Most Trees Are Not Dangerous,

unless you fall out of them, 

or one falls on you!, but this tree is the very devil itself, along the coasts of the Caribbean, Central America, the northern edges of South America and even in southern Florida, you can find a nice-looking beach tree, often loaded with small, very greenish-yellow fruits similar to apples, whose pleasant aroma invites you to take a bite. It is best not to fall into that temptation, because it is a poisonous fruit, known as the Chamomile of death or tree of death (Hippomane mancinella), it is sometimes known as the beach apple, the plant bears another name in Spanish, arbol de la muerte, which literally means "tree of death". According to the Guinness World Records, the manchineel tree is in fact the most dangerous tree in the world, as explained by the Florida Institute of Food and Agricultural Sciences, all parts of manchineel are extremely poisonous, and "interaction with and ingestion of any part of this tree may be lethal" the tree belongs to the large and diverse Euphorbia genus, which also contains the decorative Christmas poinsettia, the tree produces a thick, milky sap, which oozes out of everything - the bark, the leaves and even the fruit - and can cause severe, burn-like blisters if it comes into contact with skin, that's because the sap contains a range of toxins; it's thought that the most serious reactions come from phorbol, an organic compound that belongs to the diterpene family of esters, because phorbol is highly water-soluble, you don't even want to be standing under a manchineel when it's raining - the raindrops carrying the diluted sap can still severely burn your skin, "The real death threat comes from eating its small round fruit," Ella Davies writes for the BBC. "Ingesting the fruit can prove fatal when severe vomiting and diarrhoea dehydrate the body to the point of no return." the tree of death indeed!
