In a medical magazine at the doctors office. The magazine was proclaiming the ability of cinnamon to lower blood sugar. I drink coffee every day so I just made it a part of my morning regiment to add cinnamon to my coffee. And it is a natural sweetner. Cinnamon is some kind of bush or tree bark. I learned a lot from the article. But have forgotten most of it by now.
BTW, I have tested to see if it makes a difference or not and it does make about a 20% difference for my type 2 diabetes. But you gotta be careful with Cinnamon because the article said it can become toxic. I use about a half of a teaspoon every morning in my coffee.
