Also known as kalonji or black seed, Nigella sativa is a small, angular, matte-black seed with a pungent, slightly bitter, onion-pepper aroma used as a spice and traditional medicine across the Middle East, South Asia, and North Africa.
History & Origins
Nigella sativa seeds have been found in archaeobotanical deposits from Egypt's New Kingdom and were discovered in Tutankhamun's tomb (~1323 BCE). The seeds are mentioned in the Hebrew Bible (Isaiah 28:25, 27) and in classical Greek medical texts by Dioscorides and Galen. They became a staple of Islamic prophetic medicine under the name 'habbat al-barakah' (the blessed seed), and were traded along spice routes into medieval Europe where they were known as 'Roman coriander.'
