shellyW,
The inner bark of elm is the slippery part. If a product doesn't declare it is inner bark, then you may get the whole bark, inner and outer sections, and it will be less effective.
It is not a teabag, just a powder. Since I have a very sensitive gut, I use 1/2 teaspoon in about 12 oz hot water, first thing when I get up. If you Google it, I think most will use more. You need to experiment so you take the right amount. It is not unpleasant to drink.
I hope you have tried a "food choice" solution too, for your CIC. I didn't mention my additional reliance on the Monash University App's Low-FODMAP foods and portions. I wouldn't be successful without it. However, CIC is not IBS-C. I think I have both.
I have also had to learn to manage everyday stress. For me, the brain and gut "are one."
researchmaven,
Thanx for sharing.
I try to eat so little solid food due to CIC, I have to admit that makes for a crappy diet. I will get out my FODMAP info and review it again. Yes mind brain and gut brain are too related, don't you just hate that. ShelleyW
