The earth is extremely rich in biological species. There are about 400,000 species of plants alone, and among plants, there are 60,065 species of trees. Among these tens of thousands of trees, there are five trees that are called the most dangerous trees in the world. One of them is called the sandbox tree. It is covered with thorns. Not only does no one dare to touch it, but its fruits will also cause damage. Explosion is extremely harmful. Why is the

sandbox tree covered with thorns? Does its fruit explode when touched, or does it take time to explode? How powerful is it? Besides the sandbox tree, what are the other four most dangerous trees in the world? What are the dangers they pose? Can the danger be eliminated artificially?

Exploding Sandbox Tree

The sandbox tree is a tree in the tropical rain forests of North America. It likes to grow in moist sandy soil and can grow up to 60 meters . The trunk is densely covered with sharp thorns and the leaves Oval in shape. In the past, when people used parchment to write, they needed to use ink-absorbing powder to prevent the writing from blurring. But at that time, powdery items were not easy to store. By chance, people discovered the fruit of the tree . , can save absorber , people began to use it to save absorber, and named the sandbox tree.

Many Euphorbiaceae plants are poisonous, such as keel,autumn maple, and poinsettia, and the sandbox tree also belongs to the Euphorbiaceae plant, and its fruits and sap are poisonous.

Some trees are full of treasures, and some trees are full of poison. The sandbox tree belongs to the second type: full of poison. The sap of the tree is poisonous. Simply touching the skin will cause rash . If it accidentally gets into the eyes, severe cases can directly lead to blindness. The thorns on the sandbox tree are also toxic. The thorns are not only sharp and can hurt the skin, but also bring their toxicity into the skin. Also, because the sandbox tree is covered with thorns and poisonous, even monkeys dare not Climbing, therefore, is also called "monkeys don't crawl".

The most dangerous thing about the sandbox tree is its fruit. The fruit of the sandbox tree also contains toxins. After eating, it will cause diarrhea, lead to dehydration, and in severe cases, death.. In the early days, some indigenous people in South America would smear the sap of the sandbox tree on their arrowheads and darts to make poisonous curare darts for fighting.

Other plants may be avoided by people because they are poisonous, but the biggest damage caused by the sandbox tree is the explosion of its fruits. The explosive power of the sandbox tree is very powerful. Although its fruits look like small pumpkins , they look harmless. If you touch them when they are immature, they will not be poisonous or cause the fruits to explode. But once the fruit matures, the sandbox tree will spread the fruit by explosion.

Each mature fruit of the sandbox tree is like a small cannonball, with a range of tens or even hundreds of meters. After being shot, these fruits can be firmly fixed in one place, and their power is greater than that of early pistols. The power is still strong.

Although the fruit of the sandbox tree explodes during the fruit ripe season, in order to protect your own safety, you should stay away from the sandbox tree when you encounter it. We know the dangers of the

sandbox tree, but what are the other four trees that are called the most dangerous trees in the world? How dangerous is it? How much harm will it cause to humans?

The four most dangerous trees in the world

In addition to the sandbox tree, the other four most dangerous trees are poison arrow tree, sea lemon tree , poisonous guava tree and golden bark tree .

The poison arrow tree is also known as "blood seals the throat". Its bark, branches and latex contain toxin . In ancient times, some people coated arrowheads with the sap of the poisonous arrow tree. After shooting a person, the poison quickly spread in the body. The reason why the poisonous arrow tree is called "blood seals the throat" is because it is so toxic that as long as the sap enters the human body, one will definitely die within two hours.

Poison arrow tree is one of the most poisonous trees in the woody plants in the world. It is a genus of MoraceaeSynthetic arrow tree. There are 4 species of plants in this genus, which usually grow in Africa and Asia. of tropical areas.Although there are also plants of the genus Xenophyllum in my country, they are rare, with only one species, and they mostly grow in Yunnan, Guangdong, Guangxi and other places.

In addition, although the poison arrow tree is poisonous, it is also very dangerous. As tropical forests are mined, its number is gradually decreasing. In our country, the poison arrow tree is a national third-level protected plant. The poison arrow tree is a plant with dual functions. It is highly poisonous itself but can also be used as medicine. Although its white juice can seal blood vessels and cause people to suffocate and die, the blood-seeking and throat-sealing second ingredient in its venom has the effect of strengthening the heart, accelerating heart rate, and increasing cardiac blood output. Therefore, compared to other poisonous trees, the medicinal research value of the poison arrow tree is also very great.

The sea lemon tree is known as the plant "killer" . In India, the fruit of the sea lemon tree is often used as a suicide tool, so it is also called the "suicide tree" . Generally, the sea lemon tree can grow up to 15 meters high. The fruit is green, and because it looks very much like a small mango, it is often mistaken for a mango and eaten by people. After being poisoned by eating sea lemon fruit, if immediate treatment is not provided, the poisoned person will die within 3-6 hours.

In India, there are many cases of sea lemon tree poisoning. In the ten years from 1989 to 1999, there were as many as 537 recorded cases of poisoning. In addition, because the sea lemon tree is only distributed in parts of southwestern India, at the stage when medical technology was backward, people died of poisoning after eating it by mistake, and some doctors could not even find the cause of the poisoning. For this reason, the sea lemon tree is considered one of the most dangerous plants in the world.

The reason why the sea lemon tree is poisonous is because its fruit contains a substance called sea mango toxin . This toxin can stop the human heart beating , and its clinical manifestations are very similar to a heart attack. , Therefore, some doctors who do not know about sea mango toxins may also make medical misjudgments.

The poisonous guava tree, like the sandbox tree, is a tree plant of the Euphorbiaceae family. Because its sap can cause leprosy-like symptoms on the skin, it is also known as " Horsecrazy Euphorbia " . This kind does not exist in our country, and it is mostly distributed in the Neotropics. The fruit of the poisonous guava tree is generally the size of a walnut. Because its shape is similar to that of an unripe pomegranate, it is called "poisonous guava".

The fruit of the poisonous guava tree, will have a hint of sweetness in your mouth, , but its severe toxicity is also spread in the sweetness. The danger of the poisonous guava tree is not just as simple as being poisoned after eating it. After its branches are burned, the smoke produced is also toxic. After the eyes are smoked by the smoke, it can cause eye inflammation in mild cases and temporary blindness in severe cases.

Regarding the poisonous guava tree, it should also be noted that you must not take shelter under the poisonous guava tree on rainy days, because the rainwater dripping from the poisonous guava branches and leaves is also toxic, when the water drops fall on it On the skin, it will not only cause a burning sensation, but may even cause blistering. In severe cases, the toxins will burn the skin through rainwater and then penetrate into the body. If not treated in time, it may lead to death. Therefore, the poisonous The pomegranate tree is also known as the "Tree of Death".

However, although the poisonous guava tree is poisonous, the texture of the tree is fine and shows a yellowish brown color. After removing the toxicity from the tree, it can be used to make furniture . Because its rhizomes grow vigorously and mostly grow along the coast, the poisonous guava tree also has the function of windproof and sand-fixing. It can prevent the coastline from being eroded, and its ecological value is very valuable.

The last one, one of the most poisonous trees in the world, is the golden bark tree. The Golden Bark Tree is usually only one or two meters tall, and its fruits are usually purple or pink . Compared to the other most dangerous trees, it looks petite, but the Golden Bark Tree is definitely not weaker than any poisonous tree, even Because its toxicity is so powerful, it has become the most hated tree in the world.

In addition to the rhizomes, leaves, branches and fruits that go deep into the ground, the golden bark tree is densely covered with small burrs. These small burrs contain toxins. Once they penetrate the skin, they will immediately release the toxin . Although being stung by these small burrs may seem very insignificant, because these small burrs are very small, they are difficult to remove once they penetrate the skin, and they contain silica toxins that penetrate into the body and cannot be removed by the human body. When decomposing , the pain caused by it will return to over and over again and continue to .

If you are pricked by a small burr of the golden bark tree, you will only feel the pain caused by the toxin of the small burr, but if you accidentally eat it, the consequences will be more serious. Someone once described the toxicity of the golden bark tree like this: A horse only ate a trace amount of the leaves of the golden bark tree and was poisoned to death . It goes without saying how strong a horse is, but what if it was eaten by a human?

Of course, if it simply causes pain or death, there are so many poisonous trees in the world, and the golden bark tree is not enough to make people hate it so much. And it has become the most hated tree by humans, because in 1968, the British military used it to make chemical weapons and put it on the battlefield. Later, researchers proposed moroidin toxins and goldpipsin, which could eliminate these two toxins. In addition, many researchers believe that the golden bark tree also contains many other toxins.

Finally, the editor believes that the above are only the five most dangerous trees in the world, and there are many poisonous plants and trees that we don’t know. Therefore, we need to stay away from the poisonous trees we know and take a detour. The plants we know also need to be like this in order to truly avoid danger.
