Mustard seeds come primarily from plants of the Brassica genus, including white mustard (Brassica alba), yellow mustard (Brassica nigra), and black mustard (Brassica juncea). Native to regions of the Mediterranean, Asia, and Europe, these seeds have been cultivated and used in gastronomy and traditional medicine since ancient times.
