    Traditional Edict

    Hollow-Stemmed Blumea (Sembung Rongga / Guan Jing Ai Na Xiang). Hollow fragrant stems with yellow flower heads. Sovereign for Relieving Bronchial Spasms & Gastrointestinal Gas: brewing the tea clears tenacious phlegm, relieves postprandial flatulence, and dispels wind-cold.

    Cautions & Contraindications

    • Aromatic volatile terpenes (do not boil excessively; short boil 5-10 min). High clinical and respiratory safety profile. Safe during lactation; moderate internal doses in pregnancy.

    Clinical Applications

    • Acute and chronic bronchitis cough with profuse phlegm (ciliary secretolysis and bronchodilation via 1,8-Cineole and Caryophyllene), functional flatulent dyspepsia, and wind-cold fevers.

    Quality Markers

    1,8-Cineole >= 25.0%, beta-Caryophyllene, L-Borneol & Essential Oil >= 1.20% v/w (GC-MS standard)

    Mechanism & Phytochemistry

    1. 1,8-Cineole stimulates bronchial goblet cell serous secretion, thinning tenacious mucus. 2. beta-Caryophyllene binds CB2 receptors, reducing visceral gastrointestinal spasms.
