I ordered two bottles of this, one for each of my college age daughters who travel by plane to get back and forth to school. They use this spray after traveling to stop anything that they may have picked up in their nose/sinuses as well as any time they start feeling the sniffles coming on. It works amazingly.
this is an absolute essential a couple times a day, especially coming from grocery shopping or when immersed amiong lots of public. I give myself a shot when I get home as a front line agent against covid viruses which stops it in the nasal point of entry and drips down into the throat for added protection.
I have heard about amazing effects of colloidal silver, read reviews here and decided to go for it! Waiting for a good moment to use it, however, it says that it cant be used more than 10 days in a row.
