Perhaps, reading this article, many will ask the question - why, in fact, do we need poisonous plants?

There are no superfluous links in nature: it is unique and well thought out. The poisonous properties of certain plant species are a disadvantage for humans, while for the plants themselves it is the ability to evolve. Growth, survival, the ability to adapt to changing conditions - all this many plants owe precisely to their toxicity.

In addition, over time, a person nevertheless learned to use the harmful properties of many herbs, flowers and berries for his own good. An example of this is a huge number of medicines based on poisonous plants.

Poisonous plants of Russia

Summer is coming, wonderful time. But even in summer we should be careful with the gifts of nature. This also applies to children and those who are alone with nature for a long time. It is possible to hold out in the wild without food supplies until help arrives or you yourself come across some settlement, if you switch to pasture. From spring to autumn, finding it in the forest will not be difficult. But no matter how delicious the gifts of nature may seem, there is everything in a row, in no case is it possible. There are such wild berries, which, at best, can get rid of food poisoning, and at worst, everything will end in death.

Belladonna (lat.Atr? Pa bellad? Nna)

This herbaceous plant reaches a height of 2 meters, the stems are branched and thick with large leaves, the flowers are small, bell-shaped, usually next to them you can find small black-purple berries.

WHERE? The easiest way to find Belladonna is in the Crimea, the Caucasus and in the regions of Russia bordering on Western Ukraine (no politics, pure botany), where it grows on forest edges, clearings, and river banks.
AS ? The alkaloids atropine and hyoscyamine included in its composition can cause a person's strong excitement, reaching madness, loss of orientation in space, accompanied by delirium and hallucinations. A person who decides to try belladonna will feel a decrease in vision, dry skin, and an increase in body temperature. Death is also possible.

A relative of belladonna, they both belong to the “nightshade” family, they are also visually similar, but the henbane is lower, its stems are thicker and covered with villi. Apparently, due to its less attractiveness, henbane is also more poisonous.

WHERE? It grows almost everywhere in Russia, and not far from a person: along roadsides, in courtyards of houses, in vegetable gardens.

AS ? In addition to atropine and hoiscyamine, it also contains scopolamine. All three make the henbane one of the most dangerous members of the family, the poison is found in all parts of the plant, and especially in the seeds. Its action causes fever, increased heart rate, confusion, dry mouth and impaired vision. Moreover, the first symptoms appear less than half an hour after the henbane enters the body.

Not only the brain goes crazy, but also the gastrointestinal tract: enteritis, vomiting, colic, internal bleeding ... After eating seeds or other parts of castor beans, symptoms appear within about an hour, death occurs in 5-7 days.

Ash (Latin Dict? Mnus) - burning bush

The fruits of this plant contain a large amount of essential oils, so when rubbed, ash gives off a delicate scent of lemon, which can seem very attractive to those who do not know what this aromatherapy leads to.

WHERE? It is found in the southern part of the country from Smolensk to Blagoveshchensk in rocky places, non-acidic soil, among bushes.

AS ? Within a day after touching or even approaching (you just can't smell it either), severe burns may appear at the point of contact, subsequently becoming covered with blisters, ulcers and turning into scars over time. If more than 80% of the skin is affected by ash, death is possible.

Spotted hemlock (Latin Con? Um macul? Tum)

The plant is about a meter high, with long hollow stems, it looks empty and simple, as inconspicuous as many of the above. It is used in folk medicine as a sedative, anticonvulsant and pain reliever, but it can also be used to make poison.

AS ? The main toxic substance of Hemlock spotted is konyin, it has a nicotine-like and curariform effect. As soon as it enters the body, it causes agitation, and then respiratory arrest.

Vyokh poisonous (lat.Cic? Ta vir? Sa)

Its other names - water rabies, water hemlock, mutton and gorigolov - already speak volumes. Although the killer looks inconspicuous: thin stems, white flower umbrellas, it is rather difficult to distinguish it from safe umbrella plants.

WHERE? Distributed in Europe and the European part of Russia.

AS ? The whole plant is poisonous, but the largest concentration of harmful substances falls on the root, it tastes like rutabaga or radish. Just 100 grams of this radish is enough to kill a cow. This action provides the content of the poison cicutoxin, which causes death through a disorder of the central nervous system. A few minutes are enough for the first symptoms to appear: nausea, colic in the lower abdomen, dizziness, foam at the mouth, convulsions and paralysis.

Under this name, about twenty species of umbrella plants are united, visually (and not only) similar to the poisonous one. But unlike veh, some of the omezhniks are used as spices, the main thing here is not to confuse saffron omezhnik with water omezhnik.

WHERE? It grows in temperate climates, different species choose different places, water omelet, for example, in the floodplains of rivers, partially submerged in water.

AS ? The neurotoxins contained in the poisonous species of the omelet are very similar to cicutoxin vech, so look up and re-read the previous paragraph about nausea, froth at the mouth, suffering and pain.

Four-leafed raven eye (Latin P? Ris quadrif? Lia)

WHERE? In mixed, deciduous and coniferous, that is, in almost all forests of Russia, it is found in ravines, shady and humid secluded places.
