Do Not Stand Under The Poisonous Manchineel Tree
Every part of the manchineel tree, from its small green fruits to its sap, is toxic. In fact, the Florida Institute of Food and Agricultural Sciences warns that "interaction with and ingestion of any part of this tree may be lethal." A single bite of the fruit can end in gastrointestinal bleeding, a closed throat, and hours of pain, if not death. The sap, meanwhile, causes blisters and burns on both skin and paint. People are cautioned not to stand under these trees in the rain because the water droplets could transfer sap to their bodies! The trees are endangered, but can be found in Florida, the Bahamas, the Caribbean, Central America, and northern South America.
