All three! and more.....I am taking one teaspoon of sole solution daily, diluted in a tall glass of pure water. I cook with the granulated form of it, and I bathe in it. Also brush my teeth with it, it's wonderful for the teeth and gums. The research claims that swishing in the mouth 3 minutes daily will actually restore any decay to health!
It's actually one of the most amazing additions to my regimen I have ever added. So complete....
