Detoxity and Heal Yourself

"Bowel inflammation is not a runaway problem but a sign that the body has been harmed and is vigorously attempting to detoxity and heal itself, and it will gratefully do so if the causes of disease are discontinued and the biological requisites of health are provided."

David Klein


The Colitis & Crohn’s Health Recovery Center was founded in 1992 by Dr. David Klein, eight years after he permanently overcame eight hellacious years of advanced ulcerative colitis the all-natural way. Dr. Klein and his associate, Zarin Azar, M.D., have guided thousands of colitis, Crohn's and irritable bowel disease sufferers via phone and Skype to new lasting health without medicines.


Inflammatory bowel disease symptoms are signs that the body is vigorously attempting to purify and heal itself. Your body is designed to self-heal – in fact, the symptoms are signs that the body is desperately attempting to detoxify and heal itself. And it will do so when we stop poisoning our bowels, eat our natural diet and take rest. By eliminating toxic foods from our diet and life-sapping drugs, getting complete rest and following simple health-promoting guidelines, everyone can heal up and say good-bye to IBD and IBS! You can and yours can do this, and if you need our help, we are happy to guide you through it.


The self-healing program we teach is based on the health science system known as Natural Hygiene: the science and fine art of health. Natural Hygiene is based upon a correct understanding of human physiology and biology and the body's self-healing requisites. It has been around for 200 years. Hundreds of thousands of people who’ve applied the simple principles of Natural Hygiene have self-healed all kinds of gastrointestinal diseases, even after surgery was recommended. Natural Hygiene has worked in over 99% of the cases with which we have been involved, and it is our privilege to pass this liberating knowledge on to you and yours. There is no other program that works and results in long-lasting health.


Self-healing is the way to go, because nothing can heal the body but the body itself. Most clients heal up within three to eight weeks via the Vegan Healing Diet Plan we teach, and most maintain superior health via the Vegan Post-Healing Diet Plan and our healthful living guidelines. Please don’t miss this opportunity to find out how simple it is to conquer inflammatory bowel disease – the only way: the natural way.


After taking the site tour, please feel free to contact us. The answers to your questions are found in Dr. Klein's best-selling guidebook, Self Healing Colitis & Crohn’s, and we are available to personally guide you to recovery and lasting health. We look forward to serving you and yours!

Mission Statement

Colitis & Crohn’s
Health Recovery Center



Our mission to teach and guide every health seeker within our reach the principles and protocol for self-healing all bowel and digestive orders via an all-natural dietary and lifestyle program. We want the world to learn that the cause and natural healing “cure” for all inflammatory bowel diseases are known and available to you, right now!


Despite contrary medical assertions, almost 100% of all cases of IBD (inflammatory bowel disease), including colitis, Crohn’s and diverticulitis, as well as ulcers, strictures and irritable bowel syndrome (IBS), can be permanently healed by the body without medicines, surgery or any other concocted treatment. Medicines, remedies and surgeries have no healing power and they do not promote health — the can only mask symptoms while evervating the body and leading everyone to an early demise because they are poisons.


We want everyone to understand that Nature (not technology) has the answer to disease. Our highest desire is to make these self-healing truth know to the entire world, and to help you and yours heal and live the healthy and happy life that is your birthright.
