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

In fact, poisons are all around us, in drinking water, in everyday objects and even our blood.

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

Even in large quantities, 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 fatal small doses, so it’s 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 serious illness, 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 a natural poison. 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 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 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 gas when 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.

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, 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 paralysis occurs respiratory system, the heart can 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 neurotoxins 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.

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 quantities, the poison can lead to poisoning and death.

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.

It kills by binding to iron in blood cells, making them unable to carry oxygen.

6. Mercury and mercury poisoning

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.

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 drugs such as heroin and cocaine.

8. Arsenic and arsenic poisoning

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.

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.

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.

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.

The Swiss physician and alchemist Paracelsus famously said: “All substances are poisons; there is not a single one that is not. The right dose makes the difference between the poison,” and he’s right. Even too much water will kill you. However, some substances require very small amounts to cause death - sometimes just enough for a drop to fall on a gloved hand - which is why they initially fell into the class of poisons. From flowers to heavy metals, from man-made gases to actual poison, here are the 25 most dangerous poisons known to mankind.

25. Cyanide can be in the form of a colorless gas or crystals, but in either case it is quite dangerous. It smells like bitter almonds, and once ingested, it can cause symptoms such as headache, nausea, rapid breathing and increased heart rate, and weakness in just a few minutes. If left untreated, cyanide kills because cells are deprived of oxygen. And yes, cyanide can be obtained from apple seeds, but don't worry if you eat a few. You will need to eat about ten kernels before you have enough cyanide in your body to have any effect. Negative influence. Please don't do this.

24. Hydrofluoric acid (Fluoric acid) is a poison used, among other things, in the production of Teflon. In its liquid state, this substance can easily seep through the skin into the bloodstream. In the body, it reacts with calcium and can even destroy the underlying bone. The scary part is that the contact doesn't cause any pain at first, leaving more time and opportunity for serious damage to occur.

23. Arsenic is a naturally occurring crystalline semimetal and perhaps one of the best known and most common poisons used as a murder weapon in the late 19th century. However, its use for such purposes began in the mid-1700s. Arsenic poisoning can cause death within hours or days. Symptoms of poisoning include vomiting and diarrhea, which made it difficult to distinguish arsenic poisoning from dysentery or cholera 120 years ago.

22. Belladonna or Deadly Nightshade - very poisonous grass(flower) with a very romantic story. What makes it poisonous is an alkaloid called atropine, and the entire plant is poisonous, with the root containing the most poison and the berries the least. However, even two eaten are enough to kill a child. Some people use belladonna for relaxation as a hallucinogen, and in Victorian times women would often drop belladonna tincture into their eyes to dilate their pupils and make their eyes sparkle. Before you die under the influence of belladonna, you may experience a seizure, increased heart rate, and confusion. Don't play with belladonna, kids.

21. Carbon monoxide (carbon monoxide) is an odorless, tasteless, colorless substance and slightly less dense than air. It will poison and then kill you. Part of what makes carbon monoxide so dangerous is that it is difficult to detect; sometimes called the "silent killer". This substance prevents the body from delivering oxygen to where it is needed, such as to cells, to keep them alive and functioning. Early symptoms of carbon monoxide poisoning are similar to the flu without fever: headache, weakness, drowsiness, lethargy, insomnia, nausea and confusion. Luckily, you can purchase a detector carbon monoxide in almost every specialty store.

20. The deadliest tree in all North America grows in Florida. Otherwise, where else would he grow? The Manchineel tree or Beach apple tree has small green fruits that look like apples and look like they would taste sweet. Don't eat them. And don't touch this tree. Don't sit next to it or under it, and pray you never end up in the wind under it. If the sap gets on your skin, it will blister, and if it gets in your eyes, you may go blind. The juice is contained in both the leaves and the bark, so do not touch them. Probably, the juice of this plant killed the conquistador Ponce de Leon, who discovered Florida.

19. Fluorine is a pale yellow gas that is highly poisonous, corrosive and will react with almost anything. For fluorine to be lethal, a concentration of 0.000025% is sufficient. It causes blindness and asphyxiates the victim like mustard gas, but its effects are much worse.

18. The pesticide used is Compound 1080, also known as sodium fluoroacetate. It is found naturally in several plant species in Africa, Brazil and Australia. The scary truth about this deadly poison odorless and tasteless is that there is no antidote for it. Oddly enough, the bodies of those who die from ingesting this poison remain poisonous for a whole year.

16. Dimethylmercury (a neurotoxin) is a terrible poison because it can penetrate most standard protective equipment, such as thick latex gloves. This is exactly what happened to a female chemist named Karen Wetterhahn in 1996. A single drop of colorless liquid fell on my gloved hand, and that was it. Symptoms began to appear FOUR MONTHS later, and six months later she was dead.

15. Wolfsbane (Fighter) also known as "Monk's Hood", "Wolfsbane", "Leopard's Venom", "Women's Curse", "Devil's Helm", "Queen of Poisons" and "Blue Rocket". In fact, it is an entire genus of over 250 herbs, and most of them are extremely poisonous. The flowers can be either blue or yellow, and while some of the plants are used for traditional medicine, it has also been used as a murder weapon over the past decade.

14. The toxin found in poisonous mushrooms is called amatoxin. It attacks liver and kidney cells and kills them within a few days. Sometimes it also affects the heart and central nervous system. Treatment is available, but results are not guaranteed. The poison is temperature stable and cannot be removed by drying. So unless you are 100% sure they are safe, don't eat mushrooms.

13. Anthrax is actually caused by a bacterium called Bacillus anthracis. What makes you sick is not so much the bacteria, but the toxin they produce when they enter the body. Bacillus Anthracis can enter your system through the skin, mouth, or respiratory tract. The mortality rate from airborne anthrax reaches 75% even with treatment.

12. Hemlock plant - classic poisonous plant, which was regularly used for executions in Ancient Greece, including for the philosopher Socrates. There are several varieties, and in North America, water hemlock is the most common plant. You could die from eating it, but people still do it, thinking hemlock is a perfectly acceptable salad ingredient. Water hemlock causes painful and severe convulsions, cramps and tremors. Those who survive may subsequently suffer amnesia or other long-term problems. Water hemlock is considered the deadliest plant in North America. Serious note: Supervise your children, even older ones, when they are outside. Don't eat anything unless you are 100% sure it is safe.

11. Strychnine is commonly used to kill small mammals and birds, and is often the main ingredient in rat poison. In large doses, strychnine can also be fatal to humans. It can be swallowed, inhaled, or enter the body through the skin. The first symptoms: painful muscle cramps, nausea and vomiting. Muscle contractions ultimately lead to suffocation. Death can occur within half an hour. This is a very unpleasant way to die, for both humans and rats.

10. Most of those who understand such things consider maytotoxin to be the most powerful marine toxin. It's found in a dinoflagellate algae called Gambierdiscus toxicus, and if those words confuse you, just think of deadly plankton to get the point across. For mice, meiototoxin is the most toxic among non-protein toxins.

9. Mercury, the silvery liquid in old school thermometers, is a heavy metal that is quite toxic to humans if inhaled or touched. If you touch it, it can cause your skin to peel off, and if you inhale the mercury vapor, it will eventually shut down your central nervous system and you will die. Before then, you are likely to experience kidney failure, memory loss, brain damage and blindness.

8. Polonium is radioactive chemical element and has been implicated in the deaths of everyone from Yasser Arafat to Russian dissidents. Its most common form is 250,000 times more toxic than hydrocyanic acid. It is radioactive and emits alpha particles (they are not compatible with organic tissues). Alpha particles cannot penetrate the skin, so polonium must be ingested or injected into the victim. However, if this happens, the result will not be long in coming. One theory is that a gram of polonium 210 could kill up to ten million people if injected or ingested, causing first radiation poisoning and then cancer.

7. Suicide tree or Cerbera odollam acts by disturbing the natural rhythm of the heart and often causing death. A member of the same family as Oleander, the plant was often used to perform the "innocence test" in Madagascar. An estimated 3,000 people a year died from drinking Cerberus poison before the practice was outlawed in 1861. (If you survived, you were found innocent. If you died, it didn't matter because you were dead).

6. Botulinum toxin is produced by the bacterium Clostridium Botulinum, and it is an incredibly powerful neurotoxin. It causes paralysis, which can lead to death. You may know botulinum toxin by its commercial name, Botox. Yes, that's what the doctor injects into your mom's forehead to make it less wrinkled (or into her neck to help with migraines) to cause muscle paralysis.

5. Pufferfish is considered a delicacy in some countries, where it is called Fugu; it's a dish that some would literally die for. Why? Because the insides of the fish contain tetrodotoxin, and in Japan, approximately 5 people a year die from eating puffer fish as a result of improper preparation technology. But gourmets continue to persist.

4. Sarin gas will give you the opportunity to survive the worst moments of your life. Your chest tightens, tighter, tighter, and then... it relaxes because you are dead. Although Sarin was outlawed in 1995, it has not stopped being used in terrorist attacks.

3. Golden Poison Arrow Frog - Tiny, adorable and quite dangerous. Only one frog is the size of the end of your thumb contains enough neurotoxin to kill ten people! A dose equal to about two grains of salt is enough to kill an adult. This is why some Amazon tribes used poison to coat the tips of their hunting arrows. One touch of such an arrow will kill you within minutes! Here's a great rule: if you see a frog and it's yellow, blue, green or red, don't touch it.

1. Codenamed “Purple Possum”, a VX gas, is the most powerful nerve gas on Earth. It is entirely man-made and we can thank the United Kingdom for that. It was technically banned in 1993, and the US allegedly destroyed its stockpile. Other countries are “working on it.” Which we should trust completely because governments are known to be 100% honest about these things.

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. Most famous case Applications - Emperor Claudius poisoned his wife Agrippina by adding aconite to her mushroom dish.

Source: wikipedia.org

#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.

Source: wikipedia.org

#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 injecting it 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...

Source: wikipedia.org

#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

elemental mercury - found in thermometers. Instant death occurs if inhaled;
inorganic mercury - used in the manufacture of batteries. Lethal if swallowed;
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.
