Is it possible to combine neem, berberine and allicin during IMO herbal treatment?

Yes, you can combine these herbs in IMO therapy. However, despite the positive effects, herbal therapy should be treated rather supportively. I also encourage you to change your eating habits, preferably under the supervision of a dietitian. MZ also recommends the low FODMAP diet as a diet indicated in intestinal ailments. It consists in temporarily limiting the consumed products by eliminating from the diet those that have a high level of FODMAPs (fermenting oligo- and monosaccharides and polyols): https://pacjent.gov.pl/diety/low-fodmap-dieta-w-jelicie-nadwrazliwym The gdziepolek.pl service also allows you to obtain a teleconsultation with an appropriate specialist: https://www.gdziepolek.pl/telekonsultacja/z-dietetykiem In this situation, I encourage you to make an appointment with a gastroenterologist who will adjust the treatment according to your current clinical condition.
