Cochrane: Laetrile
is a word created from the first letters of laevorotatory and
mandelonitrile and describes a semi-synthetic form of amygdalin.
Amygdalin is a compound that can be isolated from the seeds of many
fruits such as peaches, bitter almonds and apricots. Both laetrile and
amygdalin have a common structural component, mandelonitrile, that
contains cyanide.
