Saline Nasal Sprays

Even though we’ve been fighting and learning from the coronavirus pandemic for over a year now, there are still many things we need to learn. There have been many solutions to stop the spread of COVID-19 and to prepare your immune system against it.

And as it turns out, the COVID vaccine might not be the only way to fight this disease. Some recent studies have found that this over-the-counter medication can also help to kill COVID. And no, it isn’t a vaccine, it’s a nasal spray.

3. How Can a Nasal Spray Kill COVID?

According to a recent study from December 2020, researchers from Northwestern University and Utah State University tested the effectiveness of a nasal spray called Xleas Sinus Care (GSE) against the cultures of SARS-CoV-2, which is the virus that causes COVID.

The results were more than interesting. They showed that, after 25 minutes of contact with the cultures of COVID, the virus had been dramatically reduced and the threat had been neutralized by this nasal spray.

This was thanks to a chemical called xylitol, which is a sweetener that has proven to be effective in reducing the severity of viral infections. The Xlear Sinus Care nasal spray contains 11% xylitol, which was more than enough to neutralize the COVID disease.

The authors consider xylitol to be an effective component against COVID and many other viral respiratory infections.

“Combination therapy with GSE and xylitol may prevent spread of viral respiratory infections, not just for SARS-CoV-2 but also for future H1N1 or other viral epidemics. GSE significantly reduces the viral load while xylitol prevents the virus attachment to the core protein on the cell wall,” explained the researchers in their study.

2. There Are More Studies Supporting This Nasal Spray


This wasn’t the only study that showed the benefits of using the Xlear Sinus Care nasal spray. Another group of researchers from Larkin Community Hospital in South Miami applied the Xlear nasal spray on three different patients from different age groups who tested positive for Coronavirus.

They gave the patients a total of two spritzers every six hours on each nostril. The results were similar to the study conducted in December 2020, and the patients showed great improvements when in their treatment. This determined that this nasal spray, and xylitol to be more specific, could play a significant role in future cases of COVID-19 on patients.

“(Each patient) demonstrated an improvement in the symptoms and a reduction in the clinical course post use of xylitol plus GSE in the form of a nasal spray, commercially available as Xlear nasal spray, as an adjunct to their ongoing treatment,” said the researchers from Larkin. “This combination could play a potential role in improving the outcome in mild to moderate COVID-19 patients.”

Of course, this doesn’t necessarily mean that the Xlear Sinus Care nasal spray would be effective on a massive scale. That’s why the researchers explained that there need to be more studies related to this treatment.

“While relatively safe for general use, larger randomized, placebo-controlled clinical trial studies are mandated which could shed further light on this topic.”

It’s not all about the nasal spray, but having clean nasal passages may reduce viral infections as well. That’s why doctor Gustavo Ferrer, from Aventura Hospital and Medical Center in Aventura, Florida, who was part of the teams behind both studies, recommends cleaning your nostrils regularly.

“Studies show that regular nasal cleansing may help reduce viral infections, including from the SARS-CoV-2 virus,” said Ferrer. Basically, Ferrer explains that cleansing the nose means less virus, and it also means less risk of infection.

That’s why, in addition to the already mentioned Xlear Sinus Care nasal spray, there are other nasal sprays being developed to help fight against the coronavirus pandemic.

In the UK, a team of scientists is working on a COVID-blocking nose spray that uses an antiviral agent and a thickening solution that traps the COVID virus and stops it from spreading across your body.
