Boric Acid as an Eye Wash




thumbs up sign Hello. For what it may be worth:

According to my old bottle of MK boric acid powder's directions: "AS AN EYEWASH FOR TIRED EYES...Prepare a solution by boiling one level teaspoon to a pint of water. Use warm. Store in sterile container. Prepare sufficient for one day's use and discard unused portion."

Because I have one and want all the more to be careful to avoid a waterborne infection, I use a silver/ceramic filter on my tap water before I boil it with the boric acid powder.

Thanks.

thumbs up sign I too grew up with this solution in my home during the "50's no doubt the product was more authentic than as today since the government started to break it down to promote other brands, which are considered to be a slow deadly poison, if issued internally, can cause heart attacks or blackouts, so we're darned if we do or don't. All I was told is that the Boric Acid ward's off certain pollution in the air, I believe that it was also used as a douche cleanser.

Q. My father mixes boric acid purchased at Phar Mor mixes it with water to wash his eyes. Is this safe even though it is (an insect) poison?

George Kipples

A. Hi George. What does the label say? -- I'm not really asking for further detail -- I'm making the point that things should be used only for their intended purpose. I feel an insecticide does not offer enough purity assurance to put in your eyes :-)

When I was younger, boric acid was widely used as an eyewash, and in those days everyone thought it perfectly safe. Most families had a box of it and an eyecup in the hall closet.

opinion! But today the pharmaceutical mega-corps own the FDA and our political system, which has made it impossible for the citizenry to know whether traditional cures are dangerous or whether the mega-corps just decided that cheap generic remedies should be outlawed to protect their $210 per dropper-full business ... because the revolving door bureaucracy has set it up like this:

The FDA calls traditional cures "new drugs" -- which means they can only be sold after multimillion dollar clinical trials. But because they are traditional, cheap, generic, and non-patentable, obviously there is no one who can recoup the millions of dollars that would be needed to do the testing, so the FDA is able to fulfill the wish of the pharma giants and simply pull the products. It's happened to many traditional cures, although I don't think boric acid powder is actually outlawed from sale like many other traditional cures are.

If your government actually cared about high healthcare costs, they'd have the FDA run tests on traditional cures or give a grant to a university to run the tests, so we'd actually know -- but it can't happen until we refuse to vote for any politician who accepts donations from big pharma, the banks, and the megacorps :-)

That leaves all of us here with "I would guess it's safe, but I can't really claim so, because no clinical tests have been run, nor will they ever be run under our corrupt system".

We see the same corruption in the abuse of our patent system by the pharma industry. The original idea was that public monies would be used to protect an invention from being copied for a number of years in return for the public benefit of everyone being able to freely use it thereafter. But with pharma patent extensions and tweaks, it seems that no drug of value ever becomes public domain, does it? The benefit all flows in one direction, with your money & mine going to protect big pharma and their endless patent extensions, yet we keep voting for the same politicians who take big money from the industry :-(

A. Boric acid has been used for many decades as an eye wash. When used, very diluted in water, it can be used as an emergency eye wash or as eye drops for eye infections. It can also be used safely as a pesticide. It is poisonous to bugs not to humans, and can be used as a pesticide around children. Boric acid also can get through many materials, such as wood and can have lasting effects as a pesticide. It is safe for your father to use this as an eye wash. This method was popularized in the 40's and 50's so his mother probably showed him this. However, why is he using this every day?

A. Patricia, I really think you should ask your doctor or a pharmacist. If you get an answer on the internet, from a stranger with no qualifications, and maybe even with a fictitious name and an intent to harm, are you really going to put that in your son's eyes?

A. Hi,

Last year I had an infection in my eye, I don't know what it was, probably a cold or conjunctivitis. My friend's mother used boric acid with water, about half a teaspoon in a cup of water and put it in my eye. Cleared up in about two days. My friend uses boric acid to kill cockroaches; he puts it around the house. It is poisonous to bugs, but not to humans.

A. Boric Acid solution (mix 1 tsp powder in 1 pint boiled water; let cool completely before using) has been used for decades in treating minor eye irritations/infections. Its routine use disappeared with the advent of antibiotics eye drops/ointments. Boric Acid is still a very useful therapy in non serious cases. It is much better than vasoconstrictors (used today for minor irritations), and a hundred times less expensive. Prepare a solution, keep it in a closed glass or plastic container, and use it when needed with an eye cup, Q-tip [affil links] or eye dropper several times a day.

A. Woah ... now I came across this thread while searching the web on HOW poisonous boric acid is because it IS poisonous to humans if ingested.

The benefits of using boric acid to control bugs over using Raid or similar product are:

1. Much cheaper. You can buy boric acid powder and mix it with something to make your own bait or buy already prepared harris roach tablets at any grocery store for $3.

2. Bugs do not develop long term resistance to boric acid. The same boric acid has been used for centuries while the chemical insecticides have to constantly change their formulas because bugs become resistant.

3. LESS poisonous if ingested and not poisonous through skin. Chemical insecticides can poison you through contact, but not boric acid. It is harmful to bugs through contact but not to humans and pets. According to Harris Roach Tablets web site, you can eat a whole tablet and it wouldn't harm you. But if you eat a bunch you'd most definitely die. But a child or a dog or a cat wouldn't have an urge to eat a bunch because it tastes awful.

It is safe as an eyewash and in fact is the same thing contained in over the counter Bausch & Lomb eye wash that can be used daily according to the bottle. I have no idea what concentration, although you'd probably want to use distilled water.

Q. We used a Boric Acid eyewash for our toddler (now 16) with good results. I now am caring for a litter of 6 week old kittens who are recovering from an upper respiratory infection. They have received expensive prescribed eye drops for about two weeks. There is some residual eye inflammation left. Does anyone know if this same eyewash could be used for the kittens?

A. My mother used Boric Acid Solution (not the powder, must be the solution). She mixed 50% Boric Acid Solution to 50% water as an eye wash when we were children and it worked every time clearing up "Colds" in our eyes. I have also used this today. Not only in my children, but also as an eye wash for my dogs during the winter months when they get colds in their eyes. And yes, boric acid can be used as a pesticide. It is slow acting but very effective.

A. Boric Acid powder can be purchased at virtually any drugstore. I bought a bottle at Rite-Aid yesterday for my kitten. It comes in a bottle 5-6 inches tall, similar to the type of container in which you might purchase fish-oil capsules or vitamins. It is very inexpensive and effective.

A. I am 52 years old ... and my mom used boric acid as an eyewash to clear up sties, etc. for us as children. I came to this website today to find info about the water-to-powder mixture and reading one of the responses answered my question right away.
I had difficulty finding boric acid, and the pharmacist within a local Kroger grocery store ordered it for me at $5.99 for 6-oz. powder canister. The pharmacist says it will not harm humans, is good as an eyewash.. because of its antibacterial qualities.
Be sure to boil the water, let it cool, then add the powder mixture. I'm using this to clear up an eye infection in my pet dog.
It really works great !

A. Thought you all might like some technical information on this subject

... By J.R. Blasius
"Borates, including boric acid, have been used since the days of the ancient Greeks for cleaning, preserving food and other everyday activities.

"Today, boric acid is found in more every day uses and products than ever before. Among them are eye wash solutions, flame retardants, insecticides, glass products and fertilizers. And yet with all these uses over all these years, the question, "Is boric acid toxic?" seems to be raised with regularity every year. Asking "How toxic is boric acid?" is sort of like asking "How hot is hot?"

"The answer clearly needs to be qualified...and, yes, scientists have figured out a means to compare one chemical to the next. In fact, on this scale, scientists and/or regulators can compare most anything that can be swallowed, inhaled or put in one's eyes. The scale I am referring to gives a figure known as the LD50 rating - a dose that would cause the deaths of 50 percent of a specific animal population.

"One method used to determine the LD50 rating for most substances is via laboratory-controlled oral doses to rats. The following table lists the LD50 (oral-rat) for several common substances as published by the Registry of Toxic Effects of Chemical Substances.

"Substance LD50 (milligrams of dose /kg of body weight) Aspirin 1,000 Boric Acid 2,660 Table Salt 3,000 Boron #10 3,500 Baking Soda 4,200 Grain Alcohol 14,000 Based on this data, boric acid and Boron No. 10 are not significantly different in toxicity than common table salt. In addition, both boric acid and Boron No. 10 are less toxic than aspirin. The greater the LD50 rating the safer the substance is.

"When compared to these common household items, boric acid and Boron No. 10 are not particularly dangerous, and, if used properly, will not cause poisoning. It is important to remember that there have been no known deaths resulting from the use of boric acid or Boron No. 10 in mattresses or upholstered furniture or even in their use as an insecticide.

So are borates toxic?
"Certainly, and so is virtually every and anything else you come in contact with. It is simply a matter of quantity, and the simple fact is that exposure to cotton batting treated with borates is a safe exposure that should not cause alarm in anyone.

"In fact, the levels at which these borate products are present in cotton batting make them very effective control agents against dust mites, mold and mildew, all of with can develop in any mattress of any construction. Controlling the spread of dust mites, molds and/or mildews makes for a healthier home and less of a chance for the homeowners to develop allergies.

"If you believe aspirin or table salt is dangerous, poisonous or in some other way life threatening, then you probably should not use borates.

"If, on the other hand, you can rationally look at the comparative data, you will probably come to the conclusion that boric acid and Boron No. 10 are among the safest of choices for making cotton-batting flame retardant."

A. Dear Ms. Howard,

My mother always washed her infant children's eyes with boric acid solution in the 40's and 50's. She had five children and never had a problem with it. The doctors at that time recommended it. I followed suit and washed my three children's eyes with it. When they were infants the tear ducts would get clogged and there would be some pus. A little boric acid solution on a fresh cotton ball a couple of times a day would cure the problem. I also used it on our pet dogs and a litter of cats over the years. Works like a charm. We always boiled one cup of water and then added one teaspoon of boric acid water and stirred. It makes a mild solution. I would make a fresh cup after a couple of days. I would keep it in a cup with a saucer on top to keep it clean at room temperature. The 50% boric acid to 50% water solution that I read about in another email sounds too strong to me. Guess you have to use your judgement. Good luck.

Melvin Johnson

Ed. note: It's probably fine as a roach killer, Melvin. But there are purity standards for chemicals depending on their end use, and I would certainly not put this stuff in my eyes; even if it is, generally speaking, boric acid, it is not of guaranteed purity.

A. For use as an eyewash it would be wise to obtain medicinal (USP) grade boric acid. A technical grade meant for insecticide may have impurities you wouldn't want in your eye. I believe a nearly saturated solution is what you want, but without any undissolved crystals.

Q. I have read all that has been posted about Boric Acid. I am looking to see if anyone has used Boric Acid on Boer Goats as treatment for the eyes? I have a baby Boer with a mild eye infection and several old timers have told me to use it. What do you think? Has anybody out there ever heard of such a thing? Desperate!

A. Just adding my 2 cents worth here. In the late 1940's and early 50's, my mother-in-law was a nurse... head of pediatrics at the main hospital in Chicago. She gave me her recipe for a boric acid solution when my kids were small. So, yes, a boric acid solution was and is an accepted and useful medication for irritated eyes. Her "recipe" is for a 2% solution: 1 tablespoon boric acid to 1 pint of purified water (boiled or distilled). Also, if it doesn't clear up the problem, see a doctor.

thumbs up signVery interesting on boric acid for eye wash. I was at the local Rite aide today and the pharmacists (2) didn't know very much about this treatment. In fact I was in the eye drop section..didn't read what was in the eye drops...and they said there is nothing in that section for "cold in the eyes". Well they are younger and didn't have the wise mothers of the 50's....haha So they referred me to the first aid section to get boric acid powder. Thanks to your website as I didn't know the mixture for homemade solution.

HAHAHA..she did think at first I was crazy but I sent her some of the posts from here. If she didn't believe me she did believe all of you. I remembered using it on the kids when they were little. However, I did tell her washing their hands and not touching the eyes was the best. Just wanted to share this. Patticakes

Q. I have seen recipes from 1/8 Tbsp to 1 Tbsp mixed with 8 oz boiling water to clean eye stains from Persian cats. Never mentions putting it in their eyes, just wiping the stains on the outside. However, all breeders and my vet say it is ok to use the same type saline solution I get for my contacts as an eyewash for my Persians. Think I'll start with the 1/8 tsp as I'd rather have a little brown under their eyes that hurt them. On the bug stuff.... Me with cats that go outside in my yard a couple hours a day, how does one use the boric acid as pest control. Mix in a spray bottle - has anyone with pets used this and if so what mixture?

A. I have used Boric Acid for conjunctivitis (pink eye) as well as cats, kittens, dogs and puppies. The instructions on my container from Rea and Derick is as follows- Directions: To make a solution, dissolve one tablespoon in a pint of boiled water. If intended as an eyewash, prepare a solution by boiling in water and store in a sterile container. Prepare sufficient quantity for one day's use and discard unused portion. Based on the recommended ratio.... I prepare 1/2 cup boiling water with 3/4 tsp Boric Acid (3 1/4 leveled teaspoons) or 1 cup boiling water with 1 1/2 leveled teaspoons Boric Acid. Err on the side of using less Boric Acid. I dispose of remainder after 24hrs.

Wash the container, measuring spoons, plastic stirring utensil, and eyewash cup in soap and water. Then sterilize all above and place on a paper towel.

I sterilize my 1 cup Pyrex measuring cup by pouring boiling water inside and outside thoroughly. I then boil 1 cup of water (preferably distilled or sterile water, but I have had no adverse affects with well water) in the sterilized cup with the Boric Acid. Cool before use. A saturated cotton ball will work, but I prefer the eyewash cup available at a pharmacy.

I used the same proportions for pets. (Perhaps I was incorrect but within 3-4 days their eyes clear up.) If in doubt call an older veterinarian who is more familiar with Boric Acid usage.

Tonight my pharmacist mentioned his sister uses the Boric Acid solution for irritated eyes from allergies.

If someone has used Boric Acid as a pesticide, please advise ratio and proper usage against what insects, etc.

Thank you.

A. I have used the following as a very effective control for ants. Ant bait recipe: 1 tsp boric acid (readily available at pharmacies) 6 tbsp sugar (white) 2 cups boiling water add first two ingredients to boiling water. Stir well. Cool. Dip cotton balls into solution and drop into a plastic container that has holes punctured into sides along bottom of container (to allow ants in and out). Put the lid back on to keep out wasps, bees and to prevent evaporation. Place the container along the regular path of ants. Check the balls every few days and remoisten as required. Keep using as long as ants continue to appear.

Q. Can anyone find Boric Acid Crystals? I've never seen this Boric Acid Powder when I went looking for the crystals at the pharmacy. The pharmacist looked at me like I was crazy. Does anyone know if there is a difference for the amount used to make an eyewash solution between the crystals and the powder. Seems to me that the powder would be a bit stronger than the crystals if measured in the same amount as the crystals because it is finer. It is awesome on infections made into a paste, although I've never heard it being used as a bug killer.

A. My father and me got conjunctivitis when we were living in Subic. He was working at the U.S. Naval Base then and the Navy doctor gave him a bottle of 2% Boric acid solution for eye wash.
I got the "sore eyes problem" a week ahead of him and I think I infected him. My eyes were starting to show very red rings (getting worse) despite using medications given by a local doctor.
The 2% solution cleared my ailment and my father's in three days!
Simple, cheap and ancient remedy and yet so effective.

A. Be careful to use the powder and not the crystal form of boric acid. Make sure it is pharmaceutical grade, not bug poison. Don't put bug poison in your eyes. There isn't much control on the contents of bug poison to make sure it isn't going to hurt your eyes. To reiterate a previous post, undissolved crystals can scratch the cornea. If unsure of the recipe, start with the weakest, and increase the proportions if no result in three to four days. Proportions mentioned range from 1/8th teaspoon::8 ounces water, to 1 tablespoon::16 ounces water (too rich for me). No results in 7 days with the stronger mix, see a doctor. Water should be sterile distilled water (boiled and cooled to body temperature). Use what you need, store while using in a refrigerator in a sealed container. When done with that eye problem, throw it out. And keep washing and sanitizing your hands, before and after use.

Try to keep your hands away from your face. Cotton (cotton!) balls can be used to wipe clean eyelids and tear duct areas, NOT YOUR EYEBALL! Any dropper or eye wash cup should either be disposable or sterilized with 212 °F water for 2 minutes before and after use. As always, remember this is free advice, worth every penny you paid for it. For advice worth more, see your family doctor.

Boric Acid as an automotive lubricant or grease additive.

I read a patent sometime ago that spoke of boric acid increasing the slipperiness of oil or grease when added by some ridiculous margin of something like 8000 times slipperier! It stays so at high temperatures making it just fine inside a car engine.

Some googling turned up quite a few people that use it as either a fuel additive or engine oil additive to decrease friction and so make a motor last longer, run quieter and more economically.

I purchased a used car a year ago and added some home made boric acid powder to my engine oil (about 1/2 a cup). 20,000 kms later and It didn't blow up yet. I didn't have enough data on fuel economy as I did this as soon as I got the car but did notice it running smoother.

I've also worked some of the the acid powder into some grease with a putty knife and have greased all kinds of things with it. Hard to know quite much it has helped things along but rub some between your fingers and it really does decrease friction.

At your own risk people but interesting all the same. Youtube can teach you how to make it from borax [affil links] and spirit of salts but it's so cheap to buy as I later discovered.

Q. I recently asked a Pharmacist why I could not find an eyewash with boric acid in the USA. He replied that the FDA no longer approves of this item. I still find it available in Mexico, but it's fairly expensive.

A. Hi Herbert. You can get an eye wash from Bausch & Lomb which contains boric acid though.

Your pharmacist may be right that "the FDA no longer approves of this item", but do not read into it that they necessarily have any particular reason to DISapprove of it :-)

opinion!  Rather, corruption has consequences, and the FDA, a revolving door regulatory agency run by the pharmaceutical companies themselves, has decided that virtually all traditional cures are to be considered "new medicines", not sellable until expensive clinical trials are run -- knowing full well that nobody can sponsor the rigorous clinical trials they require because no money can be made from non-patentable medicines. It was a stroke of genius for the FDA to declare that they will test nothing themselves, and only allow things that have been clinically tested by others. My last eyedrops were $210 for a quarter ounce vial of something which might not even work as well as boric acid, but under our current system of political prostitutes we'll never know.

A. I found Boric Acid Powder (100%) at Dollar Tree - $1.00 for 5 oz. It was/is labeled as Roach and Ant killer.

! Hi Bev. I wouldn't put something so labeled into a person's eyes though. Just as a Subway "five dollar foot long" should not be used for precision measurement of things, boric acid intended for insecticide use may not be pure enough for other uses (even a small amount of any contaminant could be bad for your eyes).

A. Boric acid: For Molluscum, I find that that 1-3 teaspoons of 99% pure boric acid powder in 1-2 cups of pure water dabbed or sprayed on my skin will help the body to get rid of molluscum. I found 99% pure boric acid powder at Duda Energy.

I successfully use it as my eyewash. I also use the same formula as an earwash and I sometimes use alcohol instead of water for swimmers' ear. I found the same formula stops warts. I have also used the same formula as a vaginal douche (boric acid vaginal suppositories [affil links]). Anytime I see a cockroach, I put the pure powder into every crack and crevice I can see and this gets rid of roaches for me. I have also done the same for termites and it worked for me. I have had lots of experience with boric acid for many years since I am a senior elder. Boric acid is a lifelong pantry staple for me.

Q. Hi, I read a lot about boric acid. I now remember my mom used it on us when we were young.

I wonder if I can use Borax for the eyes. My son has a stye in eye.

Or should I find boric acid?

A. Hi Linda. BORAX IS NOT BORIC ACID! Just because things sound similar doesn't mean they are. I would suggest Visine, Murine, or some other commercial product which lists boric acid as a primary ingredient rather than trying to make your own eyewash -- or ask your pharmacist. Good luck.

A. I put 1/2 to 1/4 teaspoon Boric Acid in 1 cup distilled water warm the water if you want and wash the eye out with it. Be sure to stir and mix really well. It soothes the eye then either spray Vetericyn in the eye or put Neosporin in the eye
It surely helps the eyes of our dogs and horses. The Boric Acid in the distilled water soothes the eyes. The Vetericyn is really a good remedy also.

It will help all infections in the eye but do see a doctor if it does not clear up.

A. Thanks, Delores.

Hi Readers. Please note that "Vetericyn" is a trade name for a range of products, from anti-itch sprays to shampoo, and one of which is 'pink eye spray'. Similarly, the Neosporin line includes some ophthalmic products. To avoid misunderstandings, please don't take internet advice about such things but carefully read labels & instructions for products.

! I had a case of eye mites, demodex mites, a few years back. What a plague. I used all the commercial products which are just pieces of paper towels cut very small, saturated with commercial solution, individually wrapped in a box and very costly. I even saw an eye guy (doctor, optometrist, opthamalogist, I don't remember) who could offer me nothing. Online says almost everyone over 70 will get them. I was 72. Finally used boric acid remedy found online for the demodex life cycle and that did it! I think I used 3/4 tsp in 1 cup distilled water heated to dissolve but for your sake, look it up, start with caution. No eye problem ever developed from the use and I still use it on occasion if my eyes start itching. There are other uses for boron/boric acid that I use or am investigating. It's sad at least, criminal at worst, that these simple, inexpensive remedies are being outlawed as quickly as possible.
