This is a nasal spray designed to ward off colds, if used in a timely way. So as soon as you sneeze, have a tickly throat, use the spray. It stops your early symptoms from developing into a fully fledged cold. IT WORKS!
At last, I've found something that actually stops colds! I didn't believe the ads, but when I saw excellent reviews in mags, I gave it a try.
Yippeeeeeeeeee!
