Notes
Swiss-cheese plant is a popular container plant because of its ability to withstand the wide range of conditions encountered in the home. 

The leaves can cause problems if chewed by humans or family pets. Experimental rats and mice died after they were fed plant extracts. General symptoms of poisoning are immediate and painful with aphonia (loss of voice), blistering, hoarseness, irritation of the mouth. Urticaria (an allergic disorder characterized by raised edematous (watery swelling) patches of skin) accompanied by intense itching can occur in sensitive individuals who ingest the ripened fruit.
