1. Overview

Chuān Bèi Mǔ (川贝母) — Fritillaria cirrhosa / thunbergii — is known in English as Fritillary bulb / Sichuan fritillary. It belongs to the category of Herbs that stop coughing and wheezing in the Chinese Materia Medica and is used in Chinese herbal medicine as a component of classical herbal formulas and tailored prescriptions.

I prescribe Chuān Bèi Mǔ as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan. Herbs are always combined with other herbs selected to match the patient’s individual TCM pattern. Online consultations are available for patients who cannot attend my clinic in person.

See the full Chinese herbal medicine formula directory for detailed information on all 70 classical formulas.

5. Modern research

Fritillaria cirrhosa (Chuan Bei Mu) is the most important herb for Phlegm-Heat cough and one of the most commercially valuable Chinese medicinal herbs, partly due to limited natural supply. Key bioactive constituents include isosteroidal alkaloids (peimisine, imperialine, sipeimine) and steroidal saponins. Research confirms significant antitussive effects (imperialine inhibits the cough reflex centrally), expectorant properties, bronchodilatory effects, anti-inflammatory activity and anti-tumour properties. The alkaloids have specific activity reducing mucus viscosity, making sputum easier to expectorate. Chuan Bei Mu is frequently combined with Zhi Mu (the classical pair Er Mu San) for dry cough from Lung Yin deficiency.

6. Cautions and contraindications

Do not confuse with Zhe Bei Mu (Fritillaria thunbergii) — Zhe Bei Mu is bitter and cold and more appropriate for excess Phlegm-Heat; Chuan Bei Mu is sweeter and gentler, more appropriate for chronic dry cough from deficiency. Both are called Bei Mu. Contraindicated with Wu Tou (Aconite) — a classical incompatibility. Expensive and sometimes adulterated — source from reputable suppliers.

Important: Chinese herbs should always be prescribed by a fully qualified herbalist who is a member of the Register of Chinese Herbal Medicine (RCHM). Never self-prescribe Chinese herbs without professional guidance. Dr (TCM) Attilio D’Alberto is a member of the RCHM with over 25 years of clinical experience.
