Over a six-month period in 2017, Dr. David Klein guided surgeon Richard D. Klein, MD (no relation) of Florida from ulcerative colitis to vibrant health with no more medications. Dr. Richard Klein had been sick for three years and took several drugs, including an immunosuppressant. Dr. Richard Klein wrote the following in an email on July 5th, 2018: “All is good here. I am doing super well and have had no symptoms. I am still following your advice. Life is great. I can’t thank you enough for saving my life. I would be more than happy to talk to whomever you send my way. Please give them my contact info.”

“Over years of practice I have observed the pain and suffering of my colitis patients who are on conventional medical therapy. High dosages of immuno-suppressants, such as prednisone and like products, are commonly given, resulting in effects ranging from serious to life-threatening. This only suppresses the symptoms temporarily. Disease typically later manifests again, with even more severe and bothersome symptoms. I was very impressed with David’s Natural Hygiene approach to healing ulcerative colitis and Crohn’s disease, outlined in his book Self Healing Colitis & Crohn’s. Healthy since 1984 after a severe 8-year bout with ulcerative colitis, he himself is living proof that his program works. I support his approach one hundred percent and believe it is the only way of healing colitis and almost all other health problems, and, therefore, I recommend it to every one of my clients. The results are always good because the diet is our natural biological diet, is nontoxic, nutritionally superior, satisfying, and since only the body’s own wisdom can heal itself, the Natural Hygiene approach makes perfect sense.”

“David has exhibited uncommon dedication to helping people become well over the twelve years I have known him. Like David, in my practice I see long-lasting results when a patient embraces a detoxification program and adopts a healthful lifestyle with a vegan diet. David’s recovery from severe ulcerative colitis, his studies in nutrition and physiology, and his consistent results have given him unique expertise in self-healing. In Self Healing Colitis & Crohn’s we have the blueprint for overcoming IBD.”

Terri Su, M.D. Santa Rosa, California


“I know of no physician who is not reluctant to prescribe corticosteroids or advise surgery for the treatment of inflammatory bowel disease, and yet they are the mainstays of traditional therapy. In Self Healing Colitis & Crohn’s is a clear and detailed healing plan that eschews both and offers a program based on the author’s personal experience and extensive research. It deserves our grateful attention.”

Robert F. Lally Jr., M.D. Friday Harbor, Washington


“Ulcerative colitis is a debilitating disease that has long been regarded as untreatable. For many patients, the illness has therefore meant considerable suffering and the end of a normally functioning life. Thanks to David Klein, this need no longer be true. Self Healing Colitis & Crohn’s is an insightful and compassionate book by a leading nutritionist who suffered from this crippling disease, cured himself and has since gone on to become a pioneer in effective nutritional counseling. It is a must read for anyone who wants an active role in restoring 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


“Dr. David Klein’s Self Healing Colitis & Crohn’s book demystifies the secrets of the innate natural health processes, by which the body possesses the power to heal itself. A HygioPhysician and former victim of ulcerative colitis, Dr. Klein is the leading modern-day pioneer and authority on the self-healing principles of colitis and Crohn’s disease. He is living proof that the body can cure itself and maintain its natural, pristine health when the causes of disease are removed and it is allowed to perform its magical healing-dance of life.”

Paul Fanny, Ph.D., H.D. President of the University of Natural Health Hookset, New Hampshire


“When it comes to self-healing, Dr. David Klein has been there and done that, like very few have ever done. His depth of understanding of the issues involved in the causes and healing of bowel disease is only matched by his compassion for current sufferers. There is no reason for anyone else to write on this topic because Dave has already perfected the healing process. Like the law of gravity, his program works first time, every time. Put it to work for you and suffer no more.”
