This comes from The Master Cleanse and I have used it to clean out my intestines pre and post flush. The Salt water (sodium cloride) doesn't relax the biliary ducts like the Epsom Salts so you might need to take at lest one dose of Epsom Salts (magnesium sulfate) before the flush so the stones can get through the ducts more easily.
SALT WATER FLUSH:
Start each morning with 1 quart of water and 2 tsp. natural unrefined Sea Salt (NOT iodized or refined salt). Mix well and chug down. It's nice to massage the colon as well. This will clean your colon well. Or get an enema every day. coffee enema also works wonders!
