Nigella seeds, sometimes called black cumin or kalonji, are the small, angular, jet-black seeds of a Ranunculaceae annual, prized for their smoky, onion-pepper aroma. They function as both a flavoring spice and a traditional remedy across South Asian and Middle Eastern cuisines.
History & Origins
Nigella sativa has been used medicinally and culinarily for more than three millennia; archaeologists found seeds in Tutankhamun's tomb (c. 1323 BCE), and they are described in the Ebers Papyrus and the Bible. Avicenna's Canon of Medicine praised the seeds for stimulating metabolism and easing breathing, while in Ayurveda they were classified as a pungent digestive tonic long before reaching European spice cabinets via Ottoman and Arab trade.
