The Journal of the American Medical Association states that using a nasal spray that deactivates the Covid virus in the nose, may not only prevent person-to-person spread of SARS-CoV-2, but may also diminish the severity of the disease in patients by limiting spread and decreasing viral load delivered to the lungs. Researchers have identified two agents: xylitol and grapefruit seed extract, which, when administered in the form of nasal sprays help reduce COVID-19 symptoms in patients. More from Andy Cook, the owner of Exceptional Health, who imports a nasal spray that contains xylitol and grapefruit seed extract.
