We love this remedy and use it whenever we feel a cold coming on.It came to us from a radio listener in the hills of West Virginia but originated with her grandmother in India.
Grind about half an inch of fresh ginger root into a paste and place in a mug. Add boiling water and "steep" for several minutes. Strain the clear liquid into another mug, sweeten, and sip. Our symptoms start to subside within about twenty minutes.
We drink this in the morning and evening, and our cold usually gets better by the second day.
