Poison Ivy - home remedy

Sometimes my posts are precipitated by cleaning up my office or kitchen table and finding scraps pf paper with notes on them. This blog really gives me a good place to file notes. Today I found a note that said "Baking soda and white vinegar - Poison Ivy". I think what it meant was a a good remedy for poison ivy is, making paste of baking soda and white vinegar and putting it on poison ivy. I believe this is something I heard when watching NCIS. I'm happy to say, I have yet to try it. I'm hoping I never get to find out if it really works. However, if you've tried it, please comment and let me know.
