No, I have not tried Gerson's technique; never heard about it, until reading your question.
But your topic of alkalinization, comes at an interesting time.
I am a veteran and receive most of my medical care at a VA Medical Center. Yesterday, I was there for an appointment.
The receptionist chatted with me, asking me how I was feeling, because I have had to cancel two appointments.
He proceeded to tell me about ALKALINIZING your body,
and the health benefits that staff have seen. Basically, the theory is that cancer cells can't thrive in alkaline, but thrive in acidic
environment. He was suggesting that alkaline drinking water, creates the alkaline environment in your body; destructive cells can't live in it? His method for changing your body from acidic to alkaline, is to use a unit that converts your tap water. The unit treats the tap water, in a different way, than other advertized
The staff member proceeded to give me testimonials, from other staff members, who simply changed to the alkaline water. An optomologist was experiencing pain; but it disappeared after starting the alkaline water. Causation, or coincidence?? I don't know. Another person had experienced severe back problems;
but within a month of drinking the alkaline water, his pain was gone. Is it psychological? I don't know. I do know for a fact, that he DID have back problems, for many months.
After hearing the remarkable testimonials, I later went on the internet, to research the ALKALINE theory. I found mixed beliefs, as to its value. A nutritionist at the Mayo Clinic, indicated that more research is needed, to assess its benefits.
** I just wanted to relate this "story", because I had not known about alkaline versus acidic body environments. And your question, brought this topic up(rapid alkalinization).
I am NOT endorsing any particular treatment, or approach.
The incident at the Veterans Affairs facility, just opened my eyes, to POSSIBLE other options to explore.
After reading your question, I read about the Gerson facility.
I wonder: if a person ate healthy, followed recommended
daily amounts of fruits/vegetables, avoided red meat,etc.--
wouldn't they receive the same benefits as the so called Gerson plan?????
Gerson spokesperson stated that a cancer patient, would need to follow their plan, for AT LEAST 2 YEARS, too achieve overall health improvement. Makes no sense to me! How many cancer patients, have the luxury of HAVING 2 years, to see IF the Gerson program helps?? A cancer patient, with active cancer-like myself, is hoping for an immediate remedy. In my own situation, I see absolutely no value in the Gerson program. I beleive that following a healthy diet and exercise, would achieve the SAME benefits.
In summary, I am skeptical about any "miracle" procedure,
or program. BUT, I do believe that alternative medicine
principles can be beneficial.
