Its evocative name—from the Latin, ros, or dew, and mare, sea—means dew of the sea. And like a gift from the sea, essential oil of rosemary, distilled from the leaves and flowers of a small evergreen that grows in Mediterranean countries, has long had fabled powers. In ancient Greece, it was burnt at shrines to ward off evil spirits and worn by scholars as wreaths in their hair–for clarity of thought. Today, rosemary is prized as an antioxidant and stimulant that is especially beneficial to hair and scalp. A light-textured tonic with antiseptic powers and a fresh-pine aroma, it works to help clean out the pores, stimulate the scalp, and promote hair health and growth.
