Peach (fruit)
Phytochemicals
As with many other members of the rose family, peach seeds contain cyanogenic glycosides, including amygdalin (note the subgenus designation: Amygdalus). These substances are capable of decomposing into a sugar molecule and hydrogen cyanide gas. While peach seeds are not the most toxic within the rose family (see bitter almond), large consumption of these chemicals from any source is potentially hazardous to animal and human health.
