What is the world's most poisonous plant?

The world's most poisonous plant is Dendrocnide moroides, commonly known as the Gympie-Gympie or stinging tree. This plant is native to the rainforests of eastern Australia and can cause severe pain to anyone who comes in contact with it. The plant's leaves and stems are covered in tiny needle-like hairs that can break off and inject a potent neurotoxin into the skin.

The effects of the toxin can last for months or even years, causing intense pain, swelling, and even paralysis. The pain has been described as feeling like being stung by a thousand bees at once, and in severe cases, can lead to hospitalization or even death.

While Dendrocnide moroides is considered the most poisonous plant in the world, there are many other plants that contain toxic compounds and can be harmful to humans or animals if ingested or touched. It's important to always exercise caution when handling unknown plants and to seek medical attention immediately if you experience any adverse symptoms after coming into contact with a plant.
