You only need 2 tsp of Sea Salt . If you read Mr. Burrows book on The Master Cleanse the salt water flush recipe is in it. I started doing this flush over 7 years ago and have seen countless videos and websites and they have all recommended 2 teaspoons. Nevertheless, maybe the more salt the more effective. However, I believe drinking too much of the salt can make you nauseous. I have felt like that twice when I didn't have my teaspoon measuring spoon and used other spoons. Anyway, it works with 2 teaspoons as well.
