Hydrogen Peroxide Inhalation Method Bill Munro.

Bill Munro developed a simple yet powerful method of inhaling 3% hydrogen peroxide to boost oxygenation, support immune health, and fight viral and respiratory conditions. His method has been featured on Earth Clinic since 2004, inspiring thousands of readers worldwide.

How to Prepare the Inhalation Spray

  1. Sanitize a Nasal Spray Bottle: Clean an empty saline spray pump using hot, soapy water. Rinse thoroughly to remove residue.
  2. Fill with Hydrogen Peroxide: Pour in 3% hydrogen peroxide. Food-grade is preferred but not required. Avoid using higher concentrations unless properly diluted.

How to Use the Hydrogen Peroxide Inhalation Method

  • Position the Nozzle: Aim the spray bottle toward the back of your throat. Do not inhale through your nose.
  • Inhale Deeply: While pressing the spray pump, inhale deeply. Use approximately six sprays per inhale.
  • Frequency: Use the inhalation method 4 to 6 times per day. During acute viral infections, apply every 2 hours.
  • Relief Timeline: Many users report symptom relief within 36–48 hours. For chronic infections, use consistently for up to two weeks or longer.
  • Test First: Spray into a spoon first to test spray volume and avoid excessive intake.

Safety Guidelines

  • Use only 3% hydrogen peroxide. Do not inhale higher concentrations without proper dilution.
  • Food-grade hydrogen peroxide is ideal but not necessary. Bill Munro used pharmacy-grade 3% peroxide safely for over two decades.
  • Never ingest undiluted hydrogen peroxide. This method is for mist inhalation only.

Bill Munro

Bill Munro, a retired phone technician, shared his hydrogen peroxide inhalation therapy with Earth Clinic in 2004. His philosophy was simple: oxygen kills viruses and bad bacteria. He credited his good health and recovery from serious illnesses to regular use of this remedy.

"I’ve been inhaling 3% peroxide for over 13 years. When diagnosed with melanoma and prostate cancer, I increased to 7–8 inhalations a day. Four months later, my PSA test came back cancer-free. I now inhale five sprays per session, seven times daily." – Bill Munro

How Long to Use This Remedy?

  • Viral infections: Relief in 2–4 days with consistent use
  • Chronic infections: May require 2–4 weeks of use
  • Cancer support: Bill used the method intensively for 3–4 months

Benefits Reported by Bill Munro

Bill lived to age 90 and attributed his vitality and energy to daily peroxide inhalation. He reported the following health benefits:

  • Better breathing and increased lung capacity
  • Less fatigue and muscle soreness
  • Relief from chronic infections
  • Boosted immune system and mental clarity

Watch: How to Do the Inhalation Method

In this step-by-step video, Deirdre Layne, founder of Earth Clinic, demonstrates Bill Munro’s method. She has used this technique herself for over 20 years:

What Conditions Can This Method Help?

Earth Clinic readers have successfully used hydrogen peroxide inhalation for:

  • Chronic obstructive pulmonary disease (COPD)
  • Colds and flu, including viral respiratory infections
  • Asthma, bronchitis, and chronic cough
  • Herpes virus outbreaks (oral and genital)
  • Prostate and skin cancers (per Bill’s personal experience)
  • Immune system support and energy enhancement

Potential Side Effects and Cautions

Most people tolerate this method well, but a few may experience:

  • Mild throat irritation after initial use
  • Increased mucus production as the body detoxifies
  • Dizziness or lightheadedness may occur if it is inhaled too quickly

Important: Always use 3% hydrogen peroxide only. Discontinue use if you experience discomfort or unusual symptoms, and consult a healthcare provider if necessary.

Scientific Perspective

While research on hydrogen peroxide inhalation is limited, studies confirm its broad antimicrobial action. Peroxide generates oxygen, which may inhibit anaerobic pathogens and support cellular respiration. However, more clinical trials are needed to validate its therapeutic effects via inhalation.

Final Thoughts

Bill Munro’s hydrogen peroxide inhalation method remains one of Earth Clinic’s most talked-about natural remedies. Thousands have used it to improve breathing, fight viruses, and support their overall wellness—often when other treatments fell short.

If you're exploring natural, oxygen-based therapies, this simple at-home method may offer meaningful relief—remember to follow all safety guidelines and start slowly.

HI U ROZ,,,,,, ORH here and I have had cancer three times in my life and treated it differently as I learned. My doctors love me but they don't like me. That is the way with most marriages. All love their spouse, they just don't like them. I like my TRACTOR DRIVER and we have been married for almost 62 years. I think she likes me. I do tests that normal folks don't do, so I catch cancer in stage I or stage II. Cancer needs your body to be acid and low on oxygen. I spent 45 minutes on the phone with Bill before he died and he is one of the good guys. Your immune system handles your problems until you old as dirt. At 84, I still do a garden because store stuff is garbage. We took tomatoes and peppers to church today to give to the congregation. My preacher keeps telling me that I can't work my way into heaven. I am taking no chances. My PSA test is telling me that I have prostate cancer, but I refuse to get a biopsy because all that does is spread the cancer all over your body. I inhale 1 and 1/2 % hydrogen peroxide every morning to open my nasal passages. I am doing the dog dewormer thing to address my prostate cancer. None of this amounts to a hill of beans compared to the evil that is consuming the world. I thank you for giving me a chance to get my message out.

Just wanted to add: I contacted Bill by phone around 2004, when he was 80 years old. He had already been inhaling H2O2 since he was 70 years old, when he first contracted skin melanoma, which was agressive. The doctor told him to quickly go to the clinic to start chemo, but he told the doctor no, that he was going to inhale hydrogen peroxide. The doctor told him he's crazy, that he would kill himself. Bill went off and cured himself fairly quickly and went back to the doctor, who was shocked. The doctor did follow-ups over the 10 years and Bill, and his wife, were never sick. Finally, the doctor was reassured and the doctor started inhaling H2O2 himself.

In response to an old post in the asthma section inquiring if anyone had used peroxide in a nebulier:

Yes, I tried nebulizing 3% hydrogen peroxide because I had a cough that would not go away (no help from doctors), and it was getting worse by the month. I tried many other things via nebulizer but nothing worked until I used OTC regular hydrogen peroxide in an Omron Micro Air nebulizer (palm sized, silent, battery operated).

I took a deep breath and spent the next two minutes trying to catch my breath. I realized caution was in need so took more shallow breaths and finally deeper breaths. That cough went away and never came back! I now use 3% food grade hydrogen peroxide available from Swanson Vitamins.

I'd like to ad my 2 cents on the Hydrogen Peroxide Inhalation methode from the late Bill Munro.

My father already had a history from asthma since he was 6 years old. Back in the old days young children would be sent to live by the sea for a few months in order to heal. He smoked, unfortunaltly, 'till the age of 57. Stopped, because he needed heart-surgery due to being diabetic since he was 16 years old. When he became older his lung problems reappeared again. With a bad case of double pneumonia in 2003 that nealry killed him.

I kind of stumbled across Earth clinic a few years later and learned about Bill Munro's Hydrogen Peroxide Inhalation. (Among so many other life-saving tips and knowledge.) Since then I was able to stop every bout of bronchitis he had before it could develop into pneumonia. Which would have killed him at his age. By using Hydrogen Peroxide in a nebuliser. Of course Food Grade 3% with the same amount of distilled water.

He died last May, 88 years old. And was regarded a walking medical wonder by doctors because he got that old in spite of his many health scares. Just died in his favorite chair because his heart simply stopped beating. I saved him many times with the healp of Earth Clinic when doctors had given up upon him. Thank you all for your contributions here.

Total H202 Routine:

I have used the H202 inhalation method for years and it has been very effective for colds or other sinus infections. Once I notice a cold coming on at Day 1, I do the Munro throat spray routine at 3%, for about 3x's. Then I move on to a mix of 1.5% H202 in the nasal sprayer (3% is too much for your nasal linings), then I do a routine of H202 in my ears for 4 min each ear then dry them out with kleenex & cotton swabs and finally after all this drains into your mouth I gargle for a minute with H202.

IF I do this on Day 1 I have never had to go to Day 2 of this routine - never in 10 years of use. This is why people go to Ear, Nose & Throat doctors - these are ALL inter-related. You need to fix them all. Hope this helps.

Aloha from Hawaii,

I have been using Hydrogen Peroxide 3% as an inhalation treatment when fighting cold/flu symptoms of the nasal passages or lungs for decades.

I use it every time I get any form of runny/stuffy nose or any itching lungs/coughing. It really is amazing how fast it works. I clear my nasal passages out with 2-3 quick sprays up each nostril (and it hurts!! ) this is not for wimps as it does get really sharply painful for a few seconds and sometimes feels like my head is going to blow off!! My sweet, lovely, little wife does it too, so unless you are truly a wimp...you'll be fine. LOL

However, using this method along with sudafed to open passages if blocked (so the h2o2 can get up there) I have not had a sinus infection or bronchitis for over 20 years. I used to get bronchitis and sinusitis every year when I caught cold. I started doing H2O2 mist instinctively because it just made sense to me that it would destroy the viruses and bacteria that were causing the issue in the first place. I had read a book called: Hydrogen Peroxide: Medical Miracle and felt that if it could perform so well in all those medical studies without harming any of the patients...it would be good for my nose and lungs.

So, nasal mister with 3% hydrogen peroxide in it and use it any time there is a symptom of any kind. If I end up with a bad cold as recently happened because I didn't get up at night and do this, I just do it every few hours daily until the issue (nasal or lung) is gone. I also use ozonated water machine to make quarts of ozone water to drink 3-4 times daily and eat very little food when fighting illness of any kind.

As a retired RN I can tell you right now that if everyone used this method to fight disease we would all be far healthier and better off.

Blessings and Aloha.

I tried Hydrogen Peroxide a couple of times 2 years ago when I was having severe issues that the doctors could not help. 8 months of coughing up blood and having to sit up in bed due to what sounded exactly like a death crackle if I lay down at even a 45 degree angle! I felt like my chest was made of glass. CT scan showed no cancer. O2 levels were not too bad at that time though they would drop to 80 at night. During waking hours rarely got below 92. Still struggled to breathe though.

In desperation, I used Hydrogen Peroxide in nebulizer diluted (regular 3 percent over the counter from CVS). I only did this a few times over 2-3 days and when I went to the pulmonary specialist for a checkup my o2 level that day read 100 percent. I HAD NEVER seen that and actually it scared me a little so I stopped the peroxide. Things improved for a time until I was put on Arava for Autoimmune issues. Immediately breathing issues. Rheumie seemed unconcerned and even angry that I had adjusted my dose to 1 every 2 days just to breathe for a few days and still be able to walk!!

Long story short, fast forward to Rheumie halving the dose and instructing me to take 1 every other day and persist until side effects cleared up. THEY NEVER did and my breathing got worse and worse. I realize now I probably was getting infections that they were ignoring due to the Arava lowering my immune system. I no longer run fever after a lifetime of severe medical problems so can be quite ill with no fever but doctors only take you serious if your blood work shows really high elevations of Neut/Lymph etc. and mine were only small elevations and my temperature actually would go in the opposite direction. The sicker I get the LOWER it goes. I have seen it at 95 many mornings. And yes Thyroid checked.

Long story short I progressed to being unable to breathe at night. Sleepless nights wondering if I should go to ER. Palpitations(both PVC and PAC) coming about every 3 to 10 beats. Nebulizer meds and even a dose of Racepinephrine at times offered little help. The past month I had gotten so bad I could not walk 10 feet for the weakness and palpitations and shortness of breath. I did not want to go to ER and be put on a Ventilator. I was literally waiting to die at home and struggling to breathe is no fun so I knew I would eventually give in and go to the hospital one of those nights. My o2 levels were now dropping to 80 while still awake which they had never ever done.

I had been afraid to use the Peroxide again due to the unknowns, but now things were critical I felt. I LITERALLY FELT IT WAS die or try it again. THREE days ago I nervously tried putting some peroxide in my nebulizer cup and leaving the mouthpiece off. I would put my mouth over it for a second and breathe it in deeply. I only did this 3 times with the full strength peroxide. Only did it about 3 times both days. WELL LAST NIGHT MY o2 levels did not drop below 91 and mostly hovered at 92 to 94 before falling asleep. THIS MORNING I WOKE UP AND HAD SLEPT THRU THE NIGHT without having to wake up to do a breathing treatment. I did not cough up anything much this a.m. I could take a deep breath and the PVC and PAC were down to maybe 1 or 2 a minute instead of 20-30 a minute!! BUT THE BEAUTY of the side effects was I COULD WALK when I got up today. My RA and PSA seemed greatly improved. I had energy for the first time in 6 months!!!

I am crying now because today is the first day in months that I believe I might be able to see my grandkids for Christmas!! I was not sure I would even still be here by Christmas! I cannot tell you what it feels like to be able to take a deep breath and walk more than a few feet without resting!!!! I am optimistic that I will continue to improve.

THANK ALL OF YOU FOR POSTING or I may have been too afraid of doing more harm. I think I may live now though.

I am now convinced that I have had mold and bacteria in my lungs causing most of these issues and doctors just don't treat these I have long found. The peroxide is killing it off I believe. I take 7 days a month of an antifungal (itraconazole) and my doc kept saying if it was fungs in my lungs the antifungal should take care of it. SHE IS WRONG WRONG WRONG.
