Question for Lapis Re: magnesium chloride

Saw your answer below where you suggest magnesium chloride for liver flush. Will it also loosen the BM and cause the bile ducts to dilate?
I found that when I did my last flush with Epsom Salts , (as before) my bowels stopped moving all together. (See my post in the GB/liver cleanse forum). So I am looking for a good alternative.
