My advice to you is to read everything that Dr. borody has written at the website I mentioned earlier. Get Kelly Karpa's Book. Her baby boy almost died from a long standing intestinal bacteria. She lists some natural protocals in her book. The problem with many herbal remedies and pharmaceuticals is they only make matters worse because the kill good and bad bacteria. She mentions Questran, which binds up bacterial toxins in the gut. aLso florastor, a friendly yeast may be helpful. Human Probiotic Infusion to my mind may be the ultimate cure. This is mentioned in her book. Dr. Borody does this procedure. They put you on a Antibiotic which clears the intestinal tract of all bacteria, both good and bad, then repopulate the gut with probiotic from fecal matter fom a healthy donor. It has a cure rate of 95 percent.
