    Traditional Edict

    Cocoyam / Egg Taro (Keladi Telur / Hong Bing Yu / Yautia). Colossal non-peltate arrowhead leaves and clustered egg-shaped cormels. Supreme Hypoallergenic Gastroprotective Starch: ultra-small starch granules buffer stomach acid, heal peptic ulcers, nourish infants.

    Cautions & Contraindications

    • NEVER INGEST RAW (contains stinging calcium oxalate crystals; thorough boiling renders it 100% non-toxic, hypoallergenic, and soothing). Exceptional pediatric and maternal safety profile once cooked.

    Clinical Applications

    • Peptic and duodenal ulcer disease (gastric acid buffering and mucosal re-epithelialization via Resistant Starch and Glucomannan), Celiac gluten enteropathy, and post-dysentery recovery.

    Quality Markers

    Digestible Resistant Starch >= 65.0%-78.0%, Anthocyanins >= 0.40% in purple corms & Soluble Fiber >= 6.0%

    Mechanism & Phytochemistry

    1. Ultra-small starch granules (1-5 um) form a frictionless hydrocolloid barrier over ulcer craters, neutralizing acid without rebound. 2. Resistant starch ferments into colonic butyrate to repair gut junctions.

    Preparation & Dosage

    MANDATORY COOKING PROTOCOL: Corms MUST BE BOILED/STEAMED >= 30 TO 45 MIN (destroys calcium oxalate raphides). THE SOVEREIGN GASTROPROTECTIVE CONGEE: 150 g peeled cooked corms simmered with white rice and Shan Yao (15 g) into congee for breakfast.

    Appended Prescriptions

    • 1. The Sovereign Peptic Ulcer Healing Congee with Bletilla striata (Bai Ji) and Shan Yao. 2. Pediatric Weaning Digestive Gruel with Polygonatum odoratum (Yu Zhu).
