Although available throughout the year, the fragrant, sweet and warm taste of cinnamon is a perfect spice to use during the winter months.

Cinnamon has a long history both as a spice and as a medicine. It is the brown bark of the cinnamon tree, which is available in its dried tubular form known as a quill or as ground powder. The two varieties of cinnamon, Chinese and Ceylon, have similar flavor, however the cinnamon from Ceylon is slightly sweeter, more refined and more difficult to find in local markets.

Recent studies have found that cinnamon may have a beneficial effect on blood sugar.

One of the first human studies was published in 2003 in a medical journal called Diabetes Care. Sixty people with type 2 diabetes took 1, 3, or 6 grams of cinnamon in pill form daily, an amount roughly equivalent to one quarter of a teaspoon to 1 teaspoon of cinnamon.

After 40 days, all 3 amounts of cinnamon reduced fasting blood glucose by 18 to 29%, triglycerides by 23 to 30%, LDL cholesterol by 7 to 27%, and total cholesterol by 12 to 26%.

In a study at Copenhagen University, patients given half a teaspoon of cinnamon powder combined with one tablespoon of honey every morning before breakfast had significant relief in arthritis pain after one week and could walk without pain within one month.

When added to food, it inhibits bacterial growth and food spoilage, making it a natural food preservative.

One study found that smelling cinnamon boosts cognitive function and memory.

Researchers at Kansas State University found that cinnamon fights the E. coli bacteria in unpasteurized juices.

   Cinnamon’s antimicrobial properties are so effective that recent research demonstrates this spice can be used as an alternative to traditional food preservatives. In a study, published in the August 2003 issue of the International Journal of Food Microbiology, the addition of just a few drops of cinnamon essential oil to 100 ml (approximately 3 ounces) of carrot broth, which was then refrigerated, inhibited the growth of the food borne pathogenic Bacillus cereus for at least 60 days. When the broth was refrigerated without the addition of cinnamon oil, the pathogenic B. cereus flourished despite the cold temperature. In addition, researchers noted that the addition of cinnamon not only acted as an effective preservative but improved the flavor of the broth.

  Cinnamon’s unique healing abilities come from three basic types of components in the essential oils found in its bark. These oils contain active components called cinnamaldehyde, cinnamyl acetate, and cinnamyl alcohol, plus a wide range of other volatile substances.

Anti-Clotting Actions

Cinnamaldehyde (also called cinnamic aldehyde) has been well-researched for its effects on blood platelets. Platelets are constituents of blood that are meant to clump together under emergency circumstances (like physical injury) as a way to stop bleeding, but under normal circumstances, they can make blood flow inadequate if they clump together too much. The cinnaldehyde in cinnamon helps prevent unwanted clumping of blood platelets. (The way it accomplishes this health-protective act is by inhibiting the release of an inflammatory fatty acid called arachidonic acid from platelet membranes and reducing the formation of an inflammatory messaging molecule called thromboxane A2.) Cinnamon’s ability to lower the release of arachidonic acid from cell membranes also puts it in the category of an "anti-inflammatory" food that can be helpful in lessening inflammation.

Cassia cinnamon, the kind of cinnamon normally found in grocery stores and in supplement form, naturally contains a compound called coumarin. Coumarin is also found in other plants such as celery, chamomile, sweet clover, and parsley.

At high levels, coumarin can damage the liver. Coumarin can also have a "blood-thinning" effect, so cassia cinnamon supplements shouldn’t be taken with prescription anti-clotting medication, such as Coumadin (warfarin), or by people with bleeding disorders.
