I started using this OTC product this summer after an 11 day, symptomatic C19 infection. No problems since, and very easy to use. I wonder if spicy, mucous generating food would have a similar effect if taken daily? Just one anecdotal data point and one crazy thought. Carry on.

A word of caution to anyone with dogs ... xylitol is highly toxic to them, so be sure to keep anything in your home containing xylitol out of pupper's reach. It's in lots of stuff today, including certain peanut butters. And you probably shouldn't give or get puppy kisses right after using your xylitol nasal spray, either!

Just to think that something as simple as a sugar could have prevented all this chaos and misery. I use a nasal Iodine spray.

I’ve been using this nasal spray for years! What a fantastic discovery. So happy you shared this.

Here’s the study.

Want to bet how long it takes for W.HO., or NIH to have a study that tries to debunk it?

We need to share this & start being a little louder. And call out their faulty studies, like the High Dose Ivermectin JAMA Study, that had participants start no more than 7 days of initial positive Covid test Jan. 20, 2023. That’s not really “ early” intervention.

I have been using Xlear for a number of years, more related to my sinus issues than to deter covid. It is interesting that Xlear was prohibited from indicating that it had any effect against covid (even though it does). But interestingly, I recall reading that a good portion of its efficacy was not necessarily the xylitol, but rather the grapefruit seed extract that is also in it. Whatever the reason, I highly recommend it.

Wow, great news! Thank you!

As the developer of this spray let me lend a voice to how it works. It’s marketed as a nose wash because the FDA has no interest in hygiene—thanks to the soap industry back when the FDA was started not wanting anything to do with drugs.

At the same time I like to think of Hippocrates, the father of western medicine, telling us that our foods should be our drugs. I call foods like xylitol “Hippocratic Drugs”.

There are two ways xylitol works in the nose: it optimizes our normal nasal washing, and; it interferes with microbial adherence. Many call it a nose wash, but that’s misleading. The combination of mucus, which holds on to all the garbage—including microbes, and the microscopic hairs—called cilia—that sweep it all out, are what make up our primary nasal defenses.

We developed this defense when we grew up in the tropics, where the humidity is normally higher than 50%, and when it’s that high respiratory infections are far less—one of the reasons Africa has had less problems with COVID. But we moved to temperate zones, and indoors where we could warm the air and be comfortable. But warming the air reduces the humidity and in our comfortable homes the optimal humidity is usually seen as in the 30% range—which handicaps the defense. A crippled defense means people get sick. Xylitol works osmotically to pull water into the nose so the optimal level is restored. It doesn’t wash your nose; it helps the nose wash itself. And a clean nose, as many of you who are users witness, means less respiratory illness, both infectious and allergenic—and that includes asthma.

The interference with how microbes hold on is important. Long ago Bill Costerton, who is know as the father of slime due to his interest in the microbial families at the bottom of stream beds, showed us that all natural microbes, both bacteria and viruses, are normally covered with a network of sugars and sugar complexes—they’re called glycans—and one fo the things they do is provide a means for the microbe to dock on the glycans of the host. Costerton wrote in a 1977 issue of Scientific American that the sugars provided several ways to cope with the infection—and he was right—and xylitol is a flexible sugar/glycan-like that can look like many of those target glycans.

The important thing to remember is that xylitol doesn’t kill microbes; it negotiates—it says, ‘shape up or ship out.’ When we threaten microbes we push them to mutate more often to deal with the threat, so they learn to resist—and now we have many die from antimicrobial resistant organisms. Negotiating pushes them in the other direction; it’s called commensalism, it’s where the microbe learns to live with us in a helpful way.

So why haven’t we followed this path?

Because there’s no money in it. When I found out how nit picking the FDA was and realized I did not have pharmaceutical grade funding to jump through their hoops I called the pharmaceutical industry. Their initial interest evaporated when they found that they could not patent the active substance since it was a food. It costs over a million dollars to jump through the FDA hoops and they need a secure profit so they can price it high enough to recoup the expense. With a food people would mix it up in their kitchens if it was priced as a drug.

Amazing how our Big Pharma - Political - Administration system is so corrupt and third world leaning. This entire complex must be destroyed and those in it as well. As to the politicians, one could argue they are traitors to their oath of office and should face the consequences of their actions. True also for the administration lackeys. #NoAmnesty #NoQuarter #NeverForget #resist #DoNotComply

I believe it was you, Dr. McC, who recommended this a couple years ago. Between this and ivermectin when I finally got covid (slacked off on the xclear), I had no significant symptoms. Also noticed my allergy symptoms were way less intense when using xclear. I've shared these experiences repeatedly but so far no minds changed. Their loss but still heartbreaking to see people suffering from heart issues who had none pre-vax. What will it take?

Woke and I have been using for almost two years now.

I recently used 0.5% Hydrogen Peroxide nasal irrigation and gargled with with 3% Hydrogen Peroxide 4 or 5 times per day. I assume that the the Xylitol nasal spray is more convenient and better tolerated than 0.5% Hydrogen Peroxide nasal irrigation. Is it equally effective aborting Covid 19 infection? Povidone Iodine a bit messy.

Sorry, the links to the studies of Balmforth and Soler don‘t work!

I have been using Xlear nearly every day since I first learned about such benefits in late 2020. (Yes, it was already known back then, but of course the MSM swept it under the rug.) And I have rarely got sick since, maybe one or two colds, and what I think was one brief and mild case of unconfirmed Omicron BA.1 that felt like a cross between a cold and flu. That's it. And now the RCT confirms its benefits.

Dumb question maybe, is this the saline type or decongestant? I could find the study myself & read it. 🙈 Thanks!

Also helps with stinking nose and anosmia (post-* or LHCS).

Add some anti-allergy spray.

Alternating, also one inorganic antiseptic spray. Of course all have also systemic therapeutic range limited by NOAEL. NO observeable events (level of dosing).

Using this triangle or 2 of 3 yields quite perfect protection each intervention alone can not if R-value of pathogens is rising due to immune pressure (not necessary while “not fighting” it, like deliberately NOT doing magic, I learned from Dr. J:)

Ever heard a med showing this properties? Except glycans ie Xylitol or DMSO perhaps?

We should do a list!
