How to make poison at home. Poisons that do not leave behind. How to make poisons at home. Dangerous poisons for animals

Many doctors know how to poison a person at home and how to avoid suspicious signs, however, such an act is criminally punishable. Nevertheless, today some people resort to this method in order to eliminate a rival, often this happens in criminal communities.

Natural products are dangerous if you know what can poison a person. Death is influenced not only by pathogens, but also by compounds. A well-known poison is botulinum toxin, which is produced by special microbes that can multiply intensively in a protein environment. It is the cause of intoxication after eating spoiled canned food, mushrooms and other foods. In the digestive tract, this toxin is not destroyed by enzymes and is absorbed into the mucous membranes of the stomach and intestines.

Persons who choose what to poison a person to death rarely choose botulinum toxin, since death in this case is rare.

However, signs of illness can always be attributed to the last meal, during which canned goods, sausage and other unsafe foods were consumed. Symptoms of poisoning are nausea, vomiting and dry skin, followed by paralysis of the striated muscles.

Most people are familiar with castor oil, but few are aware of ricin, a toxin found in castor bean seeds. Criminals looking for something to quietly poison a person often settle on this poison. It is odorless white crystals that dissolve in liquid, however, when the aqueous solution is boiled, the dangerous properties of ricin disappear.

The toxic substance does not penetrate the skin; it acts only when it enters the body. In case of ricin poisoning, the latent period of intoxication varies from 15 to 24 hours, sometimes symptoms appear earlier. Thus, intestinal colic, bloody diarrhea, nausea and vomiting are detected, and hemorrhages occur on the retina.

If a significant portion of castor bean seeds enters the body, death occurs after 6 days due to damage to internal organs, as well as extensive bleeding.

This poison is sometimes chosen by attackers who think about how they can quickly poison a person. However, death is rare.

The poison of the toadstool was known to medieval politicians and healers, who knew how to poison a person to death. Today, scientists have found that the mushroom contains toxins such as phalloidins and alpha-amanitins, which act quickly and irreversibly; these substances are not destroyed by heat treatment.

The latent period without alarming signs lasts up to 40 hours before the poison enters the blood in large quantities and causes depressing signs of poisoning. It is characterized by diarrhea, vomiting and dehydration, as well as pale skin and increased heart rate. After a few days, extensive damage to the internal organs - the liver and kidneys - occurs, toxic hepatitis develops, after which death is declared.

How can you poison a person, if you do not take into account the above-mentioned means? The following components are used for this purpose:

• atropine;
• solanine;
• aflatoxin.

Atropine is a substance from the group of alkaloids, found in plants - belladonna, datura, henbane and others. Intoxication occurs 1 hour after taking the poison; the degree of poisoning may vary.

Atropine is known to affect the structure of the brain, causing loss of coordination and damage to the heart and lungs. Death occurs infrequently due to an insufficient dose of toxin.

How to briefly poison a person? In this case, the solanine found in root vegetables is a suitable option. It can be found not only in potatoes, but also in tomatoes and eggplants.

Intoxication manifests itself in the form of nausea, vomiting, cramping pain in the abdomen and a feeling of bitterness in the mouth. However, it is unlikely to consume a large dose of solanine, which is why the victims are not in danger of death.

In addition, aflatoxins are a common method of poisoning - a group of toxic substances secreted by a microscopic fungus. If stored improperly, it affects various food products, for example, dried fruits, milk, rice, tea and much more.

The poison in large quantities causes the death of liver cells, however, the poisoning passes without serious consequences and is limited to a temporary deterioration in health

In the old days, people knew the best way to poison a person. This can be easily done with the help of ordinary mercury; the dangerous metal causes fatigue, headaches, and memory loss. In addition, there is an increase in body temperature and a decrease in blood pressure. The digestive system also suffers, and diarrhea and a metallic taste in the mouth are often observed. When a significant amount of mercury vapor is inhaled, death is inevitable, which is why this drug has been a weapon for centuries for criminals who understood how to poison a person without any trace of a crime.

Castor bean is an annual bushy plant. The height of the stems reaches two and even three meters, their color is varied - green, red, brownish. The leaves are large, pinnate, green, located alternately on the stem on long petioles. Castor bean blooms with beautiful small flowers collected in racemose inflorescences.
The fruits look like a red spherical box with thorns. The box contains seeds; in appearance they resemble ticks, which is where the plant got its name. Castor bean looks beautiful, grows quickly and is often used as an ornamental plant in landscape design. In addition, it is grown as an agricultural crop to obtain castor oil. It is produced by cold pressing, as a result of which all hazardous substances remain in the cake.

In addition to castor oil and proteins, castor bean seeds contain ricin. This is a high molecular weight protein compound classified as a natural toxin. Its seeds may contain up to 3%, as well as from 0.1 to 1% of an alkaloid with a similar effect - ricinin. Next, let’s combine them under the general name “ricin.” The plant contains these poisons in small quantities in its leaves and shoots, but for clinical cases of poisoning only the seeds are important.

Effect of ricin

Ricin poisoning develops after ingestion of very small doses. Thus, the lethal dose for humans is 0.003 mg of pure substance per kg of weight, which corresponds to eating 6 castor bean seeds for children and 20 for adults. When administered intramuscularly under experimental conditions, the lethal dose for mice is 0.0075 mg/kg, for cats 0.0002 mg/kg, for dogs 0.0006 mg/kg.

Properties of ricin in its pure form:

The poison does not penetrate the skin; it acts only when ingested or through injection. Cases of castor bean poisoning occur quite often, so the toxic properties of the poison have been well studied. In laboratories, ricin is used to provoke cancer in experimental animals.

The effect of ricin occurs at the cellular level. Penetrating into cellular structures - ribosomes, the toxin disrupts protein synthesis and, accordingly, the functioning of the cell as a whole. A curious property of ricin has been proven - by splitting into subunits, it can form bonds with molecules of other toxins or polypeptides, resulting in a new toxic compound not found in nature.

Symptoms of Ricin Poisoning

In cases of ricin poisoning, symptoms develop within 15 to 24 hours. If poisoning occurred by inhaling a toxin, then signs may appear earlier - after 4–8 hours. In an allergic reaction, symptoms develop immediately after contact with the poison.

Primary symptoms:

A characteristic sign of ricin poisoning is hemorrhages (bleeding) on ​​the retina of the eye.

In severe cases, the following symptoms develop:

• convulsions;
• cyanosis;
• collapse (sharp drop in blood pressure);
• prostration.

Death occurs after 6–8 days due to severe damage to the liver and spleen, extensive hemorrhages in the stomach and intestines, and toxic kidney dystrophy. The pancreas is severely affected. Red blood cells, hemoglobin, protein and cylindrical cells appear in the urine. Characteristic changes are found in the lymph nodes of the abdominal cavity.

When it comes into contact with the skin, ricin does not have any negative effects. After contact of ricin powder with mucous membranes, burning, redness, watering or stinging in the eyes is possible. You should consider the possibility of poison getting ingested, for example, if it was left on your hands and then you ate or smoked.

Poisoning by inhalation does not occur under practical conditions. The situation was recreated in laboratory conditions, and the size of the aerosol particles must be of a certain size - too large droplets settle in the upper respiratory tract, small ones come out back with exhaled air.

First aid and treatment

There is no antidote for ricin. In case of poisoning with this toxin, general measures should be taken to prevent further absorption of the poison and the victim should be immediately taken to the hospital.

First aid is provided as follows.

1. Give 2-4 glasses of water with a suspension of activated carbon to drink.
2. Take a mucous solution inside - rice or flaxseed broth, starch, jelly.
3. Give 5-15 grams of sodium bicarbonate (baking soda) to support the kidneys.

In the hospital, the victim’s stomach is washed with a solution containing a suspension of activated carbon.

In addition to the fact that there is no antidote for ricin, this substance has a large molecule size and, therefore, is poorly excreted by the kidneys. Standard methods of cleansing the body - forced diuresis and hemodialysis - are ineffective in case of poisoning with castor bean seeds. Measures are taken to remove poison from the intestines, symptomatic and supportive treatment:

• restore blood pressure;
• alkalinization of urine is carried out to prevent precipitation of hemoglobin in the kidneys;
• Enveloping drugs are given orally to take;
• laxatives (magnesia) and deep enemas to cleanse the intestines;
• blood transfusion;
• for severe pain, morphine is administered together with atropine.

What is ricin?

In the courtyards of private homes, you can sometimes see a tall plant with large leaves, somewhat similar to maple leaves, and red balls containing seeds. Castor beans are often used for decorative purposes; they grow well and quickly. The plant received its name due to the similarity in appearance of the seeds with mites.

In agriculture, castor oil (ricin oleum) is obtained from castor bean seeds, so it is grown in large quantities. By the way, on sale you can sometimes find “Zinc ricin” ointment with castor oil, which is used for dry dermatoses.

However, few people know that in addition to its benefits, this plant can cause quite serious harm to the human body. Its seeds contain poison - ricin. This substance is present in all parts of the plant, but the seeds are the most dangerous.

The chemical production of ricin comes from castor bean cake. The result is a powdery substance that is white in color. There is no smell. In modern science, it is possible to produce poison in the form of crystals. The compound has good solubility in aqueous solutions. Becomes non-toxic at high temperatures (above 90 degrees).

Where is it located and for what purposes is it used?

Where does castor grow? Its main habitats are China, India, and Bangladesh. However, in Russia you can also often find this plant, because castor oil is a fairly popular medicinal product.

Where is this poison used? Where can I find this substance?

Ricin has not found its use for medical purposes. Although many scientists have tried to use it to produce drugs for oncology.

In most cases, the toxic properties of ricin are used specifically for criminal purposes. Powder or aerosol with such a substance is fatal to humans.

On the Internet you can sometimes come across a question about how to obtain this poison at home. This is possible, but it is always worth remembering that such actions may be considered a criminal offense. Many terrorists have developed their own recipe for making such poison.

Effect of ricin on humans

What happens to the body during ricin poisoning?

It is worth noting that accidental intoxications are quite rare. Most poisonings are planned. There are several options for this.

Options:

• Ingestion with food or drinks,
• Inhalation of airborne powder
• Use of solution for injection.

Ricin does not have a negative effect on the skin. It is not absorbed through them in its pure form. Poisoning in this way is possible when mixing the poison with any solvents.

When ingested, ricin disrupts protein synthesis. It has a destructive effect on red blood cells, which either die or stick together as a result. As a result, cell destruction occurs and the functioning of organs and systems is disrupted.

The result can be death after quite a long period of suffering. The lethal dosage for an adult is twenty seeds; six is ​​enough for children.

Symptoms and signs of poisoning

What should you pay attention to in order to detect ricin poisoning in time?

Symptoms do not begin to appear immediately, but after a certain time (about 15 hours) when the toxin enters the mouth.

If poisoning occurs through the respiratory tract, the first signs can be noticed within four hours.

List of signs:

• nausea, vomiting,
• burning sensation on the mucous membranes,
• diarrhea, sometimes mixed with blood,
• pain in the stomach and intestines,
• bleeding in the eyes,
• convulsive state
• decrease in pressure,
• the skin becomes bluish,
• coughing,
• respiratory dysfunction,
• enlarged lymph nodes in the abdominal cavity,
• muscle paralysis.

In the absence of help, death occurs in about a couple of days. The man dies in severe pain. Unfortunately, there is no antidote for ricin.

First aid and treatment of intoxication

In case of ricin poisoning, it is very important to provide first aid to the person in a timely manner. The further outcome and life of the victim depends on this.

Therapy:

• Doctors must be called
• The victim should rinse the stomach with plenty of water with the addition of activated carbon,
• Then the poisoned person should be given a decoction of rice or jelly to drink,
• A person needs to be given a small amount of soda to alleviate the “suffering” of the kidneys.

Therapy is carried out in a hospital. There is no antidote for ricin. The medical institution takes all necessary measures to provide the necessary assistance.

Measures:

• If necessary, additional gastric lavage is performed,
• Various means are used to restore the functioning of systems and organs,
• Laxatives are used
• Blood transfusion is performed
• Various painkillers are prescribed.

Particular attention is paid to the kidneys due to the fact that ricin is excreted rather poorly by them, and they are subject to heavy load.

In the future, vitamin therapy is used, treatment is carried out until the entire body is completely restored.

What could be the consequences?

Ricin poisoning can cause quite serious consequences. With such intoxication, all body systems suffer.

What could be:

• The functioning of the digestive system is disrupted, the intestines suffer.
• The liver and pancreas also suffer quite severely. In the future, it is possible to develop toxic hepatitis and disrupt insulin production.
• The functioning of the urinary system may also be disrupted, and chronic diseases may worsen.

Ricin poisoning poses a great danger to humans. You should not plant this plant if there are small children in the house. After all, babies are very curious and put everything in their mouth. As a result, severe ricin toxicity may occur.

If signs of poisoning are detected, first aid must be provided to the person as quickly as possible, his life depends on it. And then transfer the victim to doctors for further treatment.

Ricin in the hands of terrorists and doctors

Food for thought

In early January 2003, British police arrested a group of terrorists, some of whom were trained in Chechnya. They didn't make bombs or hijack planes, but had their criminal activities been successful, the consequences could have been no less catastrophic.
In an underground laboratory, the criminals set up the production of ricin, a powerful poison, and meanwhile one of the detainees worked at a military base and had access to preparing food for soldiers. Adding a dose of poison into the cauldron that could kill hundreds of people at the same time would not be too difficult - the lethal dose of ricin is 80 times less than that of potassium cyanide, and is about 1 mg for a person. In 1978, Bulgarian dissident Georgi Markov was killed in London using this poison. He died from an injection with an umbrella, in the needle-tip of which a capsule with ricin was hidden.

Origin and effect of the poison

Where did this deadly substance come from and who invented it? It turns out that nature itself. The poison is contained in the seeds of a widespread plant that has been used in traditional medicine for centuries - castor bean (Ricinus communis).

Fig 1. Castor bean (Ricinus communis)

“But how can that be? - the knowledgeable reader will be surprised. - After all, castor oil is obtained from castor beans. More recently, it was used not only for the production of motor oils and strengthening hair, but also taken orally as a good laxative!” Indeed, ricinoleic acid triglyceride, known as castor oil, can be bought at the pharmacy without any prescription - this substance is completely harmless. Even if you swallow castor bean seeds whole without chewing, there will be no harm: they will pass through the entire digestive tract without being destroyed by enzymes.
But if the surface of castor bean seeds is damaged, the one who swallowed them - be it a person or a pet - will die. The fact is that after extracting the oil from castor bean seeds, all the poison remains in the cake. It is this that serves as the raw material for the production of ricin. Each fruit contains three spotted seeds from 5 to 15 mm long (Fig. 2).

Fig 2. Castor bean seeds - a source of ricin

Ricin poisoning can occur not only through food. If you inhale a powder or aerosol containing poison, the consequences can be equally dire. Meanwhile, the first signs of poisoning are sometimes mistaken for symptoms of an infectious disease. They do not appear immediately, but only a few hours after the poison enters the body. If it ends up in food, a person experiences weakness, abdominal pain, accompanied by vomiting and diarrhea with blood. Then the body becomes dehydrated and blood pressure drops. When ricin enters the lungs, the symptoms of poisoning resemble severe bronchitis or pneumonia. And the saddest thing is that there is no antidote for ricin yet. If a person is poisoned, he dies within 1-5 days, since the poison irreversibly damages the lungs, liver and kidneys.
Both in America and in Western European countries, frightened by terrorist attacks, doctors are specially introduced to the symptoms of ricin poisoning and tell the population about them, since in the hands of criminals this substance can be extremely dangerous. Ricin poisoning almost never happens in everyday life. The poison, fortunately, is very unstable and quickly decomposes under the influence of ultraviolet radiation, that is, simply put, under the rays of the sun.

Mechanism of action

But what kind of poison is this? How does it work and why is it so dangerous?
Ricin is a glycoprotein, that is, a protein whose amino acid chains form complexes with carbohydrate structures. This protein is a dimer, that is, it includes two protein chains - A and B. Chain A consists of 267 amino acid residues, with some of its fragments folded into spherical structures, and others into spirally twisted ribbons; one of the tapes contains
adenine ring (Fig. 3.). Proteins that closely resemble the A chain are not that rare. Wheat, barley and some other grains have them, which are not at all poisonous.

Figure 3. Three-dimensional representation of ricin chains modeled from X-ray diffraction data. In the upper part of the figure, the dotted line indicates circuit A, and in the lower solid line, circuit B.

In castor beans, such a protein turns into poison because it is cross-linked by a disulfide bridge with another protein chain - the B chain. This chain, consisting of 262 amino acid residues, is formed like a dumbbell. Monomer B is a lectin, a protein that can bind carbohydrates. At both ends of the dumbbell, it contains areas cross-linked with the sugar galactose, which, in turn, can form hydrogen bonds with other sugars galactose and N-acetylgalactosamine located on the surface of the cell membrane.
Due to this feature, lectins have a high affinity for receptors located on cell membranes and are able to deliver substances to which they are connected; Ricin enters the cell through normal endocytosis. In this case, monomer B facilitates the penetration of protein A into the cell. Once inside, it becomes very dangerous - it attaches to the ribosome (a kind of molecular machine for protein synthesis) and disrupts its functioning. A single ricin molecule in the cytoplasm can inactivate more than 1500 ribosomes per minute due to depurination of RNA in the protein-synthesizing apparatus. As a result, protein synthesis in the cell stops and it dies.

Ricin - for peaceful purposes

The mechanism of action of the poison has been studied quite well, and this opens up opportunities for using the substance for peaceful purposes. Medical science has more than once succeeded in taming and even taming poisons - there are many examples of this.
So they are trying to use ricin for medical purposes, making it kill not all cells, but only cancer cells or, say, some cells of the immune system when they interfere with transplantation.
To create an immunotoxin, the ricin monomer (chain A) is attached to antibodies - now they will perform the function of the lectin part. This product is highly specific and destroys only cells to which antibodies have affinity. When bone marrow is transplanted into a patient, ricin-based immunotoxins successfully destroy T-lymphocytes present in the donor's bone marrow. This reduces the possibility of rejection of the tissue transplanted to the recipient. Bone marrow transplant operations thus become more successful.
A similar approach is used in the treatment of leukemia and lymphoma. To do this, the patient's bone marrow is taken and treated with a ricin-based immunotoxin to destroy cancer cells. This bone marrow is then implanted back into the patient. Targeted delivery of small amounts of toxins to cancer cells gives better results than chemotherapy, in which large doses of poisons lead to the death of not only diseased but also healthy cells.
But that's not all. The scope of ricin is constantly expanding. Thus, scientists used its ability to interact with cell membranes in order to better understand the peculiarities of the nervous system. It turned out that by injecting ricin into the membrane of the nerve bundle, neurons can be selectively destroyed. At the same time, the peripheral nerves responsible for sensory and motor functions turned out to be especially sensitive to the poison. Neurons of the central nervous system are more resistant to it, which can be explained by the absence of sugars on the surface of their membranes, to which the ricin molecule has an affinity. Well, since there is no receptor, it means that the poison cannot penetrate the cell and paralyze the work of ribosomes. Thanks to the research, it became possible to model various types of neuronal damage and find ways to eliminate them, as well as draw up an anatomical map of neurons, noting on it the characteristics of the receptors of many of them.
In general, the conclusion from all that has been said is obvious: the substance itself, be it gunpowder, medicine or poison, is not good or bad, it all depends on whose hands it falls into.

Those who like to hunt with bladed throwing weapons: hunting crossbows and bows need to know some nuances, without which this type of hunting can, in some cases, become ineffective. St. John's worts who use throwing bladed weapons are well aware of all the pros and cons of hunting with or. A silent shot and an unafraid animal are a clear advantage of crossbow hunting. But, naturally, the power of destruction and the range to the target make the crossbow, compared to firearms, an outright disadvantage. But that's not all. An arrow can only kill small game, such as a hare or black grouse. You cannot kill a wild boar or an elk (there is no talk of a bear at all) with an arrow. Unless, of course, you hit such vital organs that the animal will “quickly” bleed out and throw off its hooves in a couple of days. A large animal, having received an arrow in the side, will make its legs and, if the hunter does not continue to pursue it, waiting a week for the “meat” to die and, if possible, firing another bolt at it, then the animal may well recover from the wound. And even the most stubborn tracker can be left with his nose, chasing a wounded animal for a long time, and, in the end, giving up on this idea, he will go hunting for hares. But there is a way out. True, this solution applies more to hunters who slaughter an animal for its skin, and not for eating.

What plant can poison be prepared from?

Since ancient times, hunters have used various poisons to hunt large animals. Today we will talk about preparing one of these poisons. A poisonous decoction that can kill an animal within a few minutes, even if its injury is minor, can be made from hellebore root. This highly poisonous plant has several varieties and grows almost all over the world.

Here we describe a method for preparing a poisonous decoction of white hellebore, which usually grows in wet meadows, near springs, livestock pastures, grass swamps, in light forests, and is most often found in the mid-mountain and alpine zones of the mountains in Western and Central Europe.

In Russia you can more often find black hellebore (it grows in the European part of Russia, Siberia, and the Far East)

and hellebore (grows in the wet meadows of the Far East and Siberia).

I think the technology for preparing poison from “Russian hellebore” will not differ from the hellebore of the Alpine mountains described below.

The plant is usually harvested in the month of August, when it is most toxic. To prepare a poisonous decoction, small roots that are dark in color or yellowed are selected.

Technology for preparing poison from hellebore

The poison is prepared as follows. Hellebore roots are cleaned from the soil and washed well. Then they need to be placed under some kind of press to squeeze out the juice. This juice is collected in a metal container and boiled. When boiling hellebore juice, foam and gluten appear on the surface, which must be removed with a spoon. After this, the liquid must be filtered and left to infuse in the sun (from sunrise to sunset). This process must be repeated for three to four days. Each time, hellebore juice must be filtered. This is done until it becomes thick and resembles sugar syrup in color. If, after sniffing this syrup, you start to sneeze, then the poison is ready.

When preparing poison from hellebore, you can simply evaporate its juice rather than leaving it in the sun, but in this case, the decoction will be less toxic. You can test the effect of the poison on chickens. This is done as follows. Take a thread and a needle. The thread is moistened with the prepared poison. Then we pass it between the skin and muscle tissue of the chicken's foot until blood comes out. After a minute, the chicken should “fall asleep.”

How does hellebore poison affect animals?

It looks like this. When we wound a large animal, such as a lynx or a wolf, with an arrow dipped in hellebore poison, it runs no more than a hundred meters. Then he stops and stands motionless for several seconds. The poison reaches the animal's heart through the bloodstream, and it falls dead (provided that the poison is prepared correctly and has a strong concentration of toxic substances). Also signs of the poison's effect are coughing, vomiting and jerking of the animal's head.

There are, of course, other poisonous decoctions from other herbs, but we may talk about them later. Some of them are slower, others faster. In every region of our country, there are herbs that can be used to prepare poisons. I think that a real hunter should know about the methods of preparing plant poisons. Such knowledge will obviously not be superfluous. But I repeat once again, an animal poisoned by hellebore plant poison is not suitable for consumption. In this way, you can hunt a fur-bearing animal, or any other animal that you intend to place in your home as a stuffed animal. Good luck!

Omega is a highly toxic substance that is part of hemlock. Just 100 milligrams of it (8 leaves) will be enough to kill a person. How it works: all body systems gradually fail, except the brain. As a result, you, being in your right mind, begin to die slowly and painfully until you suffocate.

The most popular hemlock was among the Greeks. Interesting fact: this plant caused the death of Socrates in 399 BC. The Greeks executed him in this way for disrespect for the gods.

No. 9 - Aconite

This poison is obtained from the fighter plant. It causes arrhythmia, which ends in suffocation. They say that even touching this plant without gloves can result in death. It is almost impossible to detect traces of poison in the body. The most famous case of use is that Emperor Claudius poisoned his wife Agrippina by adding aconite to her mushroom dish.

#8 - Belladonna

In the Middle Ages, belladonna was used as a women's cosmetic (rouge for cheeks). Special drops were even obtained from the plant to dilate the pupils (at that time this was considered fashionable). You could also swallow belladonna leaves - one is just enough for a person to die. Berries are also not a miss: you only need to eat 10 of them to die. In those days, a special poisonous solution was made from the latter, which was used to lubricate arrowheads.

#7 - Dimethylmercury

This is the slowest and most insidious killer. This is because even 0.1 milliliter that accidentally gets on your skin will be enough to be fatal. The most notorious case: in 1996, a chemistry teacher at Dartmouth College in New Hampshire dropped a drop of poison onto her hand. Dimethylmercury burned through a latex glove; symptoms of poisoning appeared after 4 months. And 10 months later the scientist died.

#6 - Tetrodotoxin

This poison is found in blue-ringed octopuses and pufferfish. With the former, things are very bad: octopuses deliberately attack their prey with tetrodotoxin, imperceptibly pricking it with special needles. Death occurs within a few minutes, but symptoms do not appear immediately - after paralysis sets in. The venom of one blue-ringed octopus is enough to kill 26 healthy men.

It’s easier with fugu: their poison is only dangerous when you’re about to eat the fish. It all depends on the correct preparation: if the cook is not mistaken, the tetrodoxin will all evaporate. And you will eat the dish without any consequences, except for incredible adrenaline rushes...

#5 - Polonium

Polonium is a radioactive poison for which there is no antidote. The substance is so dangerous that just 1 gram of it can kill 1.5 million people in a few months. The most sensational case of the use of polonium was the death of Alexander Litvinenko, an employee of the KGB-FSB. He died in 3 weeks, the reason was that 200 grams of poison were found in his body.

#4 - Mercury

1. elemental mercury - found in thermometers. Instant death occurs if it is inhaled;
2. inorganic mercury - used in the manufacture of batteries. Lethal if swallowed;
3. organic mercury. Sources are tuna and swordfish. It is recommended to eat no more than 170 grams per month. Otherwise, organic mercury will begin to accumulate in the body.

The most famous case of use is the poisoning of Amadeus Mozart. He was given mercury tablets to treat syphilis.

Recipes for such dangerous drugs can be found in chemistry books, on the Internet, or you can come up with them yourself. The main thing is not to forget about precautions.

Preparation of poisons from plants

Before you find out the recipe and make the original poison, you should familiarize yourself with the dangerous composition of some plants.

1. Aconite– all parts of the plant contain alkaloids, most notably aconitine, which is dangerous to humans.
2. Podbel– its leaves and flowers contain a deadly poison – rhodotoxin, which, when entering the body, first leads to overexcitation of the nervous system, and then to its depression, which leads to death.
3. Kutra– the glycoside cymarin, contained in all parts of the plant, causes severe arrhythmia and cardiac arrest in people who do not have health problems.
4. Asarum– contains three substances that can poison a person or animal. Glycosides, the alkaloid azorine and asarone, are “strong killers” of plant origin.

Just 20-25 g of raw materials from each plant separately is enough to prepare poison at home. To do this, you need to pour the required amount, or rather 500 ml of boiling water, leave for several hours and that’s it, the poison is ready.

The most popular household poison at home can be prepared from castor beans. This plant can be found in the wild, but today more and more housewives use it to decorate flower gardens.

During military operations, ricin contained in castor beans was used to kill terrorists. To do this, the dried fruits of the bush were ground into powder and added to water.

Today, the fruits, which are very similar in appearance to the Colorado potato beetle, often fall into the hands of children and the consequences of such interaction are disastrous for parents. To protect yourself, and especially your children, from the deadly influence of castor beans, it is better not to plant them near the house or in the garden.

Poisonous properties of mushrooms

About 37% of the world's inhabitants do not eat mushrooms for fear of getting poisoned.

The most popular types of mushrooms that can poison a person are toadstool and fly agaric. Toadstool contains amatoxin, which is not destroyed by heat treatment.

Amanitas are also rich in deadly poison, but its name is muscarine. Both components are not destroyed during heat treatment.

Whole raw materials need to be crushed, pour boiling water over them, and boil for 30-40 minutes. The resulting decoction should be added to aromatic food for rodents (for example, cheese, mixed nuts). It is important to protect yourself before preparing the decoction - put on a respirator and gloves before starting the procedure.

What medications can turn into poison?

To make a homemade poisonous product, use recipes based on medications. The most popular drug is isoniazid, used to treat tuberculosis. It is sold in liquid and powder form in ampoules. It can be obtained at any pharmacy.

Few people know that it is not only the product that is popularly called poisonous that is fatal to a living organism. At first glance, seemingly harmless medications used daily in large doses can poison.

These include: the sleeping pill and sedative Barboval, the tranquilizer Seduxen and even paracetamol, which is present in every home.

To avoid becoming a victim of fatal poisoning, you should not take high doses of these drugs.

Potassium cyanide- another substance from which medicines against rheumatism were made back in the 19th century. Today it is used to create electroplating and can be purchased, but not in a pharmacy, but in special stores.

But there are people who use it to get rid of animals - dogs, cats, rodents. It is important to remember that the person who created such a substance, and as a result it caused the death of a person, will face criminal liability.

It is better for people who do not understand poisons at all not to start experiments. According to statistics, in 50% of cases, poisonous products prepared at home carried a mortal danger to humans or pets.

1. Botulinum toxin

Many poisons can be lethal in small doses, so it is quite difficult to single out the most dangerous one. However, many experts agree that botulinum toxin, which is used in Botox injections to smooth out wrinkles is the strongest.

Botulism is a serious disease leading to paralysis, caused by botulinum toxin, which is produced by bacteria Clostridium botulinum. This poison causes damage to the nervous system, respiratory arrest and death in terrible agony.

Symptoms may include nausea, vomiting, double vision, facial weakness, speech impediments, difficulty swallowing and others. The bacterium can enter the body through food (usually poorly canned foods) and through open wounds.

2. Poison ricin

Ricin is natural poison obtained from castor beans castor bean plants. A few grains are enough to kill an adult. Ricin kills cells in the human body, preventing it from producing the proteins it needs, resulting in organ failure. A person can become poisoned by ricin through inhalation or ingestion.

If inhaled, symptoms of poisoning usually appear within 8 hours of exposure and include difficulty breathing, fever, cough, nausea, sweating and chest tightness.

If ingested, symptoms appear in less than 6 hours and include nausea and diarrhea (possibly bloody), low blood pressure, hallucinations and seizures. Death may occur within 36-72 hours.

3. Sarin gas

Sarin is one of the the most dangerous and deadly nerve gases, which is hundreds of times more toxic than cyanide. Sarin was originally produced as a pesticide, but the clear, odorless gas soon became a powerful chemical weapon.

A person can be poisoned by sarin gas by inhaling or exposing the gas to the eyes and skin. Initially, symptoms may appear such as runny nose and chest tightness, difficulty breathing and nausea.

Then the person loses control over all functions of his body and falls into a coma, convulsions and spasms occur until suffocation occurs.

4. Tetrodotoxin

This deadly poison found in the organs of fish of the genus pufferfish, from which the famous Japanese delicacy “fugu” is prepared. Tetrodotoxin persists in the skin, liver, intestines and other organs, even after the fish has been cooked.

This toxin causes paralysis, convulsions, mental disorder and other symptoms. Death occurs within 6 hours after ingestion of the poison.

Every year, several people are known to die painful deaths from tetrodotoxin poisoning after eating fugu.

5. Potassium cyanide

Potassium cyanide is one of the fastest deadly poisons known to mankind. It may be in the form of crystals and colorless gas with the smell of “bitter almonds”. Cyanide can be found in some foods and plants. It is found in cigarettes and is used to make plastic, photographs, extract gold from ore, and kill unwanted insects.

Cyanide has been used since ancient times, and in the modern world it has been a method of capital punishment. Poisoning can occur through inhalation, ingestion and even touching, causing symptoms such as seizures, respiratory failure and in severe cases death, which may occur in a few minutes. It kills by binding to iron in blood cells, making them unable to carry oxygen.

6. Mercury and mercury poisoning

There are three forms of mercury that can be potentially hazardous: elemental, inorganic and organic. Elemental mercury, which found in mercury thermometers, old fillings and fluorescent lamps, non-toxic on contact, but may be fatal if inhaled.

Inhalation of mercury vapor (the metal quickly turns into a gas at room temperature) affects the lungs and brain, turning off the central nervous system.

Inorganic mercury, which is used to make batteries, can be fatal if ingested and cause kidney damage and other symptoms. Organic mercury found in fish and seafood is usually hazardous over long-term exposure. Symptoms of poisoning may include memory loss, blindness, seizures and others.

7. Strychnine and strychnine poisoning

Strychnine is an odorless, white, bitter crystalline powder that can be acquired by ingestion, inhalation, solution, and intravenous injection.

They get it from the seeds of the chilibuha tree(Strychnos nux-vomica), native to India and southeast Asia. Although it is often used as a pesticide, it can also be found in drugs such as heroin and cocaine.

The degree of strychnine poisoning depends on the amount and route of entry into the body, but a small amount of this poison is enough to cause a serious condition. Symptoms of poisoning include muscle spasms, respiratory failure and even lead to brain death 30 minutes after exposure.

8. Arsenic and arsenic poisoning

Arsenic, which is the 33rd element in the periodic table, has been synonymous with poison since ancient times. It was often used as a poison of choice in political assassinations, as Arsenic poisoning resembled cholera symptoms.

Arsenic is considered a heavy metal with properties similar to those of lead and mercury. In high concentrations it can lead to symptoms of poisoning such as abdominal pain, cramps, coma and death. In small amounts, it can contribute to a number of diseases, including cancer, heart disease and diabetes.

9. Poison curare

Curare is a mixture of various South American plants that were used for poison arrows. Curare has been used for medicinal purposes in a highly diluted form. The main poison is an alkaloid, which causes paralysis and death, as well as strychnine and hemlock. However, after respiratory paralysis occurs, the heart may continue to beat.

Death from curare is slow and painful, as the victim remains conscious but cannot move or speak. However, if artificial respiration is applied before the poison settles, the person can be saved. Amazon tribes used curare to hunt animals, but the poisoned animal meat was not dangerous to those who consumed it.

10. Batrachotoxin

Fortunately, the chances of encountering this poison are very small. Batrachotoxin, found in the skin of tiny dart frogs, is one of the most powerful neutrotoxins in the world.

Frogs themselves do not produce poison; it is accumulated from the foods they consume, mainly small bugs. The most dangerous poison content was found in a species of frogs terrible leaf climber, living in Colombia.

One specimen contains enough batrachotoxin to kill two dozen people or several elephants. I affects nerves, especially around the heart, makes breathing difficult and quickly leads to death.

Many doctors know how to poison a person at home and how to avoid suspicious signs, however, such an act is criminally punishable. Nevertheless, today some people resort to this method in order to eliminate a rival, often this happens in criminal communities.

Natural products are dangerous if you know what can poison a person. Death is influenced not only by pathogens, but also by compounds. A well-known poison is botulinum toxin, which is produced by special microbes that can multiply intensively in a protein environment. It is the cause of intoxication after eating spoiled canned food, mushrooms and other foods. In the digestive tract, this toxin is not destroyed by enzymes and is absorbed into the mucous membranes of the stomach and intestines.

Persons who choose what to poison a person to death rarely choose botulinum toxin, since death in this case is rare.

However, signs of illness can always be attributed to the last meal, during which canned goods, sausage and other unsafe foods were consumed. Symptoms of poisoning are nausea, vomiting and dry skin, followed by paralysis of the striated muscles.

Most people are familiar with castor oil, but few are aware of ricin, a toxin found in castor bean seeds. Criminals looking for something to quietly poison a person often settle on this poison. It is odorless white crystals that dissolve in liquid, however, when the aqueous solution is boiled, the dangerous properties of ricin disappear.

The toxic substance does not penetrate the skin; it acts only when it enters the body. In case of ricin poisoning, the latent period of intoxication varies from 15 to 24 hours, sometimes symptoms appear earlier. Thus, intestinal colic, bloody diarrhea, nausea and vomiting are detected, and hemorrhages occur on the retina.

If a significant portion of castor bean seeds enters the body, death occurs after 6 days due to damage to internal organs, as well as extensive bleeding.

This poison is sometimes chosen by attackers who think about how they can quickly poison a person. However, death is rare.

The poison of the toadstool was known to medieval politicians and healers, who knew how to poison a person to death. Today, scientists have found that the mushroom contains toxins such as phalloidins and alpha-amanitins, which act quickly and irreversibly; these substances are not destroyed by heat treatment.

The latent period without alarming signs lasts up to 40 hours before the poison enters the blood in large quantities and causes depressing signs of poisoning. It is characterized by diarrhea, vomiting and dehydration, as well as pale skin and increased heart rate. After a few days, extensive damage to the internal organs - the liver and kidneys - occurs, toxic hepatitis develops, after which death is declared.

How can you poison a person, if you do not take into account the above-mentioned means? The following components are used for this purpose:

• atropine;
• solanine;
• aflatoxin.

Atropine is a substance from the group of alkaloids, found in plants - belladonna, datura, henbane and others. Intoxication occurs 1 hour after taking the poison; the degree of poisoning may vary.

Atropine is known to affect the structure of the brain, causing loss of coordination and damage to the heart and lungs. Death occurs infrequently due to an insufficient dose of toxin.

How to briefly poison a person? In this case, the solanine found in root vegetables is a suitable option. It can be found not only in potatoes, but also in tomatoes and eggplants.

Intoxication manifests itself in the form of nausea, vomiting, cramping pain in the abdomen and a feeling of bitterness in the mouth. However, it is unlikely to consume a large dose of solanine, which is why the victims are not in danger of death.

In addition, aflatoxins are a common method of poisoning - a group of toxic substances secreted by a microscopic fungus. If stored improperly, it affects various food products, for example, dried fruits, milk, rice, tea and much more.

The poison in large quantities causes the death of liver cells, however, the poisoning passes without serious consequences and is limited to a temporary deterioration in health

In the old days, people knew the best way to poison a person. This can be easily done with the help of ordinary mercury; the dangerous metal causes fatigue, headaches, and memory loss. In addition, there is an increase in body temperature and a decrease in blood pressure. The digestive system also suffers, and diarrhea and a metallic taste in the mouth are often observed. When a significant amount of mercury vapor is inhaled, death is inevitable, which is why this drug has been a weapon for centuries for criminals who understood how to poison a person without any trace of a crime.
