manchineel treet looks unassuming enough, often little more than a shrubby bush, but sometimes growing into a tree thats around 15 meters (50 ft) tall. Its found mainly in the Southeastern United States, the Caribbean, and Central America. Its bark is gray-brown, and its leaves are a bright and shiny green. The fruits of the tree are sweet-smelling and attractive.Every part of the tree is poisonous, and just coming in contact with the tree can be potentially lethal. The leaves and bark contain a poison that will irritate the skin and cause severe blisters. The milk-white sap that leaks from wounds in the tree will also cause severe blistering. If sap touches a persons mucous membranes, it can cause severe burns.The fruit makes the tree even more deadly. The fruits look like small green apples, only an inch or two in diameter. The fruits are very sweet-smelling, and those who are braveor foolhardyenough to eat them say that they even taste good. But eating just a small amount will leave blisters and burns on your mouth and throat. In addition, the raw, soft tissues of your digestive tract will begin to swell and blister after eating just the smallest bite of the fruit. Larger amounts are deadly.
