A clinical trial of Laetrile (amygdalin) carried out in 1982 by the Mayo Clinic and three other U.S. cancer centers under National Cancer Institute sponsorship, found among other things that several patients suffered from cyanide poisoning.[3]>In 1993, The State Department of Agriculture and Markets of New York tested the cyanide content of two 8oz. packages of the bitter kernel which were being sold in health food stores as a health snack. The results returned showed that each package, if consumed entirely, contained at least double the lethal dosage of cyanide needed to kill a human being.They also seem to be at least fairly nutritious, besides killing you if you eat too much (probably a lot of stuff we eat is slightly toxic or more).Moral: Do some a little research before eating anything too different. Also: Everything in moderation, because neither science nor anybody else knows everything.
