Q. Some time ago I had a horrible coughing fit at my bank. The teller, an Indian woman, motioned for me and handed me a couple pieces of candied ginger from her purse. It worked immediately and now I keep some handy for anyone needing it to quell a cough.
A. What a tasty cough remedy! Research dating back to 1984 shows that a compound in ginger, (6)-shogaol, is at least as effective as a codeine compound in fighting a cough (Journal of Pharmacobio-Dynamics, Nov., 1984). More recently, scientists have confirmed that this compound can also fight fever, pain and inflammation (Immunopharmacology and Immunotoxicology, Aug., 2013).
We have frequently recommended ginger tea or honey as a cough remedy for children, rather than drugstore remedies. It seems that candied ginger combines some of the properties of both, and is highly portable besides. Just as with cough drops, though, the sweetening can act like candy and should be taken in moderation.
