Colds and Flu

I have been using the h2o2 drops in my ears for 2 years now. Since that time I have been cold and flu free. I used to get them 2x a year plus terrible sinus infections. What a relief! I share it with everyone, even total strangers in stores if I see they have a cold.

By accident I put a couple of drops of the 29% H202 in my ear (forgot I had to dilute it down). My ear was fizzing and bubbling. It's been about 40 minutes the fizzing has just stopped but I'm not sure if my ear feels funny. Am I ok? Did I do something seriously wrong? Now, I see on this site they say to dilute it for putting in ears. Thank you for your help! Lisa

I have found that peroxide in the ear can stop a cold even after it starts. I lucked up when doing this method, I didn't know about these home remedies then, I was just off from work because I was sick and decided to clean out my ears because I had extra time. Gargling might help to break up irritation and mucus in the throat. I say this because my ears nose and mouth don't seem to be as closed off from on another as the average person. After adding peroxide in my ears, I immediately tasted it in my mouth (really in the back of my throat). It felt like I needed to belch, and when I did, all the stuff in my throat came up. It was weird for me but it does seem to break up and stop symptoms of colds.

I gargled with a capful of hydrogen peroxide mixed into 1/4 cup of water and also swished it around my mouth and the next morning my cold was gone.

I used the hydrogen peroxide in the ears at the first sign of a runny nose and sore throat. A half an hour later I felt great and I still feel great today.

Yes, it works! I felt the usual symptoms of a cold last week - low energy, swollen lymphs, etc. and promptly added hydrogen peroxide to each ear for about a minute. I felt better immediately and never got the cold.

I tried using hydrogen peroxide in my ear last night to ward off the beginnings of a cold. It worked fabulously in my left ear; bubbled and fizzed, then drained out smoothly. Really quite pleasant. So I went on to my right ear. It will not drain out! My sinus issues are much improved, and I slept fine, but this morning my right ear is still clogged and beginning to ache. I tried the hydrogen peroxide again, hoping it would sort out whatever had gone wrong. But no luck. If it had worked the same in both ears I would be quite pleased with the home-cure, but as it's left me with a whole new pain to deal with ... I don't think I'll try it again.

I have never ever recommended the use of Hydrogen peroxide in the ears. Yes H2O2 works very well, but not by the ear. It works best when taken internally. Especially when you also add a small amount of vinegar. (It becomes peracetic acid, which is great medicine against SARS - sars don't like acid). For me the most efficient way to get H2O2 into my system without doing dubious things such as IV is to slosh or spray 3% H2O2 on my arms, legs, feet, hands, neck, chest and back. It is much more efficient than putting them in your ears. Of course if you want to get rid of ear wax using H2O2 this is o.k. but not as a cold prevention. A cold prevention or viral outbreak would have been much more effective to use it via mouth wash and putting on skin. Simple reason: your body's skin have the largest areas for H2O2 absorption. H2O2 gets absorbed through the skin quite more efficiently than the intestinal tract, but intestinal tract is also important to take some H2O2 to clear up the pathogens. By the way, viruses also get absorbed through the skin this way to by actions of Langerhan's cells, which unfortunately goes directly to the lymph system and destroys your immune system just the same. To prevent tricky viruses, use H2O2 frequently on the skin. It prevents such from destroying your most prized possession of your body necessary to maintain health your immune system. My favorite way to rid of pathogens, at least no. 1 is to slosh my mouth (after brushing teeth WITHOUT fluoride) using 3% H2O2. I now do this every day. Foams just come shooting out, just to show you how much bacteria I have. I will not recommend anyone doing 3% just start with 0.5-1% H2O2 and once you get use to it you can work yourself up as best as you see fit. A majority of people are much more sensitive than me therefore please lean on the safe side. I am not totally successful in killing of pathogens with a clear rate of success, but H2O2 is the best I have seen so far.

Colds, Sinus Infections

I saw your article and the warning "do not spray in nose". I do. I have been doing so for almost three years and I have only had one very minor cold since. Before that I has sinus infection after sinus infection. I used to use half and half saline nose spray with peroxide, now I just use 3% peroxide. If I feel the slightest cold symptom (congestion, that funny taste, ect) I use it three to six times daily and usually kill the cold before I start feeling bad. The last little cold I got was because I hadn't done my regular one or twice a week regimen for about a month. Everyone who I have told about this and actually tried it has had some positive results with no negative results yet.

I was Dx with COPD a few yrs back and none of the inhalers perscribed helped. I started doing a natural remedy and have been drinking the 35% food grade H2O2 diluted at a ratio of 5 drops H2O2 to 8 oz distilled water once a day and I have more energy and have not been on the inhalers for 2 months now. I can breathe alot easier. In this suffocating heat I did not have any trouble.

Hi Marti, good post, what brand you used and what time of the day you drink it?

Dechlorinating Water

Posted by Marla (Atlanta, Georgia, Usa) on 02/25/2011

We all know that chlorine is in most tap water, and that it's not good for us. Furthermore, when chlorine meets water or H2O2, it generates chlorine gas, which is deadly and was used as a chemical weapon by the Germans in World War I (this is the awful smell you get when cleaning with bleach water and why you should use it in well-ventilated areas emedicine.medscape.com/article/820779-overview). Because of this, it is not safe to add hydrogen peroxide (H2O2) to chlorinated tap water and drink it right down for your oxygen therapy.

However, if your water ph is 7.0 or higher, H2O2 can be used to dechlorinate the water first, allow the chlorine gas to escape (www.h2o2.com/industrial/applications.aspx?pid=107&name=Dechlorination), and then the water will be safe to use for oxygen/hydrogen peroxide therapy.

Further, it only takes a single drop per gallon to dechlorinate most drinking water. (See below for math ) I have not been able to discover the time necessary for the chlorine to be fully liberated, so to be safe, I would agitate the water periodically and not use it for 24 hours or so.

How I calculated 1 drop per gallon:

1.8mg/l Cl common post-treatment level (check with your water provider for specifics)

100000 gal H2Orequires 0.2 gal 50% H202 to dechlorinate (www.h2o2.com/Calculator.aspx)

There are 90840 drops in a gallon

0.2 gal = 18168 drops 50% H2O2 to treat 100000 gal H2O with Cl

Moving the decimal gets us 1.8168 drops for 10.0000 gal

3% H2O2 is 16.666% strength of 50% H2O2, so 3% hydrogen peroxide requires 6x amount of 50%

10.9008 drops for 10 gal = 1 drop per gallon

Simple and cheap to dechlorinate your tap water at home!

One drop did not dechlorinate a gallon after 24 hours. I used a electronic sensor

Dental Care

I recently bought a bottle of 3% HP because my tooth was in pain every day and night for about 2wks. And my dental appt. was exactly 1 month away, I would either have to find another dentist or fix the pain myself, since the pain killers I was taking wasn't effective enough to help. I started using the HP and the pain eased significantly, by the next day I really wasn't in any pain just uncomfortable feeling that the swelling left behind. After a couple of more days of swoshing it around in my mouth a few times a day, there wasn't anymore pain and know I have been pain free of this toothache now for the second wk. And I still have 11 more days until my dental appt. on Dec. 4th. Thanks for HP. It saved my toothache from aching.

I use HP in my water flooser (Water pik). I fill it almost up to the top with water, and put a splash of HP in the water pik cistern - that is the receptacle wtih the water in it. I do this about 2-3 times a week. Also keep the pressure setting at 50% or below. Don't focus too much on one tooth, move around quickly, and don't do this much more often, because eventually it will erode your gums if you use it to excess. I use my orthodontic tip to splay the pressure out more so the stream is less pointed. Doing this a few times a week keeps my teeth in great shape. Great before upcoming interviews, big social events etc. It is like the water jet in the dentist except better! You can add your own stuff to it, and change the pressure. I use non-alcoholic mouthwash in my W. P. On the off days. This is also brilliant if you have braces or other orthodontics and can't floss normally.

Just started with 3% solution mouthwash, Initially, there was a lot of foam and bubbles coming out from my gums and tongue. Must be the bacteria being killed by the H2O2. Subsequently after three days of rinsing twice a day, my swollen gums have receeded and the sore on the side of my tongue has turned white and the pain diasappeared. Even my toothache was gone. Except for the tingling sensation on the tongue, the only other unpreferred sensation was the taste. So I mixed it with a few drops of astringosol to have that minty taste. Is this OK? Has anyone out there tried this?

Hi good to hear someone is using hydrogen peroxide. I use it for brushing my teeth with baking soda. It's the main ingredient in tooth whitening products so its all good. I only use it a few times a week. I also have it in a spray bottle in a 3% diluted mixture and use it for a number of remedies. Great for killing nasty bacteria. I also spray it down my ear when I get a sore ear and throat and it bubbles and lie down for 10 minutes then tip it out and it heals the ear. Sorry I went off track a bit. Get excited when good products help people. :o)

Someone help me with this. I'm not able to find hp 3% anywhere so would using 5% to 7% as a mouthwash be harmful? pls rply at its earliest

You will need to dilute it down to 3% minimum. So at 6%, just add the same amount of water, at 7% add more than that. Even start out diluting it a bit more.
