I'm not questioning the toxicity of amygdalin. I'm questioning its medical efficacy. My problem with it is, that there is absolutely no credible evidence that laetrile, vitamin B17, or amygdalin does anything towards its defined goal of stopping cancer. All evidence that "supports" its claims is anecdotal.
I'm not exactly sure as to why you included anything at all about zinc's role in activating laetrile.
