Slippery elm as a tea what I do is I mix it with boiling water and put a little cinnamon in it and it kind of tastes like hot chocolate it is very nourishing and it is a demucelent so it will help rehydrate the dehydrated cement like bits which you are passing. It actually has a very pleasant taste. Slightly sweet.
The procedure would be to mix two teaspoons of slippery elm powder in a very small quantity of cold water to make a paste and then to fill the cup with boiling water and stir. If you mix slippery elm directly into boiling water it would be just like putting a tablespoon full of flour in your gravy and stirring it in and hoping for the best. Lumps!
