The truth is that the washing out of putrefied material in the large intestine increases the good intestinal flora.
Good bacteria can only breed in a clean environment which has been washed free of putrefaction and its accompanying harmful bacteria. This is why the intestines of a new born baby immediately begin to grow good intestinal flora.
Each time you clean out the putrefying rubbish and make a better environment for the good flora, they start to multiply immediately in their natural media.
It also stands to reason that valuable nutrients can better be absorbed in a clean environment than in a putrefied one. After each treatment you will be offered a capsule to take of good bacteria. If your system is in particular need a course of pro/pre biotics will be advised.
