The use of Amygdalin (Laetrile/Vitamin B17) in the treatment of human cancer dates back at least to 1843, although the ancient Chinese are reported to have used bitter almonds containing significant quantities of it in the treatment of tumors some 3,000 years ago.

NATURAL SOURCE
Laetrile is not a miracle drug . It is simply a concentrated form of Nitriloside. Amygdalin (Laetrile/ Vitamin B17) is particularly prevalent in the seeds of those fruits in the Prunus Rosacea family (bitter almond, apricot, blackthorn, cherry, nectarine, peach and plum.) IT is found in natural foods which contain nitriloside and has been used and studied extensively for well over 100 years. It is also contained in grasses, maize, sorghum, millet, cassava, linseed, apple seeds, and many other foods that, generally, have been deleted from the menus of modern civilization. Fruit kernels or seeds generally have other nutrients as well, some protein, unsaturated fatty protein, unsaturated fatty acids, and various minerals. The most common source of B17 is the apricot kernel and is present in about a 2-3 percent levels of concentration within the seed kernel. 

So there is no confusion please note; there are 3 names which are interchangeable being Vitamin B17, Laetrile and Amygdalin. Vitamin B17 was the name given to the purified form of Amygdalin by a Bio Chemist named Ernst T Krebs in 1952. He also called it Laetrile which is simply short for Lavo-mandelonitrile and was awarded its vitamin status officially in 1952 after advice from Dr Dean Burke who was the co-founder of the National Cancer Institute. Amygdalin on the other hand is said to have been first discovered and used by a German chemist Leibig as far back as 1830. So, laetrile/Vitamin B17 on the other hand is simply a more soluable and concentrated form of amygdalin which allows it to be administered in a much greater concentration. Either way all 3 are essentially the same thing.

Vitamin B17 / Laetrile is probably one of the most controversial medical topics in the last 30 years. You may remember back in the 50's - mid 70's there was a lot hype in the medical world regarding a new natural cancer treatment that was discovered that killed cancer cells. This was the result of Dr Ernst Krebs findings and his research in a book called World Without Cancer. Well after several years of court cases and controversy regarding Laetrile it was finally stamped out by the FDA and reported to the mass media in the US as a fraud and failure. They called it Quackery in those days.

TODAY the hype has and is starting again as a result of THE INTERNET. The internet has allowed us to gain information from all over the world on what perhaps really happened and what is possibly one of the biggest cover-ups known to modern man regarding the treatment of cancer. When you look at what really happened you find the truth about laetrile.

SO WHAT IS B17? 
It is a non-toxic natural product that specifically targets cancer cells for their destruction and which poses as a serious threat to conventional drugs and the profits that cancer drugs make. Cancer is BIG business! The Cancer Drug companies have made every effort and attempt to make it illegal & unavailable through their lobbying of the governments and through their financial influence on the large charitable cancer institutions. Its all about $$$$ in the Mutli BILLION DOLLAR CANCER INDUSTRY
