This team are making a name for themselvesYup, I have to admit, I’m amongst some major smarty-pants who also love to geek out! My colleagues and I shout down the halls in excitement to inform each other about the latest studies regarding the power of poo. In fact, sometimes I am even able to skip down the hall singing rhythms about new compounds that modulate inflammatory pathways and how polyphenols rock in helping our microbiome stay healthy. I actually get smiles, not sneers. Talk about a nerd’s heaven!

So, I was excited to read a post by some of my science-lovin’ peeps that highlighted an amazing spice, cinnamon, and its essential oil component.

I was cross-referencing studies and, in a nerdy moment, I started bonding with Google and PubMed again.

I came up with 5 pretty good reasons to make sure cinnamon oil is in your spice shelf.


1. Saving Me From Moldy Cashews!

As serendipity would have it, I was nibbling on some cashews as I was reading the cinnamon blog. I then felt a little bit “weak in the news!”

Could it be the yeast!!

It seems cashews are known for harboring aspergillus species, the nasty fungus that causes a wide-array of issues!

Thankfully, I was snacking by my computer and found an article that supported how cinnamon, thyme, garlic, mint, and rosemary inhibited growth of this microbe in a dose dependent manner. So, I grabbed my cinnamon and rubbed some on my feet. Phew!


This story may not be true at all and the names and events may be totally fabricated. This was probably done in order to share with the reader how a study could be helpful in a real life situation and to emphasize the important aspects in the study. It is also meant to portray a lesson to not eat in front of a computer. ;-D



superbugs and oils2. Getting Rid of Biofilms In Vitro

Remember how those nasty, resistant superbugs secrete materials in order to form a unified clan of misfits. These critters then bond together in our bodies and cause havoc on our health. Darn those biofilms!

Well, an in vitro study showed cinnamon oil inhibited the microbe, pseudomonas,  bugger’s biofilm. The study also exhibited it had other microbial inhibition properties.

Another study found cinnamon oil inhibited candida species biofilms too!



3. Providing Heart Relaxation To Mice

A rodent heart cell study demonstrated how one of cinnamon oil’s active constituents, cinnamaldehyde (CA), had an ability to modulate vessel relaxation. Now, this study was an in vivo trial with mice and didn’t use the intact, whole oil. This means the compound will have a more directed verses subtle and integrated response.


4. CA Induces Cell Death In Vitro

Cinnamaldehyde was also found to modulate (a lot of cool) biochemical pathways involved in apoptosis (cellular death) in a study using human cancer cells.


5. Antioxidant Properties

a. Digging deeper I found this review that discussed the antioxidant and microbe inhibiting properties of cinnamon bark oil.

b. Another study was done with rodents to determine the effect of Cinnamoum verum and cardamom on heart and liver antioxidant enzymes, glutathione (GSH) and lipid conjugated dienes. The authors concluded:

The antioxidant enzyme activities were found to be significantly enhanced whereas GSH content was markedly restored in rats fed a fat diet with spices. In addition, these spices partially counteracted increase in lipid conjugated dienes and hydroperoxides, the primary products of lipid peroxidation.

c.  Check this quote out in this study on the top antioxidant spices, “Phenolic volatile oils were the principal active ingredients in most spices.”


3 Ways Dr. Sarah Uses Cinnamon Oil

Now that we have reviewed some actions of cinnamon oil, aren’t you curious to know how to use it?

  1. I rub a drop on my feet after cashew consumption. (Pun intended)
  2. I place a toothpick amount in raw, goat yogurt.
  3. I diffuse 3 drops cinnamon, 3 drops ginger, and 1 drop lavender at night to freshen the air and calm my brain.

And remember…be safe and use with common sense!
