Slow-acting poisons for humans. The most dangerous and deadly poisons in the world

Immense physical strength, powerful fangs and razor-sharp teeth are not the only weapons used in the animal kingdom. Thousands of animals use highly toxic poisons for attack or defense.

We present to your attention the ten most poisonous creatures in the world.

(Total 14 photos)

1. Box jellyfish

Main prize our top goes to Box Jellyfish ( Chironex fleckeri), which received this name because of its cubic shape. Over the past 60 years, this handsome man has claimed about 6 thousand lives. Its poison is considered the most deadly in the world, toxins affect the heart, nervous system and skin cells.

And, even worse, all this is accompanied by such hellish pain that the victims go into a state of shock and either drown or die from cardiac arrest. If you immediately treat the wound with vinegar or a solution of acetic acid, the victim has a chance, but, as a rule, vinegar cannot be found in water 😉

Box jellyfish can be found in sea ​​waters Asia and Australia.

2. King Cobra (Ophiophagus hannah)

The king cobra (Ophiophagus hannah) is the longest poisonous snake in the world, reaching 5.6 meters in length. Ophiophagus literally translates to "snake eater" because it eats other snakes. A single bite from this deadly snake can easily kill a person. She can even kill an adult asian elephant within 3 hours if the animal is bitten in a vulnerable area such as the trunk.

Among the representatives of snakes there are also more poisonous ones than the King Cobra, but it is capable of releasing much more poison than others. For example, 5 times more than the Black Mamba.
The king cobra is widespread in the dense mountain forests of the South and Southeast Asia.

3. Scorpio Leius quincestriatus

Contrary to popular belief, most scorpions are relatively safe for humans, since the stings only cause local effects (pain, anemia, swelling). However, the Leirus is a very dangerous species of scorpion because its venom is a powerful cocktail of neurotoxins that causes intense and unbearable pain, followed by fever, followed by coma, convulsions, paralysis and death.
Leiruses are common in North Africa and in the Middle East.

4. Taipan or Fierce Snake (Oxyuranus microlepidotus)

Just one taipan bite contains enough venom to kill 100 adult humans or an army of 250,000 mice. Its extremely neurotoxic venom is at least 200-400 times more poisonous than that of a common cobra. In just 45 minutes after a bite, an adult can die. But fortunately, there is an antidote, and besides, this snake is very timid and immediately crawls away at the slightest danger.
Lives in Australia.

5. Tree frogs or Poisonous frogs

If you ever manage to visit the rain forests of Central and South America, never touch the small, beautiful frogs - they can be extremely poisonous. For example, the size of the Golden Dart frog is only 5 cm, and the poison in it is enough to kill 10 adults.
In the old days, local tribes used the poison of these frogs to lubricate the tips of their arrows.

6. Blue Ringed Octopus (Australian Octopus)

The Blue Ringed Octopus is a small, golf ball-sized, but extremely venomous creature found in the coastal waters around Australia and slightly further north towards Japan. The blue-ringed octopus is usually light in color, with dark brown bands along its eight legs and body, with blue circles, added on top of these dark brown groups. When an octopus is disturbed or taken out of the water, it darkens and the rings become shiny and electric blue, and it is this color change that gives the animal its name.

Its poison is strong enough to kill a person. In fact, the octopus carries enough venom to kill 26 adults within a couple of minutes, and there is no antidote. If measures are not taken and treatment is not started, then the person begins to feel numbness, difficulty speaking, seeing, breathing problems arise, then complete paralysis and death occurs due to cardiac arrest and lack of oxygen.

7. Brazilian Wandering Spider (Phoneutria) or banana spider

This abomination was included in the Guinness Book of Records in 2007 for being guilty of the greatest number human deaths caused by spider bites. What is important is that these spiders are dangerous not only for their poison, but also for their behavior: they do not sit still and do not weave webs, they wander the earth, hiding in buildings, clothes, shoes, cars, anywhere; which significantly increases the risk of unexpectedly meeting them and being bitten.

8. Ball Fish or Puffer

Ball fish is the second most poisonous vertebrate animal on earth (the first is the Golden Dart frog from point 5). The meat of some subspecies, for example Fugu, is a delicacy in Japan and Korea, but the problem is that the surface of the fish and certain of its organs are very poisonous. The venom of fugu causes paralysis, resulting in suffocation and death from lack of oxygen.
Therefore, only licensed chefs are allowed to cook such fish in Japan.

9. Marbled Cone Snail

The marbled cone snail looks beautiful and very cute, but it can be just as deadly as any other animal on this list. A drop of its poison can kill 20 people. Signs of a bite: severe pain, swelling, numbness, and in serious cases, paralysis and respiratory failure. There is no antidote.

However, over the entire period, about 30 cases of human deaths from the poison of this snail have been recorded, which is not very much compared to other representatives of our list.

10. Stone fish

The stonefish may never win a beauty contest, but it will definitely win the Most Poisonous Fish award. The poison causes such unbearable pain that in search of salvation from suffering, victims wish to amputate the affected area. It is believed that the bite of a stone fish provokes severe pain, known to man. The pain is accompanied by shock, paralysis, and tissue death.

If you do not get immediate medical help, the outcome can be fatal.

Stonefish store their toxins in hideous dorsal ridges, which are designed to protect them from predators.
It is widespread in tropical waters The Pacific and Indian Oceans, from the Red Sea to the Great Barrier Reef.

In nature, there are a huge number of substances that, on the one hand, are dangerous to health, and on the other hand, help to cure various diseases. It all depends on their quantity and concentration. When exposed to poisons in sufficiently small quantities, some of them help to recover from the most dangerous diseases, without any pathologies or consequences.

The most powerful poison

Poisons are quite diverse: some kill a person instantly, while the effects of others are very slow, gradually leading to death for the body. Some even cause severe pain and terrible suffering. There are a huge variety of them; the article lists the most dangerous ones. So dangerous that it is difficult to even determine which poison is the strongest.

Cyanide

Hydrocyanic acid and its derivatives are a very dangerous substance for the human body. A very small amount of it can instantly kill a living organism. However, sugar can resist it; it is an antidote.

Anthrax poison

The bacteria that cause this life-threatening disease belong to the Bacillus anthracis family. They attack healthy cells, leading to their death. If a person has cutaneous form disease, then in 20% leads to death. When affected by intestinal anthrax, 50% of victims die. The pulmonary form leaves virtually no chance for the patient to survive; doctors manage to save only 5%.

Sarin

This substance was obtained as a result of attempts to synthesize pesticides. It is very dangerous; when it enters the body, a person experiences severe suffering, which ultimately leads to death. This poison for a long time was used as a chemical weapon until its production was stopped in the 90s. But at present it is still used by terrorists and the military.

Amatoxins

These substances are contained in fly agaric mushrooms. A person can only feel symptoms after poison enters the body only after 10 hours or even the next day. Amatoxins have a detrimental effect on all organs, so in most cases poisoning is fatal. If a person managed to survive, then for the rest of his life he will be tormented by pain that arises due to internal organs damaged by these substances.

Mercury

This poison penetrates everything internal organs person. tends to accumulate, so with a small amount of it it very slowly poisons the body. When a person is poisoned by this substance, the normal functioning of the nervous system is disrupted and a severe mental disorder occurs.

Strychnine

It was discovered by chemists back in the 19th century. This toxic substance is obtained from chilibuha nuts. A large amount of it leads to severe poisoning. Subsequently, a slow death occurs, while the person suffers greatly and begins to have convulsions. If used in small quantities, strychnine is an excellent remedy for treating paralysis. One more thing useful property The fact is that this substance speeds up metabolism.

Tetrodotoxin

This poison is found in a Japanese fish called fugu. Its content has also been noted in the caviar and skin of animals that live in water in tropical zone, and its presence has also been recorded in the eggs of the Californian newt. Doctors are not always able to cure a person after ingesting this poison, and the mortality rate is high. However, most people still prefer to try this delicacy - fugu dishes. But even the most experienced chef is not immune to the fact that the fish he cooks will poison his visitors.

V-Ex

This poison is used by the military as a chemical weapon. It paralyzes the human body and also causes nervous breakdown. If a person inhales its vapors, or the substance gets on the skin, then painful death occurs in less than an hour.

Ricin

Obtained from plants. Its grains are very dangerous; if they enter the respiratory tract, they endanger human life. He dies if this substance enters the blood. Very powerful, stronger than even cyanide, and only due to technical problems it was not possible to use it as a chemical weapon mass destruction. But still, this poison is used by the military and terrorists.

Botulism toxin

Produced bacterial cells Clostridium botulinum, which are very dangerous to human health and life. When exposed to them, the body develops botulism. This poison is widely used in medicine: it is added in small quantities to medications, and it is also widely used in operations in which Botox is used. Perhaps botulinum toxin is the most powerful poison for humans.

The poisons described in the article have a detrimental effect on the body, causing death in most cases. And if the victim is able to be saved from intoxication with these substances, then for the rest of his life he will experience various consequences and health problems.

Let's start with the “king” of poisons – Arsenic. Until 1832, arsenic poisoning was extremely difficult to diagnose, since the symptoms of poisoning with this poison were similar to those of cholera. This similarity made it possible to mask the use of arsenic and its compounds as a deadly poison.

In acute arsenic poisoning, vomiting, abdominal pain, diarrhea, and depression of the central nervous system are observed.

Antidote: aqueous solution of sodium thiosulfate, dimercaprol.

Cyanide

Potassium cyanide, or potassium cyanide, is the most powerful inorganic poison. It looks like granulated sugar.

When it enters the body, the cells stop absorbing oxygen, resulting in the body dying from interstitial hypoxia. Potassium cyanide is absorbed very quickly and therefore death occurs within 15 minutes.

Sarin gas

Sarin gas is a poisonous substance with a nerve-paralytic effect.

The first signs of exposure to sarin include nasal discharge, chest congestion, and constriction of the pupils. Soon after this, the victim has difficulty breathing, nausea and increased salivation. The victim then completely loses control over bodily functions. This phase is accompanied by convulsions. Ultimately, the victim falls into a comatose state and suffocates in a fit of convulsive spasms followed by cardiac arrest.

Antidote: Atropine, Pralidoxime, Diazepam, Athens.

Diamphotoxin

Diamphotoxin is the most powerful poison of animal origin on our planet, contained in the blood of the larvae of the South African leaf beetle.

It is capable of reducing the hemoglobin content in the blood by 75% in a short period of time due to the massive destruction of red blood cells.

Antidote: There is no specific antidote.

Ricin

Ricin is the most powerful poison plant origin, which is obtained from the castor beans of the castor bean plant.

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, low blood pressure, hallucinations and seizures. Death can occur within 36-72 hours.

Antidote: There is no specific antidote.

October 7th, 2009

If you want to be healthy, douse yourself, don’t touch this rubbish, or better yet, avoid it altogether...
The deadliest things on our planet.

Pale grebe- Destroying Angel. The first physical signs of poisoning are usually nausea, vomiting, and bloody diarrhea. After feeling a slight discomfort, there is a sharp pain in the abdomen, severe vomiting, intense thirst, and cyanosis of the extremities, as well as yellowness of the eyes and skin as liver damage. The patient remains conscious almost until the end, with brief intervals of loss of consciousness, then coma and death.

Dog fish(Pufferfish). The poison tetraodontoxin is found in the ovaries of this fish and is not destroyed by heat treatment. In case of poisoning, speech is difficult, and paralysis of the respiratory system quickly develops, accompanied by paralysis of the central nervous system. The cause of death is most often convulsions or respiratory arrest, which occur within one to two hours after the poison enters the body.

Castor bean-Castor Beans. Signs of poisoning are bitterness in the mouth, nausea, vomiting, convulsions, drowsiness, cyanosis, stupor, impaired microcirculation, blood in the urine, ultimately coma, and death; the toxic agent, even in low concentrations, causes the dissolution of red blood cells; in serious cases, hemorrhages develop throughout the body. Castor beans can also lead to premature birth in pregnant women. Autopsies of patients who have died from castor bean poisoning show that the vomit and stool contain blood.

Belladonna. All parts of the plant are deadly poisonous, especially its roots, leaves, and berries. The poison paralyzes the parasympathetic nervous system by blocking nerve endings.

Viper Venom. Snake venom affects the blood and nervous system, it is less poisonous when it enters the mouth than into the blood... The victim of a viper bite bleeds from the wound, has a fever and chills. Poisoning is accompanied by swelling or hemorrhages above the elbows or knees. These signs usually appear within two hours after the bite. Then fainting, bleeding from the nose and mouth, loss of vision, followed by loss of consciousness. Death caused by cardiorespiratory disorders is inevitable if an antidote is not administered in time.

Barbados nut or Physical nut. The threat lies in the deceptively pleasant taste of the seeds. However, make no mistake - each seed contains at least 55 percent of the active substance "Hell oil", which blocks protein synthesis in the intestinal wall and can lead to death.

Hemlock. Signs of poisoning are a gradual loss of coordination, accompanied by a fast and weakened pulse, pain in the muscles as they atrophy and eventually die. Although the mind remains clear, vision often deteriorates until the victim succumbs to pulmonary paralysis. It is believed that Socrates was poisoned with the juice of this plant, and not hemlock, as previously thought.

Cobra Venom has mainly neurotoxic effects. Its strength is enough to cause the death of a person after the first full bite. In such cases, the mortality rate may exceed 75 percent. However, taking into account all the behavioral features king cobra Overall, only 10 percent of bites are fatal to humans.

Datura. All parts of the plant contain poisonous alkaloids. If it enters the gastrointestinal tract, it affects the nervous system, causing cardiac dysfunction and paralysis.

Lily of the valley. Contains a cardiac glycoside in a fairly high concentration, in small doses it stimulates the work of a weakened heart muscle, but in case of an overdose it leads to arrhythmias and blockade of the electrical conductivity of the heart, necessary for its normal contractions. All parts of the plant are poisonous. Poisoning manifests itself as nausea, vomiting, diarrhea, severe headache pain and pain in the epigastric region. In severe cases, the rhythm and frequency of heart contractions are disturbed, and the pulse, as a rule, becomes rare. Sometimes the nervous system is also affected. This is evidenced by agitation, visual disturbances, convulsions, and loss of consciousness.

Aconite has neurotoxic and cardiotoxic effects. Symptoms of poisoning are nausea, vomiting, numbness of the tongue, lips, cheeks, tips of fingers and toes, a crawling sensation, sensations of heat and cold in the extremities. Intoxication with aconite is characterized by a transient visual disturbance - the patient sees objects in green. There is also drooling, followed by dry mouth, thirst, headache, anxiety, convulsive twitching of the muscles of the face and limbs, and loss of consciousness. Breathing is rapid, shallow, and may suddenly stop.

Rhododendron. Contains glucoside substances - andromedotoxin, ericoline. Andromedotoxin has a local irritant and general narcotic effect, first stimulating and then depressing the central nervous system; greatly upsets the activity of the heart, in a peculiar way, like veratrine, it affects the muscle. Poisoning develops very quickly. Often, within a few hours of eating rhododendron leaves and branches, death occurs.

Tubocurarine chloride. White crystalline powder, in traumatology d-tubocurarine is sometimes used to relax muscles when repositioning fragments, reducing complex dislocations... Side effects from the use of tubocurarine are observed only in case of an overdose; in this case, the patient may develop respiratory failure due to paralysis of the respiratory muscles and, as a result, death.

Rhubarb. Rhubarb can only be eaten in early spring, until the air temperature rises above 15-17° C. In early spring, malic acid predominates in rhubarb, then its content increases, and as the temperature rises in hot weather, oxalic acid accumulates in the petioles, which is harmful to the body: it forms poorly excreted salts and removes calcium contained in the blood. Consumption of oxalic acid in an amount of 3-4 g at once is dangerous not only for children, but also for adults. In case of poisoning, vomiting, convulsions, and kidney failure may occur. In the first two days, death can occur from asphyxia, shock, or cardiovascular failure. In the next 2 weeks after poisoning, severe complications such as acute renal failure, repeated collapses, profuse bleeding, hemorrhagic pneumonia, and gastric perforation may occur, which can lead to death.

Gila monster - large reptile, with a very beautiful black and orange pattern all over the body. The Latin name for this beautiful lizard- Heloderma suspectum or poison tooth. There are grooves on the upper and lower jaws, into which the channels of highly developed poisonous glands approach. When biting, the teeth go deep into the victim's body. Venom tooth bites are very painful and act almost the same as snake bites. The venom is neurotoxic, that is, when it bites, it paralyzes its victim. For small animals, the lizard's venom is fatal; in humans it usually causes very severe swelling, but can sometimes lead to death.

Croton oil- liquid obtained from the seeds of the Croton tiglium plant. It has a strong laxative effect and irritates the skin and mucous membranes. Even in small quantities (over 20 drops) it is life-threatening. Crotonal is toxic and mutagenic. When a person inhales its vapors, irritation of the mucous membrane, pharyngitis, cough, chest pain, nausea, vomiting, and the onset of shock or unconsciousness occurs. Contact directly with the liquid results in severe skin redness, irritation, pain and burns. When poison gets inside, the whole body is poisoned, the central nervous system is damaged, and tumors form. In case of tactile contact, skin scarring occurs.

Digitalis. Nowadays, digitalis purpurea is used to produce medicines that stimulate work. cardiovascular system. Active biological substances from digitalis tend to accumulate in the body and can be harmful or even fatal to a person with a healthy heart. The grass and rhizomes of foxglove are saturated with the toxin digitalin. Poisoning is accompanied by irritation of the gastrointestinal tract, the pulse becomes rapid and arrhythmic, and general weakness and shortness of breath are observed. Convulsions may develop before death.

Codeine is an almost clear, odorless substance with a rather bitter taste, which is available in either powder or liquid form. When used in high doses, like other opiates, it can cause euphoria. Serious poisoning is often possible when taking a large number of tablets of some codeine-containing medications. Due to the fact that with regular use of codeine, an addictive phenomenon is observed (similar to addiction to heroin and other drugs of the opiate group), it is released with the same restrictions as other narcotic analgesics. In case of severe codeine poisoning, breathing disorders are possible, up to paralysis with preserved consciousness, as well as a significant fall blood pressure.

Poisonous octopus(blue ringed octopus). Its venom, which belongs to the group of neurotoxins, is so powerful that it can kill an adult, especially if the octopus bites in the neck or in the area close to the spine. There is simply no vaccine for its poison

Dimethyl sulfate. Used in the manufacture of paints, drugs, perfumes and pesticides, most poisonings from dimethyl sulfate occur due to leakage of liquid or vapor. Signs of poisoning will be more pronounced if alcohol is present. Nausea, vomiting, weakness, dizziness, and headache occur. Possible increase in temperature, excitability, pain in the limbs, visual and hearing impairment, mental disorders. In severe cases, tremor, ataxia, loss of consciousness, paroxysmal clonic-tonic convulsions resembling epileptic seizures, and coma develop. A pathological examination reveals pronounced vascular disorders and degenerative changes in the parenchymal organs, brain and adrenal glands.

Nicotine. It is estimated that lethal dose nicotine for humans is 1 mg per 1 kg of body weight, i.e. about 50 - 70 mg for a teenager. Consequently, death can occur if a teenager smokes half a pack of cigarettes at the same time, because a whole pack contains exactly one lethal dose of nicotine.

Wart. A fish with a row of spines on its back that release a poisonous toxin. This is the most dangerous known poisonous fish and its venom causes extreme pain with possible shock, paralysis and tissue death depending on the depth of penetration. At the slightest irritation, the wart raises the spines of the dorsal fin; sharp and durable, they easily pierce the shoes of a person who accidentally steps on a fish, and penetrate deep into the foot. With deep penetration, the injection can be fatal to a person if he is not provided medical care within a few hours. If the thorn gets into a large blood vessel, death can occur within 2-3 hours. Survivors sometimes remain ill for months. The venom consists of a mixture of proteins, including hemolytic stonustoxin, neurotoxin and cardioactive cardioleptin. Typically, surviving victims suffer localized nerve damage, sometimes leading to atrophy of the attached muscle tissue. The pain can be so severe that injection victims want to cut off the injured limb.

Hydrogen sulfide- a colorless, poisonous gas heavier than air with an unpleasant odor of rotten eggs. It can be released during the process of decay and accumulates in lowlands. Very toxic. At high concentrations, a single inhalation can cause instant death. At low concentrations, adaptation to unpleasant smell“rotten eggs”, and it ceases to be felt. A sweetish metallic taste appears in the mouth. The first symptom of acute poisoning is loss of smell. Subsequently, headache, dizziness and nausea appear. Sometimes, after a while, sudden fainting occurs.

Oleander- a large evergreen shrub. All parts of the plant are poisonous, moreover, the smoke from the burning plant and the water in which the flowers stood are poisonous. The plant contains a number of cardiac glycosides (oleandrin, cornerin, etc.). Oleander juice, taken internally, causes severe colic in humans and animals, vomiting and diarrhea... It also affects the nervous system (even to the point of coma). Cardiac glycosides cause cardiac arrest.

Phencyclidine(phencyclidine, PCP) - widely used in veterinary medicine for short-term immobilization of large animals. It has been noted to cause dissociated anesthesia. Phencyclidine is easy to synthesize. People who use phencyclidine are primarily young people and polydrug addicts. The true prevalence of phencyclidine drug addiction is unknown, but national data suggests that cases in the United States are lately have become more frequent. PCP is either taken orally, smoked, or administered intravenously. It is also used as an additive to illegally sold delta-tetrahydrocannabinol, LSD and cocaine. The most common homemade drug of PCP is called "angel dust." Low doses of phencyclidine (5 mg) cause restlessness, agitation, incoordination, dysarthria, and anesthesia. Horizontal and vertical nystagmus, hot flashes, profuse sweat, and hyperacusis are also possible. Mental disorders include disruption of body schema, incoherent thinking, derealization, and depersonalization. Higher doses (5-10 mg) cause increased salivation, vomiting, myoclonus, hyperthermia, stupor and coma. In doses of 10 mg or more, phencyclidine causes epileptic seizures, opisthotonus and decerebrate rigidity, which can be followed by prolonged coma. Acute psychosis caused by phencyclidine should be considered a psychiatric emergency with high risk suicide or violent crimes.

Parathion(Parathion) - organophosphorus compound - pesticide; when it is inhaled, enters the gastrointestinal tract, or is absorbed through the skin, poisoning occurs. Like some other organophosphate compounds, parathion interferes with the enzyme cholinesterase, resulting in excessive stimulation of the parasympathetic nervous system. Symptoms of poisoning include headaches, profuse sweating and salivation, lacrimation, vomiting, diarrhea and muscle spasms.

TEPP cholinesterase inhibitor-used mainly as insecticides and can cause poisoning. Symptoms include headache, loss of depth perception, convulsions, sweating, chest pain, shortness of breath, vomiting, general paralysis, involuntary urination and defecation, drop in blood pressure, death.

Yew tree. All parts of the plant are poisonous, except the red fruits. The wood, bark and leaves of yew contain the alkaloid taxin and are therefore poisonous to humans and many other animals, although, for example, hares and deer eat yew willingly and without harm to themselves. The older the yew needles, the more poisonous they are.

Carbon Tetrachloride(Carbon Tetrachloride) is a caustic volatile liquid used as a dry cleaner. When its vapors are inhaled or swallowed, it causes severe damage to the heart, liver and kidneys (for example, the patient may develop cirrhosis of the liver or kidney nephrosis), affects the optic nerve and some other nerves in the human body.

Strychnine- an alkaloid found in seeds tropical plants genus strychnos. It has a stimulating effect on the central nervous system, and in toxic doses causes characteristic tetanic convulsions...

Clostridium botulinum(Clostridium botulinum) is a gram-positive bacterium of the genus Clostridium, the causative agent of botulism, a severe food intoxication caused by botulinum toxin and characterized by damage to the nervous system. Botulinum toxin accumulates in food products, infected with C. botulunum spores during their germination, if anaerobic conditions are created (for example, during canning). For humans, botulinum toxin is the most potent bacterial poison, having a detrimental effect at a dose of 10-8 mg/kg. C. botulinum spores can withstand boiling for 6 hours, high pressure sterilization destroys them after 20 minutes, 10% hydrochloric acid after 1 hour, 50% formaldehyde after 24 hours. Botulinum toxin type A(B) is completely destroyed when boiled for 25 minutes. The incubation period for botulism ranges from several hours to 2-5 days (rarely up to 10 days). On the first day, nausea, vomiting, and diarrhea are noted. Further, neurosymptoms associated with damage to nerve centers predominate: impaired accommodation, double vision, difficulty swallowing, aphonia. In severe forms of botulism, death occurs from respiratory paralysis, sometimes from sudden cardiac arrest.

Potassium cyanide- potassium salt of hydrocyanic acid, chemical formula KCN. Strong inorganic poison. When hit through digestive tract lethal dose for humans is 1.7 mg/kg. Sometimes large doses are tolerated; the effect may be slowed down when the stomach is filled with food. Potassium cyanide is a potent inhibitor. When it enters the body, it blocks the cellular enzyme cytochrome c oxidase, as a result of which cells lose the ability to absorb oxygen from the blood and the body dies from interstitial hypoxia.

The Swiss physician and alchemist Paracelsus famously said: “All substances are poisons; there is not one that is not. The right dose makes the difference between the poison,” and he’s right. Even the water is too large quantities will kill you. However, some substances require very small amount to cause death - sometimes all it takes is 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 real 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 for it to have a negative effect. 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 thing 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 is a very poisonous herb (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 Carbon monoxide poisoning is 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. IN natural form it is found in several plant species in Africa, Brazil and Australia. The terrible truth The thing about this deadly, odorless and tasteless poison 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.

17. The most dangerous man-made poison is called dioxin, and it only takes 50 micrograms to kill an adult. It is the third most toxic poison known to science, 60 times more toxic than cyanide.

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's whole family, which includes more than 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. 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 destroy 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 very unpleasant way die, for both man and rat.

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 idea. 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.

2. Ricin is more lethal than anthrax. This substance is obtained from the castor bean, the same plant from which we obtain castor oil. This poison is especially toxic if inhaled, and a pinch of it will kill you very quickly.

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.
