Rhizome of Chinese Goldthread … Safety & Interactions

Huang Lian · Rhizoma Coptidis

Contraindications

  • Spleen and Stomach deficiency-cold
  • Loose stool or poor appetite without true damp-heat or fire
  • Jaundiced neonates or use around newborns without specialist oversight

Cautions

  • Huang Lian is intensely bitter and cold and can weaken already fragile digestion.
  • Berberine-rich preparations are not automatically equivalent to crude-decoction Huang Lian slices, but both deserve interaction awareness.
  • This broader Huang Lian page should not be read as chemically or clinically separate from the already-live Chuan Huang Lian lane.
