What You Need to Know
The two types of cinnamon have different safety profiles. Ceylon cinnamon (true cinnamon from Sri Lanka) has negligible coumarin content and is safe in small amounts. Cassia cinnamon sold in most supermarkets as regular cinnamon has higher coumarin content that accumulates with regular large feeding causing liver toxicity. A sprinkle on food occasionally is not harmful with either type. The cinnamon essential oil used in aromatherapy and cleaning products is far more concentrated and always toxic — never use near dogs.
