As is often the case when alternative treatments prevail, Dr. Gerson became the object of derision and suspicion by critics in the medical community. It didn't matter that his results had been independently verified in the hospital study, or that sanatoriums were reporting great success treating their patients with his diet therapy. His critics accused him of falsifying data, saying Gerson's patients had never suffered from lupus vulgaris.
During this time a woman with an advanced case of inoperable cancer of the bile duct heard of Gerson's success in treating both tuberculosis and arthritis. She asked Dr. Gerson for help, but he didn't want to treat her, fearing an attempt at cancer treatment would increase the professional backlash. But the woman insisted, telling him she would sign a statement holding him harmless if the treatment did not work. She finally convinced him. After she was cured, she brought two relatives with cancer to him for treatment, whom he also cured.
Dr. Gerson decided to appease his critics by conducting a new study. No patient would be included in the study unless two doctors independently confirmed the diagnosis prior to treatment. Unfortunately, Gerson's research was left behind when he fled Nazi Germany.
Though Dr. Gerson was the first to say he didn't know why the treatment worked on
those first three cancer patients, he was intrigued by the possibility of successfully treating cancer. In Vienna he attempted to treat six more cancer patients, without success. In Paris he treated seven, with three successes.
When he immigrated to the United States and became licensed to practice, he again began treating cancer patients. Gerson said, “On the one side, the knife of the AMA was at my throat and on my back. I had only terminal cases. If I had not saved them, my clinic would have been a death house. Some of the cases were brought on stretchers. They couldn't walk. They could no longer eat. It was very, very difficult. So, I really had to work out a treatment that could help these far advanced cases.”
As he continued to refine his treatment, he came to the conclusion that the disease process is essentially the same in all degenerative diseases.
He believed the digestive tract to be the most important part of our bodies. If digestion does not work properly, the body and its other organs are not properly nourished. And if digestion does not work properly, all waste products—toxins and poisons—are not eliminated. Instead they accumulate in our bodies. If the liver is overwhelmed, good health is impossible.
During the Gerson treatment, the body is flooded with nutrients, oxidizing enzymes, and potassium. No added salt or
fats other than flaxseed oil are allowed. Freshly pressed organic fruit and vegetable juices are given hourly. Coffee enemas are administered several times daily. As tumors die, the mass of dead cells are absorbed. They flood the bloodstream. Without proper detoxification, poisons accumulate, and patients, even those whose cancer has been eradicated, will die. Coffee enemas aid in detoxification and decrease pain.
Gerson believed our health begins with the quality of the soil in which our food is grown. “Our soil must be normal, no artificial fertilizers should be used, no poisons, no sprays which go into the soil and poison it. Whatever grows on a poisoned soil carries poison, too. And that is our food, our fruit and vegetables. I am convinced that the soil is our external metabolism. It is not really far removed from our bodies. We depend on it. But our modern food, the "normal" food people eat is bottled, poisoned, canned, color added, powdered, frozen, dipped in acids, sprayed-no longer normal. We no longer have living, normal food, our food and drink is a mass of dead, poisoned material, and one cannot cure very sick people by adding poisons to their systems.”
