The most dangerous poison in the world for humans. For everyone and about everything

Foods and drinks that are very familiar to us can turn out to be deadly. And the simplest objects contain poison. It turns out that the most powerful poisons are sometimes close to us, and we don’t even suspect it.
We present to your attention a list of the most known poisons which have been used to kill people throughout history.

1. Hemlock

Hemlock is a genus of highly toxic flowering plants, common in Europe and South Africa. The ancient Greeks used it to kill their captives. For an adult, 100 mg is enough. infusion or about 8 hemlock leaves to cause death - your mind is awake, but your body does not respond and eventually the respiratory system stops. The most famous case of poisoning is considered to be one sentenced to death for atheism in 399 BC. e., the Greek philosopher Socrates, who received a very concentrated infusion of hemlock.

2. Fighter or Wolfsbane

Ninth place in the list of the most famous poisons is taken by Borets - a genus of perennial poisonous plants, growing in damp places along the banks of rivers in Europe, Asia and North America. The poison of this plant causes asphyxia, which leads to suffocation. Poisoning can occur even after touching the leaves without gloves, since the poison is absorbed very quickly and easily. According to legend, Emperor Claudius was poisoned by the poison of this plant. It was also used to lubricate bolts for the Chu Ko Nu crossbow, one of the unusual ancient types of weapons.

3. Belladonna or Belladonna

The name belladonna comes from the Italian word and translates as “ beautiful woman" In the old days, this plant was used for cosmetic purposes - Italian women dropped belladonna juice into their eyes, the pupils dilated, and the eyes acquired a special shine. The berries were also rubbed on the cheeks to give them a “natural” blush. It is one of the most poisonous plants in the world. All its parts are toxic and contain atropine, which can cause severe poisoning.

4. Dimethylmercury

Dimethylmercury is a colorless liquid and one of the most powerful neurotoxins. Hit 0.1 ml. this liquid on the skin is already fatal for humans. It is interesting that symptoms of poisoning begin to appear after several months have passed, which is already too late for effective treatment. In 1996, inorganic chemist Karen Wetterhahn was conducting experiments at Dartmouth College in New Hampshire and spilled one drop of this liquid on her gloved hand - dimethylmercury was absorbed into the skin through the latex gloves. Symptoms appeared four months later, and Karen died ten months later.

5. Tetrodotoxin

Tetrodotoxin is found in two sea ​​creatures- blue-ringed octopus and fugu fish. The octopus is the most dangerous because it deliberately injects its venom, killing its prey within minutes. It has enough poison to kill 26 adults within minutes. The bites are often painless, so many people only realize they have been bitten when paralysis occurs. But fugu fish is only lethal when eaten. But if the fish is cooked correctly, it is harmless.

6. Polonium

Polonium is a radioactive poison and a slow killer. One gram of polonium vapor can kill about 1.5 million people in just a couple of months. Most famous case poisoning presumably with polonium-210, there was a case of poisoning of Alexander Litvinenko. Polonium was found in his cup of tea - a dose 200 times the average lethal dose. He died three weeks later.

7. Mercury

Mercury is a relatively rare element that, when room temperature is a heavy silvery-white liquid. Only vapors and soluble mercury compounds are poisonous, causing severe poisoning. Metallic mercury does not have a noticeable effect on the body. A famous case of death from mercury (allegedly) is the Austrian composer Amadeus Mozart.

8. Cyanide

Cyanide is a deadly poison that results in internal asphyxia. The lethal dose of cyanide for humans is 1.5 mg. per kilogram of body weight. Cyanide was usually sewn into the collars of the shirts of scouts and spies. In addition, the poison was used in gaseous form in Nazi Germany for mass murder in gas chambers during the Holocaust. It is a proven fact that Rasputin was poisoned with several lethal doses of cyanide, but he never died, but was drowned.

9. Botulinum toxin

Botulinum toxin is the most powerful poison from known to science organic toxins and substances in general. The poison causes severe toxic damage - botulism. Death occurs from hypoxia caused by impaired oxygen metabolism, asphyxia of the respiratory tract, paralysis of the respiratory muscles and cardiac muscle. And now scientists will not answer the question of what poison is the most powerful in the world. Some of the most strong poisons are toxins from botulism and tetanus. The source of botulism infection is homemade preparations.

Botulinum toxin is produced by the bacteria Clostridium botulinum, which are the causative agents of the most dangerous disease - botulism. This is the most powerful poison of organic nature and one of the strongest poisons in the world. In the last century, botulinum toxin was included in the arsenals chemical weapons, but at the same time active research was conducted regarding its use in medicine. And today a huge number of people who want to at least temporarily restore the smoothness of their skin are influenced by this the most terrible poison, which is part of the most popular medicinal product"Botox", which once again confirms the truth famous saying the great Paracelsus: “Everything is poison, everything is medicine; both are determined by the dose.”

10. Arsenic

Arsenic was recognized as the “king of poisons.” Arsenic poisoning causes symptoms similar to those of cholera (abdominal pain, vomiting, diarrhea). Arsenic, like Belladonna (item 8), was used in ancient times by women to make their faces pale white. There is an assumption that Napoleon was poisoned on the island of St. Helena with arsenic compounds.

11. Methanol, or methyl alcohol

It is a very dangerous poison. This is explained by the fact that it is easy to confuse it with ordinary wine alcohol, since they are indistinguishable in taste and smell. Fake alcoholic drinks sometimes made on the basis methyl alcohol, but without an examination it is impossible to determine the presence of methanol. Unfortunately, the consequences of consuming such drinks are irreversible; at best, a person becomes blind.

12. Snake venom

There are more than two and a half thousand species of reptiles, but only about 250 species are poisonous. The most famous - common vipers, cobras, rattlesnakes, black mambas, small snakes - sand frets. Poisonous snakes- unpleasant neighbors. People have long found out that snake venom is dangerous only when it enters the human bloodstream. And, since humanity has been dealing with snakes for many millennia, it is not surprising that it was while studying the effects of snake venom on the bodies of animals and people that the first antidote was created in 1895 - anti-snake serum. By the way, there is no universal antidote even in case of poisoning snake venom, for each species of snakes its own antitoxin is created - for king cobra- one, for vipers - another, for rattlesnakes - a third.

13. Vi-Ex (VX)

VX, or, as it is also called, VI gas, belongs to the category of chemical warfare gases that have a nerve-paralytic effect. It was also born as a new pesticide, but soon the military began to use it for their own purposes. Symptoms of poisoning with this gas appear within 1 minute after inhalation or contact with the skin, and death occurs within 10-15 minutes.

14. Bacillus anthrax

Anthrax is a very serious, rapidly developing disease caused by the bacteria Bacillus anthracis. There are several forms anthrax. The most “harmless” one is the skin one. Even without treatment, the mortality rate from this form does not exceed 20%. The intestinal form kills about half of those sick, but the pulmonary form is almost certain death. Even with the help the latest techniques modern doctors manage to save no more than 5% of patients.

15. Sarin

Sarin was created by German scientists trying to synthesize a powerful pesticide. But this dark glory deadly poison, which causes quick but very painful death, was acquired not in agricultural fields, but as a chemical weapon. Sarin was produced by the ton for military purposes for decades, and it was only in 1993 that its production was banned. But despite calls for the complete destruction of all stocks of this substance, both terrorists and the military still use it in our time.

16. Amatoxins

Amatoxins are a whole group of protein poisons contained in poisonous mushrooms of the amanita family, including the deadly toadstool. The particular danger of these poisons lies in their “slowness”. Once they enter the human body, they immediately begin their destructive activity, but the victim begins to feel the first discomfort no earlier than 10 hours later, and sometimes several days later, when it is already very difficult for doctors to do anything. Even if such a patient can be saved, he will still suffer for the rest of his life from painful dysfunctions of the liver, kidneys and lungs.

In summer and autumn, the time comes for seasonal mushroom poisoning - by the way, these are the most accessible poisonous substances today. The most famous poisonous mushrooms are false honey mushrooms, pale toadstool, lines and fly agarics. The most commonly poisoned is the toadstool, since it has many varieties, sometimes indistinguishable from edible mushrooms, and one such mushroom can lead to the death of several people. False mushrooms are the most common poisonous mushrooms. Although the Germans have learned to prepare fly agarics in such a way that they are not poisoned by them, it is true that it takes them a lot of time to prepare these mushrooms - they boil them for days. True, the question arises - why do they need fly agaric mushrooms when you can just take other mushrooms for food? And of course, we must remember the rules for storing cooked mushrooms; even edible mushrooms can become poisonous if the shelf life is violated.

17. Strychnine

Strychnine in large quantities found in nuts tropical tree chilibuha. It was from them that it was obtained in 1818 by the French chemists Pelletier and Cavantou. In small doses, strychnine can be used as a medicine that increases metabolic processes, improves heart function and treats paralysis. It was even actively used as an antidote for barbiturate poisoning. However, it is one of the most powerful poisons. His lethal dose even less than the famous potassium cyanide, but it acts much more slowly. Death from strychnine poisoning occurs after about half an hour of terrible agony and severe convulsions.

18. Potatoes and grains

Regular potatoes or bread can also be poisonous. When stored improperly, potatoes accumulate the substance solanine, which causes poisoning to the body. And bread becomes poisonous if flour was used to make it and contained cereals contaminated with ergot. We are not talking about fatal poisoning, but it is quite possible to ruin your health with such products. An ear affected by ergot. In addition, there are many household chemicals and fertilizers, which can also cause poisoning. For example, potassium chloride is the most common fertilizer, but if it gets into the bloodstream it becomes deadly, since potassium ions block the activity of the heart.

19. Curare

The most famous poison B South America The most famous poison is curare, a poison plant origin, there are several subtypes of this poison. It causes paralysis of the respiratory system. Initially it was used for hunting animals, but in the 20th century it was successfully used in medicine. Curare is the most famous poison among the Indians.

20. Batrachotoxin

Among natural poisons, batrachotoxin is very dangerous; it is secreted by the skin of small but dangerous amphibians - dart frogs, fortunately, they can only be found in Colombia. One such frog contains so much toxic substance that it is enough to destroy several elephants. Poison frog there is no need to hide. In addition, there are radioactive poisons, such as polonium. It acts slowly, but only 1 gram of this substance is needed to destroy one and a half million people. Snake venom, curare, potassium cyanide - they are all inferior to the above poisons. It's not just snakes that are poisonous. The most poisonous creature on Earth is the jellyfish.

21. Ricin

Ricin is an extremely powerful poison of plant origin. The greatest danger is inhaling its smallest grains. Ricin is about 6 times more powerful poison than potassium cyanide, but as a weapon mass destruction it was not used due to purely technical difficulties. But various intelligence services and terrorists are very fond of this substance. Politicians and public figures with enviable regularity they receive letters stuffed with ricin. True, the case quite rarely ends in death, since the penetration of ricin through the lungs is quite low in efficiency. For a 100% result, ricin must be injected directly into the blood.

The most famous poisoners

The story of the Italian Borgia dynasty of poisoners, who elevated poisoning almost to the level of art, is unique. Everyone without exception was afraid of their invitation to the feast. The most famous representatives of this family for their treachery are Pope Alexander VI Borgia and his children: son Cesare, who became a cardinal, and daughter Lucrezia. This family had their own poison, "cantarella", supposedly containing arsenic, phosphorus and copper salts. It is known that the head of the family himself ultimately paid with his life for his treachery, having mistakenly drunk a cup of poison that he had prepared for another. Secret rings became the weapon of poisoners in the Middle Ages. In France, arsenic was used by women, the most famous of them was Catherine de Medici, who became Queen of France. There were also poisoners of lower rank - favorites of kings, marquises, baronesses and wives of jewelers. It is believed that Napoleon was poisoned with arsenic.

People often think of poisons as a myth from Shakespeare's dramas, or ripped from the pages of Agatha Christie's novels. But in fact, poison can be found everywhere: in cute little bottles under the kitchen sink, in our drinking water and even in our blood. Below are ten of the world's most under-the-radar poisons, some exotic, others frighteningly common.

10. Hydrogen Cyanide

Although cyanide carries a terrible stigma, its history is rich and fruitful. Some scientists even believe that cyanide may have been one of the chemicals that helped form life on earth. Today it is better known as the lethal substance, the active ingredient in Zyklon B, which the Nazis used to exterminate Jews in showers. Cyanide is chemical, used as capital punishment in the gas chambers of the United States. Those who have been in contact with the substance describe its odor as similar to that of sweet almonds. Cyanide kills by binding to the iron in our blood cells and destroying them, making them unable to carry oxygen throughout the body. Most states in the United States have stopped using the gas chamber, as this type of death penalty is considered unnecessarily cruel. Death can take several minutes and is often horrific to watch as the condemned convicts writhe in agony and salivate profusely as the body attempts to prevent death.

9. Hydrofluoric acid or hydrofluoric acid(Hydrofluoric Acid)


Hydrofluoric acid is used in a number of industries, such as metallurgy and even in the manufacture of Teflon. There are much more powerful acids in the world than hydrofluoric acid, but few of them are as dangerous to humans. In gaseous form it can easily burn out the eyes and lungs, but in liquid form it is especially insidious. Initially, when it comes into contact with human skin, it is completely imperceptible. Due to the fact that it does not cause pain upon contact, people can become seriously poisoned without noticing it. It penetrates the skin into the bloodstream, where it reacts with calcium in the body. In the worst cases, it seeps through the tissue and destroys the bone underneath.

8. Batrachotoxin


Fortunately for most of us, our chance of encountering batrachotoxin is incredibly small. Batrachotoxin is one of the most potent neurotoxins in the world and is found in the skin of tiny dart frogs. Frogs do not produce the poison themselves, it is produced in their bodies by the food they eat, most likely from eating tiny bugs. There are several different versions poison depending on the type of frog, the most dangerous is the type of batrachotoxin produced by the Colombian frog called the terrible leaf climber. This frog is so tiny that it can fit on the tip of your finger, but the poison on the skin of one frog is enough to kill about two dozen people, or a couple of elephants. The toxin attacks nerves, opening their sodium channels and causing paralysis, essentially shutting down the entire body's ability to communicate with itself. There is no antidote in the world, and death occurs very quickly.

7. VX Nerve Gas


Banned from use by the Chemical Weapons Convention (global supplies of this gas are gradually decreasing), VX nerve gas is considered the most powerful nerve gas in the world. The danger of this gas, discovered completely by accident in 1952 during chemical testing of organophosphates, was quickly discovered. Marketed as a pesticide under the name "Amiton", it was soon withdrawn due to its being too dangerous to society. It soon attracted the attention of world governments as it was a time of political unrest cold war, and gas began to be stockpiled for potential use in war. Luckily, no one started a war and the VX was never used in combat. A cultist from the Japanese group Aum Shinriyko stole some of this gas and used it to kill a man - this was the only famous death human caused by VX gas. The gas stops the production of enzymes in the nerves, causing the nerves to be in a constant state of activity, creating a “storm” in the nervous system that quickly overloads and destroys the body.

6. Agent Orange


Almost everyone has heard of the defoliant Agent Orange, created by Dow Chemical and Monsanto (which are considered the most evil corporations in the world). Agent Orange was used during the Vietnam War to eradicate trees that provided cover for enemy soldiers and to destroy crops in rural areas. Unfortunately, in addition to being a plant-killing agent, the herbicides contained a chemical dioxin called TCDD (tetrachlorodibenzo-p-dioxin), a known carcinogen that causes a significant increase in the risk of cancer, especially lymphoma, in those exposed to it. In addition, tens of thousands of Vietnamese children were born stillborn or with birth defects such as cleft palate, extra fingers and toes, and mental retardation. Vietnam remains very polluted to this day.

5. Ricin


Derived from the castor bean plant, ricin is one of the most deadly poisons. A small dose, comparable to a few grains of salt, is enough to kill an adult. The venom stops the production of proteins that the body needs to survive, causing victims to go into shock. Because of simple process produced by him, ricin has been weaponized by many governments around the world, and was used at least once for murder, when the Bulgarian dissident writer Georgi Markov was shot with ricin pellets on a London street in 1978. It is believed that the Bulgarian secret police and/or the KGB were responsible for the murder.

4. Arsenic


The metalloid arsenic has been used for centuries for a variety of purposes, from weapons production to cosmetics during the Victorian era (when sickly pallor was considered a fashion statement among women). During the Dark Ages, arsenic became a popular poison for assassins due to its effect - arsenic poisoning has symptoms similar to cholera, which was widespread during those times. Arsenic attacks adenosine triphosphatases in human cells, cutting off the flow of energy. Arsenic is a very unpleasant substance that, in strong concentrations, can cause different kinds gastrointestinal disorders with bleeding, convulsions, coma and death. In small amounts taken on a regular basis (for example, through arsenic-contaminated water), arsenic has been linked to a number of diseases, such as cancer, heart disease and diabetes.

3. Lead


Lead is one of the very first metals used by man. Its first smelting was made 8,000 years ago. However, its dangerous effects on the body became known only a few decades ago - lead affects every organ in the human body, so lead poisoning manifests itself through a range of symptoms, ranging from diarrhea to mental retardation. Children are especially at risk of poisoning; fetal exposure to lead causes pathological neurological disorders. The strangest thing is that many criminologists believe that the widespread decline in the number violent crimes is at least partly the result of increased restrictions on the use of lead. Children born after 1980 were much less likely to be exposed to lead and, as a result, were less likely to become violent.

2. Brodifacoum


Immediately after the end of World War II, the poison warfarin began to be used as a rodenticide (and interestingly enough, it was also used as an anticoagulant for people with bleeding disorders). But rats are known for their ability to survive at all costs, and over time, many of them have become resistant to warfarin. Therefore, it was replaced by brodifacoum. An extremely lethal anticoagulant, brodifacoum reduces the amount of vitamin K in the blood. Due to the fact that vitamin K is necessary for the blood clotting process, the body over time is subject to severe internal bleeding as blood spreads throughout the body from the rupture of tiny capillaries. Brodifacoum, which is sold under brands such as Havoc, Talon, and Jaguar, must be handled with great care because it penetrates the skin easily and remains in the body for many months.

1. Strychnine


Derived primarily from a tree called chilibuha, which is native to India and southeast Asia, strychnine is an alkaloid substance and is used as a pesticide, especially in rodent control. Death caused by strychnine poisoning is terribly painful. As a neurotoxin, strychnine attacks the spinal nerves, causing seizures and violent muscle contractions. Oskar Dirlewanger, a Nazi SS commander during World War II, injected his prisoners with strychnine and amused himself by watching them writhe. Strychnine is one of the few substances on this list that is both cheap and available on the market. It's possible that strychnine is sold at your local hardware store under a name like "Rodent Killer" or something similar.

A poison is a toxin that can cause severe poisoning or even death. The effect on a person depends on the amount of poison, as well as its type. It can enter the body through the mouth, respiratory organs and skin. Symptoms of poisoning may appear immediately after contact or several hours later. First aid must be provided immediately after signs of intoxication appear.

Classification

Highlight the following types poisons:

  • Local poisons, which include substances that act only upon direct contact. These are mercury, arsenic, alkalis and acids.
  • Systemic poisons. After entering the body, they are sent through the blood to all organs. These are potassium cyanide, strychnine, hypnotics.
  • Chemical poisons, which are classified as acids, alkalis, salts, gases. These are various organic and inorganic compounds.

Poisons can also be household poisons, that is, they are found in the immediate environment of a person. These are paints, herbicides, insecticides, rat poisons and other substances. Therefore, when using such products, you must take precautions - wear a mask on your face and rubber gloves on your hands.

The most dangerous poisons

There is a list of the most dangerous poisons in the world. Moreover, their danger lies in various reasons:

  • Methyl alcohol. Such a substance, after entering the human body, causes intoxication. And if you drink it in large quantities, permanent blindness or even death is possible. Therefore, at the first symptoms of poisoning, the patient must be given assistance and taken to the hospital. The danger of such poison is that it appearance, the taste and smell are completely identical to ethyl alcohol, so they can be easily confused.
  • Mercury. It is contained in mercury thermometers. And if you break 2 thermometers in a room, then all the people in it will receive serious poisoning. The same substance is found in fluorescent lamps. Therefore, care must be taken when handling such items.

Mercury vapor is dangerous, and it begins to evaporate at room temperature. Therefore, if you break a thermometer or a lamp outdoors in winter, it’s not a big deal - the mercury balls can be collected and thrown away.

  • Snake poison. Approximately 250 species of snakes are venomous. However, the antidote for each type of reptile must be separate. This is the danger - after the poison enters the blood, the antidote must be administered as soon as possible, otherwise death will occur within 20 minutes - 4 hours (depending on the type of snake).
  • Potassium cyanide is the fastest-acting poison in the world. Moreover, you can be poisoned by it either by touching it or by inhaling it or if it gets in through the mouth. Under its influence, iron binds in blood cells, as a result of which the supply of oxygen to vital organs stops. Death occurs within a few minutes. The substance has the smell of bitter almonds. Neutralized by glucose, so ineffective in sweet environments.

Available poisons

One of the most available poisons are mushrooms. In the summer, when their season begins, many experience poisoning. Moreover, after eating some varieties of mushrooms, not only intoxication, but also death is possible. Therefore, without knowing the name of the mushroom, it is better not to take risks. You can only collect species that are definitely safe. Only one poisonous mushroom from a whole basket - and poisoning is guaranteed. These include false honey mushrooms, fly agarics, pale grebe and others. For example, there are several varieties of toadstool, and some of them are practically indistinguishable from edible mushrooms.

Fly agarics can also be edible if prepared correctly. They need to be boiled for 24 hours, draining the water as often as possible. But it’s better not to risk it and eat honey mushrooms, russula, boletus and other edible mushrooms.

Potatoes may also contain dangerous poisons for the human body. If potatoes are stored incorrectly (if they get sunlight on the root crop), solanine is formed in it. This substance causes severe intoxication in humans. It is not difficult to identify low-quality potatoes - as a rule, their skin takes on a greenish tint.

It is necessary to prepare bread only from flour purchased from trusted sources. It is not recommended to purchase it on the market. If the flour is contaminated with ergot, the baked bread will be poisonous, since the bacterium is not killed by heat treatment. Of course to fatal outcome such poison will not lead, but it will cause irreparable harm health.

At home, you can also easily become poisoned by chemical fertilizers. For example, potassium chloride is very dangerous because once it enters the bloodstream, the substance blocks the activity of the heart. Death occurs in just a few minutes.

Deadly poisons in nature

Scientists have compiled a list of poisons that, once ingested, have a high probability of death:

  1. A neurotoxin found in the venom of some snakes. Immediately after the bite, the victim becomes inactive and drowsy. But after a while, muscle cramps appear, breathing becomes more frequent. Death occurs within 20-30 minutes due to paralysis of the respiratory tract. Moreover, no hematomas or tumors appear at the site of the bite. However, such a snake bites very rarely. It is necessary to immediately administer the Anticobra antidote to the patient. If serious breathing problems are observed, ventilation is performed.
  2. Alpha-latrotoxin, which is contained in spider venom of the karakurt genus. At the moment of the bite, a burning sensation is observed, and after 20-30 minutes the pain spreads throughout the victim’s entire body. The patient’s well-being begins to improve within a few days, and after 2-3 weeks, his or her complete recovery occurs.
  3. An alpha-conotoxin found in the venom of some species of shellfish (eg, conus shellfish). If you take a shell with a mollusk in your hand, it immediately pierces it with spines. In this case, the victim feels unbearable pain, as a result of which he loses consciousness. After a few minutes, the heartbeat quickens, the fingers go numb, shortness of breath and paralysis of the limbs appear. Registered deaths after an injection of the geographic cone. Moreover, there is no antidote. The patient can only be saved with copious bloodletting from the injection site.
  4. Titutoxin, which is produced by the yellow fat-tailed scorpion. The poison is so toxic that it kills even an adult. It is with the bite of this scorpion that 95% of all deaths from this poison are associated. They are found in Africa and the Middle East. It is immediately necessary to administer Anti-Scorpion serum, which will help save the victim’s life.
  5. And finally, the deadliest poison in the world is diamphotoxin. This is the most powerful poison on our planet. Contained in the blood of the larvae of the leaf beetle, common in the area South Africa. The insect belongs to the same family as the Colorado potato beetle. The poison is intended only for protection from predators - after eating the beetle, it dies from excruciating pain. After entering the victim’s body, the poison reduces the hemoglobin content by approximately 75%, since red blood cells are intensively destroyed. Poison can only enter the human body through the mouth. There is no antidote.

All poisons are very dangerous and deadly, so if you need to come into contact with them, you need to do this with the utmost caution. If you notice symptoms of poisoning with toxic substances, you must urgently call an ambulance. In some cases, even minutes decide the outcome of the situation. Therefore, if the poison is very dangerous, it is necessary to take an antidote as quickly as possible. Otherwise, there is a high probability of death.

Poisons have been used from ancient times to the present day as weapons, antidotes, and even medicine.

In fact, poisons are found all around us, in drinking water, in household items and even in our blood.

The word "poison" is used to describe any substance that can cause a dangerous disorder in the body.

Even in small quantity, the poison can lead to poisoning and death.

Here are some examples of some of the most insidious poisons that can be fatal to humans.

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 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 bad canned food) and through open wounds.

2. Poison ricin


Ricin is natural poison which is 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 the fastest deadly poisons , known to mankind. It may be in the form of crystals and colorless gas with a bitter almond odor. 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 modern world it was 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 contained 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 receive it from the seeds of the chilibuha tree(Strychnos nux-vomica), native to India and South-East Asia. Although it is often used as a pesticide, it can also be found in narcotic substances such as heroin and cocaine.

The degree of strychnine poisoning depends on the amounts and route of entry into the body, but to cause serious condition, a small amount of this poison is enough. 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, seizures, 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.

#6 - Tetrodotoxin

This poison is found in blue-ringed octopuses and puffer fish(fugu).

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...
