    CASSIA CINNAMON Overview Information

    Cassia cinnamon is a type of cinnamon prepared from the dried inner bark of an evergreen tree that grows in areas of southeastern Asia. In addition to cassia cinnamon, Cinnamomum verum (Ceylon cinnamon) is commonly used. The cinnamon spice found in food stores might contain both of these types of cinnamon. But, the most common cinnamon sold in North America is cassia cinnamon.

    People take Cassia cinnamon by mouth for diabetes, gas (flatulence), muscle and stomach spasms, preventing nausea and vomiting, diarrhea, infections, the common cold, and loss of appetite.

    Some people use it for erectile dysfunction (ED), hernia, bed-wetting, joint pain, menopausal symptoms, menstrual problems, and to cause abortions. Cassia cinnamon is also used for chest pain, kidney disorders, high blood pressure, cramps, and cancer.

    People apply cassia cinnamon to the skin to repel mosquitos.

    In food and beverages, cassia cinnamon is used as a flavoring agent.

    How does it work?

    Cassia cinnamon contains hydroxychalcone and similar chemicals. These chemicals seem to improve insulin sensitivity. Cassia cinnamon also contains chemicals that may activate blood proteins that increase blood sugar uptake. These effects may improve blood sugar control in patients with diabetes. Cassia cinnamon also contains cinnamaldehyde. This chemical might have activity against bacteria and fungi. It also seems to stop the growth of some types of solid tumor cells.

    CASSIA CINNAMON Uses & Effectiveness What is this?

    Insufficient Evidence for:

    • Diabetes. There is inconsistent evidence on the effectiveness of cassia cinnamon for treating diabetes. Some research shows that taking cassia cinnamon daily for up to 3 months helps control blood sugar and reduces cholesterol and blood pressure in people with type 2 diabetes. However, other research shows that it has no effect on these measurements in people with type 2 diabetes. Reasons for the conflicting results are not entirely clear, but may relate to the dose, duration of treatment, severity of diabetes before treatment, or concurrent use of antidiabetes medications during treatment. Cassia cinnamon does not appear to improve blood sugar control and related symptoms in people with type 1 diabetes.
    • Mosquito repellent. Early research suggests that applying cassia cinnamon oil cream to the skin can protect against mosquito bites. But, it seems to decrease in effectiveness faster than creams containing citronella and geranium oils or DEET.
    • Loss of appetite.
    • Muscle and stomach spasms.
    • Intestinal gas.
    • Nausea and vomiting.
    • Diarrhea.
    • Common cold.
    • Erectile dysfunction (ED).
    • Bed wetting.
    • Joint pain.
    • Menopausal symptoms.
    • Menstrual problems.
    • Chest pain.
    • High blood pressure.
    • Kidney problems.
    • Cancer.
    • Other conditions.
    More evidence is needed to rate the effectiveness of cassia cinnamon for these uses.
