I like Aromatherapy oil and have found Eucalyptus Oil useful in getting rid of colds. (You can pour a few drops in warm water and inhale or a few drops on a hanky and inhale)
Also, if you have a toothache, put a few drops in warm water and gurgle - it will numb the pain and its better than pain relief tablets. Works immediately.
