Even though research is ongoing and the available information is still unclear, cinnamon is used in health care products to help in lowering blood sugar in diabetics and to control yeast infections in HIV patients, as stated by WebMD. Some studies have also indicated that cinnamon can fight bacteria, and it is an antioxidant that helps to reduce inflammation. It can also be used to help lower cholesterol.
Cinnamon is commonly used as a spice for different foods. Traditionally, the extract from the bark of the cinnamon tree is used for medication purposes in many parts of the world. For people who intend to use pure cinnamon, there is no recommended dose, since cinnamon has not yet been medically proven for medication purposes. However, a doctor may advise a particular dosage for managing a certain condition. Cinnamon can be found in stores in combination of two or more other ingredients.
Proper use of cinnamon does not cause any known side effects. Overusing it may lead to irritation on the lips and mouth, and might lead to an allergic reaction in some people. If taken in heavy doses, cinnamon may be toxic, especially in patients suffering from liver problems. Diabetics may need to consult their physician to adjust their dosage if they are using cinnamon, as noted by WebMD.
