[Margaret Pilkington]

Flashy is right....menthol crystals are cheap and effective.....you only need two or three crystals in about an inch of boiling water in a cheap plastic jug.
Put your nose into the pouring spout and close the opening of the jug with your mouth and lower half of your face....this method of inhaling mentholated steam means that it doesn't sting your eyes.
If you repeat this every couple of hours during the day, it will clear your head and keep your nose from getting bunged up.
Steam also kills the bugs in your nose and throat.
