- Pharmacodynamics
Boric acid exhibits minimal bacteriostatic and antifungal activities 4. Boric acid is likely to mediate antifungal actions at high concentrations over prolonged exposures 3.
- Mechanism of action
Information regarding the mechanism of action of boric acid in mediating its antibacterial or antifungal actions is limited. Boric acid inhibits biofilm formation and hyphal transformation of Candida albicans, which are critical virulence factors 3. In addition, arrest of fungal growth was observed with the treatment of boric acid 3.
- Absorption
Boric acid is well absorbed from the gastrointestinal tract, open wounds, and serous cavities but displays limited absorption in intact skin 4. Following intraperitoneal injection in mice, the peak concentration was reached in about 1.
0-1.5 hr in the brain whereas the value was 0.5 hr in other tissues 4.
- Volume of distribution
Volume of distribution ranges from 0.17 to 0.5 L/kg in humans, where large amounts of boric acid are localized in brain, liver, and kidney 4.
- Protein binding
No protein binding reported.
- Metabolism
No metabolic pathways reported.
- Route of elimination
Regardless the route of administration, boric acid predominantly undergoes rapid renal excretion of >90% of total administered dose as unchanged form. Small amounts are also excreted into sweat, saliva, and feces. Following administration as ointment, urinary excretion of boric acid accounted for only 1% of the administered dose 4.
- Half-life
According to human cases of poisoning, the elimination half-life of boric acid ranges from 13 to 24 hours 2,4.
- Clearance
A case report of acute boric acid poisoning following oral ingestion of 21 g of boric acid presents the total body clearance of 0.
99 L/h before hemodialysis 2.

- Toxicity
Acute oral LD50 is 2660 mg/kg in rat MSDS. Individuals are likely to be exposed to boric acid from industrial manufacturing or processing. Local tissue injury from boric acid exposure is likely due to caustic effects. Systemic effects from boric acid poisoning usually occur from multiple exposures over a period of days and involve gastrointestinal, dermal, CNS, and renal manifestations. Gastrointestinal toxicity include persistent nausea, vomiting, diarrhea, epigastric pain, hematemesis, and blue-green discoloration of the feces and vomit 4.
Following the onset of GI symptoms, a characteristic intense generalized erythroderma follows 4. Management of mild to moderate toxicity should be supportive. In case of severe toxicity, dialysis may be required in addition to supportive treatment.

Boric Acid Uses & Remedies for Body & House
It may sound like a dangerous chemical, but boric acid (BA), derived from boron, is actually an antifungal cure-all of sorts. How so? Well, BA is the key ingredient in a variety of effective and affordable home remedies for some of the most common fungal infections, including athlete’s foot and vaginal yeast infections. And that’s not all.
Do you suffer from frequent eye irritations? An eyewash made at home with BA as the key ingredient can be used to cleanse and fight irritations and infections of the eye. Boric acid eyewash quickly provides soothing relief and helps remove pollutants from the eye.
You might have heard of boric acid being used as a natural pest control as well. It’s true. People have been fighting cockroaches with BA for nearly a century. It’s one of the most effective cockroach control agents ever developed, and it can be used as an alternative pest control for roaches and other unwanted invaders. The awesome thing is it’s less toxic to humans and pets than other harsh chemical pesticides, and it also has several beneficial uses beyond getting rid of pests.
That said, it’s still important to note that boric acid is linked to endocrine disruption, according to research outlined in Environmental Working Group’s Skin Deep Cosmetic Safety Database. So while it is likely OK for home remedies here and there, it’s not something I’d expose myself to unnecessarily. (For instance, in bath bombs or other personal care products.)
What Is Boric Acid?
What is boric acid? It’s a white powder derived from boron and water that has antibiotic properties against both fungal and bacterial infections. The Journal of Women’s Health has found that BA is a safe, alternative, economic option for women with recurrent and chronic symptoms of vaginal yeast infections when conventional treatment fails. (1)
Boric acid (h4BO3) is a white crystalline, oxygen-bearing acid of boron, which is a component of certain minerals and volcanic waters or hot springs. It’s also known as hydrogen borate, boracic acid, orthoboric acid and acidum boricum. You can see from the boric acid formula h4BO3 that it consists of the elements boron, oxygen and hydrogen.
One of the most common and helpful boric acid uses is for nontoxic pest control. The employment of boric acid for ants and other unwanted home invaders actually goes pretty far back. In 1948, it was first registered in the U.S. as an insecticide to control cockroaches, termites, fire ants, fleas, silverfish and many other insects. In combination with its use as an insecticide, BA also prevents and destroys existing wet and dry rot in timbers.
It’s also added to salt in the curing of cattle hides, calfskins and sheepskins. The addition of BA helps control bacteria development and insects. When it comes to agriculture, BA can treat or prevent boron deficiencies in plants.
You can find boric acid in:
- Antiseptics and astringents
- Enamels and glazes
- Glass fiber manufacturing
- Medicated powders
- Skin lotions
- Some paints
- Some rodent and ant pesticides
- Photography chemicals
- Powders to kill roaches
- Some eyewash products
Boric Acid vs. Borax
Both BA and borax are commonly used for pest control. Is borax and boric acid the same thing? Although they are closely related and used in similar fashion, they are not exactly the same thing.
Boric acid is manufactured industrially from borate minerals and brines including borax. BA can be created by reacting borax (sodium tetraborate decahydrate) with a strong mineral acid, such as hydrochloric acid. Centuries ago, Wilhelm Homberg first prepared BA from borax using mineral acids.
Benefits
Boric acid has many health and household uses. Some of the top ways you can use BA include:
1. Yeast Infections
Can boric acid actually work as a natural and effective treatment for a vaginal yeast infection? It sure can. Some experts now recommend vaginal BA capsules as a treatment option for vaginal yeast infections, particularly infections that can’t be cured by antifungal yeast infection medicines. (2) That’s quite impressive.
For yeast infections, you can use boric acid in suppository form before bed for one to two weeks. The CDC reports that this regimen has clinical and mycologic (branch of biology that deals with fungi) eradication rates of approximately 70 percent. (3) A study published in the journal Diabetes Care has even found that vaginal boric acid suppositories were more effective against candida symptoms in diabetic women than an oral azole medication. (4)
Is boric acid effective as a vaginal yeast infection treatment? Some studies reveal that it can cure up to 70 out of 100 women. (5)
2. Roach Killer
Cockroaches can infest homes and restaurants. Not only are they unsightly and repulsive, but cockroaches can pose serious health risks to humans when they find their way indoors.
Cockroaches pick up germs on the spines of their legs as they crawl through decaying matter, which may be transferred to humans through food contamination, which can lead to illnesses such as E. coli and salmonella. In addition, there is a link between cockroaches and a greater occurrence of asthma and allergy attacks as their droppings, saliva and skin sheddings contain potent allergens known to trigger allergic reactions and exacerbate asthma symptoms, especially in children.
Thankfully, boric acid is very effective when it comes to getting rid of cockroaches. These disgusting creepy crawlers succumb to BA simply by crawling over treated areas. The tiny particles of powder adhere to a cockroach’s body and the roach ingests the powder as it preens it from its legs and antennae. The greasy outer covering of the insect’s body also absorb some of the BA. All species of cockroaches are susceptible to boric acid as long as you apply the powder in the areas where the roaches live. (6)
People also use BA to kill ants, fleas, termites, silverfish, beetles, wood borers and other parasites.
3. Eyewash
When it’s heavily diluted with water, BA can be used to create an easy and effective eyewash. Whether it’s a minor irritation or the more serious and contagious eye infection, a boric acid eye wash solution can help eye problems by treating any bacterial infection and soothing inflamed eyes. That includes relief of pink eye symptoms. (7)
In case you’re doubting the use of BA in your eyes, even well-established eye washes list boric acid as one of the main ingredients. (8) To relieve symptoms of eye irritations and infections, a homemade boric acid eyewash can easily be made carefully at home.
4. Acne
Some people recommend boric acid for use in home acne treatments. It also appears as an ingredient in some topical products that treat acne and other skin issues. (9)
Is boric acid safe for skin? BA is naturally antibacterial, and since there is a link between some forms of acne and bacteria (Propionibacterium acnes), it can help kill the bacteria causing breakouts. However, BA is not a foolproof acne remedy and can significantly irritate the skin. Many countries have actually outlawed its use in cosmetics. It also gets a very high (negative) score of 8 out of 10 for health concerns by the EWG. (10)
5. Athlete’s Foot
Boric acid power can also treat fungal infections, such as athlete’s foot and toenail fungus. Just a few sprinkles of the BA powder in your socks or stockings can help clear mild infections and ease the itching associated with athlete’s foot. An added bonus: It can also neutralize the foot odor from athlete’s foot, providing relief for stinky feet.
Why is BA effective at treating athlete’s foot? The acid changes the pH of your skin and helps remove dead skin that feeds the fungus. BA is a seriously potent fungicide, and it often clears up athlete’s foot in cases where antifungal creams have failed. (11)
6. Household Cleaner
You can use boric acid around the house as a cleanser, deodorizer, stain remover, disinfectant and mold killer. You can add BA to your next load of laundry for more stain-fighting power. You can also use it to clean the toilet bowl with very minimal effort required — simply put it in and wait 30 minutes. (12)
How to Use
For yeast infections, you can make your own BA suppositories by filling size 0 gelatin capsules with BA. This equals approximately 600 milligrams of boric acid. The standard yeast infection treatment is to insert one BA-filled capsule filled with 300 to 600 milligrams in the vagina at bedtime for 14 continuous days.
For recurring yeast infections, the standard yeast infection treatment is typically done for two weeks, and then to help prevent the infection from coming back you can use a 300 milligram capsule for five days each month beginning the first day of the menstrual cycle for at least six months. After six months you should stop using the boric acid and if another infection develops, see your doctor. (5)
To make a boric acid eyewash, you should use pharmaceutical grade boric acid powder. First, sterilize an eye cup or eyedropper. Next, mix 1/8 of a teaspoon of BA into one cup of cooled, sterilized water, making sure the acid dissolves completely. If using an eye cup, fill the cup and lower your eye onto it. Blink and roll your eye around several times. If using an eyedropper, squeeze the rubber bulb on the top of the dropper. Then dip the open end into the eyewash. Tip your head back and squeeze the bulb to release the fluid. Repeat several times. Repeat up to three times per day. Always make sure to sterilize your tools each time.
For athlete’s foot, mix BA and rubbing alcohol in the following ratio: two teaspoons BA to one cup of rubbing alcohol or water. Apply to feet with cotton swabs. You can also put the dry powder into the ends of socks or stockings to treat or prevent athlete’s foot.
To kill cockroaches and other unwanted pests, the key to success with BA is proper application. Kitchens and bathrooms are the most common areas to find cockroaches, although any area of a home may become infested if the infestation is bad enough. Cockroaches specifically prefer to live in cracks, crevices and secluded areas close to food, moisture and warmth.
For best results, the powder should be applied in a very thin layer barely visible to the naked eye around the area you think the cockroaches are originating from in your home. Key areas for treatment include under and behind the refrigerator, stove and dishwasher; into the opening where plumbing pipes enter walls; and into cracks along edges and corners inside cabinets and pantries. You want to keep children and pets away from the areas where you apply the acid. Although BA is safer than chemical pesticides, it’s still toxic to pets and children, especially if ingested.
To remove stains and odor from clothing, simply add half a cup of BA to your regular laundry load. You can also put half a cup of the acid into your toilet bowl and let it sit for 30 minutes. Not only does the BA remove stains, but it also removes unpleasant odor.
If you’re wondering where to buy boric acid, you can typically find it in grocery stores or online.
Recipes
Some of the best boric acid recipes are definitely the ones for two common health problems: yeast infections and athlete’s foot. Both of these fungal infections will head for the hills once you introduce BA into the picture.
Boric Acid Vaginal Yeast Infection Recipe
INGREDIENTS
- 600 milligrams BA
- size 0 gelatin capsule
DIRECTIONS:
- Insert one BA-filled capsule inserted in the vagina at bedtime for seven continuous days.
Boric Acid Athlete’s Foot Recipe
INGREDIENTS:
- 2 teaspoons BA
- 1 cup of rubbing alcohol or water
DIRECTIONS:
- Mix ingredients and apply to feet with cotton swabs.
- You can also put the dry BA powder into the ends of socks or stockings to treat or prevent athlete’s foot.
Boric Acid Precautions
Is boric acid safe for humans? As long as you use it correctly and safely, it can be safe. Never use boric acid internally by mouth, on open wounds, or on children. Swallowing boric acid can be fatal. If swallowed, seek emergency medical attention.
For this reason, always keep boric acid out of the reach of children. The infant death rate from boric acid poisonings is high. However, poisoning is considerably rarer than in the past because the substance is no longer used as a disinfectant in nurseries.
When boric acid is used in capsules as a vaginal suppository, skin irritation can sometimes occur. BA should not be used in any way if you are pregnant.
Don’t use boric acid eyewash while wearing contact lenses, and wait at least 15 minutes after using boric acid eyewash before putting your contact lenses in. Don’t use a boric acid eyewash if you have open wounds in or near the eyes. You should get medical help right away if you have any such wounds. Of course, you should also see a doctor if you experience any eye pain, changes in vision, continued redness or irritation of the eye after using a boric acid eyewash.
Never apply boric acid onto countertops or other exposed surfaces, especially those used to prepare food. If boric acid gets on your skin, remove it by washing the area thoroughly. If pure boric acid comes in contact with your eyes, wash them out with cool water for 15 minutes. If you accidentally swallow boric acid, seek medical attention immediately.
Final Thoughts
What is boric acid used to treat? When used properly and safely, boric acid can serve as an effective treatment for:
- Vaginal yeast infections
- Fungal infections like athlete’s foot
- Eye irritations
- Eye infections
- Skin issues like acne
- Household pest control
- Indoor cleaning agent
Boric acid has proved itself to be a potent antifungal to humans as well as a destroyer of unwanted household pests. It’s a strange combination of benefits, but then again, most natural remedies come with many surprising and unexpected capabilities.
It is important to note that boric acid is linked to endocrine disruption. So while it is likely acceptable for home remedies here and there, keep exposure limited.
Boric acid: instruction, price, analogues | Viola FF
Boric acid – according to the ATC classification, an antiseptic and disinfectant available without a prescription.
Boric acid is a white crystalline powder.
Boric acid also has an insecticidal (including anti-pediculosis) effect. The mechanism of its action is determined by the coagulation of microbial cell proteins, which violates the permeability of the cell membrane. In addition, enzymatic proteins are also coagulated, which leads to a disruption in the metabolism of bacteria. It has been shown that 2–4% solution of boric acid acts bacteriostatically, that is, it delays the growth and development of bacteria (Efremova O. A. et al., 2010).
Boric acid is indicated for use in therapy (including complex therapy) of conjunctivitis, weeping eczema, diaper rash, pyoderma, acute and chronic otitis, colpitis in patients over the age of 18 years.
Solutions of boric acid are used for lubrication of affected surfaces, preparation of dressings and turundas (instruction of the Ministry of Health of Ukraine).
Boric acid: a place in the treatment of chronic suppurative otitis media
Chronic suppurative otitis media, also often referred to as chronic otitis media (COM), is a chronic inflammation of the middle ear and mastoid cavity, characterized by discharge from the ear (otorrhea) through a perforated eardrum (Head K., 2020). This is one of the most common chronic infectious diseases in the world (Adriztina I. et al., 2018). In addition to otorrhea, one of the main clinical manifestations of CSR is hearing loss. There may also be discomfort and pain in the affected ear. Hearing loss can lead to disability and impair speech and cognitive development. In addition, socially, it impairs the patient’s communication capabilities and limits his employment prospects, significantly reducing the quality of life (Head K., 2020). Complications of CSR can be extracranial (such as mastoid abscess, postauricular fistula, and facial paralysis) and intracranial (such as otogenic meningitis, cerebellar abscess) (Adriztina I. et al., 2018). Treatment of CSR is usually complex and includes both the use of systemic antibiotics and topical antibiotics, antiseptics, NSAIDs and glucocorticoids. Antiseptics can be used in the form of drops injected into the ear canal of the turunda, moistened with an antiseptic, or rinsing with a syringe. If conservative therapy fails, surgical treatment may be performed. In one of the studies, the effectiveness of the use of instillation of an alcohol solution of boric acid in the relief of otorrhea in CSR was demonstrated in comparison with the placebo group. Another study showed that topical application of boric acid solution is more effective than application of acetic acid solution (Head K.
, 2020).
Difficulties in the treatment of chronic infectious processes, including chronic otitis media, are largely associated with the formation of biofilms, since the bacteria inside the latter are resistant to most antibacterial agents. It has been established that boric acid destroys biofilms of many bacterial strains. One of the reviews, which included 24 studies, also recorded the effectiveness of the use of boric acid in the treatment of CRS. At the same time, the absence of ototoxicity was demonstrated when using solutions of boric acid containing less than 4% of the active substance (Adriztina I. et al., 2018).
Other applications of boric acid
Since boric acid has fungistatic properties, it can be used as part of solutions (talkers) in the treatment of malasseziosis (Sinitsa V.I., Sinitsa P.V., 2006).
Erysipelas (erysipelas) accounts for about 20% of all purulent-septic diseases in surgical practice (Efremova OA et al., 2010). One of the studies demonstrated the effectiveness of the combined use of solutions of boric acid and dimexide after dermatotomy in the complex treatment of complicated forms of erysipelas. The use of a solution containing boric acid and dimexide allows both to reduce the bacterial contamination of the affected surface and helps to cleanse necrotic masses, reduce the severity of edema and epithelialization (Efremova O.A. et al., 2010). This treatment regimen is also effective in erythematous-bullous and bullous-hemorrhagic form of erysipelas (Efremova O.A. et al., 2009).
Boric acid: conclusion
Boric acid is an affordable antiseptic and disinfectant, produced in the form of a powder for preparing solutions and ready-made alcohol solution. Despite the huge number of different antiseptics for local use on the pharmaceutical market, boric acid is still widely used in the treatment of various skin, gynecological diseases, and ENT pathologies. At the same time, one should be aware of the inadmissibility of the use of boric acid preparations in children due to its toxicity. British Pediatric Association at 1966 recommended the discontinuation of the use of drugs containing boric acid in infants and children.

Is it possible to drip boric acid into the ear?
The answer is no. Currently, doctors do not prescribe such prescriptions. In water, boric acid does not dissolve well, and 70% alcohol, as a base, is too harsh and can harm the middle and inner ear. In addition, the absorption of boric acid into the blood should not be allowed. You can read about other medicines against otitis media at the end of the article, the paragraph “Analogues”.

Overdose
Cases are described when children took boric acid powder orally, there were deaths. The toxicity of this substance is very high, the drug is rapidly absorbed and damages the functioning of the kidneys and other internal organs, accumulates, but is difficult to excrete. It is dangerous for children to apply even on the skin, as the medicine enters the bloodstream through the damaged surface and mucous membranes. At the slightest suspicion of poisoning, you should immediately call a doctor.
Boric acid
Analogs
In medical practice, you can find many modern and non-toxic products for topical and external use. For example, Betadine solution based on povidone-iodine. It is also applied to damaged skin. It is widely used in hospitals in the treatment of wound infections, ulcers, in preparation for surgery, in dentistry.
Safe for mucous membranes Chlorhexidine. It is used as an antiseptic in gynecology, dentistry, for treating burn wounds, for disinfecting the patient’s skin and the hands of staff. If povidone-iodine has a small risk of absorption, then Chlorhexidine does not have such a danger at all, it is a very mild drug.
Perhaps the most powerful antiseptic for local use is Miramistin. In addition to its antibacterial action, it has an antiviral and antifungal effect. The drug enhances healing, stimulates local immunity, it does not inhibit the cells of the human body, as a result, epithelialization occurs faster. Miramistin is just indicated for the treatment of acute and chronic otitis and many other pathologies.
Safe over-the-counter drops for ear inflammation are available at the pharmacy. These are Otipax, Otirelax, Maxicold Ototita. All these drugs include the anesthetic lidocaine and the anti-inflammatory component phenazone. Eliminate pain and inflammation quickly. The active ingredient in Otinum is choline salicylate, an anti-inflammatory agent.
Conclusion
Currently, boric acid for humans is more often used to disinfect equipment and premises, and in the pharmacy sector, its sales have given way to more modern antiseptics. If the surface of the skin is not damaged, boric alcohol is suitable for disinfection, but this is rare. Considering that the risk of absorption into the blood is high, it is easier to choose Chlorhexidine or Hydrogen Peroxide. With otitis all the more difficult. Let’s start with the fact that it is extremely difficult for a person to determine what kind of otitis he has: external, middle or internal.
