Bunty I think the salt is what did it for me too. It is true that we must have salt water in our tissues in order to be hydrated. I use hunza or Sea Salt for the extra minerals. The "table salt" is nothing but pure sodium, but it will work in time.
I also used electronic zapping to help with internal parasites. However, I think the salt and water is a very important key to healing this.
I bathe in salt. I make a sole which I add to my first glass of water in the morning. I salt my food throughout the day with the hunza or pink Sea Salt . And of course, I drink enough water to dispurse all that salt.
