Your comprehensive book and wonder-working cleansing program have brought me into an exciting new sense of health and well-being. My heartfelt thanks for your marvelous work.

My relative was recently hospitalized twice because of rectal bleeding. She was discharged and the doctors could not do anything for her. I put her on the Special Formula Bulking Agent and the Intestinal Cleansing Formula twice a day and in 3 days, her bleeding stopped. I was amazed.

I can not believe the relief, feeling of lightness and overall well being that I am experiencing now. There were certain problems and gaps in my health that are clearing up. Before this, I could not bring myself to go through the time and trouble required of another colonic irrigation program, but your intestinal cleansing program booklet in my local health food store interested me. I work with seniors and now am beginning to realize that their problems are basically due to stagnant colons.

There is no way anyone could keep me from writing to thank you for developing the Intestinal Cleansing Program. My illness caused me to have extremely sluggish bowel movement for many years even. While on your program, I ate only fruits and vegetables, kept my ‘mildly moderate’ exercise routine, and expelled the intestinal debris of about 25 pounds of superfluous fat, including those dreaded last 10 pounds. This is nothing short of a miracle to me.

Just want to tell you that the Intestinal Cleansing Treatment is the best thing that has happened to me. Since I was 12-14 years of age, I have had problems with my stomach and I tried to live healthily as a vegetarian. But now, I feel cured and the feeling is fantastic.

I’ve lost half a stone, doubled my energy, cleared up my skin and reduced my cellulite on a diet of mashed herbs. My herbal drink’s made me a new woman.

In spite of your admonition not to use your colon cleansing formula in cases of ulcerative colitis, I began the program anyway in an altered, slower regime. I am thrilled to report that it has greatly benefited my condition and I am able to lead a normal life. I do not want to return to my former tortured existence voluntarily.

Your Holistic Horizons products are amazing. I’ve tried M. T. Tri-cleanse, Psyllium Husks, Senna leaf mixture in Professor Egret’s formula and nothing performs like your product. I am a massage therapist with a personal testimony of recovery from bowel disease and Hashimoto’s disease, severe allergies, asthma, and other female problems. I am truly amazed with the significance the colon environment has to do with the body’s well-being.
