Oil of clove is 60 to 90 percent eugenol. A potent pain deadening antimicrobal. Clove has earned the official endorsement of the FDA as an effective stopgap measure for tooth pain. Clove is also among the spices that can help the body use insulin more effectively, thus lowering blood sugar somewhat. In one lab study, clove was also found to speed healing of the dreaded cold sores. On the ORAC (Oxygen Radical Absorbance Capacity) scale used by the National Institute on Aging in the National Institutes of Health (NIH) to assess the antioxidant value of foods, clove has the highest ORAC score.
I remember using Oil of clove for Wisdom tooth pain.
