The Ancients were well acquainted with the shrub, which had a reputation for strengthening the memory. On this account it became the emblem of fidelity for lovers. It holds a special position among herbs from the symbolism attached to it. In the West, not only was it used for ornamentation at weddings, but also at funerals, for decking churches and banqueting halls at festivals, as incense in religious ceremonies, and in magical spells. At weddings, it was entwined in the wreath worn by the bride, being first dipped into scented water. The herb, aerial parts of rosemary and the roots are the most commonly used parts for its medicinal and commercial applications.
Research conducted at the University of California’s San Diego School of Medicine and Biofinity on participants in the age group 60 to 90 years or older have demonstrated that people who use this herb regularly have had virtually no cataracts, very few bone fractures, excellent heart health and significantly low rates of Alzheimer’s disease. The older residents who use the herb have exceptionally good microcirculation.
Ayurveda makes use of Rosemary essential oil for improving memory, Halitosis, headaches, stomach upset, insect bites, skin problems like eczema and skin infections. AcneFoundation.org writes that Rosemary happens to be one of the key ingredients in the manufacture of their products. Ayurveda also uses Rosemary essential oil for aromatherapy treatments. When used as an essential oil, Rosemary is excellent tonic for skin and hair, augments memory, fights depression, fear and fatigue, and on the whole, is a ‘must-have’ essential oil in the medicine cabinet. Rosemary essential oil can help address a wide variety of health issues including dental problems, respiratory disorders, inflammation and pain, urinary problems, gastrointestinal troubles and weak immune system.

However, taking higher doses (150-6000 mg) seems to make memory worse. There is also early evidence that suggests rosemary aromatherapy can improve the quality but not the speed of memory. Evidence about the effects of rosemary aromatherapy for anxiety and stress is mixed although it suggests that rosemary and lavender oil may reduce heart rates.
Dermatological/Skin: Applying rosemary oil with lavender, thyme, and cedarwood oils to the scalp improves hair growth. Useful in eczema.

Ophthalmic: A study published in the journal Investigative Ophthalmology & Visual Science, led by Stuart A. Lipton, M.D., Ph.D. and colleagues at Sanford-Burnham Medical Research Institute, revealed that a major component of rosemary, carnosic acid, can significantly promote eye health. This could have clinical applications for diseases affecting the outer retina, such as age-related macular degeneration - the most common eye disease in the U.S.
Other: Vulnerary, useful in promoting healing of open wounds (contusions, abrasions, lacerations and punctures). Evidence suggests that rosemary might help withdrawal from narcotics.
