prunus dulcis amara
Definition
Noun: * Almond tree with bitter nuts: A specific type of almond tree (Prunus dulcis var. amara) characterized by white blossoms. Its nuts are poisonous when raw due to the presence of amygdalin, a compound that can release cyanide. The oil extracted from these bitter almonds is used in small, controlled quantities for flavoring foods and in some medicinal applications.
Usage Notes
