According to this traditional description, Sophora root "Clears Heat and Dries Dampness," "Dispels Wind and Stops Itching," and "Promotes Urination" – TCM concepts that stand for resolving aggressive, stagnant fluids that sink into the lower body or erupt on the skin surface . When damp-heat and wind accumulate, related discomforts such as severe genital itching, weeping skin rashes, or burning urination can arise . Sophora root helps perform this deep draining, cooling, and antiparasitic effect.In TCM formulas, Sophora root (Ku Shen) is seen as a highly effective botanical that helps support normal dermatological comfort, clear intense localized heat, and balance the lower digestive and urinary tracts . It is traditionally used to promote clear, comfortable urination, soothe irritated and weeping skin sores, alleviate intimate discomforts, and foster a clean, balanced internal state free of stagnant dampness.Botanical Composition and ResearchSophora root (Ku Shen) contains primarily quinolizidine alkaloids (most notably matrine and oxymatrine) and various flavonoids (such as kurarinone) .
