Diabetes is a long-term metabolic condition that occurs either because the body produces no insulin, or too little insulin, or the body doesn't respond to insulin properly. Diabetes can cause serious complications, including blindness, stroke and heart disease, if left untreated. Type 1 diabetes is usually treated with insulin injections, while Type 2 diabetes is often controlled through dietary measures and prescription medicines that regulate blood glucose levels. Cinnamon is sometimes used as an alternative medicine for Type 2 diabetes, although evidence to prove it works is limited. Don't take it in place of medicines prescribed by your doctor, and get medical clearance before using it.
Properties and Potential Benefits
Cinnamon is most commonly used to flavor foods and beverages. However, it is also sometimes used as a complementary medicine for inflammation and arthritis. It contains a host of biologically active compounds, including volatile oils and compounds known as monoterpenes and sesquiterpenes. The University of Maryland Medical Center says cinnamon might also play a role in regulating blood glucose levels in patients with Type 2 diabetes.
Administration
Cinnamon commonly exists as a powder, but you might also find it in capsules or tablets. The amount you need to take to help control your blood glucose levels might vary according to your age, overall health and other medicines you might be taking. However, the Mississippi Baptist Health Systems website says the recommended dose of cinnamon is usually between 1 g and 4 g per day. Check with your doctor that these amounts are appropriate for you.
Scientific Evidence
The results of the study published in the December 2003 issue of "Diabetes Care" show that taking either 1 g, 3 g or 6 g of cinnamon daily for 40 days reduces blood glucose levels in patients with Type 2 diabetes. As such, the authors conclude that including cinnamon in the diet of people with Type 2 diabetes might help to reduce diabetes-associated complications. An analysis of data from clinical trials published in the April 2007 issue of "Pharmacotherapy" concludes that although cinnamon modestly lowers blood glucose levels in patients with poorly controlled Type 2 diabetes, clinicians should not recommend cinnamon supplements in place of anti-diabetic drugs and insulin.
Safety Considerations
RxList says cinnamon is likely safe for most people, but adds that taking large amounts for long periods might increase the risk of liver disease. Because cinnamon might lower your blood glucose levels, it is important to get your blood checked regularly while taking this herb to ensure your blood glucose levels don't become too low. Also bear in mind that it might heighten the effect of any anti-diabetes medicines you are taking. Don't take a cinnamon supplement if you have liver disease or if you are pregnant or breastfeeding.
