Vitamin B17, which is the amygdalin compound, is a naturally occurring compound found in many plant based foods people consume.
Amygdalin is not actually a vitamin, but is called vitamin B17 because of its cancer fighting role in the body.

Laetrile Cancer Vaccine FAQs

Q : If amygdalin can be so helpful, why aren’t more cancer treatment centers using it?
A : The first argument is that it can be toxic because it contains cyanide. The second argument is that it doesn’t work.

Q : What about the argument that laetrile is not effective?
A : The only study ever published on the use of laetrile in cancer patients was sponsored by the National Cancer Institute and conducted at the Mayo Clinic and three other prominent oncological centers in the USA. The results were published in The New England Journal of Medicine (NEJM) in 1982.

In this article “A clinical trial of amygdalin (laetrile) in the treatment of human cancer,” Dr. Moertel, the head researcher, reported that of the 178 patients that were accepted in the study “not one patient was cured or even stabilized” by laetrile. Furthermore he said that “several patients experienced symptoms of cyanide toxicity” and that “blood levels of cyanide approaching the lethal range” were reported. “Laetrile has had its day in court…” says Moertel and ends authoritatively, “The evidence, beyond reasonable doubt, is that it [laetrile] doesn’t benefit patients with advanced cancer, and there is no reason to believe that it would be any more effective in the earlier stages of the disease.”

What’s disappointing about the article is the editorial bias of the NEJM. Why did the NCI and the Mayo Clinic bypass all scientific protocol? This study had no control group. It was not designed properly and not one of the researchers had any experience with laetrile. The NEJM, in normal conditions, will not publish studies that are not peer reviewed by experts on the subject. There are very few laetrile experts and all have worked with Dr. Francisco Contreras.

Q : How does Laetrile Kill Cancer Cells?
A : Tumors can become resistant to chemotherapy, radiation or whatever else you throw at it. It would make sense that if you could dismantle cancer’s defenses, you could then take it out, right? What are the ways that cancer defends itself?

One way is that tumors encapsulate themselves with blood vessels that are so restricted that antitumor agents can’t get through. Another way is that tumors amass high concentrations of a substance called glutathione.

Glutathione is the element that makes tumors resistant to treatment. Is there a way to lower the levels of glutathione in tumors so that they would become sensitized to anticancer treatments? The answer is yes. For glutathione to be produced in the cells, it needs another substance called cysteine.

Q : Is there a way to lower the level of Cysteine?
A : Yes. Cyanide depletes the supply of cysteine.

Q : Isn’t cyanide a poison?
A : Cyanide is toxic to our body but it will not make us sick in very low doses derived from a whole food source. You eat cyanide-rich food everyday if you eat apricots, pineapples, apples, or any of the other thousand cyanide-toting foods found in nature. The cyanide in these foods is present in a nutrient called amygdalin. Amygdalin can release cyanide within malignant cells, depleting the supply of cysteine. As a result, the intracellular concentration of glutathione is diminished. This will sensitize the tumors to antitumor treatments including Ozone therapy, Lymphocyte treatments, and high dose vitamin-C.
