Ceylon Cinnamon vs Cassia: How to Identify True Cinnamon
Short answer: Ceylon cinnamon (Cinnamomum verum), also called true cinnamon, comes mainly from Sri Lanka. It has thin, papery, many-layered quills, a sweet delicate taste and only trace amounts of coumarin. Cassia (Cinnamomum cassia and related species) has a thick, hard single layer, a strong spicy taste and much more coumarin. For daily use — cinnamon tea, oats, desserts — Ceylon is the better choice.
- Most low-cost 'cinnamon' or karuvapatta sold loose in India is cassia, not Ceylon.
- Ceylon quills are soft, thin and rolled in many layers like a cigar; cassia is a thick hard bark.
- Cassia is naturally much higher in coumarin, which can be a concern when eaten in large amounts every day.
- Use Ceylon for daily drinks and sweets; small amounts of cassia in occasional biryani are a traditional use.
- Store quills whole in an airtight jar and grind fresh for the best aroma.

The 30-second home test
- Look at the end of the stick. Ceylon shows many thin layers rolled inside each other. Cassia shows one thick curl, often hollow.
- Try to snap it. Ceylon breaks and crumbles easily between your fingers. Cassia is woody and hard.
- Smell and taste a tiny piece. Ceylon is sweet and gentle. Cassia is sharp and hot.
- Check the colour. Ceylon is pale tan-gold. Cassia is darker red-brown.
Why coumarin matters
Coumarin is a natural plant compound. Food-safety authorities in Europe have set a tolerable daily intake for coumarin because very high, regular intake has been linked to liver stress in sensitive people. Cassia can contain far more coumarin than Ceylon, so a person who drinks strong cinnamon water or takes spoonfuls of cassia powder every day could exceed that limit. Ceylon contains only traces, which is why it is the preferred cinnamon for daily use.
This does not mean cassia is dangerous in a biryani. Normal, occasional cooking amounts are a long tradition. The concern is regular, large daily amounts.
How to use Ceylon cinnamon at home
- Cinnamon tea: simmer a 2–3 cm piece of Ceylon quill in a cup of water for 5 minutes; add a squeeze of lemon or a little honey once warm, not boiling.
- Kerala payasam: add a small piece with cardamom for a soft, sweet aroma.
- Breakfast: a pinch of freshly ground Ceylon on oats, banana or Nuttb Honey Nuts.
- Baking: Ceylon gives cakes and cookies a gentle, bakery-style flavour.
- Biryani & ghee rice: Ceylon works too — use a slightly bigger piece, as it is milder.
How to store cinnamon quills
Keep whole quills in an airtight glass jar away from the stove, sunlight and steam. Whole quills keep their aroma much longer than powder. Grind only what you need for a week. If the quill has no smell when broken, it is past its best.

Is the karuvapatta sold in Indian shops Ceylon cinnamon?
Usually not. Most loose karuvapatta and low-cost 'cinnamon' in India is cassia. Look for thin, many-layered, easily crumbling quills to identify Ceylon.
Which cinnamon is best for daily cinnamon tea?
Ceylon cinnamon, because it contains only trace amounts of coumarin and has a gentle, sweet taste.
Is cassia cinnamon harmful?
Occasional use in normal cooking amounts is traditional. The concern is large amounts every day, because cassia is naturally much higher in coumarin.
How can I identify Ceylon cinnamon powder?
It is harder with powder. Ceylon powder is lighter tan and smells sweet and mild; cassia powder is darker and sharper. Buying whole Ceylon quills and grinding at home is the surest way.
Why is Ceylon cinnamon more expensive?
It is harvested from thin inner bark and rolled by hand into layered quills, which takes more skill and time than cassia.
