Hello @aboutcoolscience :)
It is nice to read your work again (it has been a while!). It was only last Christmas while looking for apple + cinnamon recipes that I got a glimpse of this spice's antidiabetic properties. Like this, from your post, I found most interesting that such effects have only been seen in rats :) Goodness me, some bloggers out there really get carried away!
The background history of it it's also quite fascinating! To think one day cinnamon was more valuable than silver... I am always interested in learning about such things. Finally, in Portuguese (and Spanish) cinnamon is also called canela. But, I suspect you already knew that!
I wish you a wonderful day.
All the best to you,
Abigail
