Overview

Overview Information

Cassia cinnamon is a type of cinnamon. It is prepared from the dried inner bark of a certain evergreen tree. 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.

Cassia cinnamon is most commonly used for diabetes. It is also used for prediabetes, gas (flatulence), obesity, and many other conditions, but there is no good scientific evidence to support these uses.

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.

Side Effects

Side Effects & Safety

When taken by mouth: Cassia cinnamon is LIKELY SAFE when taken by mouth short-term. Doses of 1-6 grams of cassia cinnamon have been safely used daily for up to 6 weeks. The lower doses (1-2 grams daily) have been safely used for slightly longer (up to 3 months). Cassia cinnamon is POSSIBLY UNSAFE when taken by mouth in large amounts for a long period of time. Cassia cinnamon contains a chemical called coumarin. Taking large amounts of coumarin can cause liver injury in some people, especially those who are sensitive. However, for most people, the amount of cassia cinnamon used will not provide enough coumarin to cause serious side effects.

When applied to the skin: Cassia cinnamon is POSSIBLY SAFE when applied to the skin in the short-term. It might cause skin irritation and allergic skin reactions.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking Cassia cinnamon if you are pregnant or breast feeding. Stay on the safe side and avoid use.

Children: Cassia cinnamon is POSSIBLY SAFE when taken by mouth appropriately. One gram of cassia cinnamon daily has been used safely in teens for up to 3 months.

Diabetes: Cassia cinnamon can lower blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully, if you have diabetes and use cassia cinnamon in amounts larger than the amounts normally found in food.

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

Surgery: Cassia cinnamon might lower blood sugar and might interfere with blood sugar control during and after surgery. Stop taking cassia cinnamon as a medicine at least 2 weeks before a scheduled surgery.

!

  • Medications for diabetes (Antidiabetes drugs) interacts with CASSIA CINNAMON

    Cassia cinnamon might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking cassia cinnamon along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.<br /><br /> Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

  • Medications that can harm the liver (Hepatotoxic drugs) interacts with CASSIA CINNAMON

    Taking very large doses of cassia cinnamon might harm the liver, especially in people with existing liver disease. Taking large amounts of cassia cinnamon along with medications that might also harm the liver might increase the risk of liver damage. Do not take large amounts of cassia cinnamon if you are taking a medication that can harm the liver.<br /><br /> Some medications that can harm the liver include acetaminophen (Tylenol and others), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), fluconazole (Diflucan), itraconazole (Sporanox), erythromycin (Erythrocin, Ilosone, others), phenytoin (Dilantin), lovastatin (Mevacor), pravastatin (Pravachol), simvastatin (Zocor), and many others.
