Is umbrella tree toxic to dogs?
The umbrella tree (Schefflera spp.) is toxic to dogs. The toxic principles are an irritant sap and insoluble calcium oxalate crystals known as raphides. Raphides are tiny needle-like crystals that are arranged in bundles. When the dog chews on any part of the plant, these needle-sharp crystals penetrate the oral mucosa causing intense pain, burning and in some cases, swelling.
