Chinaroot Greenbrier Rhizome — Classic Formulas

Ba Qia · Rhizoma Smilacis Chinensis

Primary Actions

  • Dispels wind-damp and relieves painful obstruction - Ba Qia is used for chronic joint pain, rheumatic arthralgia, low-back soreness, and heaviness or numbness in the limbs when dampness lodges in the channels.
  • Resolves toxic heat and reduces swelling - traditional indications extend to sores, carbuncles, damp-toxic skin eruptions, hemorrhoids, and older venereal-damp-heat presentations such as gonorrhea or syphilitic lesions.
  • Promotes urination and separates turbidity - it is applied when damp-heat causes strangury, turbid urine, leukorrhea, or lingering lower-burner congestion.
  • Assists in lingering dysenteric and damp-toxic digestive disorders - folk and regional use includes gastroenteritis, dysentery, and other inflammatory intestinal complaints with heat and damp accumulation.

Classic Formulas

  • Ba Qia Jiu (菝葜酒) - folk rhizome-in-wine preparation used for chronic rheumatic pain, channel obstruction, and lower-limb stiffness.
  • Ba Qia with Tu Fu Ling and Ku Shen (菝葜配土茯苓苦参) - regional damp-toxic pairing for genital, skin, or lower-burner disorders with heat, itching, swelling, or discharge.
  • Ba Qia with Bian Xu or Jin Qian Cao (菝葜配萹蓄金钱草) - used when urinary turbidity, strangury, damp-heat, and painful lower-burner obstruction occur together.

Classical Text References

  • A recent ethnopharmacology review of Smilax china notes long Chinese use for pain, rheumatic disorders, dysentery, pelvic inflammation, burns, and damp-toxic conditions, citing early materia medica back to the Supplementary Records of Famous Physicians.
  • Yin Yang House places Ba Qia among herbs that dispel wind-damp, entering the Kidney and Liver channels and emphasizing arthritic pain, diarrhea or dysentery, skin infection, gonorrhea, syphilis, hemorrhoids, and leukorrhea.
  • SOURCE NOTE: some English TCM databases describe Ba Qia as sweet-sour and slightly warm, while pharmacopoeia-oriented summaries often describe it as sweet-slightly bitter and neutral; this entry follows the latter because the schema requires a single temperature value.
