Rosemary Extract Oil Profile

Rosemary Plant

The rosemary herb must be one of the most well-known and versatile herbs around, and for his reason, Rosmarinus officinalis has gained great popularity.  The cosmetic application has a variety of uses.

The therapeutic properties of rosemary include that of tonic, astringent, as well as reducing skin fragility, and are found in most of Sher-Ray Organic Cosmetic’s super serums.

Topical use includes help for healing wounds and reducing skin fragility while boosting the skin in general, since it has a great ability to increase circulation.  It also contains antioxidants which have anti-ageing properties as they reduce damage caused by free radicals.  The antioxidants contained in rosemary is the active element why it was used centuries ago to help keep meat from spoiling and to help fight infection- since the powerful antioxidant effect helps to retard oxidation and inhibits the action of some micro-organisms.

It grows as a bush of between 1.5 to 3.3 feet in height and can even grow as high as 6.5 feet.  The flowers are pale blue and gather in tiny bunches.  They have a small, bell-shaped bilabiate calix with three teeth, and the corolla is long with two very clearly marked lips, the first with two lobes and the second with three.
