Cinnamon improves taste and aroma, in addition to being antimicrobial and a modest pain reliever. The inner bark is the part of the plant from which either the powder or the more concentrated oil is derived, and is the only part approved for use as a medicinal herb by the prestigious German Commission E.
Cinnamon has properties that are antimicrobial, antiviral, antifungal, and slightly anesthetic, which can be beneficial for sore tissues. The oil and bark have been traditional folk remedies for many years. For example, the oil was listed as part of the household inventory of herbal medicines in 1834 of Maryland's Homewood House, built by one of the signers of the Declaration of Independence. It has historically been used to numb teeth and gums, including the gums of teething infants.
Cinnamon is also considered one of the most concentrated sources of antioxidants.
Cinnamon is not only a natural dental care product, other traditional applications for cinnamon (other than for the teeth, gums and mouth) address the digestive process, including indigestion, loss of appetite, bloating, and flatulence.
