Elderberry works wonders! We found it in Amsterdam in 2016. I caught the flu on the plane over for SteemFest. It's a good as a preventative during cold/flu season and great to shorten illnesses when you're already sick. I also use this grapefruit seed extract nasal spray before/after I fly or am exposed to a sick person. They say if you flush out your nasal cavities with this no more than three hours after exposure you can sometimes prevent yourself from getting sick.
Oh wow, that is cool. I have never heard of that for your nose before. I have some flonase I use every now and then, but nothing really organic. We are going to give the elderberry syrup a go this winter and see how it works out for us.
