Available scientific evidence does not support claims that Gerson therapy is effective in treating cancer, and the principles behind it are not widely accepted by the scientific and medical communities. It is not approved for use in the United States. Gerson therapy can be dangerous. Coffee enemas have been associated with serious infections, dehydration, constipation, colitis (inflammation of the colon), electrolyte imbalances, and even death.

In 1945, Gerson published a preliminary report of his results in treating cancer in the Review of Gastroenterology. The National Cancer Institute and New York County Medical Society examined records of his patients and found no evidence that the method was effective against cancer.

The treatment method has evolved slightly over the years; for example, it once required drinking raw calves’ liver extract, but that was removed after the risks of raw liver were understood. An injectable liver extract was substituted.

Serious illness and death have rarely occurred from some parts of the treatment, such as the coffee enemas, which remove potassium from the body and can lead to electrolyte imbalances. Continued home use of enemas may cause the colon's normal function to weaken, worsening constipation problems and colitis. Some metabolic diets used in combination with enemas cause dehydration. There is at least one report of hot enemas causing serious problems such as burns, scarring, and rectal perforation (holes).

Serious infections may result from poorly administered liver extracts. Thyroid supplements may cause severe bleeding in patients who have cancer that has spread to the liver.
