When I tried swishing the peroxide around in my mouth with a bit of water it took down some of the swelling in a wound on the inside of my cheek. It also helped the pain I had with my teeth and gums.

Sodium Laureth Sulfate is a detergent used in 99% of toothpastes. Its on the EPA's list of "Possible Carcinogens" and has been linked to CANKER SORES. Change your toothpaste to a natural one that is FREE of Fluoride and FREE of SODIUM LAURETH SULFATE. While you're at it, check the label of your body wash and shampoo too... SLS's are very dangerous.

They're bad for you and they're bad for the environment (after they do down the drain, they've been linked to infertility in whales).

Please switch from any product that has SLS in it.

I have been taking about 1 ml of 20% food grade hydrogen peroxide since 38 days. It has been a miracle for my post chikungunya aches and pains. It also cleared up the mental fog which I didn't even know I had. I feel fantastic since taking H2O2.

I am 39 years old. No children. I have had polycystic ovarian syndrome since I was 25. With diet and exercise, I have been able to keep the symptoms down to a dull roar.

My last period started on Nov 25th. And it is still going on. Heavy with gushing. This kind of period hasn't happened in years. I have taken blackstrap molasses without any change.

Is this because of the H2O2? The One Minute Miracle book says H2O2 is required for sex hormone synthesis. Is that what is happening in my body? Excessive estrogen production?

What should I do? I would love to continue the H2O2, but not if this kind of period is going to be a regular issue.

Any advice welcome. And thanks in advance.

I know it's been a long time since your post, and I hope you've already eliminated your PCOS, but it sounds like an iodine deficiency to me. Here's what I would recommend to a loved one with the symptoms you describe:

(1) Watch the Dr. Flechas video on YouTube:


(2) Study the subject -- including people's experiences on EarthClinic.com and reviews for Lugol's iodine on Amazon. It's a complex topic, but one that merits however much time it takes to become knowledgeable about it.

(3) If and when you're ready to try it, study the iodine protocol so you get the important accompanying nutrients -- especially organic selenium, magnesium, zinc, and niacin.

(4) Work up to a dose of at least 50 mg. of iodine per day (5 days a week) subject to how severe your healing reaction is. (You can take more days off if you need to do so.)

(5) Be ready for the healing reaction symptoms and don't be scared off by them.

This happened to me as well. I have a lot of genealogical issues as well. It is a detox reaction. I talked to my Naturopath about it and she said yes, this does happen as a result of peroxide or even medical ozone use. I backed off for a bit and started again. My symptoms were horrible. Hope this helps.

Chronic Fatigue Syndrome

Hydrogen Peroxide major turn around then not. I have been rebuilding my health following CFS for many years but in June 07 I had "Influenza A" which really knocked me around. I thought I was recovering ok but the old CFS symptoms re -emerged ie headaches, brain fog, unrefreshing sleep, fibromyalgia, blurred vision, sleeping all the time. In November 07 I found EC and tried H2O2 food grade. At first I tried the inhalation method for a couple of weeks but progress was not really fast enough so I took it internally. Due to my low energy and fogginess I managed to take the upper end dose on the first day (normally people build up to this over a few weeks) ie. 150ml of .50% 1/4 tsp baking soda three times in one day. This is equivalent to 25 drops in 150ml of water three times in a day.

Results: first intake - nothing

Second intake - my vision improved markedly over a ten minute period. It was as though a veil had been lifted from my eyes. Everything was sharper colors were brighter. I also began to feel more energy. (Since the flu my eyes have detiorated, I had to get a new prescription for my specs. And they had to make them 3 times because my vision varied so much from day to day. ) Third intake - nothing noticeable.

The following day I woke with a headache and fogginess and figured I was in for a detox reaction. This lasted until around 2pm and from then on I felt fantastic. I mean I felt exceptionally good. I felt like hugging strangers in the shopping mall. Giving money away, imagine no possessions and so on. It was exuberance, lightness, abundant energy. It lasted about 3-4 weeks. During this time I did some maintenance doses on a lower scale.

Results not: Anyway I have since had a garden variety bug and many of the symptoms have returned but to a lesser degree except for one debilitating condition that is worsening. When I eat - anything - I get a hangover and overwhelming fatigue for about 90mins. I have to sleep it off. I have tried various alternatives ie ACV & BS but to no avail. Does any one have any ideas what might cause this? I can't go out or for very long because if I have to eat I have to sleep.

I do not have any apparent digestive problems but it is probably connected in some way.

Thanks to the writer from Australia who described peroxide "hang over effect." If after eating you notice a higher heart rate, strong fatigue, sweating and sleepiness, this is probably due to peroxide hang over. Like coffee or alcohol, peroxide will build up in daily use.

I had noticed these effects with daily footbaths/baths/shower use after 5 weeks, and into my sixth week, I was into peroxide hang over. I stopped using peroxide for the time being and its been about 5 days of after effect.

So anyone with chronic fatigue or post viral fatigue will see a return of symptoms after several weeks of peroxide use. Don't worry about losing ground, the hang over effect goes away after a few days, and the peroxide being worked through the system will continue to work. If you wish to continue, make certain to give it a bit of a rest and not try a miracle cure in the shortest time possible. It will be disappointing for chronic fatigue sufferers to hear this, but having serious peroxide hang over effect will almost certainly not help.

Its best to determine a maintenance dose once a buildup of peroxide occurs, and remember to drink lots of herbal tea or water afterwards. It would be interesting for the medical community to study peroxide hang over as it is exactly similar to chronic fatigue.

To Fransix from Toronto. Thanks to your comment, I finally think I know why I feel so bad using the hydrogen peroxide therapy. (you can read my question if you scroll up to the candida section. ) But I feel alot better now knowing that there is a reason to why I am starting to feel bad. Have any more info on the peroxide hangover? I'd like to read more on how to procede with the therapy. Thank you, Tina

Hi, I had the same symptoms after eating (i.e. heart pounding, needing to sleep) due to CF. For me D-ribose helped a lot as it gave my body more energy for digestion. It helped my energy levels generally too. (PQQ which stimulates the body to produce more mitochondria also seems to help but it's a more gradual improvement over time.)

Chronic Infection

Hydrogen Peroxide has been a miracle for me!

I have had a chronic infection of some sort for the last 2 years and four months, non-stop; mostly sinuses, but also bladder and ears. I am in my 60s, female, white, at a perfect weight, but have Hashimoto's (autoimmune) and candida due to heavy metals.

My infection seemed to start with a tooth that my dentist missed (for any tooth pain that won't go away, find a dentist who has a 3D cone Xray machine), and then I had cellulitis in my eye from being splashed in a hot tub.

My face was swollen so badly my boss did not recognize me, then it was beet red and hot to the touch. The hospital doc thought it was MRSA, so took antibiotics, had a CT scan with no obvious blockage and thought it was all over, but it continued in some other capacity – ear infection for 3 months, lost that bad tooth, then a root canal, followed by a bladder infection.

I ended up with severe gum, jaw pain on one side that went on for months. I had ozone injections for a month, which helped. Once the ear infection cleared, I started back in the hyperbaric chamber with an oxygen mask once a week. Took plenty of antibiotics plus colloidal silver (CS) and hydrogen peroxide (HP). By then I was having gastritis or GERD. Again, another sinus infection flared, followed by two more root canals.

After that, I began reading about a similar experience in biotoxinjourney.com, where the author mentioned pain in the tooth socket, sinus problems, etc, just what I had. He talked about biofilms and used a BEG Spray, (Bacitracin, EDTA and Gentamycin, an antibiotic, a chelator and an antifungal). I got that from my doc at a compounding pharmacy and made some improvement with that, but the infection still seemed to be everywhere.

Once again, bladder issues as infection seemed to travel. After taking 5-6 antibiotics that year, sometimes 17 TBSPs of CS a day, and a low dose of HP (I got up to 25 drops), I still had pain and infection. After being on the BEG spray for 6 months, I started seeing yellow drainage, so I knew that was the source.

Still desperate to get stable, I started nebulizing HP with my small nebulizer and a cool mist humidifier. That seemed to help even more than when I was taking it internally. The salt in the HP ruined my cool mist unit, so I just use the nebulizer about 8-10 x a day.

You can nebulize every hour according to Dr. Shallenberger and it goes throughout your entire body, just like an antibiotic, but with no side effects.

I used about 7-10 sprays to start, then built up to fifteen sprays in a plastic bottle or around 1/8 – ¼ of a teaspoon with a 9% vial of the same amount of saline, and had been doing this for about a month when I had another ozone and laser treatment on the jaw area.

I had infection drain into the cheek area so much that there was a lump on the side of my face. For that, I placed a poultice of Clay, charcoal and castor oil each night with a heating pad over it, for 5 days, then after that, placed small makeup pads inside my mouth at night with clay and charcoal, just about my teeth.

It provided tremendous relief, soaking up that draining infection. That seems to have been a turning point. I have now been nebulizing HP for about 8 months and have only had 2 episodes of tooth/jaw pain. I can nebulize about 4-5 times a day and keep it under control. I have had no issues nebulizing HP that long. I still use the BEG spray (a year now) and it is still draining color. I have more energy and the fungus on my toes is gone for the first time in 12 years. I also use a rife machine for “lymph problems” and it has helped my body get rid of toxins. I've had sinus infections all of my life and I think it is just layer after layer of infection that built up with biofilms, but my body is now stable and I can just deal with the sinuses. I do believe the BEG spray is chelating metals, fungus and infection from my sinuses, but the HP has been critical. I had been praying fervently for some way to recover and mostly what came to mind was, “Ask, Seek and Knock, ” so I searched and prayed God would lead me to what would work for me! And He did!

Alright, so I read about H2O2 therapy and decided to get some 35% food grade HP for general detox. My wife agreed to try it as well. Not one for small starts, I gave her and myself the full 25 drops diluted in water on an empty stomach. Very unpleasant for me, but much worse for her. She threw up after about 20 minutes and said it was the worst vomiting episode she had ever experienced. She then when back to bed and slept the rest of morning and was wiped out most of the day. Next day, I get her to take 5 drops in water and that proves stable for her. Again 5 drops 2x more that day. Day three, while we are out for breakfast she tells me that her feet are so hot they are tingling and are purple. Now I must explain why this is significant. My wife has suffered from very poor circulation since early teen years. This has presented in ice cold hand and feet at rest, even in summer. Winter nights will find her under many layers of bedding, with sweats, space heater running and sometimes a sock cap. Near the point of comedy, if it were not so miserable for her. I have tried her on cayenne and L-Arginine, which helped some, but was not a cure.

So three days after taking H2O2 for the first time, she found herself with hands and feet that were burning up and purplish red from some new found circulation. This condition proved painful and she started holding her hands under cold water occasionally and only wearing flip-flops as shoes were unbearable. This overheated condtion lasted around three weeks and then subsided. Now another three weeks have passed and her circulation appears to be very normal. She is now wearing light bed clothing and will kick the covers off in the night, which is very different. She says that her circulation problems appear to be over. She is no longer taking the peroxide as it was just too upsetting on her stomach overall.

A sidenote, she has had significant constipation issues her whole life, and the weeks she was taking the HP, she became very regular, sometime having a BM 3x per day. Now that she has stopped the HP, she has started to become irregular again. Time will tell if the HP has cured her circulation issues, especially this winter. Will try to follow up this winter regarding. For me, it has been good. I have no major health issues, just overweight, which has a cure, but it is not HP unfortunately. (smile) I was extremely tired after taking HP the first few day and slept a lot. Now I am taking 25 drops once every other day. It is quite an energy booster and my allergies have been down significantly. Very impressed, and will continue to use it. Ted's comment that lecithin caps will ease the nausea has worked well for me, and I may get some benefit from the lecithin on weight loss as well.

I have struggled with candida for years that had become immune. I finally found a solution which a liquid treatment soaked into sugar. It has worked wonders for me. Why is this significant for you? It is because that the H2O2 soaked into sugar no longer causes me any nausea. I may be suffering a peroxide hangover and will use food grade turpentine, or GSE for a few weeks and take a break from the peroxide.

Are you still following this protocol? I'm wondering if it's still beneficial to you, any side effects or issues arising? I'd love to hear about your ongoing experience if possible! Thank you!!!

Hydrogen Peroxide has worked great for my acne and periodic cold sores. Once or twice a day I swab my face with it after washing. I also rinse with it after brushing. I have not had a blemish or cold sore since!

I too have had cold sores all my life and am 50 yrs old now. I had a sore in the inside of my nose for 3 days , first I dapped peroxide.3% on the outside and the inside where I felt it sore and there was no change into the 3rd day. On the 3rd day I inhaled 3 or 4 puffs of a mix of half water and half .3% peroxide cheap kind, from a 2 oz spray bottle that you can buy for .50 in the toothpaste aisle where they have travel size items, and 2 hours later all the nose pain was GONE and no longer had a sore in my nose , it vanished. I also used Apple cider Vinegar. I take the pinch or 1/4th tsp of Baking Soda and 2 TBLS of APPLE CIDER VINEGAR in 4 oz of COLD WATER and it has lowered my heart rate from 117 to 72.This has also lowered my BLOOD PRESSURE from to 112/60 I feel full of energy and I do this before I eat first thing in the morning and last thing at night. I sometimes take it at NOON for a pick me up. I no longer have acid reflux/ GERD. I sleep and breathe better as I have sleep apnea.

... I have tried plenty of the remedies on this site and they have all worked. H202 on a cold sore healed within 48 hours just dipped a q tip in 3%h2o2 and held on for 5 min 4 times a day. Baking Soda and water to gargle for extremely sore throat with swollen glands gone in 1 day. I gargled for about 10 minutes with my head tilted back 3 times thru out the day. Wow is all I can say about this one. thank you all so much this site is a blessing.

My vanity for white teeth found me reaching for the peroxide 16 years ago. A side affect was that I was no longer experiencing cold sores (approx 6 a year). My regime was brushing teeth, gums, and tongue with peroxide a couple times a week. When I forgot to do this, the tingling sensation of an outbreak reminded me to do the peroxide treatment and no cold sore surfaced. There have been a few times that I was out of peroxide and got the cold sore but it was gone within 2 days of getting peroxide and the sore was very mild. Apply directly in addition to brushing the entire mouth. I've had two cold sores in the last 15 years. The one during my divorce and the other after getting unjustly fired from my job. Both were mild attacks.

Hydrogen Peroxide for Colds and Flu

Put 3% H2O2 in a nasal sprayer bottle and use it to inhale into the lungs (not the nose!! ) or you could use a small glass spray bottle. Inhale in for about 3-5 short breaths while spraying back into the throat each time. I just swallow the residual that is left in my mouth. I inhale h2o2 almost every day, and if for some bizarre reason I feel something come on, I inhale it 3-4 times a day. I also keep it in the refrigerator so it doesn't lose its strength over time. Have not been sick once...especially with the crazy Cvd virus these days.

Colds and Flu

I have been an avid Earthclinic fan for the past 2-3 years and thank God regularly for this website.

One of the most exciting cures for me has been Hydrogen Peroxide 3% for Colds and Flu's. For about two years now I have been dropping 3-4 droplets into my family's ears and letting sit for about 2 minutes each side before draining. If done when the symptoms begin it has usually meant all symptoms are completely gone in about 24 hours. It has been such a relief to be able to nip colds in the bud and get back to normal life relatively quickly.

This last couple of weeks a new test came along for my family with a nasty respiratory virus which has run rampant in South East Queensland this last couple of months. The droplets in the ears were helping but not making enough of an impact and my husband was hit really hard by this virus so back to Earthclinic I went to do some more research.

I discovered the foot soaking remedy and gave it a go. Lining a large shallow pan with tin foil, I placed a face cloth in and poured about 80mls Hydrogen Peroxide 3% over it. Then my husband placed both feet on top of the face cloth for 5 minutes. He then air-dried his feet for about 10-15 minutes.

About 2 hrs later he reported that the tightness in his chest was significantly reduced and he felt a general overall improvement. The next day (today) he was a lot better, so we did the treatment again and he just continues to slowly improve as the day progresses.

Even though I had the virus last week I woke up this morning again with a scratchy throat and swollen glands so I thought I would give the foot soaking remedy a go as well. By this afternoon I was symptom free.

Once again I am thanking God for this website as I am convinced this remedy has saved my husband weeks and weeks of sickness. As a business owner, he cannot afford to take weeks off. Thank you from the bottom of my heart to the Earthclinic team and all of the helpful posts others have made to add to all of the wisdom available on this website.

For the foot soak in a foil-lined pan with a washcloth, how much water did you add? I'm guessing there was water because 80mls isn't very much liquid.

I have used 3% hydrogen peroxide for years. I have never had the flu injection. I have never gone beyond 24 hours of infectious flu or cold or sore throat. I have found however that some hydroxide seems to be more effective than others. I enjoyed reading about soaking feet and 3% hydrogen peroxide. So I now know that should my 3% not react to that virus, I will straight away soak my feet in the 80 mils of 3% hydrogen peroxide. Wonderful!!!

Have you tried nebuliser with 3% hydrogen peroxide food grade? I do 10:1 water to peroxide. It cleared up a chest infection I had lingering after a really bad flu I caught when I was overseas a couple of years ago...mmm I wonder was it the current dreaded virus? Anyway when this new virus hit the ground running all over the world I grabbed a nebuliser thanks to Dr. Mercola's video and it kicked the end tails of whatever virus I had immediately. Now I use the nebuliser a couple of times a week for it's other health benefits.

Hi:) I just saw and read your message and I too have used h202 in my ears for years and using that treatment has also been a godsend. I learned this treatment from working with German docs while in the Air Force. What I recommend is leaving the h202 in your ears longer like at least 10 min or until the bubbles stop and if you don't have bubbles let stay in there anyway for at least 10 mins. I do 15:) This treatment has also helped with sinus infections as well. And I have learned in my experience to do it twice in a day if needed like a couple of hours between treatments as I have found it sometimes it just takes more time. There you go, so for what it's worth, that is what I think:) Good luck and live in perfect health. Mike

I read about putting 3 drops of hydrogen peroxide in your ears to stop colds & flu on Dr Mercolas's website and thought it was quite interesting. They claimed it was successful in 80% of cases if administered within 12-16 hours of the first symptoms appearing.

It's midwinter here and everyone in the office came down with a cold, and shortly after I woke with a headache and a sore throat.

I checked on earthclinic that others had tried this first, which they had, so that night after work I syringed warmed hydrogen peroxide into my ear canal, (probably more than 3 drops as a pretty much filled the ear canal) lay down with a timer for 10 mins on each side, drank down a large dose of vitamin c, and the next day no symptoms of a cold what-so-ever. I wouldn't have believed it if I hadn't tried it myself. It's a fantastic remedy and over 3 weeks later I still haven't had a cold. I've tried putting the drops in since but they didn't bubble like the first time which I assume means no infection was present.

I would recommend trying this if you're in the first stages of cold symptoms as you have nothing to lose.

Two of my kids (14 and 18) came down with colds this week and then started running fevers. My daughter has also been vomitting so has not been able to do the lysine/Vit C remedy for flu.

I don't beleive that there is enough data to support H2O2 intake while breastfeeding. Doing so seems excessively risky to me. Does it not to you? Common sense and risk assessment must rule the day in the absence of data, in my opinion.

I have a question about using H202 as a cold/flu relief. Recently I used 3% grade in my ears as instructed. No problems at all, until I emptied out my right ear after the bubbling subsided. I noticed that the cartilige on the outside of my ear around the opening for the ear canal was red, was that just an irritation from the bubbling or does it usually do that with an infected ear? Thanks.


I'm not a nurse or a doctor, but I would think when there's redness, it usually means there's an infection. Redness is never a good sign...

H2O2 in ear for colds: I get sick almost every month, usually with a bad cold during, or right after, my period. I tried H2O2 in my ears right when I was getting that familiar tingle in the back of my throat and tired feeling I always get before a cold. I used about a half a capful of 3% hydrogen peroxide poured into my ears, one at a time, lying on my side and let it sit and fizz for about 10 minutes each before dumping it out. The itchy feeling started disappearing right away and the next day I wasn't sick as I was sure I would be. I normally get sick for a good week or two when I do, so I was really glad it worked!
