These dangerous plants are less known than nettles, although many of them burn much more severely. At the same time, they can be found in your favorite park, along the sidewalk along which you walk to work, on the green lawn where you decided to have a picnic.

1. Hogweed Sosnovsky

This giant "dill" with large white inflorescences on thick stems can reach three meters in height. If you see one like this, don't come close.

Contains furanocoumarins, which deprive the skin of ultraviolet protection. Therefore, burns and large blisters appear on the affected areas even under the gentle morning or evening sun. And if the juice gets on the mucous membranes of the eyes, you can go blind.

To be fair, let’s say that there are also non-dangerous species of hogweed. Some of them are even eaten. For example, for preparing borscht, hence the name.

But if you are not a botanist and are not sure that specific umbrellas and the stems with leaves located under them are harmless, it is better not to risk it.

2. Meadow parsnip

This is also an umbrella plant. True, smaller and with faded yellow inflorescences. Parsnip juice and pollen contains Parsnip psoralens are substances that, like furanocoumarins in hogweed, increase skin sensitivity to sunlight. The result is (stripes, spots, rashes, blisters) appearing on the affected area within 24 hours after contact. Parsnips are considered the most dangerous during the flowering period, that is, in July - August.

3. Buttercup

The name sounds gentle, even touching, but this plant is only a flower in appearance (yes, yellow, beautiful). The berries begin after contact.

So it’s absolutely not worth collecting buttercup bouquets and smelling them.

4. Larkspur (delphinium)

This plant is also from the insidious buttercup family, although it seems that its tall, covered with small blue and purple flowers the stems do not resemble buttercups in any way.

When in contact with skin, larkspur sap and pollen can cause irritation, similar to what occurs when coming into contact with stinging nettle.

Sometimes delphinium flowers are bred as. In this case, you can work with them only with gloves, and also keep children and pets away from the flowers.

5. Lumbago (sleep-grass)

Another relative of the seemingly harmless but predatory buttercup. Its juice contains poisonous alkaloids that cause inflammation of the skin and mucous membranes. Therefore, it is advisable to wear gloves when picking such flowers.

6. Poison Oak

This beautiful shrub with almost glossy leaves saturated with juice belongs to the genus of toxicodendrons - “toxic trees”, if this name is literally translated from Latin.

Its leaves and stems contain urushiol oil. Allergies to Poison Ivy, Oak, and Sumac. It irritates the skin and can cause severe allergies - an itchy red rash with bumps and blisters.

According to experts from the American Center for Disease Control and Prevention (CDC), severe reactions even require POISONOUS PLANTS emergency medical care.

7. Poison ivy

The closest relative of poison oak, and its habits are the same. It is easy to distinguish it from other ivy: each poisonous ivy branch ends in three glossy leaves. Depending on the season, the leaves can be either green or beautiful yellow, orange and even red.

8. Yasenets (burning bush)

Ash forms a slender bush with many beautiful inflorescences and is often used as a decoration for gardens. But this spectacular plant is dangerous. When its seeds ripen, a huge amount is released. If you bring a match to a plant, a flame will flare up above it. In this case, the ash tree itself will not be harmed. This curious feature was the reason for the appearance of the second name - the burning bush.

You cannot touch the ash tree without gloves and closed clothing. BURNING BUSH. You won't feel anything right away, but after about a day, burns with blisters may appear on the affected area of ​​skin. Later, the blisters will burst, and scars will remain in their place.

9. Euphorbia

But during the preparation of oil, castor bean fruits undergo powerful steam treatment, which destroys the toxins they contain. But if toxins are not removed, problems may arise.

You can touch the castor bean. But you shouldn’t pick it: if you accidentally damage the skin of the fruit, you may get a dose of ricin. If ingested (for example, from poorly washed hands), this substance may cause A Case of Castor Bean Poisoning to the development of gastroenteritis, including death. Additional side effects- neurological disorders and damage to the mucous membranes of the eyes.

How to make sure that you have a poisonous plant in front of you

It is quite difficult to distinguish a dangerous plant from a safe one. Often, only a professional botanist can cope with this task. Therefore, there is only one piece of advice: if in doubt, it is better not to approach.

Bookworms can use the PlantNet app. Just take a photo of the plant, indicate your location (to speed up the search) - and get the most likely name of your flower.

What to do if you touch a poisonous plant

1. Rinse your skin as quickly as possible with running water or at least wipe with a damp cloth.
2. Apply an antihistamine cream to the affected area to reduce symptoms of irritation.
3. Accept antihistamine. Any will do, just follow the instructions carefully.
4. If we are talking about contact with plants that increase skin sensitivity to sunlight, try to hide from the sun over the next few days: spend more time indoors and wear long sleeves.

It is difficult to imagine how many mysteries the Russian land conceals, and how many dangers it conceals is even more difficult to imagine. We will talk about the most dangerous and poisonous plants growing in Russia.

In fact, plant poison, if collected on a mass scale, could partially replace chemical and biological weapons... and even simple weapons in some cases. There are stories when dedicated people used plant poisons for inhumane, selfish purposes, for example, eliminating an enemy.

IN Ancient Greece With the help of hemlock juice (a plant which, by the way, is quite common in Russia), death sentences were carried out. Socrates, according to available information, was sent to the Other World with the help of hemlock juice, according to other sources - spotted hemlock. Both plants live happily in Russia.

As legends say, before, when villages were captured by enemies, Russians fleeing to save their lives poured juices into barrels of wine and juices stored in cellars. poisonous plants- belladonna, henbane, etc.

Many herbs have healing properties, but there are those that can bring not only healing, but also death. The paradox is that almost all poisonous plants are used for the preparation of medicines along with useful ones, only the raw materials are carefully dosed.

As they say (the words of Paracelsus, genius doctor of all times and peoples): “Only the dose makes a substance a poison or a medicine.”

Very often, the juices and raw materials of poisonous plants are used to treat the heart, stop bleeding, and relieve pain.

Potato juice (and also the juices of various vegetables, berries: sorrel, currants, beets, cucumber, cabbage, cranberries), beaten egg white with raw milk, powder from dried orchis tubers, valerian root, elecampane root.

In total, about 10 thousand poisonous plants are known in the world, many of them grow in the tropics and subtropics, but on Russian soil, flowers and greens are found almost all the time, capable of causing harm to humans under certain conditions. It’s just that we don’t eat or pick up all the plants – this saves us from the consequences. However, when visiting the forest, especially with children, you should not forget how much danger can lurk among the grass, because it is children who often suffer from plant poisons.

Let's look at the most common poisonous plants in Russia.

When taking hemlock juice in non-lethal doses (up to 100 grams of rhizome), symptoms of intestinal poisoning begin within a few minutes, then foam at the mouth, unsteady gait, and dizziness. When taking higher doses - convulsions leading to paralysis and death.

Even the smoke from burning plant leaves is dangerous.

In ancient times, when there were no pistols and modern technologies, natural poisons were used with might and main to eliminate enemies. They lubricated the tips of bow arrows with the juice of poisonous plants, which guaranteed the death of the enemy, and they actively used the same aconite.

Poisonous plants actually grow everywhere in Russia. Their danger lies mainly not in the fact that they grow everywhere - after all, people do not eat them en masse - but in the fact that they are similar to others, edible, and in the fact that many are beautiful: for example, they are simply confused with useful plants, which is fraught.

Since primitive times, man has been using various plants: at first he only ate them, then he learned to make fabrics, paper, houses, ships from them, and having understood them healing properties, began to isolate from them physiologically active substances for the production of effective medicines.
Of course, not all plants are beneficial to humans. They constitute a large kingdom of living organisms that have been adapting to constantly changing conditions for hundreds of millions of years. environment. Some of the abilities of plants surprise and amaze us - their use of toxic substances, sharp thorns and even digestive juice, which helps cope with insects and even larger representatives of the animal world. There are many types of plants that can harm humans, and some of them can even kill them. What are the top 10 most dangerous plants in the world?

On our planet there are a wide variety of dangerous places, which have recently begun to attract a special category of extreme tourists looking for...

1. Castor bean

From castor beans, people obtain the well-known castor oil, which has long been widely used in medicine as an analgesic and antiviral agent that helps in the treatment of skin diseases. But the castor bean was included in the Guinness Book of Records as the most poisonous plant.
Castor bean grows in Egypt, China, Iran, Brazil, Argentina, where it reaches a decent height of 10 meters, and in a temperate climate, like ours, it is much shorter. It is often grown as a very beautiful ornamental plant with reddish carved leaves. In the shells of its beautiful seeds, castor beans contain the strongest protein poison - ricin, and in all other parts of the plant there is another toxin - the alkaloid ricinin. Ricin is approximately 5-6 times more toxic than the “classic” poison - potassium cyanide.
In fact, it is not so easy to get poisoned from castor beans - to do this you need to eat a handful of seeds that resemble beans. An adult is unlikely to do this, but children sometimes fall for the beautiful “grillage” and almost certainly become its victims. Signs of ricin poisoning appear after a long pause (sometimes more than a day), and then resemble food poisoning. Treatment for ricin poisoning is conditional because there is no antidote and the mortality rate is very high.

2. Manzinella

Belonging to the euphorbia family, the manchinella tree (also known as manchinilla, manzinella) is one of the most poisonous plants on earth. It grows in Central America. The fruits of this beautiful plant have the affectionate name “apples of death”. The fruits, which look like small greenish-yellow apples, are so poisonous that after taking a few bites from them, a person can quickly go to his ancestors. The milky juice of these fruits causes severe distress digestive system, accompanied by vomiting, and then some organs fail and the person dies.
However, not only the fruits, but also the rest of the manchinella are poisonous because they contain phorbol. Even just touching a tree trunk is enough to cause an allergic rash to appear on the skin. If the poison penetrates the body, then death is inevitable. If the plant juice gets into the eyes, the person may go blind. It’s better not even to escape the rain by standing under the crown of a manchinella tree, since the water flowing down it already becomes poisonous. But the honey obtained from manchinella flowers is considered a great delicacy.

3. Ongaonga (nettle tree)

This endemic species living in New Zealand is also called the “ferocious nettle”. But the native nettle has a woody trunk, and on the leaves and the trunk itself there are thousands of sharp spines with a mixture of formic acid and histamine. This New Zealand nettle grows up to 5 meters. The slightest touch to this plant is enough to cause a very painful burn. Therefore, people and animals need to stay away from the ongaonga. There is at least one known case of a person dying from the “tender embrace” of this inhospitable plant, which affects the nervous system of the victim, who dies from respiratory paralysis.

Ancient people naively mistook volcanic eruptions for the wrath of the gods, however, many people still think so today. But the enlightened part of humanity has long understood...

4. Strychnos poisonous

This tree-like South American vine contains one of the most powerful plant poisons. The vine produces small green juicy fruits. The Indians long ago discovered the secret of this plant and began to use its juice for hunting and war, lubricating the tips of their arrows or darts with it. The strongest alkaloid alpha-tubocurarine is the active ingredient of this plant toxin. It paralyzes the acetylcholine receptors of the striated muscles, that is, it paralyzes the respiratory function of the body, and a person who receives even a minor scratch from a poisoned arrow can die from suffocation, while remaining fully conscious. If the dose of poison is not too large, then the victim can be saved by performing artificial respiration until the kidneys remove the poison from the body. This poison has found quite wide application in medicine.

5. Belladonna

A rather remarkable plant, belladonna or belladonna, also has less romantic names - crazy berry or crazy cherry. It grows in our middle lane, as well as in western Asia and North Africa. Its berries contain alkaloids from the atropine group, which can cause hallucinations and delusions in humans. The very first symptoms of belladonna poisoning are dry mouth, difficulty breathing, loss of voice, headache and convulsions.
The bush has beautiful blue-purple berries, the size of cherries and sweet in taste. But if you eat a dozen of these berries, you can say goodbye to life. The venom of belladonna greatly dilates the pupils, so in the past, beauties often dropped it into their eyes to give them a special shine, and rubbed the berries on their cheeks to give them a blush. A set of belladonna toxins are aimed at blocking the functioning of the nervous system, so they are used as an anticholinergic agent in the treatment of muscle spasms, asthma and excessive sweating.
The whole plant is poisonous, but most of all its leaves, which contain the alkaloid atropine. Children often mistake beautiful belladonna berries for blueberries or blueberries. When poisoned, a person’s vision becomes blurred, pupils dilate, headaches, hallucinations occur, balance is lost, and urine is not drained.

1. (common name). This plant is in large quantities grows in cities, and not just in nature. Despite the fact that it is constantly mowed down and destroyed, its numbers only increase every year.

Gifts of nature such as flowers and plants decorate our lives, making the world around us more vibrant and interesting. Beautiful magnolias, graceful lotuses or passionate roses - these and many other flowers have become an integral part of our everyday life.

However, in addition to the charming aroma, external beauty and useful properties, there are also plants that are harmful to every living creature, even in small quantities. These are exactly what we will be talking about in our rating. Getting to know them will certainly help you in the future. Knowing what they look like can save your life if you ever come across these plants.

The family of these plants is very large and includes more than thirty species, however, the most common types you probably know are the famous “poison ivy” and “poison oak”.

The chance of stumbling upon such trees is great, mainly in different parts of America and Asia. They contain urushiol oil, and it can cause a fairly serious allergic reaction in humans.

The history of the origin of names for these plants is also interesting. Most often, plants were named for their allergic properties and phenotypic similarity with other plants or trees that are not related to them. For example, poison oak is not actually a tree at all, but is only named so because its leaves are similar to those of white oak.

You can come across this herbaceous plant throughout almost the entire European territory and temperate parts of Asia. It prefers rocky places, bushes and calcareous soil.

The oils contained in this plant can pose an immediate danger to people. Upon contact with skin, they can cause severe chemical burns that heal rather slowly. Therefore, you cannot smell the ash tree, much less touch it.

Despite this danger, the plant is often used in ornamental gardening. Ash tree is unpretentious to conditions, has a pleasant aroma and its flowering lasts for quite a long period of time.

There are more than forty-two species of this plant, which are widespread in the Eastern Hemisphere, or more precisely, in its temperate zone. Some of them are used as livestock feed, some are suitable for human food, and some simply serve as ornamental plants.

But other types of it contain special substances that cause severe photochemical burns in humans. Their peculiarity is that as long as the area of ​​​​the skin on which the hogweed juice has fallen is in the shade, nothing will happen to it.

But as soon as the wound is touched sun rays, a very severe and painful burn will immediately appear.

You can stumble upon it mainly in the Siberian forest, or in those located in Central Europe.

The plant is interesting because it is completely poisonous. Berries and rhizomes are especially dangerous, because the substance contained in them causes symptoms in humans such as nausea, cramps, vomiting, and in especially severe cases it can lead to paralysis of the respiratory tract.

Despite increased level poison content in the plant, its berries and leaves are often used in folk medicine, however, in dried form.

Datura is a fairly large herb of the nightshade family. Its genus has thirteen species, which can be found throughout such zones as temperate and steppe.

Even mild dope poisoning can cause speech impairment, delirium, and hallucinations. In severe cases, convulsions may occur, which will lead to loss of consciousness. Comatose states in humans, as well as paralysis of the respiratory tract, are also common.

Since Datura is a hallucinogen, it is often used in folk medicine, and previously in witchcraft rituals. Several centuries ago he also played important role in many religions.

The danger of this plant begins immediately with its appearance. The problem is that hemlock is very easy to confuse with another plant - angelica, which is edible. Therefore, you need to be very careful. If you make a mistake, the consequences can be dire, since hemlock is one of the most poisonous plants on the planet.

It is also insidious because of its aroma - pleasant, reminiscent of carrots, and the taste of the rhizome - radish. However, do not forget that just one hundred grams of rhizome is enough to kill a whole cow.

If a person tries hemlock, then within just a few minutes the first terrible symptoms will appear: nausea, vomiting, abdominal pain, and then possible dizziness and foam at the mouth. The victim's pupils will always be dilated, and there is a high probability that seizures and convulsions will result in death.

Hemlock can be found in Eastern and Western Europe and in the northern regions of Asia.
