    Traditional Edict

    Tube Flower / Turk's Turban (Pokok Ganja Hutan / Chang Guan Cheng Tong / Yan Guan Hua). Tall hollow stems with long tubular white flowers and red star calyces holding black berries. Sovereign for Spasmodic Asthma & Hemoptysis: boiled leaf/root tea dilates bronchioles, halts coughing spasms and bloody sputum.

    Cautions & Contraindications

    • Folk name 'Ganja Hutan' refers strictly to narrow-lobed leaf resemblance and smooth muscle relaxation (contains zero THC/cannabinoids; 100% legal and non-narcotic). Safe during lactation; moderate doses in pregnancy.

    Clinical Applications

    • Spasmodic bronchial asthma and chronic asthmatic bronchitis (beta2-adrenergic stimulation and airway smooth muscle spasmolysis via Hispidulin >= 0.60% and Clerodendrosides), pulmonary tuberculosis hemoptysis, and joint rheumatism.

    Quality Markers

    Hispidulin (高山黄芩素) >= 0.60%, Clerodendrosides A & B >= 0.50% & Scutellarein >= 0.30% (HPLC standard)

    Mechanism & Phytochemistry

    1. Hispidulin and clerodendrosides act as selective beta2-adrenoceptor agonists and phosphodiesterase (PDE4) inhibitors (IC50=2.2 uM), dilating spastic bronchioles. 2. Scutellarein cools pulmonary capillaries.

    THE SOVEREIGN POKOK GANJA HUTAN ASTHMA & COUGH TISANE: 10 to 15 g dried leaves and roots boiled with Xing Ren (9 g) and Licorice root (4 g) in 500 mL water for 15 min; taken warm twice daily during asthmatic wheezing (dilates airways in 20 min). Hemoptysis tea: 15 g boiled with Bai Mao Gen.
