Can poison ivy plant be killed by using table salt dissolved in water?

I've heard of people using epson salt before, but personally I've never tried it.

I just recently cured a case of poison ivy last weekend with a combination of treating it with bleach and water and then calomine lotion. If you don't have any calomine lotion, I would try my best to buy some right away, but if you really can't epson salt sounds like it would work over time, maybe a little less effectively at first though (since it is a home remedy).
