Enzyme therapy is generally broken down into two types: food enzymes and Proteolitic enzymes. Several researchers including Dr. John Beard, Dr. Ernst Krebs, Jr., and Dr. Dean Burk found that the cancer cell is coated with a protein lining and that it is this protein lining (or covering) that prevents the body’s normal defenses from getting to the cancer cell. They found that, if you can dissolve the protein lining from around the cancer cell, the body’s normal defenses, the leukocytes (white blood cells), will destroy the cancer cell. Woebenzyme is a product from Germany that appears to do just that. Chapters five and six of the book World Without Cancer describe this process in more detail.
