WEB: Dr. Dean Burk (March 21, 1904 – October 6, 1988), head of the Cytochemistry section of the National Cancer Institute has reported that in a series of tests on animal tissue, the B-17 had no effect, but released so much cyanide and Benzaldehyde when it came in contact with cancer cells that not one of them could survive. He said, ”When we add Laetrile to a cancer culture under the microscope, we see the cancer cells dying off like flies.”
