1. Overview

Pí Pá Yè (枇杷叶) is the dried leaf of Eriobotrya japonica, known in English as loquat leaf. It belongs to the category of Herbs that stop coughing and calm wheezing in the Chinese Materia Medica and is one of the most useful herbs in Chinese herbal medicine for Lung Heat cough, dry cough with sticky phlegm, and Stomach Heat with nausea or hiccup. It is the principal ingredient of the well-known patent preparation Pi Pa Gao (Loquat syrup).

I prescribe Pí Pá Yè 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.

1. Transforms Phlegm and descends Lung Qi to stop cough
2. Harmonises the Stomach and stops vomiting and hiccup

4. Modern research

Loquat leaf contains triterpene acids (ursolic acid, oleanolic acid, tormentic acid), sesquiterpene glycosides, flavonoids and small amounts of amygdalin (mainly in the seed, less in the leaf). Studies report antitussive, expectorant, anti-inflammatory, hypoglycaemic and antiviral activity. Ursolic acid has been investigated for hepatoprotective and metabolic effects. The leaf should be brushed clean of fine hairs before use, as the hairs can irritate the throat.

5. Cautions and contraindications

Use with caution in cold-pattern cough with clear watery sputum and a pale tongue, where the cool nature may aggravate the picture. The herb should be processed (brushed and honey-fried for cough, or used raw for stomach actions) according to the intended use.

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.
