If it was that effective the treatment would be available on the NHS.
The NHS, just like hospitals across the US, balk at alternative routes in either treating illness, or teaching people how to prevent illness.
It's big money.
Chemo is big money.
Operations are big money.
For example, if you have stones in your gall bladder, and we all do, 99% of people will wait until they start to hurt and it becomes so much of a problem that they go to the doctor. Then 99% of doctors will recommend an operation.
Those who practice preventative medicine, know that we all get gall stones, so maybe once a year, do a 1 week fast, on the 7th day, at night, before you go to bed, drink a 1/3 of extra virgin olive oil, swish out your mouth with lemon juice, go to sleep. Your gall bladder, having not had to process fats for a week (I do a healthy wheatgrass and Bentonite clay fast), contracts and squeezes out any gallstones you might have the following morning when you go to vacate your bowels. The last time i did this, I counted 16 small stones, in runny, not so offensive poo, having just done a fast.
If you keep up on your health with such easy preventative measures, you don't wind up having to have major ops.
