The author explains well the more than important role in our intestines, causes intestinal damage, how we share our daily poisoning fouls. The second part is devoted to natural solutions to regain undamaged bowel (enema, colonic irrigation, different cures ...) and then some tips good for intestinal flora and how to reseed it.
For people new to the subject and who wish to book a little more accessible to all, I recommend their "health through bowel" Health through the bowel, which reads very quickly and that sums the subject, with the addition of very small explanatory diagrams. As for those of you who want a manual for enemas, there are none in these two books, but if you go on the site Xantis.fr you will find the famous rectal shower and if you go on "kit" and "how to", and although you have all the schemes in question.
