When I get poison ivy I get it scratch bad.  This time I hit it hard as soon as I knew I had it.  Didn’t matter.  scratch It got worse.  I tried just about everything you can think of.  If you are looking for some relief I’ll tell you what to do.  Go to your local drug store and buy some Zanfel.  Is it cheap?  No way.  Does it work?  Oh yes.  Much better than anything else I’ve tried.  If you have any jewelweed available (it grows near poison ivy) get that too.  Break the plant open and rub it on the affected area.  That helps.  But don’t stop there.  Go get some Zanfel.  Follow the directions and you will get relief.
