Cinnamon oil is a concentrated essential oil pressed from the bark or leaves of cinnamon trees. People use it in diffusers and topical blends, not as a spice you eat. The high cinnamaldehyde content makes it far stronger than ground cinnamon.
Inhaling the oil through a diffuser can help sharpen focus and lift mood. Diluted with a carrier oil, it provides a warming sensation that soothes sore muscles and joints.
This oil demands careful handling. Always dilute it with a carrier oil before putting it on skin, or you risk irritation and burns. Keep it away from eyes and mucous membranes. Do not swallow it unless a qualified professional directs you. Concentrated cinnamon oil is toxic when taken internally.
