Toxic component and mechanism

The toxic component in Charming Dieffenbachia is insoluble calcium oxalate crystals.

What makes this plant different

A popular cultivar of Dieffenbachia, sometimes called 'Dumb Cane' because the oral swelling it causes can temporarily impair speech in humans who chew it — the same oxalate crystals cause proportionally similar oral discomfort in pets, at a somewhat higher severity than Peace Lily or Pothos.
