have to use it in moderation....its a double edge sword the coumarin is toxic to your liver and kidneys,but also has some medical benefits.
as little as 1 teaspoon daily can be toxic to your liver if your taking the cassia cinnamon,which is what is mostly sold in stores,most brands wont list what type, celyon can only be bought in specialty shops and online,or in Mexico usually,you can kinda tell the diff, cassia is more spicy like has that kick to it, celyon is more sweet and lacks the kick, its probably why cassia is more popular,the toxic coumarin is what gives it its kick.
cassia cinnamon has high amounts of Coumarin which has shown to cause liver inflammation & damage,Ceylon cinnamon has way less amounts of coumarin.
High daily intakes of cinnamon: Health risk cannot be ruled out

Frequently Asked Questions about coumarin in cinnamon and other foods:
http://www.bfr.bund.de/cm/279/freque...ther_foods.pdf
Can too much coumarin damage health?
From the use of coumarin in the medicinal field, it is common knowledge that relatively low doses can already cause liver damage in a small group of particularly sensitive individuals if the medicinal products are administered over a few weeks. In minor cases this leads to an elevation of liver enzymes in blood, in severe cases to inflammation of the liver which manifests as jaundice. The exact mechanism of action is not known but the effects are reversible.
Can coumarin induce tumours?
In animal experiments very high levels of coumarin administered over long periods did trigger cancer in rats and mice. For humans there are no reports of coumarin-related tumour formation.
Should a consumer who regularly eats larger amounts of cinnamon biscuits expect damage to his health?
Consumers who have eaten large amounts of cinnamon in the past have no reason to worry that their liver has suffered permanent damage. The liver of patients who developed minor to moderate liver inflammation caused by the administration of coumarin recovered fully just a few weeks after the medication was discontinued.
