I have tried this too. And I found that it worked well for me too in the beginning but after a while it stopped. However I had excessive gas and it cured it. I put several drops of the pepperment oil in a bottle of spring water and drank it throughout the day.
I done another enema today with the G.S.E. This seemed to be more effective in getting rid of the odour from my bottom. This tends to leave an odour behind on everything I sit on. However I could still smell the bad odour that I am so accustomed to. I also took some probiotics after my breakie because I have an overgrowth of bacteria in small bowel that is resistant to Antibiotics and everything else Ive tried. Some things work but only for a short length of time but as of yet hasnt been successful in removing the smell altogether.
