9. Licorice root
Like ginger, licorice is an expectorant, meaning that it helps expel mucus from the throat and lungs. It is available in its raw form at most health food stores or at shops that sell specialty spices. When taken internally, licorice soothes inflamed tissue. cleanses the liver, and remoisturizes from the inside out. Boil a piece of the root for 3 minutes, then let it steep until it has cooled enough to drink. Strain and add honey to taste.
