Giant dumbcane (Dieffenbachia amoena) is an indoor ornamental plant. Experimental work on rodents proved the toxicity of leaf and stem tissue from giant dumbcane. Death occurred after administration of 3.0 g of plant extract in 10.0 mL of liquid per 100 g of body weight (Der Marderosian et al. 1976).
