Abstract

Addition of rosemary extract to various dentifrice compositions results in tooth paste, mouth rinses, and other compositions that are suitable for treating and preventing a variety of oral disease including gingivitis, plaque build-up, and the like. Rosemary extract, containing major amounts or ursolic acid and camosic acid, is added to dentifrice compositions so that the amount delivered to the oral cavity upon use is effective to provide an antibacterial, antioxidant, and/or anti-inflammatory effect. In various embodiments, the components of rosemary extract are combined with triclosan or other phenolic antibacterial agents to provide enhanced activity.
