Supreme Sovereign for Kidney Stone Expulsion & Spasmolysis (Patha): bisbenzylisoquinolines block L-type calcium channels, relax ureters, dissolve stones, soothe cramps.

    Cautions & Contraindications

    • Potent smooth muscle relaxant. High clinical and urological safety profile. Avoid high medicinal doses during early pregnancy (mild uterine tone modulation). Safe during lactation.

    Clinical Applications

    • Urolithiasis and nephrolithiasis (calcium oxalate crystal dissolution and ureteral smooth muscle spasmolysis via Hayatin and Bebeerine >= 0.80%), severe spasmodic dysmenorrhea, and acute dysuria.

    Quality Markers

    Hayatin (锡生藤碱), Bebeerine (比枯枯灵碱) >= 0.80%, Curine & Total Bisbenzylisoquinoline Alkaloids >= 2.50% (HPLC standard)

    Mechanism & Phytochemistry
