Laetrile is the common name for a modified form of Amygdalin or B17, which is a common nitriloside found in many fruit seeds such as apricots, cherries, peaches, nectarines and apples.  It is also found in mung beans, chickpeas, bean sprouts, nuts, raspberries and blackberries.  All fruit seeds have a healthy form of cyanide that is contained in the nitriloside molecule.

The use of nitriloside, as an anti-cancer treatment, was pioneered by Dr. Earnest Krebs and he coined the name, "LAETRILE" in 1952

Medicinal Laetrile is extracted from apricot pits. Other names for this substance are B-17 or Amygdalin.


Laetrile as a Cancer Therapy

Amygdalin, or Laetrile, is lethal to cancer cells.  This is because cancer cells secrete the enzyme beta-glucosidase which releases the poisonous cyanide otherwise locked in laetrile, into the inside of the cell.

In the absence of cancer cells the toxic cyanide is not released.

Normal cells have an enzyme called rhodanase which effectively renders the cyanide molecule  inactive.

At Reno Integrative Medical Center, we administer B-17, Laetrile, in the context of a full-protocol and rarely use it alone. A truly effective alternative cancer treatment consists of using synergistic compounds together in a way that makes them far more powerful than if used as individual agents.

Laetrile as a cancer therapy was met by intense opposition by the Medical Establishment in the past.  Many physicians, who tried it in their protocols, had their licenses taken away by the "Powers that Be."

Eventually the political pressure became so great that Sloan-Kettering Hospital, (the first "Cancer Center" in the US), agreed to do research with it, ostensibly to see if it showed any benefit in the treatment of Cancer. They assigned one of their most respected, experienced researchers to do the work. When his studies started to show positive benefit, he was called on the carpet. He was told that in no way could he ever show any positive benefit from the use of this natural substance. He resigned instead of compromising his integrity.

There are a number of books about its' uses that can be purchased that describe how some open minded physicians, (including Dr. Brodie), applied it successfully in treating Cancer.

You can read about this in publications by Ralph Moss, PH.D., who worked at Sloan Kettering at the time this took place.

Through all the controversy it has managed to still be available and in use today. We offer it as a therapy here at Reno Integrative.
