Cherries and apples have seeds with traces of a cyanide derivative that can be converted in the stomach. > Cherries have a small, hardened pit that surrounds their seed, also called a kernel. The kernels of cherry pits and other stone fruits contain the chemical amygdalin. Amygdalin is a cyanogenic glycoside — a chemical that your body converts into the toxic compound hydrogen cyanide. In Ozark episode S2E19, Darlene poisons her husband Jacob's coffee with ground cherry pits, for a current cultural reference.
