Cinnamon is a popular spice that many people enjoy in foods, drinks, and even scented candles. While a little cinnamon can add great flavour to your day, too much of it may cause problems. The good news is you don't have to avoid cinnamon completely. Just use it in moderation as part of a balanced diet. Enjoy cinnamon's aroma and taste but stick to small portions. 

Cinnamon, that familiar warm-toned spice found in everything from apple pie to chai tea, has a fascinating history and journey to the kitchen. Native to Sri Lanka, cinnamon comes from the inner bark of Cinnamomum trees. Skilled harvesters carefully peel away the bark, which curls into quills as it dries. Cinnamon's sweet, woody, slightly spicy flavour comes from the compound cinnamaldehyde.   

Cinnamon has been prized for its aroma, flavour, and preservative properties. Today it remains a beloved ingredient around the world. Sprinkled on oatmeal, blended into chai tea, or swirled into baked goods, cinnamon's warmth shines through in both sweet and savoury dishes.

Why Too Much Consumption Of Cinnamon Harmful 

There are four main varieties of cinnamon: Ceylon, Cassia, Saigon, and Korintje. Ceylon cinnamon has a delicate, complex flavour perfect for desserts. The more pungent Cassia cinnamon is better suited to savoury dishes. Saigon cinnamon offers a sweetness reminiscent of candy. Korintje cinnamon from Indonesia has a mild flavour great for baking. Cinnamon contains a compound called coumarin that can be harmful in large amounts. As per National Library of Medicine, consuming very high doses of coumarin could potentially lead to liver damage over time.
