oh another thing I tried is the lotrimin, chlortrimazole, yeast products like for athlete's foot and jock itch and they work also but only for a couple of hours. I sprinkled some athlete's foot powder onto an itchy spot and it quits instantly so I can get through the night, also pure with hazel works well temporarily, niacinamide preparations like from The Ordinary also works but very temporarily. The boric acid is best so far
