Known in TCM as Bai Jiang Cao (败酱草), this acrid and bitter, slightly cold herb enters the Liver, Stomach, and Large Intestine. Traditionally, it clears heat and relieves toxicity, reduces abscess and expels pus, most often applied for pelvic inflammatory disease, appendicitis, and dysentery. Modern research has identified Triterpenoid saponins (oleanolic acid and ursolic acid glycosides) among its active constituents.

Traditional Use

Primary Actions

  • Clears heat and relieves toxicity, reduces abscess and expels pus … used for intestinal abscesses (acute appendicitis), pelvic inflammatory disease, hepatitis, dysentery, and heat toxicity causing pus formation
  • Dispels blood stasis and relieves pain … used for postpartum abdominal pain, dysmenorrhea, and stasis-heat pain in the Lower Jiao

Secondary Actions

  • Applied in gynecology … used for mastitis, tubal obstructive infertility, and pelvic endometriosis from damp-heat and blood stasis
  • Clears damp-heat in the intestines … used for ulcerative colitis, anal cryptitis, and typhoid enteritis

Classic Formulas

  • Yi Yi Fu Zi Bai Jiang San (薏苡附子败酱散) … Bai Jiang Cao as deputy with Yi Yi Ren and Fu Zi; for intestinal abscess with pus discharge in constitutionally cold patients
  • Da Huang Mu Dan Tang (大黄牡丹汤) … with Da Huang, Mu Dan Pi, Tao Ren, Hua Shi; for acute appendicitis with heat and blood stasis

Modern Research

Active Compounds

  • Triterpenoid saponins (oleanolic acid and ursolic acid glycosides) … primary constituents of P. scabiosaefolia; anti-inflammatory, antitumor, and hepatoprotective
  • Iridoids (patrinoside, villosoides) … anti-inflammatory and neuroprotective glycoside compounds
  • Flavonoids (quercetin, rutin, kaempferol, luteolin) … antioxidant and anti-inflammatory secondary metabolites
  • Volatile oils … the characteristic soy-sauce odor compounds including isovaleric acid and β-caryophyllene
  • Polysaccharides … immunomodulatory macromolecules

Studied Effects

  • Comprehensive phytochemistry and pharmacology … 233 compounds identified across two Patrinia species; triterpenoid saponins and volatile oils as main P. scabiosaefolia constituents; anti-inflammatory, antibacterial, antitumor, hepatoprotective activities confirmed; clinical applications validated in pelvic inflammatory disease, hepatitis, and gynecological conditions (PMID 32846192)
  • Novel iridoids … nine unique iridoids and iridoid glycosides discovered from P. scabiosaefolia including three new iridoids and six new iridoid glycosides; structural characterization expands known phytochemical profile (PMID 33855012)

Safety & Interactions

Contraindications

  • Spleen-Qi deficiency without heat toxicity … acrid-bitter cold nature damages Spleen Yang with prolonged use; avoid in cold-deficient patterns without abscess or heat toxin
