Wonderful!
This stuff is so strong even though I only put a few drops in a bottle of olive oil.  I love it!  Well, for some reason, I didn't realize that it isn't meant to be eaten.  But I was addicted to cinnamon sticks, and after I broke a tooth, I couldn't chew the sticks anymore.  So, I tried one drop in a cup of tea.  Wow, was that amazing.  And while I was enjoying my third or fourth cup of tea, I read the label on the PipingRock bottle.  Well, I don't know that I'm going to find food grade cinnamon oil.  If I do, I am going to bet it doesn't compare with this.  I have tried brewing my tea in a bath of cinnamon sticks.  A dozen cinnamon sticks doesn't do what one drop of this oil can do to flavor my tea.
