Dieffenbachia is not considered safe for children or pets if ingested. The plant contains calcium oxalate crystals that can cause irritation, swelling, burning sensations in the mouth, drooling, and difficulty swallowing. For safety, place the plant out of reach of curious children and animals, and wear gloves when pruning if you have sensitive skin. If someone chews or eats part of the plant and experiences severe symptoms, contact a healthcare provider or veterinarian promptly.
