Zinc is one of the oldest metals known to mankind.[1] It is a element] with the symbol Zn and atomic number 30. In some historical and sculptural contexts, it is (or was) known as spelter. It is a metal].
Zinc is most commonly used to [http://ameritrustshield.com/?id=9361 other metals or alloys to make them [http://ameritrustshield.com/?id=9361 resistant. It is also a main constituent of many coins. Zinc also is a element] essential to life.
Zinc lozenges have been claimed to lessen the duration of the common cold, but
- As with more traditional over-the-counter medications, evidence that these products help reduce the duration of colds or lessen symptoms is mostly subjective, says Linda Lambert, cold and flu program director at the National Institute of Allergy and Infectious Disease.[2]
