In 1999, British radiologist Nicola Strickland went on holiday with a friend to the Caribbean island of Tobago. While exploring a deserted beach looking for seashells, the pair came upon a number of small, round, yellow-green fruits scattered among the fallen coconuts and mangoes. Intrigued, they decided to try the fruits and found them to be pleasantly sweet. But that pleasure was not to last. In a 2000 article in the British Medical Journal, Strickland describes what happened next:
“Moments later we noticed a strange peppery feeling in our mouths, which gradually progressed to a burning, tearing sensation and tightness of the throat. The symptoms worsened over a couple of hours until we could barely swallow solid food because of the excruciating pain and the feeling of a huge obstructing pharyngeal lump.
Over the next eight hours our oral symptoms slowly began to subside, but our cervical lymph nodes became very tender and easily palpable. Recounting our experience to the locals elicited frank horror and incredulity, such was the fruit’s poisonous reputation.”
Indeed, Strickland and her friend were extraordinarily lucky to survive their ordeal, for the tree the innocuous-looking fruit had fallen from was none other than the Manchineel, a plant so extraordinarily toxic that one cannot touch it, shelter beneath it, or even breathe the air around it without entering a world of hurt. It is widely considered to be the most dangerous tree in the world.
Hippomane Mancinella, also known as the “Beach Apple” or, in Spanish, Manzanilla de la Meutra – the “little apple of death” – is a small shrub-like evergreen tree native to southern Florida, the Caribbean, Mexico, Central America, and northern South America. Reaching up to 15 metres in height, it is mostly found on beaches or in brackish swamps, where it often grows between mangrove trees. Manchineel is a member of the Spurges, a large family of plants that includes the holiday poinsettia. But while, contrary to popular belief, eating a poinsettia will not hurt you nor your pets in the slightest, the Manchineel packs an altogether nastier punch. Every part of the tree, from the roots to the leaves, is filled with a milky, latex-like sap containing a deadly cocktail of toxins including phorbol, hippomanin, mancinellin, apogenin, phloracetophenone, and physostigmine. Of these, perhaps the nastiest is phorbol, a highly caustic chemical which on contact with the skin inflicts large, painful blisters and if splashed in the eyes induces temporary blindness. Even breathing the air close to the tree is enough to cause slight lung damage. Phorbol is also highly soluble in water, meaning that anyone foolish enough to shelter under a Manchineel tree during a rainstorm is likely to get soaked head to toe in the botanical equivalent of WWI mustard gas. In fact, phorbol is so corrosive it has even been known to peel the paint off of cars.
If ingested, the other toxins in the Manchineel’s sap and fruit can induce severe throat pain and swelling, vomiting, excruciating intestinal pain, psychological disturbances, and even death. Indeed, the tree’s scientific name, Hippomane Mancinella, literally translates to “the little apple that drives horses mad.” Among the many toxins found in the tree, one, physostigmine, is also found in the Calabar bean, which for centuries was used by the Efik people of south-east Nigeria as an ordeal poison. According to Efik custom, a person accused of witchcraft would be made to drink a mixture of crushed-up Calabar bean and water; if they died, they were guilty, but if they survived – usually by immediately vomiting up the poison – they would be declared innocent and released.
If by now your reaction to the big pile of “nope” that is the Manchineel tree is to yell“kill it with fire!” unfortunately you are once again out of luck, as the smoke from burning the tree can inflict severe damage to the eyes and lungs. Point Manchineel tree…
The toxic properties of the Manchineel have been known for centuries, the sap being used as a weapon by many Caribbean tribes such as the Arawak, Taino, Carib, and Calusa. Indeed, it was a Calusa arrow tipped with Manchineel sap which reportedly killed Spanish Conquistador Juan Ponce de Leon during a skirmish in Florida in 1521. There are also reports of tribes tying their enemies to the trees as a form of torture. But not all the tree’s uses were so violent; the dried sap and fruit, for example, are used in traditional medicine to treat edema and urinary issues. And incredibly, despite its dangerous reputation Manchineel wood has also been used for centuries by Caribbean carvers and cabinetmakers. As cutting the trunk with an axe is too dangerous, the tree must instead be burned at the base – with the collector, one assumes, standing far, far away – and the wood dried in the sun for several days to destroy the toxins in the sap.
Among the first Europeans to encounter the Manchineel tree was Christopher Columbus, who gave it its traditional name of “little apple of death” and described its effects on sailors who accidentally ate its fruit or cut down the tree for firewood. The tree was also commonly encountered during the Golden Age of Piracy and appears in the memoirs of many 17th and 18th Century buccaneers such as Basil Ringrose and William Stephens as well as in the diary of William Ellis, the surgeon on Captain James Cook’s last voyage.
At this point you may be wondering: how on earth did the Manchineel evolve to be so horrifically toxic? After all, most fruit-bearing trees depend on their fruit being eaten by animals in order to spread their seeds. But with the sole exception of the Black-Spined Iguana, which is even known to live among the tree’s branches with no ill effects, the Manchineel is toxic to nearly every known animal. As it turns out, the Manchineel has no need of animals as, by virtue of growing near water, its buoyant fruit are easily dispersed by ocean currents in the same manner as coconuts. Thus the tree’s extreme toxicity is likely as it poses no obstacle to its reproduction while ensuring that any potentially destructive animals keep far, far away.
Today the Manchineel is an endangered species, but rather than being exterminated like the demon spawn it is, the tree is protected as its roots help to stabilize the soil and protect shorelines from erosion. Consequently, Manchineel trees in areas accessible to the public are often clearly marked with red paint, small fences, or explicit warning signs to make sure nobody goes anywhere near them. While no deaths from eating Machineel fruit have been confirmed in modern times, dozens of cases of burns and blindness due to contact with its sap are reported every year. So if ever you are on a Caribbean holiday and come across a small tree with reddish bark, spear-shaped leaves, and small yellow-green fruit. Don’t even think about it. Just walk away.
