If you have arrived here after typing celon, cylon, cyan, crylon, celine, salem or salon cinnamon into a search box, you are looking for the same thing: Ceylon cinnamon. None of those spellings is a separate species, a grade, or a brand. They are all attempts at one word.
That is worth saying plainly, because the confusion is not harmless. The distinction that actually matters in cinnamon is not how you spell it — it is whether you are buying Cinnamomum verum or one of the cassia species sold under the same shelf label.
Ceylon cinnamon is one species with one correct name
Ceylon cinnamon is Cinnamomum verum, also written Cinnamomum zeylanicum in older references. The English name comes from Ceylon, the former name of Sri Lanka, where the tree has been cultivated for export for centuries. It is often called true cinnamon, and that phrase is doing real work rather than marketing.
Everything else sold as cinnamon belongs to a different set of species — collectively cassia:
- Cinnamomum cassia — Chinese cassia, the most common
- Cinnamomum burmannii — Indonesian or Korintje cassia, the bulk of supermarket cinnamon in the United States
- Cinnamomum loureiroi — Saigon or Vietnamese cassia, the strongest tasting
In most countries all of these may be labelled simply “cinnamon”. That is legal, and it is why the spelling of Ceylon matters far less than the botany behind it.
How to tell them apart in your hand
You do not need a laboratory. The two look and behave differently enough to separate by eye.
The quill
Ceylon rolls into a quill made of many thin, papery layers, rather like a cigar. It is tan to light brown, brittle, and crumbles easily between your fingers. You can usually snap it without effort.
Cassia forms a single thick layer that curls inward from both edges, producing a hard, hollow tube. It is darker — reddish to deep brown — and woody. Trying to crumble it by hand is a losing battle.
The smell and the taste
Ceylon is delicate, faintly citrusy, and sweet without heat. Cassia is louder: sharper, more pungent, with a hot finish. If a cinnamon dominates whatever you put it in, it is almost certainly cassia.
Ground cinnamon
Once ground, the visual test disappears. Colour is a weak signal and grind fineness tells you nothing. At that point you are relying on the label, which is exactly why buyers who care about the species buy quills rather than powder.
Coumarin: the reason the distinction matters
Cassia contains coumarin, a naturally occurring compound that is hepatotoxic in sufficient quantity. Ceylon cinnamon contains only trace amounts.
The European Food Safety Authority has set a tolerable daily intake for coumarin of 0.1 mg per kilogram of body weight. For an adult of average weight that is a modest figure, and heavy daily use of cassia — the kind some people adopt after reading about cinnamon and blood sugar — can approach or exceed it.
Two honest caveats. Coumarin content varies considerably between cassia species and between batches, so no single conversion figure is reliable. And occasional culinary use of cassia is not the concern; sustained daily supplementation is. If you are taking cinnamon in quantity rather than cooking with it, the species you are taking is a legitimate question for your doctor, not a detail.
Why the misspellings exist at all
“Ceylon” is a place name that most English speakers have never seen written down, attached to a country that changed its name to Sri Lanka in 1972. People hear it, approximate it, and search for what they heard. Hence celon, cylon, cyan, and the rest.
A few of these have an additional source of confusion:
- Cylon is a spelling most people meet through science fiction, which makes it a natural guess.
- Cyan is a real word — a colour — so autocorrect will happily produce it and leave it alone.
- Salem and salon come from mishearing the second syllable rather than the first.
- Celine is a common given name, so predictive text tends to win that argument.
None of them denotes a product. If a seller uses one of these spellings on a label rather than in a search ad, treat it as a sign they are reselling without much knowledge of what they are handling.
What to ask before you buy
Whether you are buying a jar or a sack, the same four questions separate a real supplier from a reseller:
- What is the botanical name? A supplier of genuine Ceylon cinnamon will answer Cinnamomum verum without hesitation. Vagueness here is the answer.
- Where was it grown? Sri Lanka is the traditional origin, but Cinnamomum verum is also grown in the Seychelles, Madagascar, southern India and parts of the Caribbean.
- Quills or ground? Quills let you verify the species yourself. Ground cinnamon asks you to trust the label.
- Is there a certificate of analysis? For any volume purchase, ask. A lot-matched COA is the only documentary evidence of what you are receiving.
Price is a weak signal on its own, but a persistent one: genuine Ceylon costs meaningfully more than cassia, because the tree is harvested and the quills rolled by hand. Cinnamon sold at cassia prices and labelled Ceylon deserves a question.
The short answer
There is no such thing as celon, cylon, cyan, crylon, celine, salem or salon cinnamon. There is Ceylon cinnamon — Cinnamomum verum — and there is cassia. Learn to tell the quills apart, ask for the botanical name in writing, and the spelling stops mattering entirely.
Frequently asked questions
Is celon cinnamon the same as Ceylon cinnamon?
Yes. “Celon” is a misspelling of Ceylon. There is no separate product, species or grade by that name — you are looking for Cinnamomum verum.
What about cylon, cyan, crylon, celine, salem or salon cinnamon?
All the same word, misheard or mistyped. Ceylon is a place name — the former name of Sri Lanka — and it is unfamiliar enough in writing that people approximate it. None of these spellings denotes a distinct product.
How do I tell Ceylon cinnamon from cassia?
Look at the quill. Ceylon is made of many thin papery layers, is tan and brittle, and crumbles between your fingers. Cassia is a single thick layer curled into a hard, dark, hollow tube that resists breaking. Once ground, the test is no longer possible.
Why does the difference matter?
Cassia contains coumarin, which is hepatotoxic in sufficient quantity; Ceylon contains only traces. EFSA sets a tolerable daily intake of 0.1 mg per kilogram of body weight. Content varies between batches, so no single conversion figure is reliable. Occasional cooking is not the concern — sustained daily supplementation is, and that is worth raising with a doctor.
Is “true cinnamon” a marketing term?
No. It is the common English name for Cinnamomum verum — verum means “true” in Latin. It distinguishes the species from cassia rather than making a quality claim.
What should I ask a supplier?
Ask for the botanical name in writing, the country of origin, whether it is sold as quills or ground, and — for any volume purchase — a lot-matched certificate of analysis. A supplier who cannot name the species is reselling.
