Prof. Benjamin Murphy, Ph.D.Cinnamon has numerous health benefits, but can be hazardous to some individuals. It's essential to know who should not use it or limit the quantity used, as serious health problems can result. Certain diseases and life stages require special care. I have counseled clients who have had difficulties with the improper use of cinnamon. This section provides a brief overview of the key groups of individuals who require special care.
Individuals with liver conditions should completely avoid cinnamon. Cassia cinnamon contains high levels of coumarin, which puts stress on the liver. Ceylon cinnamon also places added stress on the liver, even for those with an already compromised liver. I have observed improvements in liver enzyme levels in my clients who have eliminated cinnamon from their diets. Alternative spices, such as ginger, can be used for taste, without the risk associated with cinnamon.
Safe Practices
- Type selection: Use Ceylon only
- Amount limit: Under 1g daily
- Form: Culinary use in cooked foods
Avoid Completely
- Cassia cinnamon: High coumarin risk
- Supplements: Unregulated concentrations
- Essential oils: Potential uterine effects
Taking medications creates a risk of serious interactions. Blood thinners, such as warfarin, have significant hazards when combined with cinnamon. In addition, drugs used for diabetes may produce hypoglycemia. Discuss the use of cinnamon with your doctor when they prescribe the medication. I suggest keeping a medication-cinnamon log if you are taking both.
Individuals with cinnamon allergies should avoid it completely. Symptoms may include swelling of the mouth or digestive difficulty. Patch testing is done to confirm sensitivity. Other flavors to consider are nutmeg or cardamom. Attention should be paid to labels, as cinnamon may be included in spice mixes that are not expected.
Dosage Guidelines
- Age 2-4: Pinch of powder
- Age 5-12: 1/4 teaspoon max
- Teens: 1/2 teaspoon maximum
Application Methods
- Baked goods: Incorporated fully
- Oatmeal: Well mixed

Be extremely cautious if you belong to any of these groups. Speak to your healthcare provider before using cinnamon. Start with small amounts and observe how your body responds. Use Ceylon cinnamon whenever possible to reduce the chances of problems. These precautions help ensure that you benefit from using cinnamon.
