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.
