The dumb cane (Dieffenbachia seguine) is a popular houseplant valued for its attractive foliage and its ability to thrive in indoor environments with low light intensities.1

While these plants are adaptable, it is important to note that they are toxic if ingested. The plant contains stinging crystals called raphides, which are composed of calcium oxalate. Chewing or consuming any part of the plant can cause irritation, swelling, and inflammation of the mouth and throat, leading to temporary speechlessness. Because of this, it is essential to keep the plant out of reach of children and pets, as it is known to be toxic to cats.1
