    Traditional Edict

    Slender Amaranth / Green Wild Spinach (Bayam Pasir / Zhou Guo Xian). Spineless wild amaranth with wrinkled rugose seed capsules. Sovereign for clearing blazing summer-heat fevers, draining burning damp-heat strangury (Re Lin), clearing red swollen eyes, and resolving dysentery.

    Cautions & Contraindications

    • Distinguish from Amaranthus spinosus (viridis is completely spineless with wrinkled fruit capsules). Exceptional nutritional, dietary, and pediatric safety profile. Safe in pregnancy and lactation.

    Clinical Applications

    • Summer heatstroke and febrile dehydration, acute urinary tract infections with burning dysuria, acute catarrhal conjunctivitis with photophobia, and bacillary dysentery.

    Quality Markers

    Rutin >= 1.50%, Quercetin-3-O-glucoside, Soluble Fiber >= 4.5% & Potassium >= 3.5% (HPLC standard)

    Mechanism & Phytochemistry

    1. Rutin and flavonoids downregulate pyrogenic cytokines and conjunctival PGE2. 2. High organic potassium salts stimulate renal osmotic diuresis to purge urinary pathogens. 3. Soluble fiber binds gut toxins.

    Preparation & Dosage

    THE SOVEREIGN BAYAM PASIR SUMMER-HEAT & DYSURIA BROTH: 150 g fresh tender wild greens simmered in clear vegetable soup with shallots and garlic for 5 min; consumed warm with meals during hot weather. Dysuria tea: 30 to 50 g fresh roots boiled in 500 mL water.
