I am trying a natural alternative to help heal my psoriasis. The book (by John O. A. Pagano) recommends using high colonics or home enemas during the first couple months of dieting to help cleanse the colon. Since this book was originally published in 1991, I'm not sure how far along products such as Colonix or Bowtrol were (or if they even existed at all) and Dr. Pagano does not mention them in the book. From what I've read on the Internet, however, it appears to me these products have the same effect as a high colonic, and may even be safer and more effective.
