The world leaders in guiding clients with colitis, Crohn’s, IBS and other bowel disorders to disease-free health without medicines since 1993.

Detoxify, Nutrify and Heal Yourself!

"Bowel inflammation is not a runaway problem, but a sign that the body has become toxic and it is vigorously attempting to detoxify and heal its damaged tissues. The bowel will begin healing as soon as the causes of disease (primarily toxic, unnatural foods and medicines) are discontinued and our natural dietary healing program is implemented. I did this myself in 1984, and now it's my mission to help you and yours heal and attain perfect lasting health."

-David Klein, Ph.D., Naturorthopathic Doctor

Our Life-Saving Diet Plan

"Ninety-nine percent of our thousands of clients have healed all types of inflammatory bowel diseases via the Vegan Healing Diet Plan we teach. It is a specialized, perfectly digestible version of our natural biological diet. It results in lasting vibrant health. This medically-endorsed, nutritionally complete, life-saving diet plan is provided in Dr. Klein's Self Healing Colitis & Crohn's and Digestion Perfection guidebooks."

-David Klein, Ph.D., Naturorthopathic Doctor

The Blueprint for Healing IBD & IBS

"Self Healing Colitis & Crohn's is an insightful and compassionate book by a leading nutritional doctor who suffered from this crippling disease, healed himself and has since gone on to become a pioneer in effective nutritional counseling. It is a must-read for anyone who wants to restore himself or herself to health."

-A. William Menzin, M.D., M.Sc. M.P.H.
Department of Psychiatry, Harvard Medical School (retired), Former Consultant to the World Health Organization (WHO), Princeton, New Jersey

Don't Live With IBD!
The Body Can Heal It!

David Klein

Dr. David Klein and Dr. Zarin Azar are the world leaders in guiding clients with colitis, Crohn’s, IBS and other bowel disorders to disease-free health without medicines since 1993. Ninety-nine percent of our clients heal completely via the Vegan Healing Diet Plan we teach.

All inflammatory bowel diseases are healable via our natural, medically-endorsed dietary healing program. When the causes of IBD—toxic diets and lifestyle stress—are replaced with our specialized natural diet and a period of rest, detoxification and healing occur.

The Colitis & Crohn’s Health Recovery Center was founded in 1992 by Dr. David Klein, eight years after he permanently overcame eight ruinous years of ulcerative colitis the all-natural way. Dr. Klein and his associate, Zarin Azar, M.D., a gastroenterologist and hepatologist, 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 is 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 enervating 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.
