Known in TCM as Ku Shen Jian (苦参碱), this bitter, cold herb enters the Heart, Liver, Stomach, Large Intestine, and Bladder. Traditionally, it isolated quinolizidine alkaloid concentrated from Ku Shen (Sophora flavescens root); carries forward Ku Shen's Heat-clearing, Damp-drying, and toxin-resolving actions in a purified form, most often applied for hepatitis, eczema, and cancer. Modern research has identified Matrine among its active constituents.

Traditional Use

Primary Actions

  • Isolated quinolizidine alkaloid concentrated from Ku Shen (Sophora flavescens root); carries forward Ku Shen's Heat-clearing, Damp-drying, and toxin-resolving actions in a purified form
  • Used in modern Chinese clinical practice, often by injection or standardized extract, for Damp-Heat skin conditions and Heat-toxin patterns

Classical References

  • Not a classical single herb in its own right; represents the principal bioactive alkaloid of Ku Shen (Sophora flavescens), described in traditional materia medica for clearing Heat and drying Dampness

Modern Research

Active Compounds

  • Matrine (quinolizidine alkaloid)
  • Oxymatrine (related oxidized alkaloid)

Studied Effects

  • Antiviral activity against hepatitis B virus demonstrated for matrine-type alkaloids isolated from Sophora flavescens
  • Anti-inflammatory, antioxidant, antifibrotic, and anticancer activity reported across preclinical studies
  • Documented hepatotoxicity and neurotoxicity at high doses, a major factor limiting clinical use

Safety & Interactions

Contraindications

  • Pregnancy
  • Pre-existing liver impairment

Cautions

  • Documented hepatotoxicity and neurotoxicity at high or prolonged dosing; use only under practitioner and, where applicable, medical supervision
  • Not equivalent in dosing or safety profile to whole Ku Shen root; purified alkaloid forms carry a narrower margin of safety

Drug Interactions

  • Theoretical additive hepatotoxic risk with other liver-metabolized medications
