Primary focal hyperhidrosis does not cause illness. Basically, you just sweat excessively. Although it is a medical condition, it's not a sign of disease or a drug interaction. People who have it are otherwise healthy. The symptoms of primary focal hyperhidrosis are fairly specific.
Potassium iodide is a component in the electrolyte of dye sensitized solar cells (DSSC) along with iodine. Potassium iodine finds its most important applications in organic synthesis mainly in the preparation of aryl iodides in the Sandmeyer reaction, starting from aryl amines.
THE USE OF IODINE AS AN ANTISEPTIC: Iodide disinfects water at a concentration of 8 ppm. If the water is heavily polluted, use a double dose. A single drop of saturated potassium iodide provides 30 mg of iodine and when added to a liter of water this is 30 mg per 1000 grams, ie. 30 ppm, more than enough to disinfect.
