Cineraria Toxic?

Updated 2026-03-06| 2 min read| 4,795 found this helpful
Cineraria
1

All plant parts are toxic; alkaloids remain active in dried forage, silage, and are not destroyed by cooking.

2

Severely toxic to birds, pigs, horses, cattle, and chickens; poisoning often has fatal outcomes with no effective treatment available.

3

Chronic toxicity symptoms may appear up to 6 months after ingestion, with rapid progression to fatal terminal stages once damage advances.

FAQ

Is Cineraria toxic to Humans?

No specific human poisoning cases documented, but ingestion of pyrrolizidine alkaloid-containing plants carries known liver damage risk. (Moderate)

Is Cineraria toxic to Cats?

No specific cat toxicity data available; exposure should be avoided due to confirmed toxic alkaloid content. (Low)

Is Cineraria toxic to Dogs?

No specific dog toxicity data available; exposure should be avoided due to confirmed toxic alkaloid content. (Low)

Is Cineraria toxic to Horses?

May develop progressive seneciosis (Schweinsberger disease); acute poisoning is often fatal within days, chronic symptoms appear 3 days to 6 months post-ingestion. (High)

Toxicity Snapshot

Toxic PartsAll parts of the plant, including dried material in forage and silage
Exposure RouteIngestion is the primary exposure route; dermal contact poses minimal risk unless plant material is ingested after contact.
Toxic CompoundsJacobin; Jaconin; Jacodin; Senecionine; Retrorsine; Seneciphylline; Senkirkine; Oxalates

First Aid & Prevention

First 30 Minutes

  • • Immediately remove all remaining plant material from reach to prevent further ingestion.
  • • Induce vomiting only if explicitly directed by a medical/veterinary professional within 1 hour of confirmed ingestion.
  • • Collect leftover plant material for accurate identification to guide care decisions.

Contact Vet Immediately

  • • If any ingestion of the plant is suspected, even if no initial symptoms are present.
  • • If lethargy, loss of appetite, jaundice, or unusual behavior appear after known exposure.
  • • If livestock feed is confirmed to be contaminated with cineraria material.

Prevention

  • • Avoid planting cineraria in areas accessible to pets, livestock, or foraging children.
  • • Inspect all livestock forage and silage for cineraria contamination before feeding.
  • • Never dispose of cineraria trimmings in areas accessible to any animal species.

Treatment & Prognosis

  • • No specific curative treatment exists for pyrrolizidine alkaloid poisoning from this plant.
  • • Immediately discontinue all feed contaminated with cineraria material.
  • • Veterinary-administered supportive care may slow liver damage progression, but prognosis is poor for symptomatic animals.

Professional Toxicology

Scientific NamePericallis x hybrida (Scheidw.) B.Nord.
AliasesPericallis Hybrid、Garden Cineraria、Louse Plant、Senecio Cineraria
Toxicity Grade
HumansModerate
CatsLow
DogsLow
HorsesHigh
Target Organs
LiverGastrointestinal tract
Mechanism of Action

• Pyrrolizidine alkaloids are metabolized in the liver into reactive toxic metabolites that cause irreversible liver cell damage and veno-occlusive disease.

• Toxins are heat-stable and remain active in dried plant material, silage, and after cooking.

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Birds: Severely toxic (+++); ingestion often leads to fatal poisoning.
Pigs: Highest known sensitivity to toxins; acute ingestion almost always has fatal outcomes.
Chickens: High sensitivity; 5x more resistant than pigs but still at high risk of fatal poisoning.
Cattle: High sensitivity; 14x more resistant than pigs, may develop chronic progressive seneciosis after ingestion.
Rats: Moderate resistance; 50x more resistant than pigs.
Mice: Low sensitivity; 150x more resistant than pigs.
Sheep and Goats: Lowest documented sensitivity; 200x more resistant than pigs.
Confusion Risk

The following plants look similar and may be confused:

Aster Aster sp.
Visually similar to cineraria due to shared composite flower structure; asters are non-toxic, while cineraria contains dangerous pyrrolizidine alkaloids.
