I've pinned this before... But I'm pinning it again, because it really DOES work. Like gangbusters. Eucalyptus oil on the bottom of the feet (and I put a few drops on the pillow, for good measure), and coughs are GONE. My hacking, waking-up-every-half-hour-asthmatic baby girl is currently sound asleep, thanks to this. Do it.
