I have read Dr. Quillin's book "Beating Cancer With Nutrition" and I must admit that through my research on the topic of cancer "helps" he has included almost all of the substances that tend to show promise in fighting cancer. My biggest question would be what is the source of the ingredients, ie natural or synthetic? To this no info is given. As to the cost they are right in saying it will cost you a lot more if you try to purchase the ingredients one by one. Another question I would have is about the synergy of the ingredients being taken all together at once. It is well documented that you do NOT take Vitamin E with Iron. Plus I wonder if Dr. Quillin has any studies to show the benefits of taking this formula which he himself created and sells, with surprisingly is not mentioned in the book.
In short you might want to see Dr. Ralph Moss' site for more info on alternative healing. What I have found is that 10,000mg of vitamin C has a strong backing along with AHCC (mushroom extracts) and the "dreaded" laetrile". All have been shown to help fight cancer in numerous studies. Bovine cartilage has shown to be very helpful though I am not sure as to any clinical studies.
I am surprised that there are not more entries here on the subject of Immunopower. That in itself concerns me.
My qualifications? I have been fighting cancer for 11 years now and have pretty much chased down all reasonable "cures" that have surfaced in those last years. Regretfully I have just learned that most modern laetrile products (Amygdalin) are not close to the potency of the original that Dr Krebs developed. This is disheartening since laetrile has strong studies showing that along with a healthy controlled diet it has a better "cure" rate than any chemo product. Read Dr Binzel's book "Alive and Well" for more info.
Hope this helps some.
