Side Effects

Side Effects & Safety

When taken by mouth: Saigon cinnamon is LIKELY SAFE when taken in amounts commonly found in food. But Saigon cinnamon contains a chemical called coumarin. Coumarin has been linked with adverse effects. To avoid this risk, people should avoid taking Saigon cinnamon in doses that provide more than 0.1 mg of coumarin daily. For a person weighing 70 kg (about 154 lbs), this would be equal to about 1 gram (0.25 tsp) of Saigon cinnamon per day.

Saigon cinnamon is POSSIBLY UNSAFE when taken by mouth in large amounts for a long period of time. Taking large amounts of Saigon cinnamon may cause liver injury or worsen liver disease due to the chemical coumarin. This might be especially true in people who are sensitive to coumarin. Coumarin may cause liver injury at doses as low as 50 mg/day. For a person weighing 70 kg (about 154 lbs), this would be equal to about 7 grams of Saigon cinnamon per day.

There isn't enough reliable information available to know if Saigon cinnamon is safe or what the side effects might be when used as medicine in amounts less than 7 grams per day.

Special Precautions & Warnings

Pregnancy and breast-feeding: There isn't enough reliable information to know if Saigon cinnamon is safe to use when pregnant or breast feeding. Stay on the safe side and avoid use.

Liver disease: Saigon cinnamon contains a chemical that might harm the liver. If you have liver disease, do not take Saigon cinnamon in amounts larger than the amounts normally found in food.
