VITAMIN B17 (Nitriloside, amygdaline)



Vitamin B17 is a large group of water-soluble, essentially non-toxic, sugary, compounds found in over 800 plants, many of which are edible. These factors are collectively known as beta-cyanophoric glycosides. They comprise molecules made of sugar, hydrogen cyanide, a benzene ring or an acetone.

Vitamin B17 is responsible for the thiocyanates in the body fluids (blood, urine, saliva, sweat and tears). It is part of the benzoic acid, hippuric acid, salicylic acid isomers and the hydrogen cyanide that is involved with the production of vitamin B12 (cyanocobalamin) from (pro-vitamin B12) hydrocobalamin.

Vitamin B17 is known to help combat liver disorders as well as support the liver’s ability to process and eliminate poisons in the body.

Vitamin B17 is a natural cyanide-containing compound that gives up its cyanide content only in the presence of a particular enzyme group called beta glucosidase. This enzyme group is found almost exclusively in cancer tissue, which results in the cancer's failure to survive the cyanide. There are no known harmful side effects of B17 and the cyanide in B17 does not affect non-cancerous cells and studies have proven this.

The seeds and stones of fruits such as apricots and peaches and some nuts contain high amounts of vitamin B17 and are one of the main courses of food in cultures such as Navajo Indians, Hunzas, Abkhasians and many more. Within these tribes there has never been a reported case of cancer. Some people with cancer have stayed with some of these tribes and their cancer has disappeared after just a few months of eating the same diet as them.

Seven apricots stones or three apples, including the seeds, contains about 100 mg of vitamin B17 and may be consumed daily to protect against and eliminate cancer. High concentrations of B17 are obtained by eating the natural foods in their raw or sprouting stage. This does not mean that moderate cooking will destroy the B17 content.

NOTE: Over consumption of some fruit seeds and stones can result in very unpleasant side effects caused by a natural toxin produced from them. It is therefore unadvisable to consume more than 100 grams in one day.

Apple, apricot, cherry and peach pips, seeds and stones and raw cassava (tapioca) contain cyanogenic glycosides causing cyanide poisoning. Seeds from one apple are unlikely to cause any ill effect but people have eaten enough to die from it. Cyanide is lethal because it impedes blood from carrying oxygen, which is of course a critical function of blood and is possibly why it can stop cancer cells developing as they require oxygen to multiply.

A fatal dose of cyanide can be as little as 1.5 mg/kg of body weight. Since an apricot kernel contains approximately 0.5 mg of cyanide, consuming 150 stones in a short period of time could be lethal to a 50 kg (110 lb) person.
