I’ve offered remedies to soothe mosquito bites in past posts, well, here’s another: salt. To stop the itch, dampen a 1/4 teaspoon of salt with a drop or 2 of water. Rub this mixture over the bite. The itch should stop within 40 seconds because the salt breaks down the inflammatory proteins that are produced by our bodies in response to the bite. A bonus is that it will kill any germs that are trying to invade your damaged skin from the bite.
