I'm not sure if you need to use boiling water and make it into a gel. No such instructions come with the powder that's bought in 1lb bags.
You get a clue on the recommended dosage indicated on the branded capsule bottles. Most of them call for 3 or 4 caps swallowed down with warm water taken 2-3 times a day. You would have to conclude that 3-4 caps = a little over a teaspoon.
It's obvious that the warm water is to break down the capsule casing quicker and the powder is supposed to form a gel-like substance in your stomach. As on a similar earlier thread to this, one poster said that there is absolutely no need to swallow slippery elm when it has the consistancy of cat vomit (sorry-not my words). His reasoning was probably because there is no reason to 'coat' the upper end of your digestive tract when UC is all down at the very bottom.
Personally, I take a heaped tsp in about 4-5oz of warm juice (pom/acai) at least once a day, though I'm going to increase it to twice a day as I think it's actually helping. I stir it up and drink it down rapidly before it gets time to gel.
