Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • If ingested, do not induce vomiting unless explicitly directed by a medical/veterinary professional, avoid feeding any additional substances
- • Wash exposed skin thoroughly with mild soap and cool water for 10-15 minutes if dermal contact occurs
- • Collect remaining plant material for formal identification to guide targeted care
Contact Vet Immediately
- • Any confirmed or suspected ingestion of the plant by pets or livestock
- • Onset of abnormal symptoms including seizures, gastrointestinal distress, unusual behavior, or vision changes post exposure
- • Persistent or worsening dermal reactions after washing affected areas
Prevention
- • Keep the plant out of reach of children, pets, and grazing livestock
- • Avoid unregulated homemade absinthe or herbal products containing this plant, as thujone content is unmonitored
- • Learn to identify this plant and its toxic lookalikes to avoid accidental exposure
Treatment & Prognosis
- • Perform gastrointestinal decontamination (activated charcoal, gastric lavage) where medically appropriate shortly after ingestion
- • Provide symptomatic supportive care including seizure control, fluid therapy to protect renal function, and gastrointestinal symptom management
- • Monitor organ function (kidney, neurological status) for 24-48 hours post exposure to catch delayed toxic effects
Professional Toxicology
• Thujone interacts with GABA receptors in the central nervous system, triggering seizures and neurological abnormalities
• Sesquiterpene lactones cause direct gastrointestinal irritation and contribute to renal tissue damage
• Concentrated plant essential oil has significantly higher toxicity than raw, unprocessed plant material
