My erythritol/xylitol nasal spray recipe

NOTE: I’m not a doctor, and this is NOT a substitute for your doctor’s advice. This nasal spray is IN ADDITION to other precautions, NOT a replacement.

I’ve come up with my best solution for making and using an erythritol/xylitol nasal spray. I’m getting into the habit of using this multiple times per day. Think of this as the new washing your hands. Given that COVID-19 is airborne, I’d expect this to be FAR more effective than washing your hands. (While some diseases can spread through contaminated surfaces, COVID-19 is not one of them.)



  • 1 cup of distilled water
  • 1/2 teaspoon of sea salt (or any other pure salt without anti-caking agents)
  • 1/2 teaspoon of baking soda
  • 1/4 teaspoon of erythritol
  • 1/4 teaspoon of xylitol OR an additional 1/4 teaspoon of erythritol
  • 4 drops of grapefruit seed extract
  • OPTIONAL: a dash of bromelain powder


  • Use of this nasal spray should be in ADDITION to other precautions, NOT a substitute. Think of this as the new brushing your teeth or the new washing your hands.
  • If you have pets, please skip the xylitol and use the additional erythritol instead. Xylitol is harmful to dogs and cats.
  • To obtain spray bottles, just buy a few bottles of cheap and generic nasal spray. Target’s Up & Up (1.5 ounces) is the cheapest product I found. Cheaper is better, because you will dump the original saline solution.
  • The grapefruit seed extract is a preservative.
  • The erythritol and xylitol are sugar alcohols that are said to impede viruses from attaching to cells.
  • Anti-caking agents in salt may irritate the nasal passages.
  • The optional bromelain powder is the only ingredient that you’ll have to buy online. Bromelain is the enzyme in pineapple. It may fight inflammation and break down viral spike proteins.
  • The other ingredients are widely available. Grapefruit seed extract, erythritol, and xylitol are available at Whole Foods and Vitamin Shoppe.

DIRECTIONS (for making the spray)

  1. If the nasal spray bottles are new, remove the wrapper.
  2. Remove the outer cap and then the nozzle. Pour the contents down the drain.
  3. If you’ve already used the nasal spray bottles, please wash the bottles, nozzles, and caps with water and dish soap.
  4. Make the new nasal spray solution by mixing the ingredients into the distilled water.
  5. Pour the new nasal spray solution into one of the bottles, but stop before it’s completely full. Put the nozzle and then the cap back onto the bottle.
  6. Repeat the above step for the other bottles until there’s no additional nasal spray solution left.

DIRECTIONS (practice using the spray)

  1. If you’re not sure how to use the spray, take a bottle of the nasal spray outside to practice.
  2. Hold the nasal spray bottle upright or nearly upright. Give it a quick squeeze to spray out a fine mist.
  3. Hold the nasal spray bottle upright or nearly upright. Give it a longer squeeze to spray out a stream instead of a mist.

DIRECTIONS (using the spray)

  1. Hold the nasal spray upright and insert it into one of your nostrils. Tilt your head slightly so that the nozzle is aimed slightly towards the outside of your nose. Give the bottle a quick squeeze.
  2. Repeat the above step but tilt your head slightly so that the nozzle is aimed straight up your nose. Give the bottle a quick squeeze.
  3. Repeat the above steps for your other nostril.

Note to all of us.

My dad a doctor has said clearly to me that using solutions in the nose can cause or spread infections. That certain practices even by doctors can cause infections and repeat infections at that.

That the device that washes the nose one nostril through to the other with water can spread infections.

Be careful in your nose care. Seek professional opinions.

What I’m doing and advocating is spraying the nose with a quick fine mist. This is like Xlear but cheaper.

It’s a good idea to go outside and practice spraying/squirting the fluid straight up into the air so that you know what you’re doing.

And of course, you should not share your nasal spray bottle with anyone else. Each person should have his/her own dedicated personal nasal spray bottle.

The problem is you are giving generic advice. If someone reading about this has a sinus infection they can spread that infection further into their nasal cavity. Then have recurrences etc…it is important to try and leave somethings to professional doctors and nurses. You also do not know if a reader will use any ingredients that have more bacteria in them.

I agree DV. Edit your post, and drop a liability disclaimer that “this is not medical advice, you are not a Dr, blah blah, seek medical attention from professionals etc”.

Other than that, though @DopplerValue I might try your recipe.

I have a 4 or 6 oz squeeze bottle of nasal saline OTC that 3 years old. I stick it in my nose about 2 or 3 x per year. It’s OTC. I suspect there’s a “liability disclaimer” on it.

Here’s my method.
I’m not a Dr, this is not medical advice, use at your own risk. If you have a medical condition see a Dr, blah blah blah.

Step up to a water source. I have used water fountain, tap water, and bottled water. Put a TBSP puddle in the palm of your hand, hold the little puddle of water under one nostril, close other nostril and snort the water.
Do this a couple times per nostril, then blow your nose.
Maybe wash your hand first? You are the judge of that. (Cause I’m not your Dr or your mama.)

Alternatively, put a couple TBSP water in a cup, add a dash of salt, and (optional) a dash of baking soda. Stir, warm it briefly in microwave, you want it “skin” Temp.
Put some solution in the palm of your hand, snort it.
.*** If the solution is hot to your palm, it’s TOO hot, let it cool down!

DVs recipe may actually be anti viral. My recipe is mostly just a nasal wash.

If there’s any solution left over, add a bunch of salt, warm it, then gargle.

Be well, do good things, and give yourself a hug.

ralph doesn’t believe everything requires a nanny. But, in the interest of CYA, disclaimers for the litigious, etc: I’m not a Dr, I ain’t telling anyone what to do, you’re your own boss, do your own due diligence, take some personal responsibility, etc.
This goes for anything and everything I write, or say, and, at some point, that I even think.


Then, bang it 50 times on a leather bound copy of the bible … King James version … take a teaspoon of the brew, dilute it in a gallon of water, repeat 100 times and voila a homeopathic brew to cure whatever ails you.



Shakespeare still has the edge:

Eye of newt, and toe of frog,
Wool of bat, and tongue of dog,
Adder’s fork, and blind-worm’s sting,
Lizard’s leg, and owlet’s wing,—
For a charm of powerful trouble,
Like a hell-broth boil and bubble.
Double, double toil and trouble;
Fire burn, and caldron bubble.

You think you’re joking. Check out Oscillococcinum (I think that’s the spelling) for flu. Or, better yet, essence of Berlin Wall.

When I went to get my flu shot I saw the flu remedy on the shelves at Walgreens. In the general chit chat with the pharmacist, I mentioned that if the vaccine let me down, it was good they had a placebo for sale. She didn’t know what I meant…was even more gobsmacked to learn what wasn’t in the sugar pill.

Quack! Quack!
