*The Gerson Therapy Definition and Facts
*Gerson Therapy Definition and Facts Written by Charles P. Davis, MD, PhD.
- Gerson Therapy is a method used by some individuals to treat cancer and other diseases.
- Gerson Therapy and is based on diet, supplementation (minerals, enzymes and other dietary factors), and detoxification (including enemas and other treatments).
- Gerson therapy was developed by Dr. Max B. Gerson initially to treat migraine headaches, and later, tuberculosis, and other conditions including cancer.
- Therapy requires many details to be followed precisely. Here are examples.
- Side effects of the therapy may include changes in chemicals (for example electrolytes and/or fluids) that, in some individuals, can lead to dysfunction of organ systems such as the muscles or heart, or even death.
- There have been no results of laboratory animal studies published in scientific journals about the Gerson Therapy.
- The National Cancer Institute reviewed the records of 60 patients treated by Dr. Gerson and decided Gerson Therapy did not prove to provide any benefit to the patient’s health. In contrast, one or two other small clinical studies have suggested that perhaps clinical trials of the therapy be done.
- To date, the Gerson therapy has not been approved by the FDA for use as a treatment for cancers or for any other disease.
- Individuals are urged to discuss the use of this therapy with their healthcare provider before beginning its use.
What is the Gerson Therapy?
The Gerson therapy has been used by some people to treat cancer and other diseases. It is based on the role of minerals, enzymes, and other dietary factors. There are 3 key parts to the therapy:
- Diet: Organic fruits, vegetables, and whole grains to give the body plenty of vitamins, minerals, enzymes, and other nutrients. The fruits and vegetables are low in sodium (salt) and high in potassium.
- Supplementation: The addition of certain substances to the diet to help correct cell metabolism (the chemical changes that take place in a cell to make energy and basic materials needed for the body's life processes).
- Detoxification: Treatments, including enemas, to remove toxic (harmful) substances from the body.
Who Discovered the Gerson Therapy? What Diseases Does Treat?
The Gerson therapy was named after Dr. Max B. Gerson (1881-1959), who first used it to treat his migraine headaches. In the 1930's, Dr. Gerson’s therapy became known to the public as a treatment for a type of tuberculosis (TB). The Gerson therapy was later used to treat other conditions, including cancer.
How Is the Gerson Therapy Useful in Treating Cancer?
The Gerson therapy is based on the idea that cancer develops when there are changes in cell metabolism because of the buildup of toxic substances in the body. Dr. Gerson said the disease process makes more toxins and the liver becomes overworked. According to Dr. Gerson, people with cancer also have too much sodium and too little potassium in the cells in their bodies, which causes tissue damage and weakened organs.
The goal of the Gerson therapy is to restore the body to health by repairing the liver and returning the metabolism to its normal state. According to Dr. Gerson, this can be done by removing toxins from the body and building up the immune system with diet and supplements. The enemas are said to widen the bile ducts of the liver so toxins can be released. According to Dr. Gerson, the liver is further overworked as the treatment regimen breaks down cancer cells and rids the body of toxins. Pancreatic enzymes are given to decrease the demands on the weakened liver and pancreas to make enzymes for digestion. An organic diet and nutritional supplements are used to boost the immune system and support the body as the regimen cleans the body of toxins. Foods low in sodium and high in potassium are said to help correct the tissue damage caused by having too much sodium in the cells.

How Does the Gerson Therapy Work?
The Gerson therapy requires that the many details of its treatment plan be followed exactly. Some key parts of the regimen include the following:
- Drinking 13 glasses of juice a day. The juice must be freshly made from organic fruits and vegetables and be taken once every hour.
- Eating vegetarian meals of organically grown fruits, vegetables, and whole grains.
- Taking a number of supplements, including:
- Lugol's Solution (potassium iodide, iodine, and water).
- Coenzyme Q10 injected with vitamin B12. (The original regimen used crude liver extract instead of coenzyme Q10.)
- Vitamins A, C, and B3 (niacin).
- Flaxseed oil.
- Pancreatic enzymes.
- Pepsin (a stomach enzyme).
- Taking coffee or chamomile enemas regularly to remove toxins from the body.
- Preparing food without salt, spices, or oils, and without using aluminum cookware or utensils.
What Are the Side Effects or Risks the Gerson Therapy?
Reports of three deaths that may be related to coffee enemas have been published. Taking too many enemas of any kind can cause changes in normal blood chemistry, chemicals that occur naturally in the body and keep the muscles, heart, and other organs working properly.
Have Laboratory or Animal Studies Been Conducted Using the Gerson Therapy?
No results of laboratory or animal studies have been published in scientific journals.
Have Any Clinical Trials Been Done on the Gerson Therapy?
Most of the published information on the use of the Gerson therapy reports on retrospective studies (reviews of past cases). Dr. Gerson published case histories (detailed reports of the diagnosis, treatment, and follow-up of individual patients) of 50 of his patients. He treated several different types of cancer in his practice. The reports include Dr. Gerson's notes, with some X-rays of the patients over time. The follow-up was contact with patients by mail or phone and included anecdotal reports (incomplete descriptions of the medical and treatment histories of one or more patients).
In 1947 and 1959, the National Cancer Institute (NCI) reviewed the cases of a total of 60 patients treated by Dr. Gerson. The NCI found that the available information did not prove the regimen had benefit.
The following studies of the Gerson therapy were published:
- In 1983-1984, a retrospective study of 38 patients treated with the Gerson therapy was done. Medical records were not available to the authors of the study; information came from patient interviews. These case reviews did not provide information that supports the usefulness of the Gerson therapy for treating cancer.
- In 1990, a study of a diet regimen similar to the Gerson therapy was done in Austria. The patients received standard treatment along with the special diet. The authors of the study reported that the diet appeared to help patients live longer than usual and have fewer side effects. The authors said it needed further study.
- In 1995, the Gerson Research Organization did a retrospective study of their melanoma patients who were treated with the Gerson therapy. The study reported that patients who had stage III or stage IV melanoma lived longer than usual for patients with these stages of melanoma. There have been no clinical trials that support the findings of this retrospective study.
- A case review of 6 patients with metastatic cancer who used the Gerson therapy reported that the regimen helped patients in some ways, both physically and psychologically. Based on these results, the reviewers recommended that clinical trials of the Gerson therapy be conducted.
Is the Gerson Therapy Approved by the FDA for Use as a Cancer Treatment in the US?
The Gerson therapy has not been approved by the FDA for use as a treatment for cancer or any other disease.
For most cancer patients, nutrition guidelines include eating a well-balanced diet with plenty of fruits, vegetables, and whole-grain products. However, general guidelines such as these may have to be changed to meet the specific needs of an individual patient. Patients should talk with their health care providers about an appropriate diet to follow.
