    Traditional Edict

    Djenkol Bean / Jering (Jering / Jengkol / Ji Ling Mu). Massive contorted dark-purple pods with disc seeds. Sovereign for Pancreatic Insulin Stimulation & Diabetes: stimulates beta-cells to lower blood glucose by up to 50%, drains dropsy. RAW INGESTION CARRIES DJENKOLISM RISK; MANDATORY COOKING & WATER.

    Cautions & Contraindications

    • DJENKOLISM TOXICOLOGY WARNING: Eating raw unsoaked seeds in acidic urine causes needle crystal blockage (flank colic, hematuria). Antidote: 2-4 g Sodium Bicarbonate orally with abundant water. CONTRAINDICATED in CKD.

    Clinical Applications

    • Type 2 Diabetes mellitus (pancreatic beta-cell insulin secretagogue and skeletal GLUT4 upregulation via Quercetin-3-glucoside), peripheral edema, and Stage 1 essential hypertension.

    Quality Markers

    Djenkolic Acid (吉令酸) >= 1.00%-2.50%, Quercetin-3-O-glucoside & Soluble Fiber >= 6.0% (HPLC MHM standard)

    Mechanism & Phytochemistry

    1. Phenolic extracts stimulate pancreatic beta-cell insulin secretion and inhibit alpha-glucosidase. 2. Djenkolic acid is insoluble in acid urine (causes sharp needle crystal blockage); alkaline pH dissolves it.

    Preparation & Dosage

    MANDATORY DETOXIFICATION PAOZHI: Soak peeled seeds in water 24-48 hours (change water 3x), boil >= 45 min in water with sodium bicarbonate, and simmer in coconut curries (Rendang Jering). Take 2 to 4 cooked seeds. DRINK >= 2 LITERS WATER ON CONSUMPTION DAY to prevent crystal stones.

    Appended Prescriptions

    • 1. The Sovereign Antidiabetic & Pancreatic Protection Synergy with Orthosiphon (Misai Kucing) and Momordica. 2. Renal Diuretic & Edema Clearing Draught with Corn Silk (Zea mays).
