After using big enough dose of this for 2-4 days all bacteria is dead and body can heal inflamed tissue, in a rare case that you would not get well at least you made sure you eliminated all harmful microbes from stomach and can find out what else you need to do, but in most cases body heals well when food disintegrates well in stomach acid. This is the root of the problem pharma industry has hidden from us. All meat eating animals make stomach acid and ruminating ones have bacteria in their stomach to digest plant cellulose. Even vegans don't ever eat the kind of plants (hay) cows, horses and sheep eat. And even beans, lentils and other plant protein needs acid to digest.

Some don't take enough acid from pills either and the problems continue. I once needed 6 per every meal when I was iron deficient. But in 2 days the symptoms all dissappeared and food digested in my stomach so well that I was amazed. No more swelling and no burping, quiet like a sleeping baby. Just needed the normal amount of acid and every bacteria died. When they die nothing makes gas and it's the raising pressure of that gas that forces stomach content up into the esophagus causing reflux. No bacteria should live in stomach but in lack of acid all bacteria from large intestine crawls to stomach and food always contains bacteria too, acid kills them and keeps us safe.
