    Traditional Edict

    True Ceylon Cinnamon / Sri Lanka Cinnamon (Kayu Manis Ceylon / Zhen Rou Gui / Xi Lan Rou Gui). Gossamer-thin multi-layered golden compound quills. Empress of Liver-Safe Insulin Sensitization: ultra-low coumarin (<0.004%) makes it the only cinnamon safe for daily lifelong diabetic and lipid control.

    Cautions & Contraindications

    • TRUE CEYLON IDENTIFICATION: Fragile multi-layered papery compound quills (resembling rolled cigars) with delicate sweet scent (Coumarin <0.004%). Exceptional clinical, metabolic, and liver safety profile.

    Clinical Applications

    • Type 2 Diabetes mellitus and insulin resistance (insulin receptor autophosphorylation and skeletal muscle GLUT4 glucose disposal via A-Type Proanthocyanidins >= 2.50%), hyperlipidemia, and functional cold dyspepsia.

    Quality Markers

    Cinnamaldehyde >= 65.0%-75.0% of oil, Eugenol >= 5.0%-10.0%, A-Type Proanthocyanidins >= 2.50% & Coumarin < 0.004% (<40 ppm) (HPLC liver-safe standard)

    Mechanism & Phytochemistry

    1. A-type proanthocyanidins inhibit PTP1B (IC50=2.1 uM) and stimulate GLUT4 translocation. 2. Ultra-low coumarin (<0.004% vs. Cassia up to 1.0%) prevents CYP2A6 hepatotoxicity.

    Preparation & Dosage

    THE DAILY LIVER-SAFE CEYLON CINNAMON DIABETIC TEA: 2 to 3 g freshly ground True Ceylon Cinnamon powder steeped in 300 mL boiling water for 10 min; drink warm with meals (lowers postprandial glucose). Safe for indefinite daily long-term use. Standardized extract: 250 to 500 mg twice daily.

    Appended Prescriptions

    • 1. The Sovereign Type 2 Diabetes Glycemic Stabilization Tea with Mulberry leaf (Sang Ye) and Bitter melon. 2. Spleen-Warming Digestive & Cholesterol Elixir with raw wild honey.
