Dalchini: Ceylon vs Cassia Cinnamon, and Which One You Actually Have
Most of what gets sold as cinnamon in South Asia, and in a good half of the world’s supermarkets, is not cinnamon in the strict sense. It’s cassia, its thicker, louder cousin, and knowing which one is in your hand changes how you cook with it and how much of it is sensible.
The short version
- Traditionally used for: warmth after a cold, easing a heavy stomach after rich food, sweetening the breath, and flavouring qahwa, garam masala and biryani.
- Typical amount: a 3 to 5 cm quill, or a quarter to half a teaspoon of ground, per pot of food or tea.
- Best form: whole quills, bought small and ground as needed. Ceylon if you drink cinnamon tea often.
- Go easy if: you’re pregnant, on diabetes medication or blood thinners, have a liver condition, or you’re reaching for cassia every single day.

Two different barks wearing the same name
Cinnamon is the inner bark of a tree, peeled and dried, curling in on itself as it loses water. That’s all a quill is. Several related trees give a bark that smells roughly like cinnamon, and only one is what traders call true cinnamon: Ceylon, from Sri Lanka. Cassia comes from China, Indonesia and Vietnam, and it’s what most of the world actually buys. In Urdu and Hindi both are dalchini, which is honest enough in the kitchen and unhelpful at the shop counter.
Telling them apart with your hands
You don’t need a label. Pick up the stick.
Cassia is thick, hard and heavy, a single layer of bark rolled into one tube, dark reddish brown, almost the colour of old brick. Try to snap it and it fights you. In a mortar it skitters and shatters rather than powdering. The smell is strong, hot, a little medicinal, the smell of cinnamon chewing gum.
Ceylon is thin, pale and fragile. Tan, the colour of a manila envelope, and instead of one thick tube it’s many thin layers packed inside one another like a cigar. Press it between finger and thumb and it crumbles. The smell is softer and sweeter, with something almost floral behind it.
Ground, you’re mostly guessing. Ceylon powder runs lighter and fawn, cassia darker and redder, but blends exist. That’s the honest argument for buying whole.
In Unani thinking dalchini sits firmly on the hot and dry side, which is why it belongs to winter and to the cup you make when someone has been sniffing all evening. Ayurvedic tradition treats it as warming too, usually described as kindling the digestive fire, often paired with dried ginger and fresh adrak. These are traditional descriptions of how the spice was understood, not statements of proven effect.
The coumarin question, said plainly
Here’s the part most cinnamon articles skip or bury. Cassia bark naturally contains a compound called coumarin, and a good deal more of it than Ceylon does. That’s a well established difference between the two barks, not a controversy, and it’s why food safety bodies in several countries treat large daily intakes of cassia as something to avoid, with the liver as the organ of concern.
What’s fair to say is this: used in the amounts a spice is normally used in, cassia is ordinary food people have cooked with for centuries. As a daily heaped spoonful stirred into a smoothie because someone online said to, it stops being a seasoning and becomes a habit nobody has good reason to recommend.
So the practical rule. Keep cassia to culinary amounts, the quill in the rice, the dusting on the porridge. If cinnamon tea is a daily thing in your house, buy Ceylon for it.
Buying, storing, and knowing when it’s dead
Buy whole quills wherever you can. Bark holds its oils inside itself; powder starts losing them the second the grinder stops. A jar of ground cinnamon opened weekly is tired in four to six months and pointless after a year. Whole quills, sealed and away from the cooker, hold up for two years or more.
The staleness test takes ten seconds. Snap a quill, or rub a pinch of powder hard between your palms to warm it, then smell. Fresh cinnamon hits you at once, sweet and hot together. Stale cinnamon smells of cardboard and dust, and you have to go looking for the cinnamon underneath.
Store it dark, dry and cool. Not on the shelf above the hob, where steam and heat cook it slowly all year. Not in the fridge either, since the jar sweats every time it comes out. A cupboard is fine, and 50 to 100 g at a time beats the economy bag.
Where it actually goes in the kitchen
In a South Asian kitchen the quill goes in early and whole. Hot oil or ghee, a stick of dalchini alongside cloves, a bay leaf and green cardamom, thirty seconds until the oil smells of all of it, then the onions. That’s the opening move of half the pulaos on the subcontinent. In garam masala it’s a backbone spice, ground with cloves, cumin, coriander and black pepper. In biryani it perfumes the rice water rather than the masala.
Arab and Levantine cooking uses it more openly. Cinnamon in the rice with the lamb, cinnamon in the coffee, cinnamon leaning into savoury food in a way that surprises people who only know it from apple cake. Gulf qahwa often carries cardamom, saffron and a little cinnamon together, and Kashmiri kahwa is as much ritual as recipe.
One practical note. Cassia holds up better in long braises because it’s blunt and durable. Ceylon is delicate and suits drinks and milk puddings, where its sweeter edge actually shows.
Cinnamon qahwa, measured properly
This makes two small cups, the size you’d actually serve after dinner. Ceylon is the better choice here.
- Put 350 ml of cold water in a small pan.
- Break one 5 cm Ceylon quill (roughly 1.5 g) into two or three pieces and drop it in. Breaking it matters, since the cut edges are where the flavour leaves.
- Lightly crush 3 green cardamom pods with the flat of a knife and add them.
- Bring to a bare simmer over medium heat, about 3 to 4 minutes. You want lazy bubbles at the edge, not a rolling boil, which turns cinnamon bitter.
- Turn the heat to low and hold it there for 8 minutes. The water will go the colour of weak tea.
- Take it off the heat. If you want it, stir in a quarter teaspoon of loose green tea and cover for 2 minutes, no longer.
- Strain into two cups. Add up to 1 teaspoon of honey per cup once it’s cool enough to drink comfortably, and a few slivered almonds if you’re being generous.
For a plainer everyday cup, one 3 to 5 cm quill in 250 ml water, simmered gently for 10 minutes, strained. That’s the version most households actually make.
How much, how often
Ordinary cooking amounts are the honest answer. One quill of 3 to 5 cm per pot of rice, curry or stew feeding four to six people. A quarter to half a teaspoon of ground cinnamon (roughly 0.5 to 1.5 g) in a cake batter, a bowl of porridge or a pot of tea. One cup of cinnamon tea a day, or one or two on a cold week, is the rhythm in most homes, and there’s no tradition anywhere of drinking it by the litre.
If you find yourself measuring cinnamon in tablespoons, stop and ask what you’re trying to achieve. A spice that tastes good in a pinch does not get better in a heap, and with cassia the coumarin point above is the reason to keep it seasoning rather than supplement.
You’re pregnant or breastfeeding: food amounts in cooking are normal, but daily concentrated cinnamon drinks or supplements aren’t something to start without asking your own doctor. You take diabetes medication: cinnamon is popularly linked with blood sugar, which is a reason to talk to your prescriber before making it a ritual, not to quietly add it. You take blood thinners, or have surgery or dental work coming up. You have any liver condition, where daily cassia in particular is worth raising with your doctor. Cinnamon oil is a different thing from the spice and can irritate or burn mouth, gums and skin, so never swallow it neat or dab it on a toothache. Children should have it as food in food, not as strong decoctions. And the so called cinnamon challenge, swallowing a spoonful of dry powder, is a genuine hazard rather than a prank: the powder can be inhaled into the lungs and has caused serious harm. Never do it, and tell the teenagers in your house why.
On the skin, and on the tongue
Cinnamon turns up in homemade scrubs and masks, usually a pinch stirred into honey. It’s also one of the more common contact irritants in the spice rack, so treat any leave on use with respect. Patch test first: mix what you plan to use, put a dab the size of a lentil on the inside of your forearm, leave it 24 hours, and wash it off at the first sign of stinging, redness or heat. If it reacts there, it will react worse on your face. Leave cinnamon essential oil alone unless someone qualified has told you otherwise. Chewing a small piece of bark for the breath is fine, and has nothing to do with putting drops of oil on the gums, which is not.
| Common belief | Closer to the truth |
|---|---|
| Cinnamon controls blood sugar. | A popular kitchen claim, and exactly the one to take to your doctor rather than the spice jar if you’re on medication. |
| All cinnamon is the same, the expensive one is a scam. | Different barks, different trees, different chemistry. Cassia for cooking, Ceylon for daily drinking. |
| Cinnamon tea burns fat. | No food does that. It does make a warm drink taste good without sugar, which is modest and real. |
| A spoonful a day is a healthy habit. | No tradition backs daily spoonfuls, and with cassia it’s a poor idea. Season your food and enjoy it. |
| Cinnamon oil is just concentrated cinnamon. | Far stronger and differently behaved. It irritates skin and mouth tissue and isn’t a kitchen ingredient. |
Worth trying once
Buy one small pack of Ceylon quills, even if you already have cinnamon. Put a piece of each on the counter, snap them both, smell them side by side. You’ll never confuse them again, and you’ll know which one your usual shop has been selling you. Then use the cassia in a slow lamb curry and the Ceylon in the qahwa above.
A last word on where this fits
Cinnamon carries the smell of a South Asian kitchen, along with green cardamom and cloves, and it belongs in food. Treat this as kitchen lore, not medical guidance. If you’re on medication, pregnant, managing a health condition, or thinking of making cinnamon a daily habit rather than an ingredient, ask your own doctor first.

Dalchini questions people actually ask
How can I tell Ceylon cinnamon from cassia?
Pick up the stick. Cassia is a thick, hard, single dark red-brown layer that fights you when you try to snap it. Ceylon is thin, pale tan and made of many papery layers rolled like a cigar, and it crumbles between your fingers. Powder is much harder to judge, which is the best argument for buying whole quills.
Which dalchini is sold in Pakistani and Indian shops, Ceylon or cassia?
Mostly cassia. Both are called dalchini, so the name on the packet won’t tell you. If the quills are thick, hard and dark, you have cassia; true Ceylon is usually sold separately, labelled as such, and costs more.
Can I drink cinnamon tea every day?
One cup a day is the usual household rhythm, made from a 3 to 5 cm quill simmered in 250 ml water for about 10 minutes. Choose Ceylon for a daily cup. If you’re pregnant, on diabetes medicine or blood thinners, or have a liver condition, ask your doctor before making it a habit.
Is cassia cinnamon harmful?
In normal cooking amounts, cassia is ordinary food people have used for centuries. It naturally contains more coumarin than Ceylon, which is why large daily intakes are best avoided, with the liver as the concern. For daily tea, switch to Ceylon.
Is dalchini good for sugar patients?
Cinnamon is popularly linked with blood sugar, but it isn’t a substitute for diabetes medicine, and a spoonful a day isn’t a plan. Used in food it’s perfectly fine. If you’re on diabetes tablets or insulin, speak to your prescriber before adding a daily cinnamon ritual, and never change your medicine on your own.
Does cinnamon water help with weight loss?
Not directly, and a cinnamon drink doesn’t shift weight on its own. What it can do is taste pleasantly sweet without sugar, which helps if it replaces a sugary chai. We weigh up the popular combination in dalchini and green tea for weight loss.
Is cinnamon safe during pregnancy?
Cinnamon in cooking amounts is ordinary food. Daily concentrated cinnamon drinks or supplements aren’t something to start in pregnancy or while breastfeeding without asking your own doctor.
How much cinnamon is too much in a day?
If you’re measuring it in tablespoons, that’s too much. Normal use is one 3 to 5 cm quill per family pot, or a quarter to half a teaspoon of powder in a dish or drink. With cassia, keep to those culinary amounts because of its coumarin.
Is Ceylon cinnamon worth the extra money?
For occasional cooking, cassia is fine and actually holds up better in a long stew. If cinnamon tea is a daily habit, buy Ceylon, because that’s where the difference counts.
Can I put cinnamon on my face or use cinnamon oil?
Cinnamon is one of the more common skin irritants in the spice rack, so be careful. Patch test any honey and cinnamon mask on your forearm for 24 hours first. Leave cinnamon essential oil alone; it can irritate or burn skin and mouth, and should never go neat on a toothache.
Is the cinnamon challenge dangerous?
Yes, genuinely. Swallowing a spoonful of dry cinnamon powder can send it into the lungs and has caused serious harm. It isn’t a harmless prank, so tell teenagers in the house why they shouldn’t try it.
How long does cinnamon last?
Whole quills, sealed and kept away from the cooker, stay good for two years or more. Ground cinnamon is tired in four to six months once opened and pointless after a year. Rub a pinch between your palms: if you have to hunt for the smell, it’s past it.
How do I grind cassia without wrecking my grinder?
Wrap the quill in a cloth and break it with a rolling pin first, then pulse it in a sturdy spice grinder. A mortar alone rarely wins against cassia. Grind only a week’s worth at a time.
Can I reuse a cinnamon stick?
Once, at a push. Rinse it, dry it and use it in the next pot the same day. By the second reuse it gives colour and very little smell.
