Come on, don't spread lies and bullshit. People might fall for it. Where to start...
First, there has already been clinical trials of amygdalin (Laetrile) since the 80s and found that indeed there was no benefit observed. Here is the link to the trial in a peer reviewed journal https://www.ncbi.nlm.nih.gov/pubmed/7033783
Also, here is a review study where comparing different studies in literature review concluded that there is no convincing evidence that amygdalin pas positive effects on cancer patientes.

You listed the book Naturally Occurring Glycosides and copy pasted the resume content from the Wiley website (by the way the link is wrong here it is the correct one)
https://www.wiley.com/en-nl/Naturally+Occurring+Glycosides-p-9780471986027
I don't know if the information is correct as I do not own the book but here is a multiple articles review on Cyanogenic glycosides in ScienceDirect stating the toxicity and no effect on cancer treatment

Edward Griffin was a writer not a doctor, or scientist, or researcher.
Did not cared to look further than that here is his wikipedia
https://en.wikipedia.org/wiki/G._Edward_Griffin
You make the statement "Laetrile has a specific cancer preventive and controlling effect"
where is your proof backing it up. I tried to look for a publication by Dean Burk related to his study but I could not find one (please if you have it I would like to read it).
Phillip Day also is not educated in medicine or science, he is a sales and marketing guy. He also has not published in a peer reviewed journal about his findings.
Please don't spread false information that can harm someone.
