European naturopathic practitioner Rudolph Breuss developed a forty-two day juice fasting program to nourish the body but starve cancer cells. There are variations for different kinds of cancer. Presented here are guidelines on how to implement these fasts. Following his instructions exactly is crucial to success. Although fasting seems irrational when the body is already wasting away, Breuss' patients felt more alert and energetic as soon as they began the treatment. Included are many grateful letters testifying to complete recoveries. Breuss also provides naturopathic and sometimes unusual treatment suggestions for a wide range of conditions from leukemia to rheumatism, infertility to cramps.
