Yes: Cinnamon contains a natural substance, coumarin, that in very large amounts can cause bleeding and damage liver and kidneys. Ceylon cinnamon is "true" cinnamon, : but some companies use the less expensive cinnamomun aromaticum , or cassia. This contains more coumarin, and could be more problematic in large doses than ceylon cinnamon. http://tinyurl.com/qaqlu52.
