First Aid & Prevention

First 30 Minutes

• Rinse mouth with clean water if large amounts of plant material are ingested as a basic precaution
• Wash affected skin with mild soap and water if rare non-toxic irritation occurs
• Monitor for unusual symptoms, which are likely linked to misidentified plants or unrelated allergies

Contact Vet Immediately

• If your pet exhibits persistent vomiting, diarrhea, or lethargy after suspected linden ingestion, as this may indicate consumption of a misidentified toxic plant
• If you are unsure of the identity of the ingested plant, share a sample or photo with your vet for confirmation

Prevention

• Confirm the identity of linden species before allowing pet access or using plant material for human consumption
• Avoid allowing pets to forage on unknown wild plants to reduce risk of ingesting toxic lookalike species
• Store foraged plant material clearly labeled and out of reach of pets and small children

Treatment & Prognosis
