>>990598>>990608It comes from the inner bark of an evergreen tree originally from Sri Lanka. Madascar and Mexico now grow it too. The scientific name is "Cinnamomum verum" aka Ceylon Cinnamon "real cinnamon". It is pretty expensive too ($15-$25 per pound of sticks). Everything else is a more toxic variety from other parts of the world. The toxic ones contain coumarin. C. verum has a tiny tiny amount of this, but the most common cinnamon used in the USA is C. cassia which contains the most toxin. Eating as little as 1-2 teaspoons in a day will make you overdose on the toxin. This is easy to do when you are eating lots of foods that contain cinnamon (holiday meals/) in them or are taking cinnamon supplements. The FDA doesn't have control limits on coumarin, but the European Union does.
The real cinnamon is less spicy and more aromatic and sweet.
