Dutchmanspipe Fruit — Safety & Interactions

Ma Dou Ling · Fructus Aristolochiae

Contraindications

  • Pregnancy
  • Kidney disease, prior renal injury, or any suspected aristolochic acid nephropathy
  • Cough from cold deficiency rather than heat
  • Any unsupervised internal use

Cautions

  • Ma Dou Ling contains aristolochic acids, which are associated with irreversible kidney damage and urothelial cancer risk and make this herb inappropriate for casual or supplement-style use.
  • Older cough formulas containing Ma Dou Ling should not be treated as safety endorsements because the toxicology profile is now far better understood than in the classical period.
  • MSK page not found - drug interaction data not available from Memorial Sloan Kettering integrative medicine database
