Karunjeeragam in English: What the Tamil Name Actually Means
If you have searched for karunjeeragam in English, you have probably already been given two different answers and no way to choose between them. One says black cumin. One says nigella, or black seed, or kalonji. Both appear on packets in the same shop, sometimes on the same packet. The honest answer has two halves, and almost everyone gives only the first. Karunjeeragam (கருஞ்சீரகம்) is Nigella sativa — the seed known in English as black seed or nigella seed, and in Hindi and Urdu as kalonji. But the literal translation, “black cumin”, is the single worst English phrase to shop with, because English uses it for at least two other plants that are not karunjeeragam at all.
For our own oil pressed from that seed, see our cold-pressed Ethiopian black seed oil — Nigella sativa, independently verified at 2.67% thymoquinone per batch by Analytice, an ISO-accredited French laboratory.
The Short Answer
- Karunjeeragam is Nigella sativa. In English the safest names are black seed or nigella seed. It is the same seed as kalonji.
- The word breaks down as “black cumin” — karu (black) plus seeragam / jeeragam (cumin) — which is a fair translation and an unreliable shopping term.
- Nigella sativa is not a cumin. It belongs to Ranunculaceae, the buttercup family. True cumin is Cuminum cyminum, in the carrot family. They are not related.
- English “black cumin” is also used for Bunium persicum — kala jeera or shahi jeera — and occasionally for Centratherum anthelminticum, sold as kali jiri. Neither is karunjeeragam.
- You can tell them apart by eye. Karunjeeragam seeds are matte black, angular and wedge-shaped — about 2–3.5 mm long and 1–2 mm wide, so roughly twice as long as they are broad, with flat facets and no ridges. Kala jeera is dark brown, longer, slender, curved and ridged.
- For cooking, the name rarely matters much. For anything where you want thymoquinone, it decides everything — because only Nigella sativa produces it in meaningful quantity.
Karunjeeragam in English: The Direct Answer
Karunjeeragam in English is black seed, also called nigella seed, from the plant Nigella sativa. It is the same seed sold as kalonji in Hindi and Urdu and as habbat al-sawda in Arabic. “Black cumin” is the common literal translation, but in English that phrase also names two unrelated plants, so it is not a safe shopping term.
That is the whole answer, and if you only came for a word, you can stop reading. What follows is why the confusion exists and how to make sure the packet in your hand is the right plant — which is a different question from what the word means.
Tamil is not the source of the muddle. Within Tamil, karunjeeragam consistently denotes Nigella sativa; you will also see it written கருப்பு சீரகம் (karuppu seeragam), meaning the same thing. The muddle is introduced at the point of translation into English, and then amplified by international retail.
Why “Black Cumin” Is the Wrong English Word to Shop With
English has been careless with this plant for centuries. It has also been called black caraway, roman coriander, fennel flower and onion seed, none of which describe anything botanically true. “Black cumin” is the one that has stuck, and it is the one that does real damage, because two other seeds are traded under exactly that label.
| Sold in English as | Botanical name | Plant family | What the seed looks like | Is it karunjeeragam? |
|---|---|---|---|---|
| Black seed, nigella, kalonji, black cumin | Nigella sativa | Ranunculaceae (buttercup) | Matte black, angular, wedge-shaped — 2–3.5 mm long by 1–2 mm wide, about twice as long as broad | Yes |
| Black cumin, kala jeera, shahi jeera | Bunium persicum (syn. Elwendia persica) | Apiaceae (carrot) | Dark brown, slender, curved, ridged, tapering at both ends | No |
| Black cumin, kali jiri, kalijiri | Centratherum anthelminticum | Asteraceae (daisy) | Small, dark, faintly hairy, intensely bitter | No |
| Cumin, jeera, seeragam | Cuminum cyminum | Apiaceae (carrot) | Larger, yellow-brown, boat-shaped, ridged | No |
Only the first row produces thymoquinone in any meaningful amount. That is why the distinction is not pedantry: if you are buying because of what you have read about black seed, the other three rows will not give you it, however good they are in a biryani.
One observation from putting this article together. When we searched “karunjeeragam in english” in August 2026, the highest-ranking marketplace listing carried “Karunjeeragam”, “Kala Jeera” and “Kalonji” in a single product title — two different plants presented as synonyms, at the top of the page a beginner would land on. We are not naming the seller, because this is not one seller's failing; it is what the category looks like. We have written about the wider tangle in our guide to whether black cumin oil is the same as black seed oil.
The Tamil Seeds That Trip People Up
Tamil attaches the -jeeragam ending to several seeds that have nothing to do with each other botanically. It is a description of role in the kitchen — small aromatic seed — rather than a claim about ancestry, and English readers who assume otherwise get lost quickly.
| Tamil | Transliteration | Usual English | Botanical name | Family |
|---|---|---|---|---|
| சீரகம் | seeragam / jeeragam | Cumin | Cuminum cyminum | Apiaceae |
| கருஞ்சீரகம் | karunjeeragam | Black seed / nigella | Nigella sativa | Ranunculaceae |
| கருப்பு சீரகம் | karuppu seeragam | Black seed / nigella (same seed) | Nigella sativa | Ranunculaceae |
| பெருஞ்சீரகம் / சோம்பு | perunjeeragam / sombu | Fennel | Foeniculum vulgare | Apiaceae |
A note on the fourth row, because it is genuinely unsettled: perunjeeragam is most often fennel and is interchangeable with sombu in everyday Tamil, but some sources use it for caraway. If you meet the word on a packet rather than in a recipe, it is worth checking the botanical name rather than assuming.
The practical upshot for karunjeeragam is simpler. Two Tamil forms, one plant, and neither of them is a cumin.
Karunjeeragam Across South Asia and the Arab World
The same seed carries a different name in almost every language that has cooked with it, which is a reasonable measure of how long and how widely it has been used. The names below all denote Nigella sativa.
| Language | Name | In script |
|---|---|---|
| Tamil | karunjeeragam | கருஞ்சீரகம் |
| Malayalam | karinjeerakam | കരിഞ്ചീരകം |
| Telugu | nalla jeelakarra | నల్ల జీలకర్ర |
| Kannada | kari jeerige | — |
| Hindi and Urdu | kalonji (kalaunji) | कलौंजी |
| Bengali | kalo jeera | — |
| Arabic | habbat al-sawda | الحبة السوداء |
| Sanskrit | upakunchika | — |
| English | black seed, nigella seed | — |
One Sanskrit name is worth keeping out of that list. Krishna jeeraka — literally “black cumin” again — belongs in Ayurvedic nomenclature to the carrot family, as the dark half of the jeeraka dwaya pair, and is applied to Carum carvi and to Bunium persicum. It is not Nigella sativa. The Sanskrit name that does belong to nigella is upakunchika.
The Arabic name is the one many readers will have met first. Habbat al-sawda — often written habbatus sauda — means simply “the black seed”, and it appears in the hadith literature, most familiarly in the narration recorded in Sahih al-Bukhari 5688, in which the Prophet Muhammad ﷺ describes the black seed as a healing. It is quoted here as a matter of naming and tradition, held in the respect it is due; it is not a claim about any product, and Sidr & Stone does not make one. We have written about that tradition properly in our guide to black seed oil in Islam.
How to Check the Packet in Front of You
Four checks, in the order they are worth doing.
- Look for the botanical name. Nigella sativa printed anywhere on the packet settles the question outright. Its absence settles nothing, but it is a fair signal about how carefully the seller works.
- Look at the seed. Karunjeeragam is matte rather than glossy, black rather than brown, and angular — a small three-sided wedge roughly 2–3.5 mm long and 1–2 mm wide, so about twice as long as it is broad, with flat facets and no ridges. Kala jeera is longer, obviously slender, curved, ridged and tapering at both ends. You do not need a lens, though one helps.
- Smell it. Karunjeeragam is peppery with a faint oregano or onion note. Cumin and kala jeera are warm, earthy and unmistakably cumin-like. They do not smell alike.
- Read the other names on the label. A packet that lists kalonji, nigella and black seed together is internally consistent. A packet that lists kalonji and kala jeera as if they were the same thing has told you the seller is working from a list rather than from the plant.
If the seed is going into food, that is enough. If it is going into anything where you care about composition, the checks go further — origin, pressing method, and an independently measured figure — and we set those out in our guide to high quality black seed oil. For background on the plant itself, see Nigella sativa: the plant behind black seed oil.
Three Fair Objections
“Every Tamil grocery site translates it as black cumin. Are they all wrong?” No. As a translation it is the standard gloss and it is defensible — the word does mean black cumin, morpheme for morpheme. Our point is narrower: it is a poor shopping term, because the English phrase has been claimed by other plants. Translation and purchasing are different jobs and the same word can be right for one and wrong for the other.
“It is a spice. Does the name really matter?” For cooking, mostly not. If you sprinkle the wrong black seed on naan you will get a different flavour and no harm done. It matters when the reason you are buying is something you read about Nigella sativa specifically — at that point the name is the only thing standing between you and a different plant.
“You sell black seed oil, so of course you say karunjeeragam is your product.” Fair, and worth saying plainly: we have a commercial interest here. The difference is that this one is checkable without us. The botanical families are a matter of public record, the seed shapes are visible on your kitchen table, and nothing in this article depends on taking our word for anything.
Why Sidr & Stone
An article about getting a name right ought to be held to the same standard about its own product. Ours is pressed from one plant, named on the label, and measured by someone other than us.
- Independently verified 2.67% thymoquinone, tested per batch
- Tested by Analytice, an ISO-accredited French laboratory
- Organically grown Ethiopian highland Nigella sativa — chosen after a 36-supplier evaluation
- Cold-pressed below 40°C to protect the heat-sensitive thymoquinone
- 100% pure — single ingredient, nothing added
- Unrefined — preserving the oil's natural integrity, so fine sediment is normal
- Bottled in matte black UV-protective glass
- Halal certified
- 10% of profits to charity
- Fulfilment in the UK, EU, and US
We will not tell you Sidr & Stone is the strongest or the best. What we will say is that our thymoquinone figure is 2.67%, independently verified per batch, and that the plant on the label is the plant in the bottle.
Frequently Asked Questions
What is karunjeeragam in English?
Karunjeeragam is black seed, also called nigella seed, from the plant Nigella sativa. It is often translated literally as “black cumin”, but that English phrase is also used for unrelated plants, so black seed or nigella seed is the safer term to use when buying.
Are karunjeeragam and kalonji the same?
Yes. Kalonji is the Hindi and Urdu name and karunjeeragam is the Tamil name for the same seed, Nigella sativa. Any difference between two packets is a difference of origin, freshness or grade — not of plant.
Is karunjeeragam the same as kala jeera?
No, and this is the confusion worth avoiding. Kala jeera or shahi jeera is Bunium persicum, a carrot-family plant used mainly in Kashmiri, Punjabi, Afghan and Iranian cooking. Its seeds are dark brown, slender, curved and ridged. Karunjeeragam seeds are matte black, angular and wedge-shaped, with flat facets rather than ridges.
How do I tell karunjeeragam from ordinary seeragam?
Colour and shape. Seeragam — cumin — is yellow-brown, elongated and ridged, and smells warm and earthy. Karunjeeragam is matte black, faceted and wedge-shaped — about 2–3.5 mm long by 1–2 mm wide, so roughly twice as long as it is broad, with flat sides rather than ridges — and smells peppery with a faint oregano note.
Can karunjeeragam be eaten every day?
It is an ordinary culinary spice across South Asia and the Middle East and is eaten routinely in food in small amounts. Supplemental quantities are a different question, and anyone who is pregnant, breastfeeding, or taking prescribed medication should speak to a qualified medical professional before adding a concentrated supplement to their routine.
What is karunjeeragam called in Malayalam, Telugu and Hindi?
Karinjeerakam (കരിഞ്ചീരകം) in Malayalam, nalla jeelakarra (నల్ల జీలకర్ర) in Telugu, kari jeerige in Kannada, and kalonji (कलौंजी) in Hindi and Urdu. All refer to Nigella sativa.
Where can I buy oil made from real karunjeeragam?
From a producer who names Nigella sativa on the label and publishes an independent certificate of analysis you can read. Sidr & Stone's oil is cold-pressed from organically grown Ethiopian highland Nigella sativa and verified at 2.67% thymoquinone per batch, with fulfilment in the UK, EU, and US. If you are comparing sellers, our guide to buying black cumin seed oil covers what to check.
Is black seed oil a medicine?
No. Black seed oil is a food supplement, not a medicine. It has a long traditional history and an interesting body of research around thymoquinone, and can be a worthwhile part of a healthy routine — but it does not cure diseases and is not a substitute for medical care. Be cautious of any black seed oil marketed with specific disease-cure claims.
Final Thoughts
Karunjeeragam in English is black seed. The literal translation is black cumin, and the reason we keep pulling those two apart is not fussiness — it is that English handed the phrase “black cumin” to three different plants and never took it back.
Tamil was never the problem. A language that has cooked with this seed for centuries knows exactly which seed it means. What travels badly is the translation, and what travels worst of all is a translated name printed on a label by someone who has never handled the plant.
So use the botanical name when it matters. Nigella sativa is unambiguous in every language and every market, and it is the one word on a packet that cannot be argued with.
Our cold-pressed Ethiopian black seed oil — pressed from Nigella sativa and independently verified at 2.67% thymoquinone — is available now, with fulfilment in the UK, EU, and US.
