Cinnamon Bark Essential Oil is steam distilled from the bark of the cinnamon tree. The bark oil is generally preferred over Cinnamon Leaf Essential Oil. However, oil distilled from cinnamon bark tends to be much more costly than that distilled from the leaves. Aromatically, Cinnamon Bark Essential Oil is much richer in aroma than ground cinnamon. Cinnamon Bark Oil tends to be warming, stimulating and energizing. It blends well with many other essential oils especially oils in the wood, spice, citrus and mint families Appearance Dark Yellow Clear Oily Liquid Specific Gravity 1.01000 To 1.03000 @ 25.00 °c Pounds/gallon 8.404 To 8.571 Refractive Index 1.57300 To 1.59100 @ 20.00 °c Boiling Point 249.00 °c. @ 760.00 Mm Hg Flash Point 160.00 °f.
