Deadly plants

Upas Tree

Our world is covered with plants, and we are surrounded by them. There are many poisonous plants.
The best way to avoid accidental poisoning from plants is knowledge and prevention.
No bird flies near, no tiger creeps; alone the whirlwind, wild and black, assails the tree of death and sweeps away with death upon its back.
A. S. Pushkin, The Upas Tree

Malaysian told European visitors about the tree of death. They said that the upas tree killed birds flying over it and that anyone who slept in its shade would never wake up.
Now we know that these stories are untrue. Birds sit unharmed in its branches and sleeping under the tree is safe.
However, the sap of the tree contains a deadly poison. A scratch from the bark causes a painful rash. Local people once executed prisoners by tying them to the tree, or by stabbing them with a stick dipped in the poison.

It the tree were smaller it would look like a candelabra. That’s why it has such a name. The candelabra trees grow in South Africa and may reach the height of a house. Its milky sap can burn your skin and even cause blindness if it gets in your eyes.

The spines of the Mexican ‘hedgehog’ cactus are like daggers. The Aztecs of ancient Mexico had a grisly use for this plant. If one of their gods demanded a gift of human blood, they stretched prisoners across the cactus.

In the depths of the Amazon rainforest native people found the ingredients to make one of the world’s most powerful natural poisons: curare. They used it to hunt animals. To get the poison, they soaked the bark and roots of certain plants in water, then boiled the water to make a paste. They smeared the paste on small darts and shot the darts from long bamboo blowpipes.

Giant Hogweed is truly a plant from nightmares. It is sensitive to light, and produces thick juice, which covers the human skin when you touch the plant. Almost immediately juice reacts with the sun and produces a chemical reaction which burns skin and soft tissues of the human body. This leads to necrosis and the formation of huge wounds that may not heal for a few years. What is the most interesting, pigs have immunity to it.
