A remedy to try to clear a cold ridden snotty nose..... Out front of a local 'bing-bong' shop a few weeks back was this leaflet that explained how one's own saliva contains anti biotics. Basically, to cut a two page leaflet down to fit in here.... Lick your finger and put it in your nose, while breathing in. The wetness keeps the nasal passages moist. I personally havent tried it, but according to this remedy page, it seems to work.
