Corncockle Toxic?

Updated 2026-03-06| 3 min read| 4,999 found this helpful
Agrostemma githago L.
1

Mature seeds contain the highest toxin concentration (6-7%), and are the primary source of poisoning via contaminated feed or flour.

2

Young animals are significantly more sensitive to poisoning than adults, with acute poisoning cases common in juveniles.

3

All poisoning cases can be prevented by thorough seed cleaning to remove corncockle contamination from feed and grain supplies.

Toxicity Snapshot

Toxic PartsEntire plant, especially mature seeds
Exposure RouteIngestion of corncockle-contaminated feed, flour, or grain; accidental consumption of plant material by grazing animals
Toxic CompoundsTriterpene saponins (githagosid, agrostemmasaponine 1, agrostemmasaponine 2); Orcialanin (phenylalanine derivative); Agrostin (ribosome-inactivating protein)

First Aid & Prevention

First 30 Minutes

  • • Immediately remove all potentially contaminated feed or plant material from access of exposed individuals.
  • • Induce vomiting only for recently exposed species capable of vomiting (e.g. dogs, not horses/rabbits) if the individual is alert and not already vomiting.
  • • Offer small amounts of clean water to reduce mucous membrane irritation if the individual is able to swallow normally.

Contact Vet Immediately

  • • Any confirmed or suspected ingestion of corncockle-contaminated material, especially in young animals or horses.
  • • Presence of symptoms including excessive salivation, diarrhea, abdominal pain, difficulty swallowing, or abnormal behavior after exposure.
  • • Cases where feed/grain supplies are confirmed to be contaminated with corncockle seeds, even if no symptoms are observed.

Prevention

  • • Implement thorough seed and grain cleaning processes to remove corncockle seeds from feed, flour, and food supplies.
  • • Inspect grazing pastures regularly to remove corncockle plants before they produce mature toxic seeds.
  • • Store all feed and grain in sealed, contamination-proof containers to avoid contact with wild corncockle seeds.

Treatment & Prognosis

  • • Perform appropriate decontamination (e.g. activated charcoal administration for recent ingestions) for the affected species.
  • • Provide symptomatic supportive care including fluid therapy for dehydration, pain relief for colic, and mucous membrane protection.
  • • Immediately switch exposed livestock or companion animals to fully uncontaminated feed supplies.

Scientific NameAgrostemma githago L.
AliasesCommon corncockle、Corn cockle、Kornrade (German)、Nielle des blés (French)、Gittaione comune (Italian)
Toxicity Grade
HumansHigh
CatsHigh
DogsHigh
HorsesHigh
Target Organs
Gastrointestinal tractOral and respiratory mucous membranesCardiovascular system (suspected)
Mechanism of Action

• Triterpene saponins irritate gastrointestinal and respiratory mucous membranes, causing inflammation and local tissue damage.

• Ribosome-inactivating protein agrostin disrupts cellular protein synthesis, leading to systemic toxic effects.

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Cattle: High sensitivity; symptoms include loss of appetite, increased thirst, suppressed rumination, and bloating after ingestion.
Sheep/Goats: Sensitive to poisoning, with juvenile individuals at far higher risk of acute toxic reactions.
Pigs: Sensitive to contaminated feed, presenting gastrointestinal distress including diarrhea and abdominal pain.
Rabbits: Sensitive to poisoning, with no vomiting observed; presents mucous membrane inflammation and diarrhea after ingestion.
Poultry: Sensitive to seed contamination in feed, with young poultry at highest risk of acute fatal poisoning.
Confusion Risk

The following plants look similar and may be confused:

Other pink family plants Various Caryophyllaceae spp.
Visually similar to other non-toxic to toxic members of the Caryophyllaceae family; corncockle is distinguished by its deep purple-pink flowers with narrow pointed petals and long hairy sepals that extend past the petals.
