Often called the “Tree of Death,” the Manchineel tree is one of the most poisonous trees in the world. Found in the Caribbean, Central America, and parts of Florida, this tree’s sap contains toxins that can cause severe blisters and burns if it comes into contact with your skin.
Even standing under this tree during rain can be dangerous because the sap can mix with water droplets. Its small, green apple-like fruits may look tempting but are extremely toxic if consumed.
The Suicide Tree (Cerbera odollam)
Native to India and Southeast Asia, the Suicide Tree gets its name from its highly toxic seeds. The seeds contain cerberin, a poison that disrupts heart function, often leading to fatal outcomes.
Sadly, this tree has been used in numerous poisonings, both accidental and intentional. Despite its danger, the tree produces beautiful white flowers that attract attention.
Gympie-Gympie (Dendrocnide moroides)
Known as the “Stinging Tree,” the Gympie-Gympie is native to Australia. It may look like an ordinary bush, but its leaves are covered in tiny, hair-like needles that deliver an intense and long-lasting sting.
The pain can last for weeks or even months. In extreme cases, the sting can cause severe allergic reactions. Even dead leaves remain dangerous, making this tree one to avoid.
Bunya Pine (Araucaria bidwillii)
The Bunya Pine is an ancient tree found in Australia, known for its enormous pinecones.
These cones can weigh up to 22 pounds (10 kilograms) and fall from great heights, posing a serious risk to anyone below. While the seeds are edible and highly valued, standing under a Bunya Pine during cone season can be hazardous.
Sandbox Tree (Hura crepitans)
The Sandbox Tree, also called the “Dynamite Tree,” is native to tropical regions of the Americas. This tree has spiny bark and toxic sap that can cause severe skin irritation and blindness if it gets into the eyes.
The nickname “Dynamite Tree” comes from its explosive seed pods, which burst open with a loud bang, sending seeds flying at high speeds. These flying seeds can cause injuries, making the Sandbox Tree doubly dangerous.
European Yew (Taxus baccata)
The European Yew is an evergreen tree found across Europe and parts of Asia. Almost every part of this tree, except its bright red berries, is highly toxic. The tree contains taxine alkaloids, which can cause nausea, paralysis, and even death if ingested.
While the berries look harmless, even their seeds are poisonous. Despite its danger, the Yew is often planted in gardens for its ornamental value.
Strychnine Tree (Strychnos nux-vomica)
Native to India and Southeast Asia, the Strychnine Tree is infamous for its toxic seeds, which contain strychnine. This powerful poison affects the nervous system, causing painful muscle spasms and respiratory failure.
Historically, it has been used as a poison for both humans and animals. Interestingly, the tree’s bark and seeds have also been used in traditional medicine, but handling it requires extreme caution.
