The Lecithin alone will "melt" (bile) gallstones. I found this out when I started taking it. Gone were the stones - all I got out was sludge.
Which kind of begs the question - why go to all that trouble to flush with Epsom Salts ? Or to "flush" at all for that matter?
An easier method might be:
1. Take lecithin to "melt" stones
2. Take lots of fat/fibre regularly to escort the old toxic bile out of the body. E.g. psyllium/olive-oil shakes would do.
