“Calamine” is an early name that covered the zinc minerals Smithsonite, Hydrozincite and Hemimorphite. In today’s parlance is referes to an astringent made from zinc carbonate or zinc oxide, usually used in lotion form to treat skin problems that cause itching or discomfort. Ti be more complete, Calamine is a mixture of zinc oxide (ZnO) with about 0.5% iron(III) oxide (Fe2O3). It is the main ingredient in calamine lotion which is used as an anti-itching agent to treat mild pruritic conditions such as poison ivy, sunburn, eczema, rashes, chickenpox, insect bites and stings. It is also used as a topical antiseptic to prevent infections that can be caused by scratching the affected area, and an astringent for dry weeping or oozing blisters and acne abscesses.
