Carnosic acid is a natural benzenediol abietane diterpene found in rosemary (Rosmarinus officinalis) and common sage (Salvia officinalis).[1] Dried leaves of rosemary or sage contain 1.5 to 2.5% carnosic acid.

Carnosic acid is used as a preservative or antioxidant in food and nonfood products (e.g. toothpaste, mouthwash and chewing gum -in which it has an antimicrobial effect on the microbes responsible for bad breath- or skin care products).[citation needed]
