I really wanted to make a "cinnamon roll" scented lip balm, so decided to try this oil out as an addition since cinnamon flavors can be hard to find. As the description states, this stuff is really potent! Cassia can also be a little irritating to the lips if too much is used. I used only 1-2 drops in a batch of roughly 1.5oz of balm, and that seemed to work well for me without being irritating or too overpowering with my vanilla scents. Would highly recommend! Just make sure to follow the advice in the description.
