Laetrile is a partly man-made (synthetic) form of the natural substance amygdalin. Amygdalin is a plant substance found in raw nuts, bitter almonds, as well as apricot and cherry seeds. Plants like lima beans, clover and sorghum also contain amygdalin. Some people call laetrile vitamin B17, although it isn’t a vitamin.
How much amygdalin is in an apricot seed?
Apricot seeds have higher amygdalin content and comparatively easy deliver hydrogen cyanide than apple and peach. Amygdalin concentration of apricot varies between 0.1 and 4.1 mg/g as well as on the growing area and bitterness of seeds.
Is laetrile still being used?
The lack of laetrile’s effectiveness and the risk of side effects from cyanide poisoning led the Food and Drugs Agency (FDA) in the US and the European Commission to ban its use. However, it is possible to buy laetrile or amygdalin via the Internet.
Does heat destroy amygdalin?
The enzymes usually act at temperature of about 20-40oC and can be destroyed at higher temperature. Enzymatic hydrolysis of amygdalin in plant foods takes place within 30 min to 6 hr depending on the degree of maceration of the food sample (Tunçel, Nout & Brimer, 1995).
Which seeds have the most amygdalin?

Can laetrile cause cyanide poisoning?
Although supporters of laetrile as a cancer remedy maintain it has no toxicity, several reports document its toxic effects (238:482, 1977; 238:1361, 1977; 239:1532,1978). We report yet another case of cyanide poisoning from the ingestion of apricot seeds. Report of a Case.—
Why are apricot kernels poisonous to humans?
The kernels are believed to treat cancer, but they’re actually poisonous. Apricot kernels contain amygdalin, a compound also called laetrile, that is converted into cyanide in the body. Cyanide is toxic to cells because it interferes with their oxygen supply; it is particularly bad for the brain and heart, which require constant oxygen to function.
