Nigella sativa (black caraway, also known as black cumin, nigella, kalonji, charnushka) is an annual flowering plant in the family Ranunculaceae, native to eastern Europe (Bulgaria and Romania) and western Asia (Cyprus, Turkey, Iran and Iraq), but naturalized over a much wider area, including parts of Europe, northern Africa and east to Myanmar. It is used as a spice in many cuisines. -- https://en.wikipedia.org/wiki/Nigella_sativa
