Both my husband and I are extremely sensitive to poison ivy. When my pharmacy was out of my usual remedy, Tecnu (Rash Relief) Spray was suggested. I was skeptical at first, but now I am convinced. This is the best product on the market. Not only did the itching stop immediately, but in two days, my rash has almost completely disappeared... NOTHING has ever worked this well... I will not be going back to my old standby.
