Should be in your Medicine Cabinet
I use this regularly now, especially at any sign of sneezing or stuffiness....it burns a bit but goes away fast (like mild wasabi haha) and open the sinuses up.  Seems to keep germs from going crazy and moistens the nasal passages.  I even use it on my 4 year old for stuffiness and germ control.  I will travel with this on every plane ride.  Prior to getting this I would swab my nasal passages with the diluted oil version in the dropper bottle which is also good.
