- Rosemary (Rosmarinus officinalis) is a common evergreen shrub grown in many parts of the world. The fresh and dried leaves are used as a food preservative and in traditional Mediterranean cuisine as a flavoring agent. Historically, rosemary has been used medicinally to treat renal colic and dysmenorrhea (painful menstruation). It has also been used to relieve symptoms caused by lung or breathing (respiratory) disorders and to stimulate the growth of hair. Today, extracts of rosemary are often used in aromatherapy to treat anxiety-related conditions and to increase alertness.
- Well-conducted human trials investigating rosemary are lacking. Rosemary appears to hold promise in the improvement of mental state when used in aromatherapy and as a treatment for alopecia. Rosemary leaf is approved by Germany's Commission E for the treatment of dyspepsia, and rosemary oil (used externally) is approved for joint pain and poor circulation.
