Calamine
Calamine is either a mixture of zinc oxide (ZnO) with about 0.5% ferric oxide (Fe2O3) or a zinc carbonate compound. It is the main ingredient in calamine lotion and is used as an anti-pruritic (anti-itching agent) to treat conditions such as sunburn, rashes, poison ivy, poison oak, chickenpox, and insect bites and stings. It is also used as a mild antiseptic to prevent infections that can be caused by scratching the affected area, and an astringent to dry weeping or oozing blisters and acne abscesses.
It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.
Medical uses
In a 1992 press release, the U.S. Food and Drug Administration announced that no proof had been submitted showing calamine to be safe for use or effective in treating bug bites, stings, and rashes from poison ivy, poison oak, and poison sumac. The press release listed a total of 415 over the counter (OTC) drug ingredients which the FDA proposed banning for specific uses which were, as of yet, unproven.
Calamine (mineral)
Calamine is a historic name for an ore of zinc. The name calamine was derived from lapis calaminaris, a Latin corruption of Greek cadmia (καδμία), the old name for zinc ores in general. The name of the Belgian town of Kelmis, La Calamine in French, which was home to a zinc mine, comes from that. In the 18th and 19th centuries large ore mines could be found near the German village of Breinigerberg.
During the early 19th century it was discovered that what had been thought to be one ore was actually two distinct minerals:
Although chemically and crystallographically quite distinct, the two minerals exhibit similar massive or botryoidal external form and are not readily distinguished without detailed chemical or physical analysis. The first person to separate the minerals was the British chemist and mineralogist James Smithson in 1803. In the mining industry the term calamine has been historically used to refer to both minerals indiscriminately.

by: CalamineI hold faith
You, you drift in space
Alone
Crossing the big black sky
And a girl could go to rot
Married to an astronaut
But I'm gonna watch and wait
For you to return some day
As you breathe silently on the opposite side
Of the bed
I circle stars you said
Your rockets blare
And you're seven thousand million miles away
You're seven thousand million miles away
You're seven thousand million miles away
And you're seven thousand million miles away
From me
