If you want to do a colon cleanse, these are my favorite books on that topic, with links to Amazon to buy them:
Bernard Jensen’s Dr. Jensen’s Guide to Better Bowel Care: A Complete Program for Tissue Cleansing Through Bowel Management is a must-read for anyone willing to face the fact that the average person is carrying 10 lbs. of impacted fecal material. The last 25 pages are color photos of what those who undergo a colon cleanse actually eliminate, and I am warning you that it may turn your stomach. However, it may also be just the motivation you need to get rid of it. Great information is in this book from an early pioneer in health, healing, nutrition, and cleansing. Dr. Jensen is a man who lived, well into his 90′s, what he preached.
Richard Anderson’s Cleanse & Purify Thyself: Book 1 and 2. This naturopathic doctor was on a quest (because of his own desperate health situation) to find exactly the right herbs for a thorough intestinal and parasite cleanse. He walked around in the mountains for months, with a friend, experimenting. The commercial products I enthusiastically endorse (because I have personally experienced the promised results, as well as studied the methodology) that resulted from Dr. Anderson’s quest are the Arise & Shine cleanse, found in health food stores and at www.ariseandshine.com. The products are high quality, and the cleanse truly delivers a comprehensive cleanup of the entire gastrointestinal tract. Other cleanses I researched are lightweight compared to this one, and the nutritional support is astonishing: I lived my normal, crazy-busy soccer mom/professor/entrepreneur life the entire time I did the regimen, with plenty of energy. These books, too, contain graphic photos of actual eliminations from cleanse patients.
