Traditional Edict
Cockspur Thorn / Stone-Piercing Root (Pokok Duri Berakar / Chuan Po Shi / Gou Ji / Radix Cudraniae). Thorny scandent shrub with bright golden-yellow roots. Sovereign for Chronic Hepatitis B & Pelvic Adhesions: boiled golden root induces apoptosis in activated hepatic stellate cells (HSC-T6), reverses liver fibrosis, clears PID.
