Mistletoe (Phoradendron flavescens). Deadly parts: All parts, especially the berries. Toxic toll: Munching on a couple of leaves, berries, or shoots—or drinking mistletoe-flavored tea—will cause abdominal pain and diarrhea. Cases where mistletoe ingestion were fatal involved gastroenteritis (an inflammation of the stomach and small intestine), followed by cardiovascular collapse. The berries are particularly potent when it comes to pets, so mind your cats and dogs around this plant.Photo by Andrew Dunn
