It is known for containing amygdalin, a poisonous compound that, together with the related synthetic compound laetrile, has been marketed as an alternative cancer treatment. However, studies have found the compounds to be ineffective in the treatment of cancer, as well as potentially toxic or lethal when taken by mouth, due to cyanide poisoning.
Taken in excess, they may produce symptoms of cyanide poisoning, including nausea, fever, rash, headaches, insomnia, increased thirst, weakness, lethargy, nervousness, various aches and pains in joints and muscles, and a drop in blood pressure.
In 1993, the New York State Department of Agriculture and Markets tested the cyanide content of two 220 gram (8 oz) packages of bitter apricot kernels imported from Pakistan that were being sold in health-food stores as a snack. The results showed that each package, if consumed entirely, contained at least double the minimum lethal dosage of cyanide for an adult human. The apricot pits were recalled and removed from stores. There was one reported case in the medical literature of cyanide toxicity from apricot kernels from 1979 to 1998 in the United States.
