xlear and covid

We believe in maintaining health through transformational hygiene (proactive health), and Xlear’s xylitol-based products support that goal.

From the time that Ignaz Semmelweiss first wrote about the need for physicians to wash their hands between patients and the time that it became the standard of care (or mandated because it wasn’t being done) was 150 years. Semmelweiss was ridiculed, laughed at, and discredited, but history proved him correct. Washing our hands and nose are simple hygienic ways that we can stop the spread of bacteria and viruses.Washing our hands helps stop the spread of infections, but only because you reduce the transmission of viruses or bacteria from your hands to your mouth, nose, or your eyes where they can easily enter the body. The nose is where most bacteria and viruses enter the body, and that’s precisely why nasal hygiene is so important!

Wouldn’t it make more sense to wash our nose with something that helps to block viral and bacterial adhesion?

Nearly 75% of the visits to primary care physicians in the U.S. are related to upper respiratory issues, and South Africa probably has similar statistics. We can bring that number down significantly by taking primary nasal hygiene more seriously.

Even if and when we’ve been vaccinated, we are still able to transmit the virus, and scientists aren’t certain whether we’re fully protected against newer strains. So in addition to hand-washing and sanitising, we should add nasal hygiene to our defensive armoury.

Dr. Lisa Rohan, a professor at the University of Pittsburgh School of Pharmacy and Magee-Womens Research Institute & Foundation, has the following to say about a nasal spray in general:  “We feel a nasal spray is perfect … to neutralize the virus before it gets into the lungs and causes a lot of clinical complications. One advantage it has over vaccines is its broad spectrum of activity against a number of different coronaviruses. The other benefit is for immunocompromised people, who aren’t successful with vaccines — so this is an alternative for them as well.”

Consider the following scientifically supported facts:

  • 90 percent of the viral load that causes Covid 19 is found in the nose (New England Journal of Medicine)
  • Two recent in-vitro studies have shown that Xlear Nasal Spray kills 99.7% of the SARS-CoV-2 virus (Utah State University, University of Geneva)
  • Xylitol actually blocks the entry of the virus into our cells (University of Tennessee)

Xlear is effectively a natural virucidal and bactericidal nasal spray, making it an excellent preventive aid against not only Covid, but other viruses and bacteria too. So transform your nasal hygiene and make it more effective, by washing your nose with Xlear Nasal Spray.

Xylitol Nasal Irrigation in the Management of Chronic Rhinosinusitis – 2011

 

 

In this pilot study, researchers wanted to find out if irrigating the sinuses with a water-xylitol solution would improve symptoms of people suffering from chronic rhinosinusitis. They concluded, “Xylitol irrigations result in greater improvement of symptoms of chronic rhinosinusitis as compared to saline irrigation.”

Mapping How SARS-CoV-2 Infects the Body – May, 2020

The Three Stages of SARS-CoV-2 Infection – Jul. 2020

 

The paper’s authors show that like other illnesses which affect the lungs, the SARS-CoV-2 virus has three stages of infection, and if left unchecked, it could cause irreversible damage to lungs. They argue medical professionals must give greater attention and treatment in the earlier stages of infection.

Using Nasal Sprays to Combat SARS-CoV-2 – Sept. 2020

 

Researchers concluded that using a nasal spray that deactivates the SARS-CoV-2 virus in the nose, “may not only prevent person-to-person spread of SARS-CoV-2, but may also diminish the severity of disease in patients by limiting spread and decreasing viral load delivered to the lungs.”

Nasal Irrigation Reduces Symptoms Related to SARS-CoV-2 – Sept. 2020

 

In this interim analysis, researchers evaluated the effect irrigating the nose and sinuses had on reducing symptoms related to SARS-CoV-2. They found, “The effect of nasal irrigation on symptom resolution was substantial, with nasal congestion and headache resolving a median of 7 to 9 days earlier in the intervention groups”. Our analysis suggests that nasal irrigations may shorten symptom duration and may have potential as a widely available and inexpensive intervention to reduce disease burden among those affected.”

Further Evidence of Xylitol’s Effectiveness Against SARS-CoV-2, H1N1, and Other Viruses – Jan. 2021

In this study researchers used an electron microscope to take pictures of xylitol’s and grapefruit seed extract’s (GSE) interaction with the SARS-CoV-2 virus. They concluded, “Combination therapy with GSE and xylitol may prevent spread of viral respiratory infections not just for SAR-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.”

Comprehensive Literature Review of Intranasal Therapy Against SARS-CoV-2 – Jan. 2021

In this review, researchers looked at all the studies talking about intranasal therapy in fighting against SARS-CoV-2. They concluded, “Based on the literature review, it is encouraging to note that studies reviewed note that using nasal spray with antiviral properties has promising efficiency and safety in the treatment and prophylaxis against SARS-CoV-2…We propose that intranasal administration of antiviral and virucidal therapies decrease the viral activity in the nasal pathway, thus preventing disease transmission, expedite recovery of patients, decrease severity of symptoms, reduce hospitalization, and mortality.”
