Though many people believe that poinsettias are poisonous, ingesting them will lead to nothing more than a stomachache. They are safe to have around the house, though owners should take care when handling any broken stems or leaves, as they release a sap that can lead to an itchy rash. If you cannot wear gloves when pruning or handling a poinsettia, make sure that you do not touch your eyes before you are able to wash your hands.
