When your talking oxypowder and enzymes and what ever P&B shakes are these things most likely harm the intestines, I know at least the first 2 do. The LBB works great for everyone by its self, it can't fail, it is impossible to fail anyone that takes it correctly.
Naturally the key word is correctly. Those mixing in a variety if things in a mix/mess I have no clue what all their problems actually are, they could be drinking toxic drinks, toxic foods, have dental metals, etc. etc. and then expect a few herbal captures to be the miracle cure.
For these reasons, I suggest people read BOOK I, it doesn't even use an herb and works for 100% of the population, so adding a few safe herbs only makes it better, you can't go wrong.
What does go wrong is when people choose their way and then wonders what went wrong, the best I can say is read the news letters, the books and decide if you want to mix allot of products and methods together hoping it will be better. You never know till you try.
I know Dr. Christopher's methods and Book I methods do not fail, ket word they do what the authors suggested.
For starters I suggest you read the colon book, for $7.95 it explains many of the problems with the bowels.
The LBB is taken more when the bowel is liquid, not less. Using toxic products with this is not my ideal of making it better. Much of the garbage advertized by web sites is toxic and people spend millions of $$$$$ on such garbage.
