I use apple cider vinegar on Chiger bites, poison Ivy, poison oak, and mosquito bites. It burns when applied and I leave it on and do not rinse it off, but the itch goes away rapidly, and the bite/ivy begins to dry up and go away. I apply it two to three days in a row though the itch is gone, because I want any remaining bits of it dead!
@WowwGirl Water and Apple cider vinegar, hmm. Like I said I apply just the apple cider vinegar to the bites directly, I am not into any boiled concoctions LOL.
