Flushes since I needed surgery according to the doctor and I did not want to. Later I found out about all the other things. But as long as as you don't have constipation you can do the flush. The Epsom Salts (=magnesium sulfate, not salt) will clean your intestines for the flush and relaxes the bile ducts.
In between you can do the bowel cleaning you just skip on the 2 days you do the flush. The Bowel Cleanses with the magnesium oxides are short and you can do it between the flushing.
