Sea Salt is salt, Epsom Salts is Magnesium. It's confusing, but any necessary mineral that has a charge is called a salt! So when we say the body's salts, we mean sodium, potassium, magnesium, calcium, phosphorous.

Epsom Salts are used in Liver Flushes because they relax bile ducts, guarranteeing a pain-free flush, altho i've never had any pain even without them so I don't bother with them.

The salt water flush is an intestinal flush, you don't need to worry about the bile ducts, you need to worry about how to keep the water suspended in the tract w/o getting absorbed. That's what salt will do but magnesium will not necessarily do as well.

So happy flushing! :)
