Some of the 11 highly poisonous plants on earth are all around us.

Plants will grow into a variety of shapes to protect themselves, but some grow very attractive, but they are easy to kill. If you see these plants in the wild, you must go as far as you can, and don't eat them by mistake. Of course, you must understand them first!

1. British yew

It seems that juicy and delicate berries are deceptive because they are one of the most poisonous tree species on earth. This tree has juicy red berries and its seeds are very poisonous.

But this kind of berry is harmless to some birds. For humans, just 50 grams is enough to kill. Eating by mistake can cause convulsions and muscle tremors, which can eventually lead to cardiac arrest.

2. Poisonous ginseng

This poison was widely used to carry out the death penalty in ancient Greece, best known as the great Socrates, who died after drinking wine made from poisonous ginseng.

The poison of poisonous ginseng is called "apigenin", which affects the human body in the nervous aspect and can lead to paralysis. It starts with the legs and moves upward until the respiratory system and muscles are affected, resulting in ingestion and death within minutes. (wild celery picking occurred in our country, and some accidentally ate hemlock.)

3. Oleander

Oleander is a very beautiful courtyard flowering plant, native to Asia, but now spread throughout the Mediterranean and North America.

Accidental ingestion of any part of the plant can cause bloody stools, vomiting and arrhythmia. The whole plant contains a glycoside called cardiotonic glycoside, which can lead to cardiac arrest. Even if the plant is cooked and burned, it releases toxins, and excessive inhalation can harm humans.

4. White snake root grass

A poisonous plant growing in North American grasslands and pastures. When herbivores, such as cattle, eat it, it can cause a disease called tremor, and even the milk that eats the grass is poisonous.

Although this plant is used as a treatment for snake bites, accidental ingestion can cause immediate human death. Can cause vomiting, thirst, and eventually death.

It is widely believed that President Lincoln's mother died because she drank milk from the grass.

5. Poisonous berries (leaf-like cohosh)

Foreigners call it "Doll's eyes". It is a flowering plant native to the eastern United States. This kind of plant looks very strange. There are small black spots on its small white berries, which look like eyes.

The whole plant is poisonous to human beings, and its most dangerous is the fruit. There have been children who have been attracted to eat its berries by mistake, although it tastes sweet, accidentally eating or overtaking the plant can cause sudden cardiac arrest and death, but the toxin is harmless to birds.

PS: there is a red variety, which you should have seen before. It is also quite common in our country.

6. Suicide tree

The suicide tree is native to tropical India and Southeast Asia. This plant is called the sea lemon tree. Its fruit is always used as a suicide poison, hence its name.

Although the fruit has the smell of jasmine, but accidental eating will make the heartbeat chaos, the poet convulsive disease stimulates the nervous system, causing people to die suddenly. (has been used for murder)

7. Poisonous guava

Also known as Euphorbia officinalis, originally in Florida, this tree is highly poisonous, the fruit is like a small apple, can not feel the tongue, the toxicity is very strong. But the fruit is the least toxic part of the tree.

Its juice is the most poisonous, causing blisters, inflammation, swelling and severe pain in one drop.

8. See blood sealing throat (poison arrow wood)

It is one of the most poisonous plant species in the world, and its sap is milky poison. Once the juice enters the bloodstream, it is life-threatening. The ancients often painted it on arrowheads to shoot wild animals or enemies. It can be seen in Hainan and Xishuangbanna Botanical Gardens.

9. Mother Chicken beads (Acacia beans)

Mother chicken beads are one of the deadliest plants known to mankind. Native to Indonesia, the seeds of this plant are bright red and have a black spot on the top. The poisonous protein in the mother bead seed is so deadly that it can kill people by inhaling less than 3 micrograms, and one seed can be fatal. (some people use this seed to process rosary beads, once broken, people will be poisoned, intact is non-toxic, it can be seen that it is highly toxic.)

10. Gut-breaking grass

Scutellaria angustifolia is a plant of the family Cucurbitaceae, which is a kind of wild vine in the south. Its main toxic substance is sinomenine. According to records, after eating, the intestines will become black and adhere, and people will die of abdominal pain.

11. Castor bean

Castor bean contains ricin, which can be poisoned if eaten by mistake. It has a lot of varieties, although some are not toxic, but excessive can also lead to death, 20 adults can die. Two castor beans from Africa can kill adults.

But unexpectedly, its seed is used to make castor oil, and it has a wide range of uses. It was planted at the door before, but I didn't expect it to be so poisonous.

In short, not all plants look so harmless, beware of these poisonous plants, be sure to stay away from them!
