It also makes a great room freshener because of its strong aroma. Cinnamon blends well with Frankincense, Lavender and Onycha (Benzoin).
Because of its high phenol content, it is best diluted (1 drop to 40 or 50 drops of a quality oil, such as extra-virgin olive oil) before apply on the skin. If the mixture is too hot, apply additional diluting oil.
