  • However, amygdalin preparations contaminated with beta-glucosidases, seen particularly when the product is made from apricot seeds, may enhance the hydrolysis of amygdalin and thus considerably increase its toxicity. (cam-cancer.org)
  • Amygdalin is the natural, raw substance that comes from the seeds or kernels of many fruits including apricots, but it is also present in lima beans, clover, and sorghum. (alivenhealthy.com)
  • In treating one of my patients for a rare form of blood vessel cancer (by the way, he seems to be doing very well so far), a Japanese neighbor of his recommended that he drink loquat leaf tea (just as herbalists on Cyprus were recommending) and that he eat 2 loquat seeds daily because these are some 1300 times higher in amygdalin than the leaves.

  • However, the quality of this study is questionable since a heterogeneous patient cohort was used, no control groups were included, and a racemate instead of pure amygdalin was used for the i.v. therapy. (spandidos-publications.com)
  • As opposed to oral administration, there is no proof for toxicities associated with parenterally administered pure amygdalin. (cam-cancer.org)

  • By the 1920s amygdalin had reached the US, but the early pill form was considered to be too toxic and its use was discontinued. (cam-cancer.org)
  • Amygdalin is toxic in high amounts. (health-matrix.net)
  • Vitamin B17 is a name that was coined by Dr. Eugene Krebs, Jr. He was the one who first discovered amygdalin and since this substance is naturally-occurring, non-toxic, water-soluble, and able to be metabolized by humans, he referred to it as a vitamin. (alivenhealthy.com)

  • For the most part, it has been found that amygdalin is devoid of any significant activity against tumor cells and can be lethal if ingested in excessive amounts. (fsu.edu)
  • Furthermore, amygdalin induced a marked decrease in cell cycle activating proteins, in particular cdk1 and cyclin B. Functional blocking of cdk1 and cyclin B resulted in significantly diminished tumor cell growth in all three RCC cell lines. (spandidos-publications.com)
