Rosemary, Rosmarinus officinalis, is a small evergreen shrub grown in many parts of the world. The fresh and dried leaves are used as flavoring agents and food preservatives. Rosemary has been used for centuries as a valued herb. It contains a number of phytochemicals that demonstrate antioxidant activity, including caffeic, carnosic and rosmarinic acids 1. Rosemary is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as a spice or natural seasoning (21CFR182.10).
