Nigella sativa (black caraway, also known as black cumin, nigella, kalojeera, kalonji or kalanji) is an annual flowering plant in the family Ranunculaceae, native to eastern Europe (Bulgaria, Cyprus and Romania) and western Asia (Turkey, Iran and Iraq), but naturalized over a much wider area, including parts of Europe, northern Africa and east to Myanmar.
N. sativa grows to 20–30 cm (7.9–11.8 in) tall, with finely divided, linear (but not thread-like) leaves. The flowers are delicate, and usually coloured pale blue and white, with five to ten petals. The fruit is a large and inflated capsule composed of three to seven united follicles, each containing numerous seeds which are used as spice, sometimes as a replacement for black cumin (Bunium bulbocastanum).

In the United States, the Food and Drug Administration classifies Nigella sativa L. (black cumin, black caraway) as Generally Recognized as Safe (GRAS) for use as a spice, natural seasoning, or flavouring. The seeds of N. sativa are used as a spice in many cuisines. In Palestine, the seeds are ground to make bitter qizha paste.
The dry-roasted seeds flavour curries, vegetables, and pulses. They can be used as a seasoning in recipes with pod fruit, vegetables, salads, and poultry. In some cultures, the black seeds are used to flavour bread products, and are used as part of the spice mixture panch phoron (meaning a mixture of five spices) and alone in many recipes in Bengali cuisine and most recognizably in naan. Nigella is also used in tresse cheese, a braided string cheese called majdouleh or majdouli in the Middle East.
Archaeological evidence about the earliest cultivation of N. sativa dates back three millennia, with N. sativa seeds found in several sites from ancient Egypt, including Tutankhamun's tomb. Seeds were found in a Hittite flask in Turkey from the second millennium BC.
N. sativa may have been used as a condiment of the Old World to flavour food. The Persian physician Avicenna in his Canon of Medicine described N. sativa as a treatment for dyspnea. N. sativa was used in the Middle East as a traditional medicine.
Oils are 32% to 40% of the total composition of N. sativa seeds. N. sativa oil contains linoleic acid, oleic acid, palmitic acid, and trans-anethole, and other minor constituents, such as nigellicine, nigellidine, nigellimine, and nigellimine N-oxide. Aromatics include thymoquinone, dihydrothymoquinone, p-cymene, carvacrol, α-thujene, thymol, α-pinene, β-pinene and trans-anethole. Protein and various alkaloids are present in the seeds.
One meta-analysis of clinical trials found weak evidence that N. sativa has a short-term benefit on lowering systolic and diastolic blood pressure, with limited evidence that various extracts of black seed can reduce triglycerides and LDL and total cholesterol, while raising HDL cholesterol. Despite considerable use of N. sativa in traditional medicine practices in Africa and Asia, there is insufficient high-quality clinical evidence to indicate that consuming the seeds or oil provides any benefit to human health.
