Creeping buttercup Toxic?

Updated 2026-03-06| 3 min read| 1,107 found this helpful
Ranunculus repens L.
1

Toxicity is triggered when the plant is wilted or damaged, as non-toxic ranunculin breaks down into the irritant toxic compound protoanemonin.

2

Dried plants and silage stored for over 2 months are non-toxic, as protoanemonin dimerizes into harmless anemonin during storage.

3

Ingesting large quantities or long-term consumption can cause severe neurological symptoms, and even fatal respiratory paralysis in rare cases.

FAQ

Is Creeping buttercup toxic to Humans?

No explicit human symptom data recorded, but oral ingestion may cause oral irritation, blisters, gastrointestinal discomfort, and possible allergic reactions. (Low)

Is Creeping buttercup toxic to Cats?

No specific cat symptom data available, may cause oral swelling, salivation, vomiting, diarrhea and weakness after ingestion. (Low)

No specific dog symptom data available, may cause oral blisters, gastrointestinal irritation, tremors and hematuria if consumed in large amounts. (Low)

Is Creeping buttercup toxic to Horses?

Mild gastroenteritis for small intake; ingesting 2kg fresh plant or consuming for 3 weeks leads to mouth/lip blisters, erythema, salivation, vomiting, diarrhea, colic, weakness, hematuria, tremors, seizures, paralysis, rare death from respiratory paralysis. (High)

Toxicity Snapshot

Toxic PartsWhole plant, its ranunculin content is only about 5% of that of sharp or tuberous buttercup species.
Exposure RouteOral ingestion is the main exposure route; direct contact with damaged fresh plants may also cause skin and mucous membrane irritation.
Toxic CompoundsProtoanemonin; Ranunculin; Anemonin (non-toxic dimerized product of protoanemonin)

First Aid & Prevention

First 30 Minutes

  • • Stop ingestion immediately, rinse mouth thoroughly with clean water to remove residual plant matter.
  • • Do not induce vomiting unless explicitly instructed by a medical or veterinary professional.
  • • Collect remaining plant samples for accurate identification to guide follow-up treatment.

Contact Vet Immediately

  • • Ingestion of large amount of fresh creeping buttercup, or appearance of blisters, excessive salivation, vomiting or diarrhea.
  • • Neurological symptoms such as tremors, seizures or paralysis occur after ingestion.
  • • Lactating animals produce abnormally reddish or bitter-tasting milk after exposure.

Prevention

  • • Avoid grazing livestock in areas with dense growth of creeping buttercup.
  • • Ensure silage is stored for at least 2 months before feeding to eliminate residual toxicity.
  • • Keep fresh creeping buttercup plants out of reach of companion pets to avoid accidental ingestion.

Treatment & Prognosis

  • • Implement standard decontamination procedures per emergency treatment protocols.
  • • Administer mucosal protective agents to reduce irritation to the digestive tract.
  • • Provide symptomatic supportive care, antihistamines may be used if required for allergic reactions.

Target Organs

Mechanism of Action

• Non-toxic ranunculin naturally present in the plant is enzymatically split into toxic protoanemonin when the plant is wilted or physically damaged.

• Unstable protoanemonin easily dimerizes into non-toxic anemonin during drying or long-term ensiling, eliminating the plant's toxicity.

• Protoanemonin irritates skin, mucous membranes and the digestive tract, and can damage the nervous system and kidneys when absorbed in large doses.

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Cattle: May develop udder inflammation after ingestion, producing abnormally reddish, bitter-tasting milk that is unsuitable for consumption.
Small ruminants (sheep, goats): No specific recorded data, expected to develop similar mucosal irritation and gastrointestinal symptoms as horses after ingesting fresh plant material.
Confusion Risk

The following plants look similar and may be confused:

Other Ranunculus species Ranunculus spp.
Visually similar to other buttercup species with overlapping growth habitats; can be distinguished by its characteristic creeping growth habit, unlike most upright growing Ranunculus varieties.
