Basically a physical barrier coating the nasal passages. For me and my allergies, it&amp;#x27;s super effective.&lt;p&gt;Never thought about using it to block viral infections, but it makes sense: coating the nasal passages with artificial &amp;quot;mucus-like substance&amp;quot; so particles don&amp;#x27;t reach the membranes.
