family) have mild laxative effect — caution in chronic diarrhoea.

Modern drug interactions

Generally well tolerated. Tell your GP if on regular medication.

Important: Chinese herbs should always be prescribed by a fully qualified herbalist who is a member of the Register of Chinese Herbal Medicine (RCHM).

7. Treatment at my clinic

I prescribe Zhè Bèi Mǔ as part of tailored herbal formulas for chest infections with stubborn yellow phlegm, recurrent bronchitis, thyroid nodules with heat features and breast nodules within a Phlegm-Fire pattern. 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.
