More on Hydrogen Peroxide for the Cold and Flu

Dr. Mercola's Comments:


Last November I initially posted this information, and then pulled it after it was on the site for a few hours as I had reason to believe the source was flawed. I replaced the article with another related one.

I recently re-postedthis article which you can review for the original peroxide article.

Others have written in to share their positive experiences with this inexpensive and practical solution for a common problem that many face.

However, I continue to maintain that it Is far more effective to be proactive and not get colds in the first place. It seems the major reasons why one gets them to begin with are:

  • Going off the eating plan
  • Stress
  • Not enough sleep
  • Any combination of the above

So clearly the first approach is be careful and avoid food choices that will sabotage your health. If you are stressed please consider EFT, which is an amazingly effective tool to address the foundational and core reasons as to how the stress is impairing your immune system.

If, for whatever reason, you have come down with a cold my personal recommendation would be to use zinc lozenges. I have been using zinc in my practice for over 15 years, far before it was popular.

When using zinc lozenges it is important to recognize that they need to be sucked on, NOT swallowed, and smaller doses more frequently seem to work better. I usually advise patients to suck on a quarter lozenge every 30 minutes. If started early, this approach seems to work well for the clear majority of patients.

Two cautions should be heeded though; if the lozenges make one nauseous they should be stopped immediately as that is a sign of zinc toxicity. If you follow this guideline and listen to your body you will avoid the copper imbalance referenced in the study.

I too was one of the ones that caught your original post on the subject of peroxide in the ears and then went back to review it only to find it had been changed. I am so glad that you have restored the information.

Now for my story that happened within two days after I read your original letter.

I went to the ENT specialist all the time and they were always giving me hearing tests. The last test the nurse remarked that my hearing was more diminished then ever because the Eustachian tube was so blocked. They wanted to give me the usual antibiotics and other stuff (which never worked anyway) and I just took the scripts like a good girl and went my way -- rather disgusted with the whole scenario.

I came home and applied the peroxide in a laying down position. I didn't hear any bubbling -- that's because the tube was just about totally blocked and the liquid wasn't even going down into the right place.

After a few minutes I felt a little trickle and heard a little something that sounded like bubbling. On the next application...the process didn't take so many minutes but on the third application the liquid went swooshing down into my ear the minute I squeezed the drops in.

I shook a quick shake when the peroxide hit the bottom of the canal. I heard a lot of bubbling. That day I started to hear again especially in my right ear and the pressure in my head left. I felt balanced as if the Eustachian tube had opened. I heard things in stereo instead of just from my left ear. I was ecstatic!

I thank you from the bottom of my heart.

I have lots of bottles of peroxide in my medicine cabinet now. What a wonderful natural remedy.

It's interesting that the experts at the specialist office failed to see the problem or offer correcting solutions. They even wanted me to take powerful drugs that work systemically when all I really needed was something you might call topical or local.

I hope that people will give serious consideration to this remedy, because it really, really works.

Best wishes

My Wife and Daughter and I have been using Hydrogen Peroxide for colds for three years. The majority of times it aborts the cold. The few other instances, it substantially reduced the length and severity of the symptoms. We don't get the flu, so can't comment. We haven't used antibiotics in years.

Thanks so much for your news letter, it's great!

I have used peroxide mixed with some fresh garlic juice in one of my children's ears. My six year old son recently had ear pain that got so bad the he was screaming and crying. Shortly after putting a few drops of the peroxide and garlic in his ears he began to get some relief and could sleep! Then my eight year-old daughter popped up with ear pain, and she instantly got relief from the drops.

This is a very old remedy, my mother told me that, it was used in British India with great success and caused quite a racket. To debunk it, the mainstream came up with a scare tactic claiming the peroxide would drive the infection into the brain.

Imagine! Well it worked and people got scared and eventually stopped using it.

I can vouch for Wendy Fyfe's experience mentioned on your web page. For the last 2 years, my family and I have been using the commonly available 3% Hydrogen peroxide to cure the common cold and flu.

Nothing is as effective!

Every time we traveled to India we came down with very painful strep throat, gargling with Hydrogen peroxide frequently always cured strep throat in a matter of hours, however, when used in the ears it's even a bigger miracle and simply prevented these strep throat episodes!

Its great for ear infections particularly in children even if the ear is slightly perforated.

It is also the best earwax cleaner, and is safe to boot, unlike less effective petroleum based, plus god knows what else, over the counter and prescription based remedies.

The only things to watch out are:

  • It tastes horrible but its easy to get used to you can dilute it with water at first if you like however never drink it hence gargling is not recommended for children;
  • Don't get it in your eyes; and
  • Don't overdo the gargling if you have mercury amalgams.

Speaking form personal experience one should never travel without it (H2O2). A convenient way to dispense it is via a small dropper bottle this save all the fuss and muss of a dropper.

Vitamin C is also useful as explained by Dr. Linus Pauling in his last interview:

"There is no doubt now that vitamin C in large doses has value against the common cold. My recommendation is not 1 gram a day, or 2 grams a day of vitamin C but at the first sign of a cold, take a gram of vitamin C or 2 grams and then an hour later, if the symptoms still exist - if you're still sneezing, or your nose is running or feel shivery, take another 1 or 2 grams of vitamin C. Keep doing that until you forget because the symptoms have gone away and this will stop a cold in almost every person who follows the regimen." Full interview is at:

Dear Dr. Mercola

I read about your peroxide therapy via ears for colds, flu, etc. and have tried it for about 5 days and am amazed and thrilled. My constant allergy/asthma symptoms of nasal drainage and scratchy sore throat, swollen glands, and low-grade infection-like symptoms have cleared up almost overnight!!!

My doctor has prescribed a shoe-box full of Azmacort, Serevent, Flovent, Guiatussin, Albuterol, Claritin (a real waste of time and money), Singulair, Flumadine, Prednisone, Guiafed, and Rhinocort. Really nothing was working except the prednisone, and not very well at that. Plus I am concerned about taking prednisone with my osteopenia.

I look forward to my emancipation celebration by dumping the contents and recycling all of the cardboard and plastic packaging.

Thank you again.

Thanks so much for the peroxide cure. When I read it, I figured it was just one more hoax, but I wrote it down somewhere and promptly forgot about it.

The second time you posted it, I decided it must be worth remembering so I wrote it down again. A couple of days later I came down with the flu. I was at work, and started feeling achey all over, and blowing up buckets of snot, feverish, ect. I was going on vacation to Branson MO for a long weekend and I just knew I was not gonna get to go. I decided to try the peroxide "cure".

I asked our company nurse for some peroxide and a couple of swabs. I went to the bathroom and poured it into each ear in turn and let it bubble a couple of minutes, dumped it out and swabbed out my ears (gently of course). In a few minutes 90% of my symptoms were gone. I could not believe it!!!

I started to feel bad again that nite, so, I did the peroxide again and no more flu!!
Ive told alot of people since then, I wish I had known this years ago, cause I have a cold and the flu every year at least once.

Thanx again Dr. You are one of the few doctors that really has a grip on how medical treatments should be. Also thanx for the cookbook, Im just starting to experiment with some of the recipes.
