First, the poisonous guava tree
The poisonous guava tree was once rated as "the most dangerous tree in the world" by Guinness World Records. Mainly distributed in the Caribbean, southern Florida, South America and other regions, the maximum length can be about 15 meters. This is a kind of tree that is almost poisonous all over.
The trunk and leaves of poisonous guava secrete white juice, which contains an irritating chemical called phorbol. As long as people touch these juices, their skin will have a strong burning sensation and blisters, which is very painful. Even if you don't touch the trunk and hide from the rain under the tree, it may lead to rain with poisonous juice. If you accidentally enter your eyes, it will lead to blindness.
Besides fruit juice, the fruit of guava is also poisonous. This kind of fruit looks like a green apple when it is ripe, and it is sweet when it is eaten at first, but soon, the mouth and esophagus of the consumer will have a strong burning sensation and burn-like blisters. At the same time, it will be accompanied by bleeding, shock and other symptoms, and even lead to death in severe cases, so the poison guava tree is called "dead little apple".
Second, Bunia tree
This is an old tree that grows in Australia. It has lived on the earth since Jurassic, and it has been about 65.438+0.99 billion years. From the appearance, Bunia tree has a unique shape. It is a beautiful tree, which can usually grow to more than 30 meters. But you must not be deceived by its appearance. It is no less dangerous than the poisonous guava tree. The difference is that the danger of Bunia tree is mainly itself.
Bunia trees are covered with hard and sharp leaves. If you get close, you will be easily scratched by these leaves. Even if you want to handle these leaves, you must wear professional protective equipment. However, compared with leaves, the most dangerous thing is its fruit. During February and March of 65438+ every year, Bunia trees will bear a lot of fruits and fall off. Fruit shedding is normal, but the weight of each fruit is about 18 kg.
Think about it, what is the result of a spherical fruit that is heavier than the shot put falling from the ninth floor! Once a man was hit by the fruit of Bunia tree while resting under the tree. 7.3 kilograms of fallen fruit. The man was out of danger after two operations, but it also caused irreversible brain damage.
Third: sandbox tree
Sandbox trees are native to tropical areas of North America and South America. It is a tree full of thorns, and its fruit is comparable to a "bomb". No matter people or animals see it, they will hide far away. It can grow to 30 meters high. Its trunk is covered with dense black spikes, which can grow to 2 cm long and sharp as a dagger. If you touch it with your hands, it will easily become a "hornet's nest".
In addition, the sap of the sandbox tree is corrosive. It is said that local fishermen will poison fish with this juice, and the sandbox tree evolved mainly to protect its fruit, that is, its seeds.
The fruit of the sandbox tree looks like a pumpkin, nothing special, but once the fruit matures and dries, it will explode like a Grenade. When the fruit explodes, it will break into pieces, and the seeds inside will be sprayed to the surrounding area of 30- 100 meters at the speed of 240 kilometers per hour, which is a threat to people and animals around. I believe no one would want to get close to such a dangerous tree.
Fourth: sea lemon tree
Sea lemon tree belongs to a family of Apocynaceae and grows in southwest India. The sea lemon tree will bear a green fruit, which looks like a small mango and is called sea lemon fruit. This kind of fruit contains a toxic chemical, which will make people's heart stop beating slowly after eating, which is similar to a heart attack and can kill people in a short time.
In India, many women commit suicide with sea lemon fruit, so the sea lemon tree is often called "suicide tree". According to the data, there were 537 cases of death due to the poisoning of sea lemon fruit. The most important point is that the medical profession didn't know much about the sea lemon fruit before, and this plant only grows in India, and doctors in many western countries know little about it, so the sea lemon fruit is also regarded as a killing tool by some criminals.
Fifth: Woody Datura stramonium
You can't see how dangerous it is from the outside. The tree is full of beautiful flowers like morning glory, including white, yellow, pink, green and red. It is an ornamental plant, native to South America.
But if you see it, don't try to touch it, because all parts of the woody Datura can be poisonous and dangerous leaves and seeds. Woody Datura contains many toxins such as scopolamine, which will affect people's central nervous system. After ingesting, people will have confusion, rapid heartbeat, auditory hallucinations, auditory hallucinations and even death.
