The 'tree of life' might be a popular concept in mythology, folklore, or even religious stories, but in the world of biology, there is an existence of veritable trees of death that can cause great harm to humans.
While we aren’t sure about the man-eating tree portrayed in some folklore, all the trees we have considered in this particular account show that truth can be even stranger than fiction.
In this article, we will explore the top 10 dangerous trees we all need to watch out for. While these trees are poisonous to touch or eat—they are used for their other, more practical, properties.

It is nicknamed the Manzanilla de la Muerte—little apple of death—for a reason. The fruit can be potentially fatal, and the milky sap from the tree causes extreme allergic reactions and blisters.
So why do manchineel trees still exist, then? Is there any positive of the manchineel tree?
