Cinnamon is a spice that comes from the branches of trees of the "Cinnamomum" family. It is native to the Caribbean, South America, and Southeast Asia.
It is now the second most popular spice, after black pepper, in the U.S and Europe.
Some studies in labs and on animals have indicated that cinnamon may have some beneficial health properties, but more research and evidence is needed to confirm these benefits.
Taking cinnamon as a supplement can have effects on health and disease. Supplements, however, are not monitored by the FDA and there might be concerns about quality, purity, and strength in varying brands of any supplements.
It has also been used in traditional medicine for bronchitis.
There is a lack of evidence supporting these uses, however.
Cinnamon oil may help treat some types of fungal infections, such as Candida, according to
Consuming up to 6 grams (g) of cinnamon a day appeared to lower serum glucose, triglyceride, LDL cholesterol, and total cholesterol in 60 people with type 2 diabetes.
The authors suggested that if people with type 2 diabetes include cinnamon in their diet, this may reduce their risk of diabetes and cardiovascular diseases.
However, in a review published in 2012, researchers
Animal studies have suggested that cinnamon may help prevent Alzheimer's disease.
According to researchers at Tel Aviv University, an extract found in cinnamon bark, called CEppt,
If confirmed by further research, this extract, but not necessarily whole cinnamon, may be useful in developing therapies for Alzheimer's.
Of the 69 extracts tested in a lab, Cinnamomum cassia, or cinnamon bark, and Cardiospermum helicacabum, the cinnamon shoot and fruit, were most effective in reducing HIV activity.
This does not mean that foods containing cinnamon can treat or prevent HIV, but cinnamon extracts could one day be useful as part of a therapy.
Cinnamon has been tested for activity against multiple sclerosis (MS).
Researchers tested mice that had consumed a mixture of cinnamon powder and water. The
Studies have also suggested that cinnamon may protect regulatory T cells, known as Tregs. These are considered the "master regulator of immune responses." People with MS appear to have a lower level of Tregs than people without the condition. In mouse studies, cinnamon treatment has
Cinnamon treatment has also been found to restore myelin levels in mice with MS.

Lowering the negative effects of high fat meals
In 2011, researchers concluded that diets rich in "antioxidant spices," including cinnamon, may help reduce the body's negative response to eating high-fat meals.
Treating and healing chronic wounds
Research published in the journal ACS Nano suggests that scientists have found a way to package antimicrobial compounds from peppermint and cinnamon in tiny capsules that can both kill biofilms and actively promote healing.
In this way, peppermint and cinnamon could become part of a medicine for treating infected wounds.

- Ceylon cinnamon (Cinnamomum verum), often considered to be "true cinnamon"
- Cassia cinnamon or Chinese cinnamon (Cinnamomum aromaticum), which originates from southern China
Ceylon cinnamon is very expensive, so most foods in the United States and Western Europe, including sticky buns, breads and other products use the cheaper Cassia cinnamon (dried Cassia bark).
However, cinnamon contains coumain, a natural flavoring. Consuming too much coumarin can lead to liver damage and affect coagulation. For those on anti-coagulants or other drugs, or those who have diabetes, it is important to discuss taking cinnamon supplement with your health care provider.
Cassia cinnamon powder, commonly used in foods in the USA and Western Europe, contains more coumarin than Ceylan cinnamon powder.
A German study study published in 2010 found that coumarin content varies widely, even in samples of cinnamon from the same tree. Cassia cinnamon was particularly high in coumarin.
People with liver disease should limit their consumption of cinnamon.
Cinnamon should not be used instead of treatment for health conditions. Anyone who is considering increasing their intake of cinnamon or taking supplements should first speak to a doctor.
