Nasal spray
The 2.02 protocol suggests:
Xlear makes a nasal spray that contains Xylitol and Grapefruit seed extract. Using this in the morning and before bed will break down any biofilms and drain them out of your sinuses. It can be used as a prophylaxis for 4 to 6 hours of protection when around large groups of people or sick people.
Space Cowboy has shared a homemade recipe for this nasal spray: [1]
Here is the recipe:
>40ml saline solution
>1 teaspoon Birch Xylitol
>4 drops GSE (Nutribiotic 33% solution)
And that's it. Saline can be made at home or purchased pre mixed. If making your own saline, only use purified or distilled water. If using tap water, ensure you thoroughly boil it before using.
The GSE concentration keeps the solution sterile in combination with Xylitol at approximately 10% concentration. Allow the solution to sit for 2 hours before using.
