Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Remove all remaining plant material from the exposed person/animal's mouth immediately
- • Rinse the mouth thoroughly with cool clean water to reduce mucous membrane irritation
- • Collect a sample of the ingested plant to share with medical or veterinary staff for accurate identification
Contact Vet Immediately
- • If a cat, dog, or horse has ingested any quantity of this plant
- • If symptoms including vomiting, excessive salivation, lethargy, or abdominal pain appear after exposure
- • If a grazing animal is confirmed to have accessed and eaten this plant, to monitor for kidney damage risk
Prevention
- • Keep potted plants out of reach of household pets, and avoid planting in pastures or areas accessible to horses or other grazing livestock
- • Label plants clearly to alert caregivers, pet owners, and farm staff of their toxic status
- • Teach children not to chew or consume any unknown house or garden plant material
Treatment & Prognosis
- • Veterinarians may administer gastrointestinal decontamination (emetics, activated charcoal) for recent ingestions in small animals
- • Supportive intravenous fluid therapy will be provided to reduce kidney damage risk, especially for horses and other grazing animals
- • Symptomatic care for pain, irritation, and vomiting will be administered as needed for presenting clinical signs
Professional Toxicology
• Soluble calcium oxalate crystals irritate oral, esophageal, and gastrointestinal mucous membranes immediately upon ingestion
• Absorbed oxalates bind to circulating calcium in the body, forming sharp crystals that accumulate in kidney tissue and cause organ damage
