Content

The antiseptic properties of this substance have been known since the 19th century. The solution was used as a disinfectant for a long time everywhere until contraindications appear for certain categories of patients. Boric acid is placed in the ear as an effective remedy for. It has an antibacterial effect, eliminates inflammatory processes, and has a warming property. Boric acid solution for ears correct use allows you to quickly cure the patient.

Is it possible to drip boric acid into the ear?

Why boric acid is needed: it creates an unfavorable environment for fungi and bacteria, disinfects the skin and mucous membranes. It is used in the treatment of dermatitis, ear inflammation,. When using a boric acid solution for the ears, it is important to take into account the nuance. This compound quickly enters the blood through the skin and is accumulated by the body. Its concentration in tissues gradually increases. It takes a long time for the substance to leave the body.

Boric acid in the ear of children is recommended in modern pediatric practice, but only after being prescribed by an otolaryngologist. Studies have shown that even washing the ears from the outside is dangerous for the child; the dosage must be carefully adjusted. Boric acid in the ear during pregnancy is contraindicated; it can affect the development of fetal tissue.

In medical practice, after performing surgery on the middle ear, surgeons blow a powder form of the medicine into the ear canal. For patients over 15 years of age, the diluted drug is prescribed in the absence of damage to the eardrum. For otitis media, a 3% alcohol composition is prescribed. The course of instillation should not last longer than a week. The product should not be used internally; if you accidentally drink it, you can get poisoned.

Instructions for use of boric acid in the ear

Before treating ears with boric acid, in addition to the medicine itself, you also need to prepare hydrogen peroxide. A 3% peroxide solution will prepare for the procedure and cleanse the ear canals of dirt. Using a pipette, take 5 drops of the solution, drop it into the ear canal, wait 10 minutes, change the position of the head, wipe with a dry cotton pad. Then instill the prepared medicinal composition.

How to dilute boric acid in powder

Boric acid for ears is available in the form of a white powder or alcohol solution. It’s easy to dilute the powder from the bag: take boiled water, the temperature of which should not exceed 40 degrees. The proportions are:

to obtain a 2% solution, 5 g of powder per glass of water is required;
so that the output is 3% composition - take 6 g of the substance per glass;
A 10% concentration is obtained by diluting 100 g of powder with one liter of water.

How to drip

Before instillation, the medicine is warmed to body temperature. The patient lies on his side, with the diseased organ facing up. 3-4 drops of the composition are injected into the ear canal using a pipette (alcohol 3% is more often used). You cannot move immediately after the procedure, the liquid will not be distributed evenly. You need to lie down, maintaining the original position, for 10 minutes. Wipe off any remaining medication with a cotton swab. When, it is instilled 3 to 5 times per day.

Boric acid in the ear will warm the ear canal; a feeling of warmth or a slight burning sensation after instillation is normal. If a drug is prescribed to children, it is in combination, with drops based on antibiotics. If pus leaks from the ear canal, such therapy is contraindicated. How the procedure is performed for a child:

wash the ears with hydrogen peroxide;
instill 1-3 drops of the solution, leave the baby lying on his side for 10 minutes, plug the ear canal with a cotton swab for 5-10 minutes;
an hour later, antibacterial compounds are dripped.

How to make a compress on the ear

The product is also successfully used in the form of tampons soaked in the solution.

Turunda is impregnated with the drug and placed not very deeply, so as not to injure the eardrum. Keep the compress for up to 3 hours, the course of treatment is 5-6 days.

Video about ear treatment with boric acid

Treating ear diseases with this medicine is no longer as common as it was in the 80s or 90s of the last century, but this method is still common today. Theoretically, doctors warn about the dangers of the drug and its toxicity. In practice, ENT doctors recognize the method as effective and make prescriptions. Know about possible consequences therapy, it is important to carefully select the dosage and carefully carry out the procedures. Some practical advice You will learn about using the product at home from the video instructions.

Proper preparation of the working composition for processing tomato bushes is very important to obtain the desired result.

There are a large number of tomato fertilizing using boric acid and, accordingly, many various options preparing an aqueous solution of the drug.

Boric acid is widely used by gardeners when growing tomatoes.

It can be used in caring for them in many ways: to eliminate boron deficiency and provide adequate nutrition, for ovaries, accelerating ripening and improving the taste of fruits, as well as in the fight against pests and diseases of the crop.

Only a properly prepared boric acid solution has beneficial properties for tomatoes.

For this required quantity The powder is dissolved in hot water, for example, 1 liter, after which the liquid is brought to the required volume.

Depending on the purposes and processing methods, an aqueous solution of boric acid is prepared in certain optimal proportions. Don't know how to dilute boron? Now we will tell you how to prepare the composition for various purposes.

Which recipe to use - choose based on your situation.

Watering solution

What solution can you water plants with?

To do this, prepare an aqueous solution of boric acid by adding 1 gram of powder per 1 liter of water (or 10 grams of the drug per bucket of water). The working fluid is poured into a spray bottle with small holes and the treatment is carried out.

This composition can also be sprayed on flower brushes before opening flowers and crops - this treatment helps to increase fruit set.

During the fruiting period, if desired, additional spraying is carried out with a solution prepared according to the above proportions, spraying it onto the fruits in order to improve the taste characteristics of the crop.

Note! Exceeding the concentration of boric acid solution when spraying can provoke.

Disease Control Ingredients

on tomatoes and stops its development.

This dangerous disease tomatoes can be cured by spraying the entire green part of the tomato bushes.

To prepare this, you need to dilute 10 grams of boric acid in a bucket of water. To increase effectiveness, it is recommended to add 30 drops of iodine tincture.

When carrying out treatment, it is important to apply the solution evenly over the entire aboveground part tomatoes - leaf blades, flower clusters, stems, fruits. The solution should not be allowed to drain from these surfaces.

The effect of spraying with boric acid against late blight will not take long to appear - already 2-3 days after it, results are noticeable.

There is another recipe for a solution that is effective in combating late blight of tomatoes, the main component of which is boric acid. To prepare it, take 5 grams of the drug, 1 liter of milk (it can be replaced with whey) and 20 drops of iodine in a bucket of water.

For pest control

Boric acid also finds its use in controlling tomato pests. It can be used against aphids and ants, which carry it from bush to bush.

The main disadvantage of the drug in this case is its slow action, so you will have to wait quite a long time for the desired result - within a week.

Methods of using boric acid against pests can be different: preparing baits, scattering dry powder or preparing an aqueous solution.

An aqueous solution against ants is prepared by diluting a package (10 grams) of boric acid in a bucket cold water. The working fluid is poured onto anthills and soil between the rows.

You can fight aphids by spraying the bushes with a solution prepared by dissolving 2 grams of boric acid in 1 liter hot water. The resulting liquid is cooled and applied to the green part of the bush.

In order to eliminate aphids and ants refers to traditional methods: active substance safe for humans, inexpensive, accessible and easy to use. However, its effectiveness compared to chemical agents is much lower, therefore boric acid Most often used to prevent these pests or at the first signs of their appearance.

Preparing liquid for soaking seeds

Soaking tomato seeds in a solution of boric acid increases their germination and is also preventive treatment boron deficiency in the future.

To prepare the working fluid, you need to dilute 0.2 g of powder in 1 liter of water. The seed material is immersed in the prepared composition for 24 hours, then washed plain water and dry.

Dosage for soil pre-treatment

Preliminary watering of the soil with an aqueous solution of boric acid is carried out when its composition is poor (on uncultivated soils).

They also perform it with precise knowledge of the boron deficiency in it. The soils that are poorest in this microelement are:

limed
sod-podzolic,
swampy.

Before planting seedlings, the soil is spilled with a solution of boric acid (0.2 g of powder is dissolved in 1 liter of water), using 1 bucket of the composition per 10 m2. After applying fertilizer, the rows are loosened.

Rules for preparation and use

The advantage of using boric acid is the unlimited shelf life of its prepared aqueous solution. The dissolved powder does not change its properties during storage, so the working fluid is suitable for repeated use.

The range of uses of boric acid when growing tomatoes is very wide, so this product is indispensable in caring for the crop.

Useful video

By watching the following video you can see for yourself how the boron solution is prepared. Perhaps this will also help you avoid mistakes.

For normal plant development a number of useful substances and microelements. One of the most important is boron. It promotes the process of synthesis of nitrogenous components and has a positive effect on metabolism, increasing the amount of chlorophyll in the foliage. Experts believe that boric acid is one of the most accessible and simple compounds of this microelement. It is successfully used in complex fertilizers.

The active use of boric acid in the garden has many beneficial effects.

What is this product? These are colorless, odorless crystals that quickly dissolve in an aqueous environment.

Useful qualities

This product can be used on a variety of soils. Gray and brown forest and soddy-podzolic soils give good results after application. Gardeners also recommend applying this substance to light soils, to black soil. It is mandatory to use boric acid for gardening on acidic, waterlogged or dark-colored soils.

This product perfectly helps to increase the number of ovaries and significantly increases productivity. After using boric acid for a vegetable garden or garden, it actively develops root system and the stem of the plant. The amount of sugar increases and improves taste qualities fruits

Boron is a “fixed” element in plants. It cannot change from old withering leaves to young ones. Therefore, it is necessary for plants throughout the growing season.

Experts know that everything horticultural crops V different quantities need boron. We will conditionally divide all of them into 3 groups of needs:

small (strawberries, potatoes, legumes);
medium (tomatoes, carrots, stone fruits);
high ( fruit trees, beets, cabbage, rutabaga).

Although potatoes and strawberries are classified as having a low requirement for this microelement, its deficiency can negatively affect these crops.

Signs of boron deficiency in plants

Not only do boron need additional nutrition acidic soils, but also soils with high humidity. The lack of this substance affects plants in different ways. Corn and potatoes require virtually no additional application. But if this microelement is not enough, then the potato leaves begin to turn yellow, the tubers do not develop, and cracks appear on their surface.

A lack of boron in plants can also lead to the development of diseases - brown and dry rot, baketriosis, and blight. The following signs indicate a lack of this microelement in the soil:

the buds dry out;
plant stems become crooked;
growing points die off;
plant leaves become curly and pale;
no flowering.

These signs are especially pronounced during dry seasons. Many amateur gardeners, when harvesting a small harvest, blame it on the lack of moisture, and not on the lack of essential microelements in the soil.

Methods of use in the garden and in the garden

The benefits of boric acid are invaluable and quite varied. But you should be careful with this element, because an excess can harm the plant, accumulating in the fruits, like other fertilizers. Therefore, before you get a positive effect from using boric acid for your garden or vegetable garden, you should pay attention to the advice of experienced gardeners. The main task is to comply with the dosage and use the drug correctly.

Consider these methods of using boric acid:

stimulation of seed germination;
preparing the soil for planting;
foliar planting;
root feeding.

Boric acid is actively used to stimulate seed germination. How to dilute this product correctly? It is necessary to take 0.2 g of powdered product per 1 liter of water. The crystals dissolve quickly. Seeds are soaked in this solution:

onions, carrots, beets - for 24 hours;
cucumbers, cabbage, zucchini - for 12 hours.

How to dilute boric acid for sowing or planting? Everything is the same: in proportion to 1 liter of water - 0.2 g of product. Planting beds should be watered with this solution. Consumption: 10 l per 10 m 2. Then the soil should be loosened and then the seeds should be planted. This method is used if there is a suspicion of a deficiency of this microelement in the soil.

Boric acid is very important. Solution concentration: per 1 liter of water - 0.1 g of boric acid. The first spraying is carried out at the stage of bud formation, the second - at the flowering stage, the third - at the fruiting stage. Sometimes other drugs with boric acid are used together. For spraying in this case, take a smaller dose (5-6 g per 10 liters of water).

Foliar fertilizing with boric acid must be carried out in cloudy weather. Experienced gardeners always postpone this procedure until the evening to avoid sunburn. If it is necessary to spray on hot days, you should first water the plant.

Fertilizing with boric acid at the root is rarely used. In this case, you should make sure that the soil really lacks this element. Most often this procedure is used for seedlings flower plants, which grow on a mixture of peat and sand or soddy-podzolic soils. The solution is prepared using 0.1-0.2 g of the drug per 1 liter of water. But first, water the plant generously with plain water to avoid chemical burns.

Remember that boric acid dissolves well in hot water. First of all, you need to dissolve 1 sachet of the drug in 1 liter of hot water. After this, you should bring the solution to the required volume by mixing with water room temperature.

Potato processing

The following factors indicate a lack of boron in potatoes:

general developmental delay;
fungal scab disease;
the growth point is inhibited;
leaves turn yellow;
The petioles turn red and become brittle.

Potatoes' need for boron directly depends on the soil, or more precisely, its acidity. This indicator is also affected by temperature and the ratio minerals contained in the soil. If an amateur summer resident exceeds the norm when applying nitrogen and potassium, then the plant’s need for boron increases significantly. If the dose of phosphorus fertilizer was increased, the need decreases.

If the first signs of scab damage appear on potatoes, it is necessary to use boric acid at a rate of 6 g per 10 liters of water. To prevent this disease, it is necessary to spray potato tubers at the stage of appearance of the first shoots.

Beet processing

Lack of boron in beets provokes the occurrence of wormhole and core rot. Often the cause of such lesions is fungal disease- fomoz. In this case, concentric light brown spots appear on the leaves, in the center of which there are black dots. Afterwards the disease spreads to the root crop. On initial stage When cut, the tissues of the root crop are dark brown in color. Subsequently, the affected parts dry out and become rotten.

Before planting, the seeds should be soaked in a boric acid solution. It is also necessary to add it to the soil to prevent the appearance and development of Phoma.

If the soil and seeds are properly prepared, to obtain good harvest It is enough to spray the beets once with boric acid at the stage of 4 leaves. As practice shows, the result will be excellent.

Tomato processing

Lack of boron in tomatoes also causes various diseases. Young leaves and branches begin to grow only from below, the base turns black and becomes brittle. In other words, the tomato turns into a bush. Brown spots appear on the fruits, the flesh becomes dry. Some summer residents use a solution of boric acid against late blight.

For prevention, seeds must be soaked in solution before planting. Before planting, this solution is also added to the soil. Care should be taken to carry out foliar feeding before flowering. Boric acid has a positive effect on tomato ovaries.

To speed up ripening and accumulation of sugar, you can re-spray with boric acid at the green fruit stage.

Processing cucumbers

Boric acid is also actively used for cucumbers. This element helps the plant in the process of flowering and ovary.

To improve the ovary and prevent rotting of zucchini and zucchini, a solution is also used: 2 g of the product per 10 liters of water. The plants are sprayed with it.

Use the same boric acid solution for peppers and eggplants.

Processing pears and apple trees

Signs of boron deficiency in pear and apple trees:

thickening of leaves;
darkening and suberization of veins;
leaves warp and fall;
small leaves at the ends of the shoots are collected in the form of a rosette;
the top of the tree dies.

These signs contribute quick drying flowers, deformation of fruits, on which traces of affected tissues appear.

Light spots appear in the apple pulp, which gradually turn brown and turn into a sponge.

Foliar feeding (10-20 g per 10 liters of water) will help restore boron deficiency. Spray the entire crown evenly. The first time - during the opening of the buds, the second - a week later.

Grape processing

A lack of boron is indicated by chlorotic spots between the veins on the leaf and the absence of good ovaries. On soils with a minimal amount of this microelement, new seedlings die within 1.5 years.

Strawberry processing

With a lack of this element, strawberry leaves become dry. To improve the quality of the harvest in early spring a solution of boric acid and potassium permanganate should be poured onto the plantings (1 g of each preparation per 10 liters of water).

Before flowering, it is also advisable to carry out foliar feeding with a solution: 2 g of boron, 2 g of manganese and 1 glass of sifted ash per 10 liters of water.

Processing of ornamental plants

This microelement promotes rapid absorption of calcium and abundant formation of buds. That's why experienced gardeners, actively use this product to obtain beautiful, blooming garden. During the period of bud formation and flowering, foliar treatment is carried out (10 liters of water per 10 g of the drug).

Rose cuttings are immersed for several minutes in a boron solution to prevent fungal diseases.

Drug overdose

Boric acid is classified as the lowest, 4th, hazard class harmful substances. In case of contact with skin, this drug does not harm human health. The danger is that this element accumulates in the body, because it is slowly excreted by the kidneys.

Boron can be a panacea, but it can also be poisonous for plants. After all, an excess of this drug provokes leaf burn. They dry out, die and fall off. Symptoms of an excess of boron in the soil are yellowing of the leaves and curling of their edges. Often the leaves take on a circular shape.

High content of this substance in feed plants provokes the development of serious diseases in animals.

Insect control

Boric acid is not only useful remedy for plants. This drug allows you to fight harmful insects. Dry mixtures with boric acid are often used to kill ants in the garden. This element accumulates in the body of insects and negatively affects their life, which subsequently leads to death.

Boron acts on nervous system ant, causing paralysis and further death. When eating the corpses of their fellow ants, other ants also die. Therefore, to get rid of ants in the garden, very little boric acid is needed.

In order to remove these insects completely, it is necessary to use this mixture for 1 month.

Ant Bait Recipe

There are many recipes using this drug that help get rid of insects. We will look at the most popular:

Boil 2 eggs for 30 minutes. Take out the yolks and grind them with the addition of 0.5 teaspoon of boric acid powder. Scatter the resulting balls near the anthill or on the ants' path.
Dissolve 5 g of the above drug in 100 ml of hot water. Add 10 g honey, 40 g sugar. Stir everything and pour into a jar. Cover with a lid to leave small passages. Place the dishes near the anthill.
1 teaspoon of sugar, 3 egg yolks (boiled), 10 g of dry boric acid, 3 boiled potatoes. Grind and mix everything. Make small balls and place them near the anthill.

Today, the market for pharmacological drugs is extremely wide, for this reason it can be quite difficult to select a drug that has the necessary therapeutic effect. In this regard, from the huge list of medicinal products, it is necessary to select a special product that allows for complex treatment of most diseases. In this article we will talk about a very simple and well-known substance that is used not only in medicine, but also in cosmetology, as well as household is boric acid.

What does boric acid consist of: composition

Boric acid is a pharmacological agent that can be presented as pure form, and as a solution. In its original form, boric acid has the form of a transparent crystalline powder without any pronounced qualities, having chemical formula B(OH)3.

However, for medicinal purposes Most often, an aqueous or alcohol solution is used, which can be sold in various proportions. Boric acid powder is sold in small paper bags, and the solution is sold in containers of different volumes, depending on the type of solvent used to create the pharmacological product.

Methods of using the product in medicine

Boric acid is used for medicinal purposes both in the form of a solution and powder. A particular product is used effectively not only as a means for topical use, wound treatment, douching, but also as a preparation for oral use. It should be noted here that the component is well absorbed through the skin and quickly penetrates the bloodstream, providing a comprehensive antiseptic effect. At the same time, when using the drug for different purposes, you need to carefully read the instructions, since the method of using the drug in each individual case may be different. For this reason, we present a list of situations in which the use of boric acid will be most effective.

How to use the product on the farm

Boric acid is also in great demand on the farm, as it is an effective poison against cockroaches, ants and other unwanted guests. In addition, it is an excellent antiseptic and microfertilizer, which is described in more detail below.

How to poison cockroaches with boric acid

To prepare them you will need equal proportions mix potatoes and eggs, crush them, pour a tablespoon of mayonnaise into a container or vegetable oil, as well as one teaspoon of boric acid powder. All components are thoroughly mixed, and then small balls are molded from the finished mass and placed in areas where cockroaches may potentially live.

Application for plant

A solution of boric acid is an excellent means of foliar feeding of plants.

The described composition must be sprayed on the leaves and flowers, as a result of which flowering, fruit formation and the lifespan of the plant are enhanced. In order to cook necessary remedy, you need to dissolve one gram of dry boric acid in ten liters of warm water, and then start fertilizing the plants weekly.

White or almost white crystalline powder, colorless shiny plates that are greasy to the touch, or white or almost white crystals.

pharmachologic effect

Boric acid has antiseptic and fungistatic activity. Coagulates proteins (including enzymes) of the microbial cell, disrupts the permeability of the cell membrane. A 5% aqueous solution inhibits phagocytosis processes, a 2–4% solution inhibits the growth and development of bacteria. Has a slight irritant effect on granulation tissue.

Pharmacokinetics

Absorbed through damaged skin, wound surfaces, mucous membranes in the digestive tract (if accidentally ingested). Penetrates especially well through the skin and mucous membranes of children early age. When re-entered into the child's body, renal dysfunction, metabolic acidosis, and arterial hypotension may develop.

Boric acid can accumulate in organs and tissues of the body. It is excreted slowly (it accumulates when re-entered).

Indications for use

Dermatitis, pyoderma, weeping eczema, diaper rash.

Contraindications

Hypersensitivity to the drug, impaired renal function, pregnancy, lactation, childhood, treatment of the mammary glands before feeding the child.

Pregnancy and lactation

Contraindicated.

Directions for use and doses

Prescribed for skin diseases (weeping eczema, dermatitis, pyoderma, diaper rash) 3% aqueous solution for lotions. Dissolve the contents of a package weighing 2 g in 65-70 ml of hot boiled water, cool the solution to room temperature and use for lotions. To prepare a solution from an opened package weighing 10g and 20g, measure out half a teaspoon of powder and dissolve in 80-90 ml of hot boiled water, cool the solution to room temperature and use as a lotion.

An aqueous solution is prepared from the powder immediately before use (extempore). An open but not completely used bag of powder should be kept tightly closed. The duration of the course of treatment is no more than 3-5 days.

Side effect"type="checkbox">

Side effect

Possible irritation to sensitive skin. Allergic reactions. It is possible (especially with overdose, long-term use, impaired renal function) to develop acute and chronic reactions - nausea, vomiting, headache, confusion, convulsions, diarrhea, skin rash, desquamation of the epithelium. Oliguria may develop. In some cases, states of shock occur.

Overdose

An overdose can develop through accidental ingestion or inhalation of microparticles of boric acid powder, which is well absorbed through the gastrointestinal tract and through inhalation.

Acute overdose may be accompanied by vomiting blue-green vomit, diarrhea, falling blood pressure, bright red skin rash. Other symptoms may include seizures, fever, epithelial desquamation, anuria, muscle twitching, and coma. Possible death.

Boric acid is highly toxic in accidental overdose in infants and children.

Treatment: gastric lavage (under endoscopy control, it is necessary to exclude the presence of bleeding), infusion therapy, symptomatic treatment, hemo- and peritoneal dialysis.

Chronic overdose boric acid in mammals leads to disruption of hematopoiesis, metabolic processes, reproductive function (signs of toxicity include damage to the seminiferous tubules, epithelial atrophy, decreased sperm count and testicular weight), and decreased testosterone levels in the blood. Boric acid exhibits reproductive toxicity properties and leads to impaired fertility and intrauterine development.

There are reports of neurotoxicity. Effects on brain development (enlargement of the lateral ventricles, decrease in brain mass) were observed in rats at doses higher than those that cause impaired skeletal formation and other developmental defects.

With long-term use medicine over large areas of skin, symptoms of chronic intoxication may occur: tissue swelling, exhaustion, stomatitis, eczema, disorder menstrual cycle, anemia, alopecia.

The use of the drug should be stopped immediately, treatment is symptomatic.

Interaction with other drugs

When used externally, cases of interaction with other drugs have not been described.

Precautionary measures

An aqueous solution is prepared from the powder immediately before use (extempore).

The solution of boric acid should not be applied to large surfaces of the body, nor should it be used for washing cavities and for acute inflammatory diseases of skin areas covered with hair. Avoid getting the medicine into your eyes.
