I agree with the posts of Aaron. I remember a thread a few years ago about oregano oil. A poster came on and proudly declared he had discovered the cure for pouchitis and extolled the benefits of oregano oil. Then around 3 months later there was another post that was “oops, I am not cured after all, it stopped working and I am in really bad shape.” Seen a lot of posts like that over the years. Like Aaron said it’s a constant battle and sometimes treatments stop working. I would certainly not dismiss hydrogen peroxide as a possible treatment, but it needs to be discussed with a medical doctor especially in light of other medications and treatments the patient is taking as well as their overall health.
