Some viruses live in the nasopharynx (the part of the throat that goes up into the nasal cavity) for any duration of time up to 10 days before causing respiratory problems and inflammation. However, many compounds kill viruses upon contact, such as hydrogen peroxide, iodine, essential oils, and saline (saltwater).

There are various solutions that have been used as prophylactic and healing measures for COVID-19. It’s best to use distilled water, as tap water can contain an ameba called Naegleria fowleri that is able to trigger a dangerous brain infection. Additionally, tap water has minerals and can have bacteria that irritate nasal cavities. To prepare, combine one of the following solutions in a neti pot.

The solutions:

  • 2 teaspoons betadine (povidone iodine) and 6 ounces water. You can use 1/2 teaspoon Lugol’s iodine instead.


  • 1/2 to 1 tablespoon of 3 percent food-grade hydrogen peroxide and 8 ounces pure warm water


  • 1 teaspoon colloidal silver in 8 ounces pure warm water

To prevent burning in the nasal cavity, stir 1/4 to 1/2 teaspoon kosher or unrefined salt into the solution until dissolved.

Use a neti pot to rinse the sinus cavity using a few ounces of the solution per nostril. Gargle with the rest of the solution and spit it out. It’s advised to use a glass or ceramic neti pot to avoid plastic exposure.

Seeking to prevent or aid the body in illness? Do a nasal rinse or nasal spray with the solution above followed by mouthwash every time you’re in a densely populated public place or have a known exposure. This can be done up to twice daily.

If you have an active infection, rinse up to four times daily. Follow it up with a quality mouthwash. I favor mouthwashes utilizing antimicrobial essential oils such as cinnamon bark, orange, clove, rosemary, and eucalyptus.

Keep in mind, overuse of nasal and oral virucides has the potential to negatively impact the microbiome within the sinus cavity. The delicate balance of microflora inhabiting the area can be disrupted with constant exposure to antimicrobials such as iodine, colloidal silver, or hydrogen peroxide.

While natural compounds are usually more protective than synthetic ingredients that go in and wipe out the microbial ecosystem, it’s wise to be judicious with frequency of use. This strategy is intended for short-term use. Please keep in mind that this isn’t medical advice and is intended for educational purposes only. Please check with your doctor before starting this therapy.

With up to 75 percent effectiveness, nasal virucidals should be one of our primary methods of contagion control. I wish this were a bigger part of the mainstream conversation and approach.

  1. Hi there! Would you mind if I share your blog with my zynga group? There’s a lot of people that I think would really appreciate your content. Please let me know. Thank you

  2. Thanks for the article. My partner and i have continually observed that the majority of people are desperate to lose weight as they wish to look slim and attractive. However, they do not usually realize that there are additional benefits to losing weight as well. Doctors claim that overweight people suffer from a variety of ailments that can be perfectely attributed to their own excess weight. Fortunately that people who definitely are overweight and suffering from a variety of diseases can help to eliminate the severity of their particular illnesses by means of losing weight. It is possible to see a continuous but marked improvement with health while even a slight amount of weight reduction is attained.
