rue cinnamon, also known as sweet cinnamon, Xi Lan Rou Gui, Ceylon, or Zeylonicum cinnamon, is a popular spice used in many versatile ways throughout history. Cinnamon is widely popular and known for its slightly sweet, delicious, and spicy warming flavor commonly found in baked goods, teas, and spice mixes. True cinnamon has a more subtle, delicate, and less sweet flavor than the closely related cassia cinnamon. Cinnamon, along with it's exceptional and unique flavor, is a highly valued and multipurpose medicinal herb used for circulatory, respiratory, and expectorant applications. It is also used to aid in the digestive process and enhance metabolic function. Many cultures have used cinnamon in their health practices topically and internally throughout history.
