Colds are going around my kids school so a friend introduced me to Airborne yesterday when we were at Trader Joe's. It is a herbal supplement that you take either at the beginning of a cold or right before you go someplace very crowed (cruise, airplane ride). They even have a formula for kids. Created by a school teacher. My husband was feeling like a cold was coming on and he took some a felt a little better. My daughter's teacher started taking it 2 days ago because she was really sick, and it cleared up her nose. It also has ginger in it so it would help nausea, too. It's something to think about...definately going to use it before we go (and the kids, too). Oh, an added benefit, it gives you a little extra energy.
