Zinc Edges Out Chicken Soup

From The New York Times by Tara Parker-Pope: Scientists still haven’t discovered a cure for the common cold, but researchers now say zinc may be the next best thing.

A sweeping new review of the medical research on zinc shows that sniffing, sneezing, coughing and stuffy-headed cold sufferers finally have a better option than just tissue and chicken soup. When taken within 24 hours of the first runny nose or sore throat, zinc lozenges, tablets or syrups can cut colds short by an average of a day or more and sharply reduce the severity of symptoms, according to the Cochrane Database of Systematic Reviews, a respected medical clearinghouse.

In some of the cited studies, the benefits of zinc were significant. A March 2008 report in The Journal of Infectious Diseases, for example, found that zinc lozenges cut the duration of colds to four days from seven days, and reduced coughing to two days from five.

While it’s not certain how the mineral curbs colds, it appears to have antiviral properties that prevent the cold virus from replicating or attaching to nasal membranes.
