For Poison Ivy: Mix baking soda and distilled white vinegar to make a paste (will foam up), rub on infected area. It will burn but will dry up the rash in no time. reapply as needed.

I have used baking soda and water and made a paste. It really works I and I could imagine how effective it would be with vinegar added. The biggest thing for me anyways is the relief from the itching especially at night. I found it tolerable at least with no itch. Great advice
