I use half 3% hydrogen peroxide and half water via nebulizer and mask, when I feel a cold or sinus infection coming on, or if I have an ear ache, which can often lead to a cold, or vice versa.
The technique I use is to breath shallow through the mouth for half the time, and shallow through the nose the other half. Now it can be irritating to the nose, so just cut back on that if need be. And every now and then take normal deep breaths without the nebulizer. But inhale the nebulizer mist for a total of five minutes. Do this three to four times a day until the symptoms subside, for me this often occured after the first day.
I don't recommend taking deep breaths of the nebulized hydrogen peroxide, as it can be very irritating and cause bronchospasm, so asthmatics, try this remedy at your own risk. You must be well hydrated and have a good cough mechanism to do this remedy, because the bronchial mucosa will swell with phlegm, and you need to have a good cough mechanism. If your cough if weak, or if you're asthmatic, perhaps you can limit yourself to only inhaling lightly only through the nose and focus on the sinuses.
You may cough up a lot of phlegm, and if the sinuses are involved, mucus may literally start pouring out of you. The phlegm may be foamy in appearance, which shows the action of the hydrogen peroxide.
I first tried this about seven years ago, used it for maybe four cold and flu seasons, and haven't had a cold or flu since.
Also, at the first sign of an earache, I get in the shower and wash my ears and rinse, then I tilt my head and pour a bit of plain white vinegar in the ear, then I kind of tug the lobe to get the vinegar down in there, then I stand there for a minute, then I rinse the ear, tilting the head the other way to get the water out. Then I do the other ear just the same. I repeat this two or three times. Then I do the whole process two or three times a day, or until the symptoms subside, which is often in a day or two. I used to get ear infections all the time that required antibiotics, but since starting this method eight years ago, I haven't had an earache episode that required antibiotics.
I keep a bottle of white vinegar in the shower, often putting a bit of vinegar in the ears as a prophylactic. White vinegar is also an excellent aftershave if you get bumps and pimples like do, the from splashing it on is exquisite.

After finding the info on inhaling H2O2 (thank you Bill Munro! ) I want to add this to my daily regimen.
My first question may seem stupid but I would rather be sure.
Is it important to inhale on an empty stomach? as with H2O2 ingestion. The thing is when I inhale (have tried only once) Im sure that some 3% H2O2 gets swallowed even tho I spit it out, so could that mean no food in the stomach would be best?
The 3% H2O2 really fizzes in my mouth, reacting with my saliva I guess - should I spit this out or swallow it?
Thanking you in advance.
I will post updates as I see results

I just took 2 "whiffs" of the cvs brand 3% HP that was diluted to half strength--I will repeat this at bedtime-
I confess to being a heavy smoker with chronic bronchitis and not maintained on any prescriptives or any inhalors..... Will use garlic/fresh lemon juice or garlic/ACV if I feel the "need" to-when the congestion gets "heavy"/fever, this stuff works to break it up and you will cough it up and out- And am now aware of chronic fatigue type of tiredness and a very deep congestion, esp on the lower on the right side, and wheezing-....... So here I am! And will increase the number of sprays and inhalations and strength of this solution but will continue to use the 3% chain store brand the same as Mr Munro does himself- and I will write back God willing in one week's time to let you know what's up--
But you know what ? I truly EXPECT an improvement-- as others have posted... The HP supplies 0xygen and anybody that ever flushed out an infected area knows how it busts up pus etc and will do the exact same thing on pockets of pure phlegm, mucus plugs etc--and you simply cough all the misery out.

Maggie, I have a question on here about the dilution aspects of the Peroxide. I am informed about Food Grade, 35% and 3%. I've used in Vaporizor and felt fantastic, but it Detoxed me to stomach cramping. Would like to use in Nebulizer! EVERYTHING I read is confusing about "Exact" dilution! Some sites have Mcg, cc, drops, dilate 3% even more. No Homeopathic Doc's here. Read that you used in Nebulizer. What exact amount did you put in cup? Did you mix 3% with distilled water? I appreciate ANY help!

Had some HP kicking around checked out the bottle all it said was pure water no stabilizers present even checked the color of it. When I inhale it I pump it up to about 6 times but I get a slight slight burning at the back of my throat nothing painful but just wondering if this is normal?? Thanks

There's a rumor going around on a few other websites that Bill Munro, creator of the H202 inhalation method, has Alzheimer's. In fact, a couple days ago we posted a feedback from Carolyn on this subject. Well, we just received a telephone call from Bill asking us to please remove Carolyn's post as he does not have Alzheimer's! We did.
Bill told us that there is one man posting nasty things about him on various websites after he called Bill 3 times to harass him with question after question. He apparently told Bill that he should never have posted the H202 inhalation cure on the net because Bill is not a doctor.
Bill admits that he doesn't have a great memory for names, but for sure he doesn't have Alzheimer's.
We love you, Bill!

For the posts about colds/flu working, I have not experienced anything positive from this. I did the emptying out of the nasal spray inhalation method. As soon as I started to feel the throat itching and the nose getting stuffy, I started. First day I did it four times with around four to five sprays each time. All that happened with myself is that I got more sick as you would expect with a cold. The only difference was the my lungs are achy now and I had the nastiest taste in my mouth. Just to see if there has been any benefit, I continued in the morning (after having a fever all night). Still no change. The only thing that has help thus far has been the cold medicine I finally taken. Wish I could say different, but so far, the cold seems to be running a normal course with no benefit of peroxide inhalation.

Hydrogen peroxide inhalation
I tried Mr. Munro's technique after 6 days of chest and head congestion. I don't get sick very often, I do smoke regularly and when I do get sick it almost always goes to my chest because of the smoking I am sure. The H2O2 inhalation was a last ditch effort to clear up the longest flu-like sickness I have ever had! Fortunately, I do feel much better after only one day. I am not completely "healed", but my lungs can breath deeper, and I can cough up what was so thick in the lungs before. I am going to continue to use the technique for a few more days and see what happens. I must admit, I am not doing the same amount that Mr. Munro suggests, but I am inhaling the 3% stuff from the drugstore and about 4 inhales each time, about 4 times yesterday and twice already this morning (been up for about 4 hours). Still coughing, but doesn't hurt and stuff just comes right out! Thanks for the help and I am so greatful for old farmboys like Mr. Munro!

I'm a diabetic on oral medications including high blood pressure. My glucose levels would not drop below 300 a year ago despite fasting. I started with a maintanance dose of 3 drops/8 oz distilled water x3 a day. 2 hours after my third dose, AND after eating a high glucose meal, my glucose level was at 90 exact.
I repeated everything exactly on day two in order to see if this was an anomoly... my glucose level dropped to 84.
And on the third day yet again, down to 76... I had to increase my carb intake between the major meals. This brought up my glucose level to around 90. Add exercise and my A1c was 6.8, my energy level is great, my glucose remains under control. I do not see an end to the diabetes though, short of exercise and continued weight drop.

Hydrogen Peroxide for type 1 diabetes???
I would like to know if any of the people posting about their experiences using HP with their diabetes were type 1 diabetes. I would like to know if it would work same way at lowering insulin needs with juvenile onset diabetes. That doesn't mean the person is a child but that they developed it as a child or teen.
Does anyone know why the HP works??? What's going on inside that is causing the blood sugar lowering effect?
I would really like to try this but am a Type 1 diabetic. If anyone knows will you please post your knowledge about this.
Thank you so much,

I am an avid believer in HP however, I am not completely clear on how to always use it. For example, the 85 year old man who uses a uses a nasal spray pump to cure his prostate cancer etc - I do not even know what a nasal spray pump is, where you can get it and HOW to use it. That should be explained. Also, I read where Ted suggested you can drink it but it has to be a certain percentage and strength BUT what happens MOST on this site is that there are clear instructions often missing and where to get the devise or product from. Just print the exact name and a web site or email address or telephone number. By doing that you simply making a suggestion your not giving advise.

Well Chris, usually mucous is clear but when you get an infection it turns yellow and then green. The sore throat probably was an indication at the onset of an infection hence the change in mucous color. The hydrogen peroxide can help clear up the infection so you might want to continue.

Where to Find Nasal Pumps
Posted by Ron (Great Falls, Mt) on 11/04/2010
People that are using the nasal pump method - I would suggest to ask your doctor (or pharmacist) for a 'spacer' this is a plastic cylinder that one typically attaches a portable inhaler to. But for this purpose, you would spray the mist into the cylinder, then inhale the mist. The whole idea being that with the spacer, more of the mist will travel down into your lungs, rather than collect at the back of your throat. In Lieu of using a spacer, you could hold the sprayer *away* from your face and pump a few times into the open air, and then breath in (through your mouth) from the cloud-mist that you just sprayed. Just a thought. I've had many a nurse or technician say (for using an inhaler) that you *are not* supposed to put it directly in your mouth, exactly because the medicine ends up coating the back of your throat, instead of going into your lungs where it is intended.
Steaming Vs Inhalation

Hello Sumesh! I've been inhaling H2O2 per Bill's instructions for two months now and am pain free. I had the same reaction (sore throat and hoarse voice) for a little while but it all went away in the first couple of weeks. Don't give up!
Steaming Vs Inhalation
Posted by Michael (Honolulu, Hi) on 09/22/2009
Since a ultrasonic nebulizer simply vibrates the H2O2 solution into a mist, it will work. A machine that creates heat will affect the solution. My thoughts on this venture lead toward efficiency and practicality. The pump sprayer is fast, portable, and it works just fine. A ultrasonic nebulizer would be just a fancy and expensive way of achieving the same result.

Well it's been almost two full weeks since I began H2O2 inhalation therapy. I have been breathing easier, especially in the evenings while sleeping. Some aches & pains from old injuries have subsided a bit. I am a one pack a day smoker. No side effects at all from the inhalations. 5-6 times a day, 5 or 6 pumps each. I am occasionally cough up some phlem and attribute it to some cleansing of my lungs. No problems at all. Seem to be more alert too, especially in the mornings upon waking.

Hello I am a 39 yo female with Addison's Disease & Chronic Fatigue & Fibromyalgia, I started doing the 3% hydrogen peroxide in a nose spray bottle 6 drops in back of my throat every 4 hours for fatigue & muscle spasms. It did help me get more energy however I started noticing after 3 days of using that I was getting bad acid reflux, painful tightness of the throat, severe dizziness, nausea, abdominal bloating, hypertension, gas, and the scariest of all as soon as I would inhale the Hydrogen Peroxide my fingers would swell up and turn shiny red/blue & they would get numb & tingly. It happened every time. That was enough to make me stop. 3 days after I quit inhaling the symptoms continued to plague me except I had no finger swelling. The acid reflux & dizziness has been the worse. Today is 5th day and I do feel better & symptoms have subsided. I used the 3% peroxide to clean my face today and within a hour my face looked like there were burns on it? Very red & it looks burned. Does this mean I am allergic to this stuff? I have been battling candida yeast when I started taking it too. I do not understand all these symptoms while on this stuff. It was the most awful experience I have ever had. I was so dizzy I couldn't function. I threw up mucus because acid reflux was so bad. I didn't know if I was sensitive to it because of my addison's or was it a reaction to the yeast or what. Because I did like the energy when I used it. Could you please tell me what you think happened? Thank you

I have used HP as a mouth spray, bath, footbath, gargle, sinus flush and internally. I have benefited from all at times. I lean toward the baths,gargle and internal methods as I get the best result that way. You might try a bath as it has also given me a lot of energy for at least 24 hours following. You may need to stay in 45 -60 minutes. 200 mls of 35% foodgrade per bath. HP I have recently overcome a "bug' that i could not shake any other way.
My method: HP food grade 25 drops (2.5 ml ) into 1 liter de-mineralised water. Drink half of this 45 minutes either side of food. Drink it all at once. Once a day. If you get a reaction it may be temporary but if it persists you may be better to take a break for a day or two then try again. Alternately reduce the strength and/or the volume you drink.You could also try taking a toxin absorber such as bentonite clay to mop up any die off the HP is doing.
See my post from 09/06/2008
I have also had a hangover reaction to HP when I first started using it but I do not experience this now. Personally I find 3% strength too strong even in a spray. I get good results with just .5% for gargle and sinus. The strength described above is only .25% and easy to take. Good Luck

I have emphysema, caused by smoking for many, many years. To all who are still smoking (why?) I can recommend Tabex tablets. Google tabextablets - $30AUD. They made it unbelievably easy, so I told my son. He also quit with no problems.
Having tried just about every other method, I was amazed at how easy it was. What made me cross was finding out they have been available for 40 years, and I never heard of them!
They are made in Bulgaria, and I definitely have no connection to them. Just wanted to pass on the info.

i hope people know, who are reading these posts, 12 years later (2023) that since the popularity of that "Amaz**" amazing store, even in the USA, we can purchase 12% food grade hydrogen peroxide as easy as picking up our cell phones. sure its a little more expensive than the dollar store, but why take the chance?? Food grade is EASY to order on line and probably safer than topical. And while im advocating for quality of product... while nose spray is good, perhaps, for inhalation; a hand-held NEBULIZER produces much finer (smaller) particles which is much easier to absorb in the lungs. Less than $50 at that "amazing" store. You could "breath" in a 1/2 teaspoon of water w/ H2O2 in one quick inhale (followed by coughing like you just got pool water in your lungs! YUCK! Or you could gently inhale that same 1/2 teaspoon of water w/ H2O2 over say 10 minutes... no coughing. easy and gently absorbed.
