Zinc is one of the oldest metals known to mankind.[1] It is a chemical element in the periodic table that has the symbol Zn and atomic number 30. In some historical and sculptural contexts, it is (or was) known as spelter.
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]
