Hi 110549,

You've written a very interesting post here.  I like the remedies you recommend. Thanks.

Here's a little more information about one of the main chemical compound responsible for the smell of flatus and fecal breath, and that is methanethiol (also known as methyl mercaptan). 

Methanethiol (also known as methyl mercaptan) is a colorless gas with a smell like rotten cabbage . It is a natural substance found in the blood , brain, and other animal as well as plant tissues... It is also one of the main chemicals responsible for bad breath and the smell of flatus. The chemical formula for methanethiol is CH3SH ; it is classified as a thiol.

Here's an excerpt from an abstract of an article entitled, Biofilms and the tongue:  Therapeutical approaches for the control of halitosis, 

...although the dorsum of the tongue seems to harbour one of the most complex microbiological niches in human ecology, the knowledge of the role of tongue flora in health and disease is also very limited. Similarly, the nature of the tongue coating and the factors that influence its development and composition are almost unknown. The interest in the study of the tongue niche has increased in recent years due to its association with oral halitosis and to its role as a suitable reservoir for periodontal pathogens. The structure of the tongue favours a unique and complex bacterial biofilm, in which periodontal pathogens are frequently found. However, little is known about how to control this bacterial niche, and factors affecting tongue coating composition and aspect are not fully understood. Studies available on the influence of mechanical or antimicrobial approaches against tongue biofilm are very limited. Mechanical treatments showed a transient reduction in halitosis-related variables but were limited in time. Different antimicrobials agents have been evaluated: chlorhexidine, chlorine dioxide, metal ions, triclosan, formulations containing essential oils , and hydrogen peroxide... http://www.springerlink.com/content/kklgyab4e7t42m63/?p=71477f106169446f98310...

None of those things work. I tried them all for more than 25 years trying everything that had to do with leaky gut and anything that had to do with my problem and looking for an answer and isolating my self and wanting to kill myself. I even remember when I was in second grade I was reading to my mother and a friend was next to me and said, "does she always smell like that?" and so many shamefuill situations that I jus wanted to get out of this world. That is how bad my situation was. I know what these people are going through, just by needing more stomach acid to help digest the food plus enzymes and probiotics and just a mouthwash with Hydrogene Peroxide. After so long looking for an answerI found it and want to share it with so many people who are going through the shame that brings the situation. My breath and my body odor reached places before I did. They could be smelled a mile away until I tried this routine: I have suffered so much with this problem that now that I found the root of the problem and the cure I want to share it with all the people who have the same problem and are desperate to find a solution. Please, follow these steps and your body and breath will stop smelling. 1- Have a colon and whole body cleanse (the kid is sold at every place they sell vitamins). 2- Take zinc pills. They will stop the smell right away, but will not go to the root of the problem. 3- Make gargles with Hydrogen peroxide. All the old bacteria will die and the bad smell will be gone leaving you with a fresh breath, but the root of the problem is still there. Very important step: 4-Take Vitamin (B6) Pyridoxine Hydrochloride, and Multi-Enzymes and Probiotics Formula. I use Rexal, sold at Walmart. It works perfectly, but you can go to your regular drugstore and buy any Formula of enzymes and probiotics. Step # 4 Since the body odor comes from lack of enzymes and stomach acids to digest proteins and fats, that will go to the intestine without being digested and into the boodstream along with fecal matters that make the body smell, you need to take Vitamin B6 and enzymes plus probiotics as directed by the manufacturer to help you digest your food and the problem is solved. . If you only have bad breath, and it continues after following these steps, probably it comes from cavities. Visit your dentist. If you have crowns, probably the cavity is under the crown.
