Bergenin Classic Formulas — Natural Herb Library

Primary Actions

Relieves cough and facilitates phlegm resolution - modern Chinese use centers on chronic bronchitis, persistent cough, and phlegm-laden respiratory irritation, especially in tablet form.
Moderates inflammatory irritation in the Lung - the compound-level record reflects the long use of bergenin-containing source herbs for chronic inflamed airway states rather than acute exterior pathogens.
Bridges source-herb tradition and standardized manufacture - Yan Bai Cai Su is valued because it converts the cough-relieving activity of the Yan Bai Cai lineage into a measured single-ingredient or compound pharmaceutical.
Has broader anti-inflammatory extension beyond the Lung - modern work has expanded interest into intestinal, hepatic, and airway inflammatory models, although these are not classical stand-alone indications for the isolated compound.

Yan Bai Cai Su Pian (岩白菜素片) - standardized bergenin tablet used in modern Chinese respiratory practice for cough and chronic bronchitic irritation.
Fu Fang Yan Bai Cai Su Pian (复方岩白菜素片) - compound bergenin tablet widely used for chronic bronchitis, reflecting the modern pharmaceutical rather than ancient decoction use of this record.

IMPORT NOTE: The source spreadsheet imported the isolated compound Yan Bai Cai Su rather than the parent herb Yan Bai Cai. This file is therefore handled like a modern compound-level respiratory record, not a classical single-herb entry.
Chinese herb sources for Yan Bai Cai describe the parent medicinal as sweet and astringent, cool, and entering the Liver, Lung, and Spleen, with cough-relieving and hemostatic actions; bergenin is one of its major active constituents.
Modern Chinese product literature treats bergenin as a principal active ingredient in antitussive and chronic-bronchitis preparations, which explains why this import record appears as a stand-alone substance.
