Physical and chemical properties of iodine. Different ways to use iodine

Medical 5% iodine solution

Iodine is a very popular remedy for disinfecting various skin lesions (abrasions, scratches, cuts, etc.). Another common use of it is the iodine grid, I’m sure many have experienced this in childhood. Do you know what iodine is made from? Why are some of its solutions brown and others purple?

Under normal conditions, iodine is black-gray crystals with a violet metallic luster. In medicine, we most often use a 5% solution of iodine in alcohol.

An alcohol solution of iodine is brown, a solution of iodine in non-polar organic solvents is violet, and iodine vapor is also violet.

How is iodine obtained?

Iodine is extremely rare in nature as a mineral; most often it is found in the form of iodides in sea water and in living organisms. Reserves of natural iodides are estimated at 15 million tons, 99% of reserves are located in Chile and Japan.

There are several ways to obtain iodine:


The raw material for the industrial production of iodine in Russia is oil drilling water, while in foreign countries that do not have oil fields, seaweed is used, as well as mother liquors of Chilean (sodium) nitrate, lye from potassium and saltpeter industries, which greatly increases the cost of producing iodine from such raw materials.

Application of iodine

One of the most important uses of iodine is in medicine. A 5% alcohol solution of iodine is used to disinfect the skin around various wounds.

If there are a large number of intramuscular injections, the patient is given an iodine mesh in their place. This is necessary so that the “bumps” formed at the sites of intramuscular injections dissolve faster.

Example of an iodine grid

Iodine-containing contrast agents are widely used in X-ray and tomographic studies.

If there is a deficiency of iodine in the body, its 5% alcohol solution should not be used internally!

In forensic science, iodine vapor is used to detect fingerprints on paper surfaces, such as banknotes.

Iodine is used as the positive electrode (oxidizer) component in lithium-iodine batteries for automobiles.

In halogen lamps, iodine is used as a component of the gas filler bulb to deposit the evaporated tungsten filament back onto it.
The dangers of iodine

Iodine is poisonous! The lethal dose of iodine is 3 g. It causes damage to the kidneys and cardiovascular system.

When inhaling iodine vapor, a headache, cough, runny nose appears, and possibly pulmonary edema.

Contact with the mucous membrane of the eyes causes lacrimation, eye pain and redness.

If ingested, general weakness, headache, fever, vomiting, diarrhea, brown coating on the tongue, heart pain and increased heart rate appear. After a day, blood appears in the urine. After 2 days, renal failure and myocarditis appear. Without treatment, death occurs.

Initially, iodine crystals are not divided into medical and technical - they receive this status during further processing.

Iodine– is included in the periodic table of Mendeleev and belongs to the group of halogens. It would be correct to call the element iodine from the Latin word Iodum. It consists of black-gray crystals with a violet metallic sheen (see photo). By the way, the ancient Greek name of the element is translated as “violet-like.” Iodine vapor has a pungent odor and purple color.

Iodine was obtained in 1811 by the chemist and industrialist Courtois from seaweed by heating in concentrated sulfuric acid. A few years later, the famous Gay-Lussac investigated the chemical properties of the element.

Iodine is very scattered in nature and due to this it is present almost anywhere on our planet. In free form in the form of minerals, this is a very rare substance; deposits are mainly developed in Japan and Chile. It is also obtained industrially from oil drilling waters, seaweed, and saltpeter.

The iodine molecule is chemically very active and is a strong oxidizing agent.

A large mass of iodine is contained in sea water - during geological processes, iodine was gradually washed away from the surface of the earth's crust under the influence of ice, snow, rain and carried away by rivers to the seas. A lot of it is found in chernozem soils and peat bogs. But mountainous areas, on the contrary, are very depleted in iodine, again due to the large amount of precipitation.

The action of iodine and its biological role

The action of a macronutrient is vital for a living organism. Iodine enters the human blood with food and almost the entire amount is absorbed in the small intestine, from where it penetrates the blood and the thyroid gland. It is also possible for a certain amount to enter with inhaled air and through the skin.

Iodine belongs to the biotic elements, i.e. to those affecting life activity:

  • The thyroid gland accelerates metabolism, iodine supplies the necessary organic compounds and hormones into the blood through reactions in the gland, which affect the level of metabolic intensity, oxidation processes and heat production.
  • Nervous system – thanks to the action of the element, the growth of healthy cells of the nervous system is enhanced, due to which excessive irritability disappears and the emotional background becomes stable.
  • Child development and growth - in the presence of iodine, protein synthesis occurs and metabolic processes in muscle tissue are accelerated, which leads to increased physical endurance, and it also has a positive effect on mental abilities.
  • Lipid metabolism - a macroelement that stimulates metabolism in the subcutaneous fat layer, and thus fights obesity and its unpleasant manifestation - cellulite.
  • Carbohydrate metabolism - through the work of the thyroid gland, iodine has an effect on the absorption of carbohydrates by the intestine.
  • Persistent immunity - consuming the element allows the body to actively resist colds and viral diseases.

Iodine also promotes the formation of phagocytes - cells in the blood that destroy harmful microorganisms. But the thyroid gland, in which it accumulates, is involved in all the actions of iodine. It is by passing through it that pathogenic organisms lose their strength.

Medicine associates the main biological significance of iodine as a macronutrient with endemic goiter, which occurs due to iodine deficiency. This disease occurs mainly in mountainous areas of all continents. It is promoted by a lack of cobalt and an excess of manganese, as well as an unbalanced diet, when there is an excess of carbohydrates and fats with a lack of proteins and vitamins. Treatment among the population will only make sense with an integrated approach. It is necessary to carry out prevention in combination with optimizing the composition of the environment and improving sanitary and hygienic living and working conditions.

Iodine in the history of medicine

Thousands of years before the scientific discovery of the element, people learned to use it correctly. Here are some facts from history:

  • already 5 thousand years ago in China, goiter was cured with the help of seaweed, and later recipes for treatment with extracts from the thyroid glands of animals (deer and pigs) were described;
  • Around the same time, the Sumerians were looking for a magical herb in the northern coastal regions, the description of which was lost, and later information appeared about the treatment of goiter with kelp or seaweed, and this was done at the state level;
  • about 3,000 years ago, the same Chinese discovered that the disease appeared more often in areas with mountainous terrain and poor drinking water quality, the Romans discovered this fact a thousand years later;
  • In Europe, the earliest artistic depiction of a goiter is dated 1215, while among the Indians it is dated to the third millennium BC. The paintings show a man with a goiter on his neck and a rattle called a "fool's scepter", which was an indication of dementia;
  • in the Renaissance, a goiter was considered an attribute of beauty, which may have been a consequence of that same dementia among the “fashion” setters;
  • The first mention of the term "thyroid gland" was used by the Englishman Thomas Warton in the mid-17th century, and the word "cretin" was used in 1754 in Diderot's Encyclopedia.

As you can see, the connection between goiter and a decrease in the level of mental abilities was discovered relatively recently. It was only in the mid-18th century that Denis Diderot described the word “cretin” as weak-minded, deaf, ugly and with a goiter up to the waist. And Napoleon drew attention to the fact that the presence of this disease in recruits initially makes them unfit for service. This theory was scientifically confirmed in 1896 by biochemist E. Bauman.

Daily value (need for an adult, for children, as well as for pregnant women)

The daily norm of a macronutrient depends on the body and age of the person. For example, for an adult the norm is about 150-300 mcg. School-age children need about 120 mcg per day, and preschool children need 50-90 mcg.

It is quite simple to determine the norm from the calculation that our body requires 2-4 mcg/1 kg of body weight. It is worth considering that not all iodine accumulates in organs and tissues; excess is excreted in urine and saliva. That is, the iron will take exactly the amount it needs. This is good only in the case of a healthy, functioning organ. If there are disturbances in the functioning of the thyroid gland, then a medical adjustment of the daily norm is necessary.

Pregnant women and women during breastfeeding, children and adolescents need an increased dose of the element. But it is imperative to obtain a recommendation from your attending physician.

It has been noted that in the post-Soviet space the situation is close to catastrophic. Because actual iodine consumption is about 50-80 mcg, which is three times less than required.

Interesting fact: depending on the changing seasons, the level of iodine concentration in the blood also changes. In autumn it begins to decline, and starting in March it rises until it reaches a maximum in June. The amplitude of the oscillations is insignificant, but has not yet been explained by science.

Lack (deficiency) of iodine in the body - what are the symptoms?

Lack of the macronutrient iodine, according to statistics, is widespread throughout the planet, and about a third of the entire population is at risk of iodine deficiency.

Iodine is found in the main thyroid hormones (about 60-65%), which, in turn, take part in metabolic processes and affect:

  • mental development;
  • bone tissue growth;
  • protein synthesis;
  • breakdown of cholesterol and fats;
  • stimulation of myelogenesis.

Iodine deficiency can lead to problems during pregnancy: congenital genetic abnormalities, stillbirth, cretinism. Therefore, it is necessary to monitor iodine levels throughout a person’s life. If it is deficient, the child may be born with increased body weight and jaundice, which leads to swelling and delayed healing of the umbilical remnant. The hairline is very weakened and is often affected by seborrhea. There may be a delay in the eruption of baby teeth, and subsequently permanent teeth. Deformation of the limbs occurs. When listening to the heart, functional murmurs are heard. Intestinal dysfunction occurs. Such babies may begin to sit and walk late.

Iodine deficiency can also lead to mental retardation at an older age; memory, motor skills, and perception suffer; they often suffer from colds, as a result of which it is difficult for them to concentrate and their academic performance declines. There may also be a violation of physical, sexual and neuropsychiatric development.

It is possible to achieve results in correcting iodine deficiency only by starting complex therapy from birth and continuing prevention throughout life. This is usually due to the fact that iodine is not able to accumulate in the body and comes exclusively from food. And its presence in the body is vital, so negligence is unacceptable.

For an infant, the source of the element is breast milk, but only if the mother takes the required amount. When artificial feeding, the dosage must be carefully maintained.

Chronic deficiency is obvious in the truest sense of the word. Externally, it is expressed in an enlargement of the thyroid gland (endemic gland). This disease is also called Graves' disease. Its essence lies in the fact that in case of iodine deficiency, iron increases in size to avoid insufficient production of hormones. Thyrotoxicosis develops (lack of those same hormones), the symptoms of which are increased heartbeat, nervousness, weight loss, sweating, restless sleep.

Also, the influence of an insufficient amount of the element affects the general condition of the body and a person’s appearance: weakness, drowsiness, hearing and memory impairment, pale and dry skin, hair problems, shortness of breath.

A folk remedy for checking iodine deficiency is applying a grid with an alcohol solution to the skin. If it quickly disappears, then measures need to be taken, but if the drawing does not disappear within 24 hours, then everything is in order with the presence of the element, although you should not stop there and continue prevention. But doctors do not trust this method and use urine or blood tests. They believe that when applied to the skin, iodine can only have an irritating effect, causing blood outflow and dilation of skin capillaries.

Today, iodine deficiency is the most common disease spread by non-infectious means, which leads to mental retardation of the entire nation. This disease is becoming an “epidemic” and control in particularly affected countries must take place at the legislative level.

According to WHO statistics, about 200 million people are considered affected and almost a billion are at risk.

Signs of excess iodine and iodine poisoning

Excess iodine in the body can still exist, despite a global deficiency of the element as a whole. It may be caused by a violation of iodine metabolism and its excessive intake. An excess of this chemical can cause poisoning, because high concentrations have a toxic effect. Employees of enterprises with increased harmfulness are exposed to such poisoning, where iodine is released in the form of steam.

The toxic effect of the element can lead to disruption of the general condition of the body (muscle weakness, sweating, diarrhea and weight loss), and with chronic action, painful sensations in the stomach, vomiting, lacrimation, tinnitus, and dizziness may appear. Depigmentation of the skin and hair occurs, which causes premature graying.

What food sources does it contain?

Iodine consumption occurs mainly in foods of plant and animal origin. But it is worth considering that the content of the element is determined by the condition of the soil on which they are grown. The most saturated areas are located in areas close to the seas or oceans, and the poorest are in mountainous areas due to leaching from the soil by precipitation. And it has been noticed that city residents suffer less from shortages than rural residents. The reason for this is the consumption by city residents of a wide range of imported products.

In addition to iodine-rich seafood (seaweed, fish, shrimp, etc.), you should eat radishes, carrots, tomatoes, potatoes, cabbage, currants, strawberries, eggs, and onions. The element is also found in milk, beans, meat and buckwheat.

But consuming soy products doubles the need for macronutrients, because they (the products) cause an increase in the volume of the thyroid gland.

High-quality seafood is very expensive, so to replenish the iodine balance in the body, you have to limit yourself to consuming sea salt. But at the same time, many do not take into account the fact that during the heat treatment of this product, the previously indicated chemical element practically does not remain in it. When using a special salt saturated with iodine, the value is short-lived, for the reason that the element “evaporates” from an open pack due to the volatile properties of this substance. Although such salt in our conditions is the most effective and cheapest remedy. However, it is necessary to add it to food only before consumption, and not during the cooking process.

An alcohol solution of iodine cannot be used to replenish iodine deficiency, because it is suitable for external use only and contains high concentrations that can cause poisoning with this substance.

Medical preparations of iodine are produced in the form of sodium and potassium salts, Lugol's solution, infusions and vitamin preparations. However, they may cause some allergic reactions.

Indications for use

The indications for prescribing a macronutrient are quite extensive, but all are related to the stable functioning of the thyroid gland:

What is the role of iodine for our body? Many of us are accustomed to seeing this drug as an antiseptic of the pharmaceutical industry. In fact, it belongs to a group of useful microelements that are responsible for a huge number of functions in our body.

A low level of this substance leads to hormonal imbalance. This affects the emotional and physical state of a person.

Composition and indications for use

The composition of the drug consists of potassium iodide and ethanol. These components are a solid molecular lattice. The liquid has a purple tint and a pungent odor. When applied externally, it has an antiseptic effect, as a result of which up to 95% of pathogenic microflora is destroyed.

The use of iodine internally has a positive effect on the functioning of the thyroid gland. The composition helps enhance dissimilation processes, stimulates the production of the terrotoxin hormone, and also triggers tissue metabolism processes.

An incorrectly selected dosage can provoke excessive accumulation of radioactive substances in the tissues of the thyroid gland. Here, impaired production of vital hormones is noted. This entails the development of pathological processes that can cause ovarian or pituitary dysfunction.

WHAT IS IODINE USEFUL FOR THE HUMAN BODY?

The drug is intended for patients with the following symptoms:

  • infectious - inflammatory processes on the mucous membranes;
  • neuralgia;
  • myositis;
  • syphilis;
  • atherosclerosis of the vascular system;
  • excess cholesterol;
  • laryngitis;
  • intoxication of the body with heavy metals;
  • ozena;
  • disease of the cardiac system.

IMPORTANT: “Before starting therapeutic treatment, it is recommended to seek help from a medical doctor. The specialist will select the optimal dosage based on clinical indications and medical tests. An incorrectly selected dose can provoke the emergence of new pathological foci in the body.”

How is iodine mined and obtained?

Where do microelements iodine come from? Today, several methods are known for producing potassium iodide on an industrial scale. Each of them differs in its technology and the resulting volume.

HOW IS IODINE OBTAINED? There are several methods for extracting useful microelements. These include:

Processing of natural raw materials. Sea kelp is used here. It has been scientifically proven that 1 ton of dried seaweed contains up to 6 kg of iodine, while sea water is saturated with only 50 mg. Until the end of the 70s of the 19th century, this method of obtaining a natural trace element was considered one of the best;

Obtaining iodine from nitrate waste. They contain up to 0.5% iodized minerals and potassium iodide. This method of obtaining microelements began to be used in mid-1867. The main advantage of this method was its minimal cost. As a result of this, it has gained wide popularity among manufacturers all over the world;

Extraction from natural solutions. To do this, use salty sea water or liquid from oil settling tanks. These solutions contain up to 50 mg/l of iodide. Up to 100 mg/l of liquid is fixed in oil solutions;

Ionite iodination. This extraction method is based on chemical reactions, which result in selective absorption of iodinated molecules.

Contraindications and side effects

There are a number of medical contraindications to the use of this drug. For example, dry iodine often causes individual intolerance to one of the components of the composition. As a result, a person experiences a severe allergic reaction in the form of redness and rashes.

People with the following diseases are prohibited from consuming iodine in water. These include:

  • duodenal ulcer;
  • diabetes mellitus;
  • nephrosis;
  • tuberculosis of the kidneys and lungs;
  • furunculosis;
  • diathesis of hemorrhagic environment;
  • hives;
  • acne;
  • acne.

Improper use of radioactive iodine solution can cause adverse reactions in the body. These include:

  • Quincke's edema;
  • lacrimation;
  • local application is accompanied by redness of the skin;
  • hives;
  • heavy salivation;
  • increased sweating;
  • tachycardia;
  • diarrhea;
  • increased nervousness.

If such symptoms are detected, it is necessary to seek appropriate help as soon as possible.

Where is the chemical element found?

In the periodic table, iodine is number 53. Under normal conditions, this chemical type of non-metal appears as dark purple crystals that have a pungent and specific odor. This substance belongs to the group of active collagens.

Today you can get your daily dose of the substance from food. In some of them, the iodine content can reach the maximum permissible level. Excessive content of this microelement affects the psycho-emotional state of a person. He becomes too irritable or, conversely, passive.

Foods high in iodide include:

  • fish;
  • sea ​​shellfish;
  • crabs;
  • squid;
  • kelp;
  • green apples;
  • sea ​​herring;
  • hard cheese;
  • dairy products;
  • mushrooms.

Products that do not contain iodine include:

  • sugar;
  • canned goods;
  • fruit jelly;
  • paste.

It is difficult to overestimate the influence of microelements on the condition of the human body.

The main biological role of iodine is participation in the processes of synthesis of thyroxine and triiodothyronine - thyroid hormones of the thyroid gland. The optimal amount of these substances has a direct impact on many processes occurring in the human body.

Only 150-200 mcg of iodine per day is required to maintain health. Although iodine, which belongs to the group of halogens, was discovered a little more than two centuries ago (in 1811), eastern healers used this substance to heal wounds 1000 years before the birth of Christ. It was extracted from seaweed.

What are the benefits of iodine for the body?

Iodine is responsible for the normal functioning of the hormonal system, in particular the thyroid gland, and the production of the hormone thyroxine. This organ produces specific cells - phagocytes, the main task of which is to detect and neutralize damaged cells and pathogens.

Iodine takes part in the processes of protein synthesis and the formation of cartilage tissue, as well as in the functioning of the brain. The optimal concentration of the microelement in the body ensures the functioning of the nervous system and is responsible for mental health. Thanks to the intake of the recommended daily intake of iodine, increased irritability is eliminated and performance increases.

The microelement is indispensable for maintaining the beauty of the skin and skin appendages (nail plates, hair), as well as bone tissue and teeth. The intake of optimal microdoses of iodine with food or dietary supplements helps to activate all types of metabolism, enhance the processes of burning subcutaneous fat and dissolve the unaesthetic cellulite crust, since this substance is directly involved in the process of lipid metabolism.


Signs of iodine deficiency in the body:

  • dry skin, brittle hair and nails, separation of the nail plate and ends of strands;
  • excessive fatigue, apathy, drowsiness, bouts of blues, aggression and irritability;
  • decreased ability to remember and assimilate received information;
  • causeless increase in body weight while maintaining the usual diet;
  • hoarseness of voice;
  • swelling of tissues;
  • chills;
  • arrhythmia, blood pressure surges;
  • constipation;
  • increased blood cholesterol levels.

If thyroid function decreases and there is a lack of iodine, an endocrinologist diagnoses hypothyroidism and prescribes appropriate treatment. Traditional methods for determining the presence of iodine in the body include applying an iodine grid: if the stripes disappear throughout the day, it means there is a deficiency of this microelement.

In rare cases, there is an excess of iodine in the body, as a result of which the thyroid gland begins to synthesize an excessive amount of hormones, and hyperthyroidism and thyrotoxicosis develop. This condition can cause excess daily doses of iodine supplied from outside or metabolic disorders. Only an endocrinologist can accurately determine the condition of the thyroid gland after conducting appropriate laboratory tests.

What foods contain iodine

  1. From time immemorial, seafood has been recognized as the leader in iodine content: sea salt, seaweed (kelp, bladderwrack), scallops, brine, mussels, shrimp, lobsters, oysters, squid, crabs, etc. There is a trace element in sea fish. Just two tablespoons of seaweed or 0.15 kg of hake, haddock, and pink salmon provide the body with a daily portion of a valuable compound.
  2. The iodine content in various fruits and leafy greens directly depends on the amount of this trace element in the soil. List of vegetable crops in which the highest concentration of iodine is observed: tomatoes, carrots, beets, potatoes, radishes, garlic (especially green arrows), bell peppers, eggplant, turnips, spinach, onions, blue onions, lettuce, asparagus, legumes It should be noted that eating white cabbage and radish leads to leaching of iodine from the body.
  3. Iodine-containing fruits: feijoa, citrus fruits, pineapple, banana, black grapes, including dried ones, melon, persimmon, prunes, currants, dates. Iodine is also found in mushrooms, especially in champignons, Polish and white, honey mushrooms, russula, boletus and other cap mushrooms, as well as in truffles.
  4. Other products containing iodine: walnuts, water, milk, cereals, especially millet and buckwheat, bread, meat (turkey, beef, veal, pork), hard cheese, butter.

What are the benefits of iodine for skin, hair and nails?

Dry, thinning, flaking at the ends and damaged hair is one of the signs of iodine deficiency in the body. Before spending money on expensive cosmetic procedures to restore your hair, get examined by an endocrinologist to determine the level of microelements in the blood (an analysis is carried out for the content of thyroid hormones).

Sometimes, to normalize the condition of curls, nails and eliminate dry skin, it is enough to adjust the diet, enriching it with seafood and other products with active compounds, or to include dietary supplements with iodine in the menu, for example, fucus vesicularis capsules or dry kelp powder.

Using local hand baths with the addition of sea salt and a few drops of alcohol tincture of iodine can significantly strengthen the nail plates. And the so-called iodine network will significantly reduce the period of recovery of edematous tissues after bruises and inflammation.

How to properly use iodine as a disinfectant

One of the most famous effective antiseptics, actively used for more than 100 years, is a five percent alcohol solution of iodine. It is hardly possible to meet a person who has never used iodine in his life, along with a solution of brilliant green and hydrogen peroxide. It is regularly smeared on the knees and elbows for children's microtraumas, and is also used as part of “sea water” for gargling for inflammation and sore throat (salt and a few drops of iodine are dissolved in a glass of warm water).

The product has disinfecting, antimicrobial, antifungal, wound-healing, anti-inflammatory, anti-edematous properties and is widely used for the sanitation of wounds and other skin damage. A bottle of iodine, as a rule, is present in any first aid kit and is a means of quick treatment both at home and in the hospital.

For minor skin lesions, treatment with iodine tincture is carried out using a cotton swab generously dipped in liquid. The procedure prevents the development of inflammation, accelerates epithelization processes (healing) and destroys pathogenic microflora, preventing infection from entering the wound. The use of iodine as a local antiseptic is recommended for children from the age of three.

Open bleeding wounds should be treated with hydrogen peroxide or chlorhexine. In this case, iodine is applied only along the outer edge of the wound to prevent infection. Internal tissues cannot be treated with iodine tincture before epithelialization begins, since the product can cause a burn, which will significantly slow down healing.

How to treat toenail fungus with iodine

Onychomycosis or fungal infection of the nail plate is quite common. Iodine tincture is an effective, time-tested and cheap remedy for eliminating the problem. As practice shows, this remedy allows you to completely restore the nail and destroy the fungus, but only at the initial stage of the disease.

First, the nail plate is trimmed as much as possible and filed along the edges and top with a nail file. Every evening you should steam your feet or hands in a bath with laundry soap and soda, wipe them dry, and then pour alcohol tincture on the affected nail.

If there is no result within a month, you should visit a dermatologist as soon as possible, who will prescribe appropriate treatment with modern pharmaceutical drugs (ointments, varnishes, gels, sprays, drops, tablets).

To prevent infection from entering the body, do not forget to treat your nails and adjacent skin with an iodine solution after a pedicure, manicure, cuticle removal or mechanical damage to the periungual fold (it is most convenient to do this with a cotton swab).

Treatment with iodine for the thyroid gland

Iodine is not synthesized in our body, but only comes from food, dietary supplements or medicines. When diagnosed with hypothyroidism, the endocrinologist prescribes appropriate iodine-containing pharmaceutical forms, the use of which is permissible only under the supervision of a doctor. At the same time, the nutritionist adjusts the diet, strengthening it with iodine-containing products.

To treat thyroid nodules, use the following recipe: grind buckwheat in a coffee grinder, crush walnut kernels, mix with natural honey (1:1:1). In this composition, nuts are a natural source of iodine. Take a tablespoon of the mixture three times a day with a glass of water. The course of treatment is 30 days, repeated after a three-month break.

What is radioactive iodine?

Isotope I-131 or radioactive iodine is a form of trace element used to treat thyroid diseases. Therapy is carried out only under the supervision of a specialist. The decision on the need for such treatment is made by the doctor after a complete examination of the patient.

Treatment with radioactive iodine

Radioactive iodine is used to remove nodules on the thyroid gland. This therapy destroys the tumor in the organ, preventing the formation of metastases in oncology. In a hospital setting, the patient takes the isotope I-131 (radioactive iodine) in the form of gelatin capsules (orally) or an aqueous solution. Accumulating in the cells of the thyroid gland, the substance exposes the entire organ or thyroid remnant to radiation (gamma and beta) (if the thyroid gland was previously removed).

The use of iodine in the garden

A five percent alcohol solution of iodine is a very valuable composition for summer residents. And the point is not only in its ability to effectively disinfect minor abrasions, cuts, scratches and other damage to the skin, but also in its undoubted benefits for many cultivated plants. Experienced gardeners with the help of iodine successfully solve problems that arise during the growing season, using, although cheap, but undoubtedly a powerful and natural remedy.

Iodine for strawberries and strawberries

Spraying strawberry bushes and garden strawberries with an iodine solution (8-10 drops per standard bucket of water) protects the plantings from gray rot, a fungal disease that causes serious damage to berry plants. The procedure is carried out three times, starting from May and until the flowering period, with an interval of 10 days. In addition to combating diseases, this event activates growth processes, increases plant immunity and fruiting.

Iodine for tomatoes

To increase the resistance of tomato seedlings against late blight, a few weeks before planting, water them at the root with water with the addition of iodine (1 drop per 3 liters of water). Watering tomato bushes after moving them to a permanent place (a garden bed or a greenhouse) with an iodine solution (3 drops per bucket of water) at the rate of 1 liter per plant is an excellent feeding. Iodine, absorbed by tomatoes from the soil, increases the number of ovaries and the size of future fruits.

To combat late blight - the main enemy of tomato plantings - use the following remedy: add a liter of whole milk and 15 drops of iodine tincture to a bucket of water. Abundant irrigation of tomato bushes is carried out every two weeks, starting from the moment of transplantation to a permanent place. This composition allows you to prevent the development of fungal disease or minimize its manifestations.

Iodine for cucumbers

Iodine is also effective against downy mildew in cucumber plantings. The prepared solution (1 liter of skim milk is poured into a bucket of water and 11-13 drops of iodine tincture are added) is sprayed on the leaves of the cucumber plant when the first signs of the disease appear. The procedure is repeated after 10 days.

This unique product can be purchased for pennies at any pharmacy. Adopt recipes for using iodine and you can make your life much easier!

When we hear the word “iodine”, we immediately imagine a medicine that is used to disinfect a wound and treat inflammation. With iodine you can quickly relieve bruises and bruises on the skin. But, above all, it is a chemical element whose properties make it a truly universal remedy. It is everywhere around us, although in small quantities: in soil and minerals, in plants and water. It is practically insoluble in water and can evaporate at normal temperatures.

What is iodine

Iodine is an element that is responsible for the normal growth of all mammals, including humans. If it did not exist in nature, life would look different; It’s even hard to imagine what people would be like.

Iodine enters the human body through water and food, and through inhaled air and through the skin - in small doses; then accumulates in the thyroid gland. Participates in the synthesis of thyroxine and triiodothyronine - hormones necessary for the normal functioning of the thyroid gland. When the thyroid gland is functioning normally, its cells extract iodine from the blood. At the same time, metabolism proceeds normally, which means that iodine affects the functioning of the entire body.

It also helps the formation of cells necessary for our body, a kind of cleaners that capture and destroy foreign microorganisms and damaged cells. This element is of paramount importance for the normal growth and development of children and adolescents; participates in the formation of bones and cartilage, in protein synthesis, stimulates mental abilities, improves performance and neutralizes fatigue.

Iodine is also necessary for lipid metabolism and metabolism in subcutaneous tissue. It promotes the breakdown of fat and prevents the appearance of cellulite. A normal amount of iodine in the body helps burn fat during diets, keeps you active and gives you energy, and promotes healthy skin, nails and teeth.

How does iodine deficiency manifest itself and the consequences of its deficiency?

Iodine deficiency and deficiency develops in residents of areas where the soil and water are poor in this element. The deficiency condition is aggravated if the food of these people is poor in complete proteins and vitamins C and A. Then, “Hashimoto’s goiter” develops - a disease of the thyroid gland; immunity weakens and metabolic processes in the body are disrupted; memory deteriorates, the affected person’s energy is quickly depleted and fatigue is constantly felt; he is irritable, often has a headache, his weight changes sharply, he experiences severe sweating and drowsiness. Iodine deficiency diseases are the basis of cardiovascular diseases and respiratory disorders.

Thyroxine and the thyroid gland

- iodinated thyroid hormone. It is an inactive compound representing 90% of the gland's production. It is capable of being converted into the active phase and converted under the action of enzymes into triiodothyronine. Two iodine-containing hormones optimize energy processes in the body, affect the nervous system and the functions of the heart, kidneys and liver.

Thyroxine affects blood pressure - increases it; mobility and mental activity depend on the level of the same hormone. Thyroxine affects metabolism and the speed of thought processes. This affects your heart rate.

With normal levels of the hormone in the blood, there is no excess weight, unless there are diseases that contribute to excess weight. This type of effect is associated with the role of thyroxine in metabolic rate. When a person with normal thyroxine levels eats more than necessary, the body produces more thyroxine and active fat burning follows.

Scientists have found that an iodine solution, when in contact with the urine of a pregnant woman, gives an oxidation reaction. This happens due to the fact that iodine meets with female hormones, which are produced by the body only during gestation. Under the influence of this oxidation reaction, the iodine solution changes its usual brown color to purple.

An interesting fact is that in translation from ancient Greek the word “iodine” is translated as “purple”. It was named so because since ancient times, this substance has been used to check the freshness of certain products, as well as their starch content.

How to take a pregnancy test using iodine
