1 liter of warm water and 3 teaspoons of sea salt = The Salt Water Cleanse. I was already planning on doing a cleanse this year, so I decided to give it a shot. My first initial thought was why would anybody do this? I love salt...but not a liter of warm salt water-Gross. That should have stopped me but it didn't. The easiest way to get it down is in 4 cups. The first 2 cups were pretty easy compared to the last 2 which had me dry heaving. Exactly 1 hour after consuming the concoction the cleanse started to work brilliantly. Let's just say it literally clears out your entire intestinal track. Who knew salt could be so good for you.
