Dahurian Rhododendron Leaf

Traditional Use

Primary Actions

• Relieves cough and transforms phlegm - Man Shan Hong is classically used for cough, dyspnea, and chest oppression with copious phlegm.
• Benefits acute and chronic bronchitic patterns - regional use in northeastern China especially emphasizes productive cough and recurrent bronchial irritation.
• Clears phlegm-heat and eases labored breathing - its bitter, acrid, cooling profile makes it more suitable for obstructive phlegm and heat than for dry deficient cough.

Secondary Actions

• Man Shan Hong is a regional respiratory herb rather than a universally used textbook staple, but within its home tradition it has a strong reputation for bronchitic cough.
• The leaf record should be distinguished from Man Shan Hong You, the distilled oil preparation derived from the same plant but used as a more concentrated product.

Classic Formulas

• Man Shan Hong decoction for productive cough - traditional leaf use for phlegm-heavy cough and dyspnea.
• Man Shan Hong with Xing Ren and Jie Geng - a regional antitussive pairing to open the Lung and facilitate expectoration.
• Man Shan Hong with Chen Pi and Ban Xia - a practical phlegm-transforming combination when chest fullness and sticky sputum predominate.

Classical References

• Traditional references describe Man Shan Hong as acrid, bitter, and cold, entering the Lung and Spleen to stop cough and eliminate phlegm.
• Its core indication is cough and dyspnea with excessive phlegm rather than dry throat or yin-deficient cough.
• Northeastern folk and pharmacopoeial usage expanded the herb's reputation to acute and chronic bronchitic conditions, which remains central to modern Chinese use.
