Nisam planirao da ulazim u novu diskusiju, ali previše mi je fascinantno kako si isekao citate iz sopstvenog izvora tako da potpuno izokreneš ono što su zapravo rekli."Laetrile is structurally different from its mother compound, amygdalin, and is an acronym (LAEvo-rotatory mandeloniTRILE beta-diglucoside) for a purified, semi-synthetic form of amygdalin. The "LAEvo" part references a purified form of amygdalin that turns polarized light in a left-turning direction."

"Dr. Krebs Jr. strongly argued against this artificial form and maintained that this mixture is less than 50% as effective as the pure form. Krebs writes that the RS epimer racemic mixture “caused unpredictable, often severe, reactions in our patients” and that “all of our successful therapeutic studies were conducted using only pure natural amygdalin.15 It is important to be aware that the amygdalin molecule which naturally occurs in hundreds of edible seeds and plants, is considerably unstable during and after extraction from its natural source. Slight variations in the extracting procedure can cause the amygdalin molecules to change to a form unknown to nature. These are known as isomers. Such a conformation is called neo-amygdalin. A mixture of natural amygdalin molecules and neo-amygdalin molecules is called “iso-amygdalin.”
"Amygdalin was later "rediscovered" in 1920 by California physician Dr. Ernst Theodore Krebs, Sr. His son, Dr. Ernst Krebs, Jr. through further research, developed the compound into the injectable chemical known as “Laetrile or B17.” Both amygdalin, and its patented form Laetrile, have been promoted and sold as "vitamin B-17", although neither compound is technically considered a “vitamin.” Laetrile is structurally different from its mother compound, amygdalin, and is an acronym (LAEvo-rotatory mandeloniTRILE beta-diglucoside) for a purified, semi-synthetic form of amygdalin. The "LAEvo" part references a purified form of amygdalin that turns polarized light in a left-turning direction. Dr. Krebs Jr. discovered that only this left-turning form of Laetrile was effective against cancer.1 "Laetrile" (with a capital "L") usually refers to the Krebses' original product, whose purification process was patented by them; "laetrile" (with a lower case "l") refers to the commercial form of amygdalin which is most likely a mixture of the left and right-turning forms, which the Krebses believed to be much less effective as a therapy for cancer. Natural amygdalin with the right turning configuration can be racemized to the unnatural form, neoamygdaline, during inexperienced extraction, bad packing or storage."
Znači dr. Krebs je taj koji je razvio, patentirao i promovisao Laetril kao lek za kancer.
"This NCI trial and its conclusion was widely publicized and considered to be definitive and the final word about Laetrile. Over the next few years, several doctors and scientists challenged the validity of this trial. In a letter to the editor of the New England Journal of Medicine, journalist Michael L. Culbert, D.Sc., founding member of the Laetrile Advocacy Group Committee for Freedom of Choice in Cancer Therapy, Inc., asserted that the trial did not use pure amygdalin.13 He revealed that the “laetrile” used in the clinical trial was a degraded or decomposed form or a “RS-epimer racemic mixture.” The RS epimer racemic mixture is a mixture of natural amygdalin (R-amygdalin) and an isomer,14 an artificial form of amygdalin (referred to as the S-isomer, or isoamygdalin). Dr. Krebs Jr. strongly argued against this artificial form and maintained that this mixture is less than 50% as effective as the pure form."
Znači dr. Krebs je smatrao da je lek koji je korišćen u studijama lošiji od leka koji je on patentirao i promovisao. Dr. Krebs nije imao ništa protiv prečišćenog, polusintetičkog amigdalina dok god bi pratio njegovu patentiranu recepturu.
