Our experts from ‘The Keys To Cancer’ explains about the B17’s working principles. The method involves revolving around the cancer cells. Amygdalin consists of substances like benzaldehyde and hydrogen cyanide that are toxic in nature. Normal cells contain Rhodanese which are enzymes that helps to convert benzaldehyde and HCN into useful proteins and Vit. B-12 whereas cancer cells contain beta-glucosidase instead of Rhodanese and hence unable to convert the toxic substances into poison and thereby gets destroyed.
