Manchineel Tree: The World's Most Dangerous Tree

The video discusses the Manchineel tree, known as the world's most dangerous tree due to its toxic properties. Found in regions from northern South America to Florida, every part of the tree is harmful, with phorbols being the primary toxins. These toxins can cause severe health issues, including blindness and intestinal damage. Despite its toxicity, the Manchineel tree plays a crucial ecological role by protecting coastlines and providing habitat for certain reptiles. Humans have also found uses for its hard wood, though it requires careful handling. The video concludes with a call to support SciShow on Patreon.
