The oily component of this aromatic spice is very high in cinnamaldehyde, a compound scientists believe is responsible for most of cinnamon's powerful effects on health and metabolism. A study comparing 26 spices placed cinnamon at the top for its high amount of antioxidants, surpassing garlic and oregano. Its anti-inflammatory properties may prevent the formation of free radicals that damage your cells and nervous system, and also help to reduce cholesterol levels. It is often used in keema (an Indian spiced lamb), chicken dhansak (an Indian curry) and namkeens (Indian savoury snacks)
