Toxicity Snapshot

Toxic PartsWhole plant
Exposure RouteIngestion is the primary exposure route; dermal contact may cause mild irritation in sensitive individuals
Toxic CompoundsThujone; Thujyl alcohol; Sesquiterpene lactones (artabsin, absinthin, isoabsinthin, anabsin, artabin, ketopelenolide A, ketopelenolide B, arbasin); Essential oils (0.3-1.3% of plant weight)

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

Scientific NameArtemisia absinthium L.
AliasesAbsinthium、Oldman wormwood
Toxicity Grade
HumansModerate
CatsLow
DogsModerate
HorsesModerate
Target Organs
Gastrointestinal tractKidneysCentral nervous system
Mechanism of Action

• 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

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Sheep: Ingestion of 340g of related Artemisia tridentata per day causes severe necrotizing rumenitis leading to death within 48 hours; preceding symptoms include lethargy, weakness, rumen stasis, and nasal foam discharge
Cattle: No species-specific data available, expected to experience similar gastrointestinal, neurological, and renal effects as other ruminants following large quantity ingestion
Confusion Risk

The following plants look similar and may be confused:

Other Artemisia species Artemisia spp.
Most Artemisia species share similar feathery aromatic foliage; toxic varieties have high thujone content, while non-toxic species including common mugwort (A. vulgaris) and tarragon (A. dracunculus) have negligible thujone levels
Common groundsel Senecio vulgaris
Has similar lobed foliage and yellow composite flowers; Senecio species contain highly toxic pyrrolizidine alkaloids, and can be distinguished by their distinct daisy-like individual flowers compared to Artemisia's tiny clustered flower heads
Common tansy Tanacetum vulgare
Has similar fern-like foliage and yellow flowers; tansy also contains thujone and other toxic compounds, and can be distinguished by its flat-topped clusters of bright yellow button-shaped flowers
