I am already doing it in addition to bifidum bacteria and aged liquid garlic.
Most colonic centers do this towards the end of their programs, so it's nothing new. They may not use Culterelle, but they definately use probiotics, which are inserted throughout the entire colon "and" they have been doing this for many, many years.
The goal of Culturelle and many (if not all) probiotics is to reach the gastrointestinal tract, which begins from the mouth and ends at the anus...this includes the colon. My nutritionist has spent years researching which probiotics, taken orally, are the most effective at making it to the colon; he also recommends a probiotic enema, which is taken for a two month period as part of his program.
This approach treats you from both ends, which in my humble opinion is the most effective way to repopulate the colon. Finally, probiotics are not harmful to the colon; you may experience gas while the good bacteria is consuming the bad bacteria, but even then it will only last a few days. If you want more information on probiotic enemas you should contact a colonic center (also called colon hydrotherapy).
I have noticed a "big" difference with probiotic enemas. My stools were fully formed through diet but now the texture is better and they don't smell anymore and believe me...they used to smell, really, really, really bad.
No more mercy flushes...lol
