Cinnamon is a type of tree that grows in tropical climates, especially India, Indonesia, Brazil and Vietnam. Cinnamon can be used to add flavor to foods or as a nutritional supplement for its potential health benefits. Cinnamon comes in a variety of forms, including cinnamon powder, tablets and oil. If you are taking cinnamon for health, talk to your doctor first due to the potential risk of developing adverse effects of taking too much of it.
Antioxidants
Cinnamon possesses antioxidant activity, according to a 2005 study published in the "Journal of Agricultural and Food Chemistry." According to a 2010 study published in the journal, "Critical Reviews in Food Science and Nutrition," in addition to being an antioxidant, cinnamon has anti-inflammatory, antimicrobial and antitumor properties as well. Most of the studies regarding the effects of cinnamon have been on small numbers of subjects and more research is needed on larger groups of people to fully assess its effects in humans.
Disease Prevention
The antioxidant activity of cinnamon can decrease the risk factors associated with diabetes and cardiovascular disease in people who are pre-diabetic or are obese, according to a 2009 study published in the "Journal of the American College of Nutrition." Cinnamon extracts can help lower blood pressure and reduce body fat, according to a 2006 study published in the "Journal of the International Society of Sports Nutrition."
Other Effects
According to the book, "Cinnamon and Cassia," cinnamon has been used in home remedies for centuries to relieve a large variety of conditions. In India, cinnamon is widely used to relieve symptoms associated with the common cold, including headaches and sore throats. Cinnamon powder can also be taken with water after meals to reduce flatulence and indigestion. More scientific evidence regarding the use of cinnamon as a home remedy is needed to verify these claims.
Precautions
Cinnamon is generally regarded as safe when used in amounts commonly found in foods, according to the Drugs.com. Some people may be sensitive to compounds contained within cinnamon, especially the plant chemical, coumarin. High doses of coumarin may worsen liver disease in people who are sensitive to it. When cinnamon comes in contact with your skin, it may cause skin irritation and allergy symptoms. Because of cinnamon's ability to lower blood sugar, it is important to monitor your blood sugar levels if you have diabetes and supplement with cinnamon.
