Gerson Therapy (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - History

continued...

Controversy about the efficacy of the Gerson therapy continued throughout Gerson's life. In 1946 and 1949, two articles in the Journal of the American Medical Association concluded that the treatment was of no value.[9,10] The National Cancer Institute (NCI) reviewed Gerson's data from ten case histories in 1947 and 50 case histories in 1959. NCI concluded that in most cases, basic criteria for evaluating clinical benefit were not met. NCI concluded that the data demonstrated no benefit.[2] In 1972, the American Cancer Society (ACS) published a statement summarizing the negative assessments of Gerson's treatment.[11] Another statement published by ACS in 1991 concerned various "metabolic therapies" (defined as treatments that depend on changing metabolism through diet, enemas, and supplements given at clinics in Tijuana, Mexico) and reemphasized the lack of scientific evidence on the efficacy of the Gerson regimen.[12]

Gerson died in 1959, leaving behind no systematic way to continue offering his treatment. His malpractice insurance had been canceled in 1953, and in 1958 he was suspended for 2 years from the New York County Medical Society.[11] In 1977, his daughter, Charlotte Gerson Straus, who had continued to lecture widely about the Gerson therapy, cofounded the Gerson Institute with Norman Fritz. Located in San Diego, the Gerson Institute does not own or operate treatment facilities but maintains a licensing program for treatment centers such as the Centro Hospitalario Internacional Pacifico and Mexico's Center for Integrative Medicine and the Gerson Hospital (CHIPSA) in Baja California, Mexico. CHIPSA refers to Max Gerson as the founder of "immunonutrition," their term for Gerson's idea of cleansing the body while building up the immune system through diet and supplementation.
