Bests & Worsts Reviews from Amazon

There are 4 primary sources for cinnamon used in cooking. Ceylon cinnamon is "true" cinnamon and is not toxic, the Saigon, Cassia and Burmannii contain high amounts of coumarin (1200x the amount of ceylon) a toxic compound that affects the nervous system. Simply organic uses the latter of the four because it is cheap do to having an extremely low oil content. Basically it is junk. If your cinnamon is bitter and not sweet (and this is) it is toxic. So just because it is "organic" does not mean it is good for you. I bought some hoping that it was right because none label their sources and am severely disappointed. On a side note the same is true of imitation vanilla having dangerously high amounts of coumarin from using the Tonka do to the fact it contains a lot of vannillan.
