Ceylon cinnamon is less common and has long been prized as a cooking spice. It is quite expensive compared to the more common cassia variety.
It’s described as having a delicate and mildly sweet flavor suitable for desserts.
Approximately 50–63% of its essential oil is cinnamaldehyde, which is quite low compared to cassia. This explains its milder aroma and flavor.
Ceylon cinnamon may be used for indigestion (dyspepsia), diarrhea, diabetes, obesity, and other conditions, but there is no good scientific evidence to support these uses.
In manufacturing, cinnamon oil is used in small amounts in toothpaste, mouthwashes, gargles, lotions, liniments, soaps, detergents, and other pharmaceutical products and cosmetics.
