Hi Jennifer.
@jvdubb
The nickname for Dieffenbachia is Dumb Cane...Eating any part of the plant results in temporary difficulty or inability to speak. The culprit is Raphides.
"Raphides are needle-shaped crystals of calcium oxalate as the monohydrate or calcium carbonate as aragonite, found in more than 200 families of plants. Both ends are needle-like, but raphides tend to be blunt at one end and sharp at the other."
