That won't work for her if the smell is not coming from her mouth. If the problem is from the rectal area gargling with peroxide won't help much. The probiotics and enzymes may contribute to the healing process because it's going to the large and small colon area They should make sure that there are more strains in the probiotics and not just Lactbacillus acidolphilus because that mostly digestes in the small colon. You also need to attack the large colon as well withprobiotic strains which is where the food is broken down into feces.I never used Align but I have used Acidolphilis with extra strains with bifidus and other strains (for the large intestines) which did help.
