Cinnamon Cassia is steam distilled from the bark of the Chinese Cinnamon tree to create a 100% pure essential oil that has absolutely no additives or fillers. This strong, scented oil is very warm and spicy like its relative cinnamon. That wonderful aroma that is familiar in the spice world, is a favorite to create seasonal blends that bring the Holidays indoors. This powerful oil can be used in a warming massage blend, but only very little is needed. Using a toothpick, you can dip the end into the orifice reducer and then swirl into your favorite Plant Therapy carrier oil for topical use. We recommend a maximum dilution of 0.05% for topical applications. This can cause skin irritation so use on a small patch of skin before applying in larger areas.
