Nigella sativa

Nigella sativa (Urdu: کلونجی‎) is an annual flowering plant in the family Ranunculaceae, native to south and southwest Asia. It 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. The seed is used as a spice, sometimes as a replacement for original black cumin (Bunium bulbocastanum).


The scientific name is a derivative of Latin niger (black).[2]

Common names[edit]

In English, Nigella sativa seed is variously called fennel flower,[3] nutmeg flower,[3] black caraway,[3] and Roman coriander.[3] Other names used, sometimes misleadingly, are black cumin,[3] onion seed and black sesame. Blackseed and black caraway may also refer to Bunium persicum.[4]

The seeds are frequently referred to as black cumin (as in Assamese: kaljeera or kolajeera or Bengali kalo jeera), but black cumin /kala jeera is different from Nigella sativa (kali jeeri). Original black cumin is Carum Bulbocastanum. In Kannada it is called [ಕೃಷ್ಣ ಜೀರಿಗೆ] Krishna jeerige, but this is also used for a different spice, Bunium persicum.

In English-speaking countries with large immigrant populations, it is also variously known as الحبّة السوداء al-ḥabbah al-sawdāʼ 'the black seed' or حبّة البركة ḥabbat al-barakah 'the seed of blessing' (Arabic), kaljeera (Assamese কালজীৰা kalzira or ক’লাজীৰা kolazira), kalo jira (Bengali: কালোজিরা kalojira, black cumin), μαυρόκοκκος mavrokokkos 'black seed' (Cypriot Greek), garacocco (Cypriot Turkish), קצח qetsaḥ (Hebrew), kalonji (Hindi कलौंजी kalauṃjī or कलोंजी kaloṃjī, Urdu كلونجى kalonjī) or mangrail (Hindi मंगरैल maṃgarail), jintan hitam (Indonesian), reşke (Kurdish), काळा जिरा kāḷā jirā (Marathi), سیاه‌دانه siyāh dāne (Persian), чернушка chernushka or калинджи kalindzhi (Russian), கருஞ்சீரகம் karuñcīrakam (Tamil), çörek otu (Turkish), karim jeerakam (കരിംജീരകം) in Malayalam or කළු දුරු in Sinhala, karto jeera in Beary, ( စမုန်နက် , samoun ne' ) in Myanmar.

It is used as part of the spice mixture paanch phoran or panch phoron (meaning a mixture of five spices) and by itself in a great many recipes in Bengali cookery and most recognizably in naan bread.[5]

The Turkish name çörek otu literally means "bun's herb" from its use in flavouring the çörek buns. Such braided-dough buns are widespread in the cuisines of Turkey and its neighbours (see Tsoureki τσουρέκι). In Bosnian, the Turkish name for N. sativa is spelled as čurekot. The seed is used in Bosnia, and particularly its capital Sarajevo, to flavour pastries (Bosnian: somun) often baked on Muslim religious holidays.


Nigella sativa has a pungent bitter taste and smell.[clarification needed] It is used primarily in confectionery and liquors. Peshawari naan is, as a rule, topped with kalonji seeds. Nigella is also used in Armenian string cheese, a braided string cheese called majdouleh or majdouli in the Middle East.


According to Zohary and Hopf, archaeological evidence about the earliest cultivation of N. sativa "is still scanty", but they report supposed N. sativa seeds have been found in several sites from ancient Egypt, including Tutankhamun's tomb.[6] Although its exact role in Egyptian culture is unknown, it is known that items entombed with a pharaoh were carefully selected to assist him in the afterlife.

The earliest written reference to N. sativa is thought to be in the book of Isaiah in the Old Testament, where the reaping of nigella and wheat is contrasted (Isaiah 28: 25, 27). Easton's Bible dictionary states the Hebrew word ketsah refers to N. sativa without doubt (although not all translations are in agreement). According to Zohary and Hopf, N. sativa was another traditional condiment of the Old World during classical times; and its black seeds were extensively used to flavour food.[6]

Seeds were found in a Hittite flask in Turkey from second millennium BCE.[7]

Traditional medicine[edit]

In the Unani Tibb system of medicine, black cumin (Carum bulbocastanum) is regarded as a valuable remedy for a number of diseases.[8] In Islamic writing, a hadith narrated by Abu Hurairah says "I heard Allah's Apostle saying, 'There is healing in black seed (al-ḥabbah al-sawdāʼ) for all diseases except death.'"[9]

Nestlé has reportedly filed a patent application covering use of N. sativa as a food allergy treatment.[10] Yet the firm denies the claim of patenting the plant, stating that the patent would only cover "the specific way that thymoquinone - a compound that can be extracted from the seed of the fennel flower - interacts with opioid receptors in the body and helps to reduce allergic reactions to food".[11]


Nigella sativa oil contains an abundance of conjugated linoleic (18:2) acid, thymoquinone, nigellone (dithymoquinone),[12] melanthin, nigilline, damascenine, and tannins. Melanthin is toxic in large doses and nigelline is paralytic, so this spice must be used in moderation.[citation needed]


Black seed oil has been claimed to treat a wide range of ailments [13] but evidence is currently limited to in vitro and animal stidies[14]
