Flushing Your Sinuses with Hydrogen Peroxide

Updated: Apr 14, 2022

"Regular use of this procedure has produced miraculous improvement in my patients with chronic allergies, post-nasal drip, sore throats, chronic headaches, and chronic fatigue."

The sun was shining brightly and there was a strong wind. Throughout the day, the trees danced in the breeze and the pollen swirled through the air.

After several hours of gardening, my sinuses had done their job well. They had steadily collected and filtered out dust, pollen, insect detritus, and gas engine fumes.

But how do your sinuses get rid of all this waste? They usually produce mucous which is moved along by delicate hair-like structures called cilia. That is, if the delicate cells lining your sinuses have not become dysfunctional and damaged from aging, poor nutrition, smoking, exposure to environmental chemicals (chlorine, ammonia, gasoline, etc.), as well as exposure to steroid sprays like Flonase and decongestant sprays like Afrin.

The Overlooked Microbiome

We often focus on the gut when referring to our microbiome. In fact, any part of your body that is open to the environment and normally supports a population of bacteria and other organisms is, by definition, a microbiome.

Your sinuses are normally populated by what is hopefully a friendly population of healthy bacteria and other organisms. If your sinuses become stressed or unhealthy, this microbiome can become overgrown with many more organisms than is healthy. In fact, your sinuses can right now be harboring respiratory viruses, fungal spores or even staph bacteria, just waiting for your resistance to wane before progressing to an acute infection.

Sinus Flushing with Hydrogen Peroxide

For the past couple of years, I have asked many of my patients to begin flushing their sinuses on a regular basis using an inexpensive portable nebulizer that infuses a mist of dilute, medical-grade hydrogen peroxide which they inhale through their nose for a period of 6 to 10 minutes several times a week.

While completely safe to the patient, the hydrogen peroxide concentration I recommend has been shown to be toxic to bacteria and viruses. This procedure cleanses your sinuses and ‘prunes’ what is often an overgrowth of unhealthy organisms.

Regular use of this procedure has produced miraculous improvement in my patients with chronic allergies, post-nasal drip, sore throats, chronic headach chronic fatigue.

Dr Kaiser, I have been nebulizing with hydrogen peroxide, following your instructions to the letter. After three weeks, there were streaks of blood when I blew my nose. The blood was bright red. Should I stop? I have post-nasal drip. I also sneeze a lot within seconds of inhaling. Sneezing stops after I stop the nebulizer.


Mae, figure this out yourself. If you have the symptoms that you described, you are having an unhealthy reaction to this faulty procedure. You should stop immediately, and perhaps see a real doctor if the symptoms continue. Conventional medical wisdom is that there is no convincing proof that hydrogen peroxide rinsing helps any nasal problems, and that since hydrogen peroxide is a caustic chemical, continued use is going to cause damage to the delicate nasal tissues.
