Eucalyptus Oil

On occasion I'll have an ailment where I'll try a natural remedy and quite a lot of the time I feel that it may have helped, I don't think I've ever tried eucalyptus for anything, I may have had it in tea when I've had the flue, but other than that I can't recall. It does have a pretty strong smell and I can imagine it working a lot like some of the more well known remedies out there.
