Contraindications

  • Pregnancy unless specifically prescribed
  • Loose stool, severe deficiency, bowel obstruction, or dehydration
  • Long-term unsupervised use

Cautions

  • Prepared rhubarb is milder than raw Da Huang but still not a casual digestive aid.
  • Overuse can still cause diarrhea, electrolyte disturbance, and gastrointestinal irritation.
  • Chronic or heavy use of rhubarb preparations carries genuine safety concerns, including liver-related questions discussed in the literature.
