Prepared Earthworm … Safety & Interactions

Zhi Di Long · Pheretima Praeparata

Contraindications

  • Cold deficiency patterns without heat, wind, or obstruction
  • Known allergy to animal-derived medicines
  • Active bleeding disorders without close supervision

Cautions

  • Di Long extracts and lumbrokinase-type products may affect coagulation and should be treated more cautiously than the herb's traditional reputation alone might suggest.
  • Commercial Pheretima products can face quality and contamination issues, including documented heavy-metal concerns in some market samples.
  • Prepared earthworm is a potent animal medicine, not a casual supplement or self-care food item.
