Poison that is possible. The fastest-acting deadly poisons for humans - pharmaceutical, household

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 quickly develops respiratory system 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 is manifested by nausea, vomiting, diarrhea, severe headache pain and pain in the epigastric region. In severe cases, the rhythm and frequency of heart contractions are disrupted, 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 during reposition of fragments, reduction of complex dislocations... Side effects from the use of tubocurarine are observed only with its overdose; in this case, the patient may develop respiratory failure due to paralysis of the respiratory muscles and, as a consequence, 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- a large reptile, with a very beautiful black and orange pattern throughout 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, meaning that 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 the lethal dose of 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 venomous fish known 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 body schema disturbance, 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 a high risk of 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 organophosphorus 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 - 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 hydrocyanic acid, chemical formula KCN. Strong inorganic poison. When ingested through the digestive tract, the 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 powerful 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.

Some animals have the amazing ability to kill using toxic substances. chemical compounds, or poison. This method is considered one of the most cowardly, insidious and effective. In this article, you will discover 11 poisonous animals in the world that can easily kill an adult.

There are "passively" venomous animals (which transmit their venom by being eaten or attacked by other animals) and "actively" venomous (which inject venom into their victims using stingers, fangs or other devices.

The most poisonous amphibian: The terrible leaf climber

It lives only in the tropical rainforests of western Colombia. The poison of one frog can kill from 10 to 20 people. (Only one type of snake Liophis epinephelus, resistant to poison terrible leaf climber, however, if exposed to a large enough amount of the toxin, the reptile may die).

Interestingly, the terrible leaf climber produces its poison from its diet of native ants and beetles; specimens kept in captivity and feeding on fruit flies and other common insects are completely harmless.

Most poisonous spider: Brazilian wandering spider

If you suffer from arachnophobia (fear of spiders), there is good and bad news for you about the Brazilian wandering spider. The good news is that these spiders live in tropical South America, and do not always inject a full dose of poison during a bite, and also rarely attack people; The even better news is that an effective antidote (if administered quickly) can prevent death. Bad news is that the spider's venom contains powerful neurotoxins that slowly paralyze and suffocate its victims, even in microscopic doses.

Men bitten by Brazilian wandering spiders often experience painful erections.

Most Poisonous Snake: McCoy's Taipan

The venom of this Australian snake is the most powerful among land snakes. Toxic substances contained in one individual can kill hundreds of adults. (Its venom is made up of neurotoxins, hemotoxins, mycotoxins, and nephrotoxins. This means it can dissolve your blood, brain, muscles, and kidneys before you hit the ground.) Fortunately, this venomous snake rarely comes into contact with humans. and even when this happens (if you know how to interact with her), she becomes quite meek and easily tamed.

The most poisonous fish: Wart

This fish lives in shallow waters in the South Pacific Ocean. It looks ominously like a rock or piece of coral (the camouflage is meant to ward off predators) and if stepped on, the wart injects a powerful dose of toxins into the person's foot.

Australian authorities are actively replenishing supplies of antidotes, so there is a high probability of saving lives (provided that the antidote is administered in a timely manner).

Most Poisonous Insect: Maricopa Ant

Maricopa Ants ( Pogonomyrmex maricopa) quite dangerous insects. About 300 bites of these ants can cause death in an adult. Their venom is much stronger than that of hornets and honey bees. One bite of such an ant causes acute pain that lasts about 4 hours.

Fortunately, it is virtually impossible to accidentally step on a Maricopa ant colony and end up getting stung by hundreds; These insects are known to build nests with a diameter of about 9 m and a height of up to 2 m!

The most poisonous jellyfish: Sea wasp

Box jellyfish (jellyfish characterized by a rectangular bell shape) are by far the most dangerous invertebrate animals in the world, and the sea wasp ( Chironex fleckeri) is considered the most poisonous species of jellyfish on the planet. Tentacles sea ​​wasp covered with nematocytes - stinging cells, which, upon contact, cause burns.

Most people who come into contact with a sea wasp's tentacles experience excruciating pain, but a close encounter with this species can kill you in five minutes.

Most poisonous mammal: Platypus

Of course, platypus venom will not cause death to a person, but it will cause severe pain and swelling. Its poison is capable of killing small animals. On the hind limbs of males there are spurs (about 15 mm long) that contain poison. Most often, males use these spurs to fight each other during the breeding season.

Others poisonous mammals are: 3 species from the shrew family and the Cuban slittooth ( Solenodon cubanus).

The most poisonous mollusk: Marble cone

If you've never used the phrase "predatory sea snail," then you clearly don't know enough about the sea creatures that can kill you with a single bite. This mollusk is capable of paralyzing its prey (including other snails of the genus Conus) using a toxic poison that can easily kill an unwary person.

Unfortunately, no one has ever calculated how much poison can harm an adult.

Most poisonous bird: Bicolored blackbird flycatcher

The bicolored blackbird flycatcher from New Guinea contains a powerful poison called batrachotoxin. It is found in the skin and feathers of birds and can cause mild numbness and tingling in humans, but is much more dangerous for small animals. (Apparently, thrush flycatchers synthesize poison from beetles that are part of their diet (these beetles are also part of the diet of dart frogs).

Another famous poisonous bird is a common quail, the meat of which (if the bird has consumed a plant of a certain type) can lead to a non-fatal disease for humans called “coturnism”.

Most poisonous octopus: Blue-ringed octopus

Blue-ringed octopuses live in Indian and Pacific Oceans and have rather modest sizes (the largest individuals rarely exceed 20 cm). Their bite is almost painless, but the venom causes paralysis and can kill an adult within just a few minutes.

There is currently no antidote for blue-ringed octopus bites.

Most poisonous turtle: Hawksbill

Unlike some of the other animals on this list, the hawksbill turtle is not miniature: adults weigh about 80 kg, about the same as the average person. These turtles are distributed throughout the world, and individuals from Southeast Asia that eat toxic algae have poisonous meat that can cause poisoning in humans (symptoms of poisoning: nausea, vomiting, diarrhea, and other intestinal ailments).

These turtles are endangered and protected by law.

We present to your attention a list of the most famous poisons that have been used to kill people throughout history.

Hemlock is a genus of highly toxic flowering plants native to 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.

Fighter or Wolfsbane


Ninth place in the list of the most famous poisons is occupied 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.

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.


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.

Tetrodotoxin


Tetrodotoxin is found in two sea creatures - blue-ringed octopus and in 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.


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.


Mercury is a relatively rare element that at 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.


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.


Botulinum toxin is the most powerful poison known to science among 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.


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.

The Swiss physician and alchemist Paracelsus once correctly noted: “All substances are poisons; there is not a single one that is not. It’s all about the dose,” and he was absolutely right.

It’s paradoxical: the human body is almost 70% water, but even water in large quantities- destructive. However, sometimes even a drop of a substance is enough, which can be fatal. From flowers to heavy metals and gases produced by man himself; Below is a list of the most dangerous poisons known to mankind.

Cyanide exists in the form of a colorless gas or crystals, but in either case it is quite dangerous. It smells like bitter almonds, and when it enters the body, in just a few minutes it leads to symptoms such as headache, nausea, rapid breathing and increased heart rate, as well as weakness. If action is not taken promptly, cyanide kills by depriving the body's cells of oxygen. And yes, cyanide can be obtained from apple seeds, but don't worry if you eat a few. You will have to eat about ten apples before enough cyanide has accumulated in your body for you to feel all of the above. Please don't do this.

24. Hydrofluoric acid (Fluoric acid)


Hydrofluoric acid is a poison used, among other things, to make Teflon. In its liquid state, this substance easily seeps through the skin into the bloodstream. In the body, it reacts with calcium and can even destroy bone tissue. The worst thing is that the effect of contact does not appear immediately, which increases the likelihood of causing serious damage to health.


Arsenic is a naturally occurring crystalline semimetal and is perhaps one of the most well-known and common poisons used as a murder weapon in late XIX century. However, its use for such purposes began in the mid-1700s. The effect of arsenic lasts from several hours to several days, but the result is the same - death. 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

Belladonna or Deadly Nightshade is a highly poisonous herb (flower) with a romantic history. What makes it poisonous is an alkaloid called atropine. Absolutely the entire plant is poisonous, although to varying degrees: the root contains the most poison, and the berries contain less. However, even two pieces 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 death, under the influence of belladonna, a seizure develops, the pulse quickens and confusion occurs. Belladonna is not a toy for children.

21. Carbon monoxide (carbon monoxide)


Carbon monoxide (carbon monoxide) is an odorless, tasteless, colorless substance and slightly less dense than air. It poisons and then kills a person. Part of what makes carbon monoxide so dangerous is that it is difficult to detect; sometimes called the "silent killer". This substance prevents oxygen from entering the body for normal cell functioning. Early symptoms Carbon monoxide poisoning is similar to the flu without fever: headache, weakness, drowsiness, lethargy, insomnia, nausea and confusion. Fortunately, the detector carbon monoxide can be purchased at any specialty store.

20. Beach apple tree


The most dangerous tree in all North America grows in Florida. The Manchineel tree or Beach apple tree has small green fruits that look like sweet apples. Don't eat them! And don't touch this tree! Don't sit next to it and pray you never end up underneath it in windy weather. If the sap gets on your skin, it will blister, and if it gets in your eyes, you can go blind. The sap is contained in the leaves and bark, so don't touch them!


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

18. Sodium fluoroacetate


The pesticide used is Compound 1080, also known as sodium fluoroacetate. IN natural form it is found in some plant species in Africa, Brazil and Australia. The terrible truth of this deadly, odorless and tasteless poison is that there is no antidote for it. Oddly enough, the bodies of those who die from exposure to sodium fluoroacetate remain poisonous for a full year.


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

16. Dimethylmercury (neurotoxin)

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 chemist named Karen Wetterhan 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 she died six months later.

15. Wolfsbane (Wrestler)


Wolfsbane (Fighter) also known as "Monk's Hood", "Wolfsbane", "Leopard's Venom", "Women's Curse", "Devil's Helmet", "Queen of Poisons" and "Blue Rocket". This is practically an entire genus, which includes more than 250 herbs, most of which are extremely poisonous. Flowers can be either blue or yellow. Some of the plants were used not only in folk medicine, but also as a murder weapon over the past decade.


The toxin found in poisonous mushrooms is called amatoxin. It attacks liver and kidney cells and kills them within a few days. May affect 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. Therefore, if you are not 100% sure that the mushrooms you collect are safe, do not eat them.


Anthrax is actually a bacterium called Bacillus anthracis. What makes you sick is not so much the bacteria as the toxin it produces when it enters the body. Bacillus Anthracis can enter the system through the skin, mouth or respiratory tract. The mortality rate for airborne anthrax is as high as 75% even though there is a cure.

12. Hemlock plant


Hemlock - classic poisonous plant, which was regularly used for execution in Ancient Greece. There are several varieties, and in North America, water hemlock is the most common plant. You can die from eating it, yet people still add hemlock to salads, considering it an acceptable ingredient. Water hemlock causes painful and severe convulsions, cramps and tremors. People who have experienced the full power of the whitehead, but survive, may subsequently suffer from amnesia. Water hemlock is considered the deadliest plant in North America. Keep an eye on small children and even teenagers when they are outside! Don't eat anything unless you are 100% sure it is safe.

11. Strychnine


Strychnine is commonly used to kill small mammals and birds and is often a major component of rat poison. In large doses, strychnine is also dangerous for people. It can be swallowed, inhaled, or taken into 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.


Most knowledgeable people consider maytotoxin to be the most powerful marine toxin. It is found in a dinoflagellate algae called Gambierdiscus toxicus. For mice, meiototoxin is the most toxic among non-protein toxins.


Mercury is a heavy metal that is quite toxic to humans if inhaled or touched. Touching it can cause the skin to peel off, and if you inhale the mercury vapor, it will eventually shut down your central nervous system and be fatal. Before then, kidney failure, memory loss, brain damage and blindness are likely to occur.

8. Polonium


Polonium is radioactive chemical element. Its most common form is 250,000 times more toxic than hydrocyanic acid. It emits alpha particles (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 is injected into the body. could kill up to ten million people, causing first radiation poisoning and then cancer.


Suicide tree or Cerbera odollam works by disrupting 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 venom before the practice was made illegal in 1861. (If the person survived, he was found innocent. If he died, it no longer mattered.)


Botulinum toxin is produced by the bacterium Clostridium Botulinum and is an incredibly powerful neurotoxin. It causes paralysis, which can lead to death. Botulinum toxin is known 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) that causes muscle paralysis.

5. Pufferfish


Pufferfish is considered a delicacy in some countries, where it is called Fugu; it's a dish that few would literally die for. Why does death occur? 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

Sarin gas makes you relive the worst moments of your life. The chest shrinks, stronger and stronger, and then... death comes. Although the use of Sarin was made illegal in 1995, it has not stopped being used in terrorist attacks.

3. "Poison Arrow"


The Golden Poison Arrow Frog is tiny, adorable and very dangerous. Just one thumb-sized frog contains enough neurotoxin to kill ten people! A dose equal to about two crystals of salt is enough to kill an adult. This is why some Amazonian tribes used poison on the tips of their hunting arrows. One touch of such an arrow kills within a few minutes! When walking in the Amazon forests, stick to the rule: do not touch red, blue, green and especially yellow frogs.


Ricin is even more dangerous than anthrax. This substance is obtained from castor beans, the same plant from which castor oil is extracted. This poison is especially toxic if inhaled, and a pinch is enough to kill an adult.

1. "VX"


Codenamed "Purple Possum," the VX chemical is the most powerful nerve gas on Earth. It is man-made, and you can thank the United Kingdom for that. Technically, it was banned in 1993, and the US government allegedly ordered the destruction of its stock, but whether this is actually the case is anyone's guess.

It is difficult to determine the most powerful poison. This definition includes any substance that provokes serious pathological changes in the body. Poisons act in different ways. Some slowly and imperceptibly bring a person to a critical point, others cause unbearable pain.

You can predict the effect and take measures to eliminate serious consequences by finding out the exact cause of the poisoning. There is an antidote for each toxic substance.

Poisonous chemical origin

The most dangerous poisons are developed by humans. Not all were created as chemical warfare agents; for example, sarin was created as a result of the synthesis of pesticides. Its production stopped in the 90s of the 20th century.

The existing reserves were not destroyed, so this poison is used by terrorists and the military. This deadly gas It is odorless and colorless, and its inhalation causes chest tightness, nausea, nasal discharge, respiratory failure, spasms, convulsions and coma. As a result, the person loses control of his own body and dies from suffocation.

Widely known negative impact hydrocyanic acid and substances that contain it. Even a small dose can cause death.

Impact white powder, characterized by severe toxicity, is blocked by glucose. Contact with this gaseous substance is the cause of convulsive syndrome and respiratory failure.

Death occurs due to the binding of gas molecules to hemoglobin. Oxygen does not reach the internal organs, and the person simply suffocates.

Another type of poison is methyl alcohol. It is often confused with ethanol. Because of this, people who abuse counterfeit alcohol die due to intoxication. If rescue measures are taken on time, the likelihood of death will be significantly reduced. There is a high risk of complete loss of vision.

V-Ex is considered one of the most dangerous poisons. This gas is used as chemical weapons mass destruction. To penetrate the body, inhalation for a few minutes or short contact with the skin is sufficient.

A fast-acting remedy leads to death in just a quarter of an hour.

Don't forget about mercury and arsenic. The first slowly poisons the body, causing partial dysfunction of the central nervous system and subsequent mental disorder. All vital organs suffer from exposure to this metal. Vapors and soluble mercury compounds are formed already at room temperature, so you need to be careful when using a thermometer.

List of "Most strong poisons“It is impossible to imagine without arsenic. 33 element Periodic table Mendeleev has been used as a poison for centuries.

Symptoms of intoxication are similar to the clinical manifestations of cholera. It is possible to provoke chemical poisoning through potassium chloride. This substance is intended to fertilize the earth, but its penetration into the body is fraught with sudden cardiac arrest.

Plant substances


Some biological components are also dangerous; such poisons are presented in no less variety than synthetic ones. Call fatal outcome You can use chilibuja nuts. One of the most famous poisons, strychnine, is obtained from them.

Severe intoxication is accompanied by convulsions that lead to death. This substance is in small quantity used in the treatment of paralysis and to accelerate metabolic metabolism.

A dangerous poison called ricin is produced from castor beans. It is several times stronger than potassium cyanide, but due to technical difficulties it cannot be used as a weapon of mass destruction.

The outcome of poisoning directly depends on the method of penetration of the toxic substance into the body.

If inhaled, death is unlikely, but if even a few grains enter the bloodstream, there is practically no chance of a favorable outcome.

Among plant poisons, curare is considered the most famous. It was prepared based on herbs growing in the area South America. Death caused by this substance is very painful. The person gradually dies from paralysis of the respiratory system, remaining fully conscious but unable to move.

Poisons produced by representatives of the animal world


The world around us is full of dangers from which people are not immune. Often culinary preferences become the cause of his disability or even death. Fugu dishes are quite popular in Japan due to their “extreme” nature.

Due to the slightest mistake in the cooking process, the visitor can be poisoned. A similar reaction is explained by tetrodotoxin. It is found in organs puffer fish, skin and eggs of aquatic inhabitants living in the tropics.

Neurotoxins, particularly batrachotoxin, are present in the skin of amphibians from Colombia. Their body does not produce poison. It is formed as a result of dart frogs eating their normal food. The toxic substance “kills” the nervous system and causes respiratory failure.

To tropical fish and frogs you can add snakes and spiders. 250 species have been recorded in nature poisonous snakes. Unfortunately, there is no universal anti-snake serum. To administer the necessary antidote, you need to know what type of animal attacked.

Intoxication occurs when poison enters the bloodstream. A similar effect is caused by the penetration of chiriquitotoxin (chiriqui toad), alpha-latrotoxin (karakurt spider) into the body.

Pathogenic microflora


Poisoning can be caused by poisons produced by pathogenic microorganisms, including:

  • Bacteria Clostridium botulinum. They cause botulism, a toxic infectious disease that damages the central and peripheral parts of the nervous system.
  • Anthrax bacilli. There are two forms of development: intestinal and cutaneous. The first type of pathology leads to death in 95% of cases. With the second, 80% of patients survive.
  • Rods of the genus Clostridium. These are the causative agents of tetanus. Infection occurs when damp soil gets into an open wound. Characteristic symptoms include convulsive syndrome, respiratory and heart failure, and impaired swallowing reflex. In the absence of timely treatment, the likelihood of death is high.

The risk of intoxication of the body increases when consuming spoiled food. For example, if the storage conditions for potatoes are not met, solanine accumulates in them. Even bread can be poisonous if cereals infected with ergot were ground during the production of flour.

Poisonous mushrooms


The most common poisons are amatoxins.

They are part of fly agarics and pale toadstools. The first signs of poisoning may appear after 10-12 hours. Such slowness is fraught with serious complications.

First aid is too late, so prevent a negative impact on internal organs impossible. This will subsequently have a negative impact on general condition health.

10 fastest-acting toxic substances


There are several classifications of poisons. The defining characteristic is the minimum dose that can cause death.

The top ten included only natural substances:

  1. Diamphotoxin has the greatest toxic power. It is produced in the body of the larva of the leaf beetle of the genus Diamphidia. Its distribution range is in South Africa. The most dangerous poison can disrupt the electrolyte balance and greatly reduce the level of hemoglobin in the blood. The dose may not exceed 0.000025 mg/kg.
  2. The action of a cytotoxic poison called palytoxin becomes fatal at a dosage of 0.00015 mg/kg. It is formed as a result of vital activity coral polyps Palythoa toxica, P. Сaribacorum.
  3. Batrachotoxin is found in the skin of dart frogs of the genus Phyllobates. The lethal rate is 0.002 mg/kg.
  4. Typotoxin is produced by the Australian taipan. At least 0.002 mg/kg should enter the blood snake venom.
  5. Tetrodotoxin poisoning can occur from eating improperly prepared puffer fish. The critical dose is 0.008 mg/kg.
  6. Titutoxin is the venom of the yellow scorpion. A rapid lethal outcome is possible even when 0.009 mg/kg penetrates the body.
  7. Chiriquitotoxin is found in the skin of toads belonging to Atelopus chiriquiensis. The lethal dose is 0.01 mg/kg.
  8. Alpha-conotoxin is found in a substance secreted by the mollusk Conus geographus. The minimum sufficient amount is 0.012 mg/kg.
  9. Alpha-latrotoxin is produced by the Latrodectus spider (black widow). Death occurs from 0.045 mg/kg.
  10. Neurotoxin II is produced by the Central Asian cobra. The lethal dose is 0.085 mg/kg.

List hazardous substances does not end after listing these poisons.

Be careful, do not take unfamiliar drugs and do not touch animals if you are not sure of the safety of your plan. If poison gets inside, be sure to call ambulance. Delay costs lives.
