Symptoms appear rapidly after contact or ingestion, varying between skin exposure and internal consumption of the plant.
- Oral Contact (Chewing/Sucking): Immediate stinging, burning, and swelling of lips, tongue, and throat. Excessive drooling and refusal to eat are early signs in pets.
- Skin Contact (Sap): Redness, itching, and a burning rash develop within minutes. Blistering is rare but possible in sensitive individuals.
