Purpleflower Crotalaria Herb … Safety & Interactions

Nong Ji Li · Herba Crotalariae

Contraindications

  • Pregnancy
  • Pre-existing liver disease or elevated liver enzymes
  • Paediatric use
  • Concurrent hepatotoxic drug therapy

Cautions

  • Crotalaria sessiliflora contains pyrrolizidine alkaloids, especially monocrotaline-related chemistry, and should be treated as a hepatotoxic high-risk herb rather than a casual folk tonic.
  • Short-term symptom relief or historical antitumor use does not remove the risk of cumulative liver injury, vascular toxicity, or broader heavy-exposure harm.
  • Source confusion with other Crotalaria species can worsen both efficacy uncertainty and toxicology risk.
