Severe plant poisoning from hemlock water dropwort is rare in adults. Accidental ingestion caused prolonged seizures and respiratory failure due to the toxin oenanthotoxin.

Area of Science:

  • Toxicology
  • Botany
  • Emergency Medicine

Background:

  • Severe plant poisoning is infrequent in adult populations.
  • Accidental ingestion of toxic plants can lead to severe health consequences.
  • Distinguishing between similar-looking plants is crucial for preventing poisoning.

Observation:

  • Two adult cases of hemlock water dropwort root ingestion are presented.
  • Patients mistakenly identified hemlock water dropwort roots as wild parsnip.
  • One patient experienced prolonged convulsions, severe metabolic acidosis, and respiratory distress.

Findings:

  • The severe clinical presentation necessitated mechanical ventilation.
  • The presence of the toxin, oenanthotoxin, was confirmed in gastric aspirate.

Related Experiment Videos

  • High-performance liquid chromatography (HPLC) was utilized for toxin quantification.

    • Implications:

    • This case highlights the potential severity of hemlock water dropwort poisoning in adults.
    • Accurate plant identification is critical to prevent accidental toxic ingestions.
    • Early detection and supportive care, including mechanical ventilation, are vital for managing severe poisoning.
