I am currently 54 years old and have had problems with getting prolonged and painful secondary sinus and ear infections along with every cold or flu I contract, ever since I was a kid. I have eczema and a few allergies so, over the years, I have been prescribed so many different courses of cortisone and antibiotics that by mid adulthood my poor immune system was pretty much shot. It seemed as if there was a bug within 10 miles of me, I would catch it. I was just tired of it.

So, last year, after speaking with a friend who had much success boosting her own immune system by using probiotics, I decided to also give probiotics a try and vowed to commit to using natural therapies whenever possible to try to boost my immune system back to health. And then, just as things seemed to be going so well, I caught an aggressive upper respiratory bug that was going around my office. As was typical for me, the virus itself ran its course in about 7 or 8 days, but I was left with a horrible sinus infection that just seemed to keep hanging on and was getting worse. It was making life miserable an just about knocked me out.

Since it was the height of cold and flu season, I was unable to get an appointment with my doctor, who would have just prescribed antibiotics for the sinus infection anyway, something I had worked the whole year to avoid. Then, I stumbled across an article about adding 1 tablespoon of hydrogen peroxide to your regular neti pot solution and thought what the heck, I would give it a try.

The formula is this: I empty one dry saline mix packet (I get the over-the-counter packets, they're pre-mixed, easy to use and buffered right so they don't sting) into a clean, sterile neti pot first, add 1 tablespoon hydrogen peroxide (no more than that or it will be uncomfortable and could irritate the lining at the back of the nasal passages), then fill the rest of the pot to the inside rim with distilled water, put the lid on and give it a few shakes to mix it well. Then use the rinse as usual. I do half the solution on one side of my nose, then switch and use the remaining half of the solution on the other side, for a full sinus rinse.

I did this 3 times a day for 5 days - Once when I got up in the morning, once when I got home from work, and once right before bedtime. I could immediately feel (and see) the difference when adding the hydrogen peroxide to the neti pot rinse.

Within 3 days the sinus infection was gone and within 5 days the swelling in my nasal passages had abated and my nasal muscus was back to clear. After that, my cough cleared right up as well because I had no more infection seeping down into my lungs from the sinus infection.

I have not had a sinus, ear or lung infection since. I continue to add a tablespoon of hydrogen peroxide to my regular neti pot solution in this way whenever my sinuses feel a little "iffy." It could be allergies, or it could be a virus. Either way, adding in the hydrogen peroxide has worked wonders for me.

In addition to this sinus rinse, I also use several drops of straight hydrogen peroxide in each of my ears for about 10 minutes each side to ward off cold and flu whenever I have been exposed to sick people. It works great to keep the ear canal clean and free of wax buildup, too.

I am a firm believer in hydrogen peroxide and its healing properties and I will also be adding Bill Munroe's inhalation technique to my repertoire of holistic remedies in the future.

My hubs had a constant severe sinus infection for 3 months. He had a very bad headache. He went to 3 different doctors and 2 runs of antbx. with only 1-2 days of relief. Also a chiropractor, without results. Used flonase, and claritan daily, took 3 tumeric and fishmox daily. No relief. We began to wonder if he had a tumor.

He was desperate, so he tried 4 parts distilled water to 1 part 3% hydrogen peroxide, flushed sinus with neti pot and then let it bubble in nose for 5-10 minutes, (burns a little). Suddenly a profuse amount of mucous began to bubble out, flushed several times, and let it set afterwards each time, at which each time large amounts of thick mucous bubbled out of his sinus. All through the day, it would continue to pour profuse amounts of thick mucous.

This was finally the answer, Praise God some relief.

I have used hydrogen peroxide for sinus infections and it does work. You need a neti pot, I use the one from the chemist that comes with the saline sachets. Put 1/2 to 1 sachet into the pot and dissolve with small amount of really hot water. Then top up to a warm water temp up to the line marked on the bottle.

Then mix in a teaspoon of Baby Shampoo and give it a shake to make it sudsy. The baby shampoo will help to dissolve the bio films that protect the bacteria from both the salt solution and antibiotics.

Use this to rinse your sinus, but especially hold some of the mixture in, tip you head upside-down and really let the mixture get into the upper sinus. Breath in through your nose at the some time to bubble and wash the mixture. Tilt your head one side for 20 seconds, then the other. Let the mixture out, then squeeze some more up there, but this time hold your head parallel to the floor then tip one side for 20 seconds, then the other. This will address the sinus cavities under your eye sockets. Use up remaining mixture to flush.

Then you need to mix another neti pot mixture adding some peroxide.

Start with 1/4 teaspoon of hydrogen peroxide and go up from there depending on tolerance. Repeat whole procedure to target upper and middle sinus cavities.

People have posted about the pain of the sinus wash. I can tell you that when your sinus is infected the wash does hurt. Just washing an open wound would hurt or sting. But...if your sinus is healthy, it does not hurt. You can feel the peroxide bubbling and oxygenating, but it's not at all painful. So with your sinus infection, start with a small amount of Baby Shampoo and Peroxide and work up to larger amounts. As your sinus begins to heal, you will find you can tolerate more of the peroxide.

I would like to add, when you use peroxide, it doesn't just wash out the bad bacteria, it washes out ALL bacteria, good and bad. So it's a good idea to use some probiotics. Some people put the probiotic powder into a saline solution and flush the sinus to in the hope that some of the probiotics will stay put and re-colonise the sinus with good bacteria. I personally put the powder on the back of the tongue at night when I'm going to sleep and let it naturally migrate its way up into the sinus.

- Hope this helps. xx

You know, all of these comments sound sort of complicated.

Here's what I do: dip a couple of cotton swabs in h2o2. Insert the swabs into the nostril at a time (I do both at the same time.) Ease the swabs back until only an inch is sticking out...and leave them for a minute or so. (Often it makes me sneeze.)

After you remove the swabs give your nose a good blow. Voila! I do this two or three times a day if I'm sick. It's definitely great before bed if you're congested. And it keeps a sinus infection from grabbing hold.

Hydrogen peroxide should be diluted at least 10-20 times its normal (3%) strength. A 4:1 dilution as stated here will burn your nasal mucosa severely and delay healing from the sinus infection. There is no good medical evidence for its use in the nasal sinuses. I am a doctor who has tried hydrogen peroxide and suffered mucosal damage with a 4:1 dilution with water.

I am highly allergic to cedar and elm pollen and living in Houston, does me no favors! For the past three weeks, the two pollen's have wreaked havoc on my sinuses, which in turn, turned into a nasty sinus infection. I have been getting chills on and off, waking up every morning about 12:30 blowing my nose and hacking. I could smell and taste infection and was hacking up and blowing thick green stuff. I wouldn't be able to fall back to sleep until about 4ish. I have to get up at 5:30 for work. I have been feeling sick, tired and cranky. All of these years that I thought that it was my lungs giving me problems, but I think it has been chronic sinus infections! I don't have insurance, so going to the doctor to get antibiotics is out of the question as I am on a super tight budget.

I decided to come here and saw the Hydrogen peroxide cure and decided to take a shot in the dark.

I have a plastic neti pot. I know that table salt is a no-no, but it's what I had available, so that is what I used.

I used 1/4 teaspoon of salt and two teaspoons of hydrogen Peroxide in warm distilled water and cleaned out each nostril.

I did that when I got home from work and did it again before I went to bed. I also did it this morning before work.

The "sick infected" feeling that I had along with the chills; GONE! I slept all night! I could taste my food again and could smell again which told me that my husband had lied to me about smoking in the house, because I smelled it! He got an earful! LOL!

I will do this again when I get home from work. I am in awe of this inexpensive and highly effective treatment! For about $1.00, I am almost 100%, where a visit to the doctor along with scripts, would have cost me about $400 or more.

For those of you not getting results with hydrogen peroxide. Remember, it is good for only about 6 months after you open the bottle.

So get yourself a new bottle. When you open it, write the date on the label so you know when it becomes unusable.

A sealed bottle is good for about 3 years if you keep it in a cool environment. But once you unseal it, you only have 5-6 months before it degrades and becomes ineffective. Also, don't dip anything like a q-tip or finger in the bottle. That makes it degrade faster.

If it doesn't fizz, it's likely degraded. I learned this the hard way with a sinus infection that wouldn't go away. My bottle had been open about a year. As soon as I got a new one, things changed and it started working.

Check Google for more information about the lifespan of hydrogen peroxide. Hope you are able to resolve your health issue whatever it is.

It seems I might have written this already, but it's worth mentioning again: for any lung and/or sinus issues, we have seen enormous success with this simple h2o2 breathing technique: about 4-5 times a day, spritz two-three second's worth of h2o2 (plain drug store kind) in a mug of boiling water and just breathe the vapors. No need for towel or any fancy stuff. Within a week one will be hacking up and/or blowing out through the nose, all kinds of nasties (which almost scared someone into stopping, but thankfully they persevered) and within a month or maybe a month and a half, no more snoring, no filling up endless tissues, more energy (maybe from more oxygen getting to where it should) etc. Later, maintenence dose would probably be once a day.

I sprayed 3 sprays of about 1.5% FGHP into my mouth and inhaled it. That was about 20 min ago. I feel kind of woozy and pressure in the left side of my head, and some heaviness throughout my body, and my left eye was watering, but not much in my nose and mouth except a bit of fizzing in my mouth. Bit of heaviness in my lungs from the bubbles (had that before and not concerned), and my digestive system is starting to bubble, which it did the other night - that leads

I'm concerned about the pressure. It won't fizz inside your brain will it?

I have had a concussion, and sometimes get acephalgic migraines on the left side, and I have a chronic sinus infection.

So, is it just from the sinus infection?

Hi- just wanted to comment about a sinus infection I had for over a year and had tried everything...literally. I put a few drops of 35% food grade HP & distilled water in one of those humidifiers that make the mist, and would breathe in through nasal and mouth- and within 3 days I was finally cured after suffering for a year.

I caught a sinus infection (stuffy nose was the only symptom) when my husband was in the hospital and so I couldn't visit him. A family friend reminded me of H2o2 that he's been taking for years so I used the recommended dose in the book "the One minute Cure" by Madison Cavanaugh:

Take 35% food-grade H2o2 and dilute it to 3% (one oz of food-grade 35% H2o2 + 11 oz of distilled water = 3% of Food Grade H2o2). Then put the 3% in a spray bottle. Spray into your nose and mouth every 2 hours and when spraying into the mouth breathe in deeply.

My sinus infection and all related symptoms were gone in 48 hours.

I heard that adding some salt to this hydrogen peroxide solution for sinus infections relieves the stinging. And it does.

I am so glad to find this site. I tried 1 Tbsp. hydrogen Peroxide to 1 ounce water. Q-tip application to each ear and nasal passages (separate q-tips for each of course). That felt a bit better, so I followed that with a few drops in each nostril and tilted head back for 10 seconds. There was clearing. Not much tingling. Followed all this with 2 good gargles. I feel better and can breathe. I think I'll do this morning and night and see how it goes. Thanks again.

I had a terrible sinus infection in the left side of my face. No mucus but pain up into my nose, down into my jawbone, teeth and neck. Couldn't sleep on that side or the pain would flare up for hours. I use hydrogen peroxide for a lot so I put it in water in the neti pot tonight ( couple of tablespoons?) Pain gone. Slept on that side all night with. No problems. Hardly any tenderness in face. Plan on doing this concoction for the next few days, few times a day. Eureka! Magic cure. Put some down in ears on qtip after reading this... mucus I didn't even know I had back of throat loosened up ( allergies).

We have a friend who went into the doctors recently and passed away. She went in for an infection in the jaw, was diagnosed with COVID, and put on COVID protocols. She probably passed away due to COVID protocols.

This home remedy works. I use a 3 step process with 8oz distilled water, 1/2 tsp 3% Hydrogen peroxide, 1/2 tbs salt good for saline.

1) Drops in ears, lay down and keep dropping till you can fill your ear best as possible around 10min,

2) lay down and lay head back and with dropper fill sinus area under eyes with 2.5 mL and hold for 10s or as long as possible,

3) Neti pot but stop after initial stream out other nostril holding head to side gently roll head and also try a slow spin to get solution around perimeter of cavity then blow out. Stay strong and god bless.
