I was guessing before but here are the actual instructions. Info from John Toomey Consulting.

Start with a 2lt jug. Place a heaped dessert spoon of Celtic Sea Salt in the jug and then add a cup of hot water. Stir till the salt has dissolved into solution. Fill the jug to the top with warm water.

Now, sit in a comfotable location and drink the solution. You should get it all into your body within 25-30 minutes. If it works, you should visit the toilet 5-6 times.

This should be done at the start of the day and you should make sure that you have easy access to a toilet. Continue drinking water once the solution is in your body.

If the solution does not have an impact you will know that your bowel is not in a very healthy state and it may be worth visiting a Colonic Hydrotherapy specialist or a Naturopath.

To help promote the friendly bacteria in you bowel, drink a glass of warm water with the juice of a lemon every morning before you eat.

This should not be attempted if you have a history of high blood pressure or heart problems. Contact a Naturopath for guidance.

Celtic sea salt can be bought from Health Food shops.
