The Rosemary Herb
Derived from the Latin word ros ‘dew’ and marinus ‘sea’, Rosemary (Rosmarinus officinalis) means ‘dew of the sea’. It is a perennial herb grown in many parts of the world for its multiple medicinal, aromatic and cosmetic properties.
Archaeologists and anthropologists have found evidence that rosemary herbs were used for medicinal, culinary, and cosmetic purposes in ancient Egypt, China, Mesopotamia, and India. In ancient Rome and Greece, rosemary was believed to strengthen the memory which accounts for it being known as the herb of remembrance and fidelity. Rosemary was also an essential part of the apothecary’s repertoire during the Renaissance period. Elizabethan sweethearts carried a twig of rosemary and is still used in bridal bouquets in England and Germany until today. The leaf of rosemary is an indispensable flavoring agent and spice of the French, Italian and Spanish cuisine.

These have with high antioxidant properties and are used for problems involving the central nervous system, cardio vascular system, liver treatments, and respiratory systems among many others. Rosemary leaves have been traditionally used to treat a variety of conditions including dyspepsia, headache and nervous tension.
Based on obtained scientific results, volatiles from the plant induced apoptosis at cytotoxic concentrations and indicate that consumption of the natural compounds might be valuable in the prevention of lifestyle diseases.

Health Benefits of Rosemary Essential Oils
Results of relevant studies show that there are biologically active compounds in rosemary essential oils that exhibit cytotoxic, antioxidant, anti-carcinogenic and cognition-enhancing properties depending on their type and concentration. They also have the potential to influence glucose levels in diabetic patients and enhance bone resorption.
Rosemary Essential Oil for Hair Growth
One of the known benefits of rosemary oil is its capability to enhance micro-capillary perfusion (circulation). Along with cedarwood, thyme, and lavender; rosemary oil helps promote hair growth even in patients with alopecia and prevent dandruff.
Studies have investigated the clinical efficacy of rosemary oil in the treatment of androgenetic alopecia (AGA) and compare its effects with minoxidil 2%. Patients with AGA were randomly assigned to rosemary oil (n = 50) or minoxidil 2% (n = 50) for a period of 6 months.
The frequency of scalp itching at the 3- and 6-month trial points was significantly higher compared with baseline in both groups (P <.05). Scalp itching, however, was more frequent in the minoxidil group at both assessed endpoints (P <.05). The findings of the present trial provided evidence with respect to the efficacy of rosemary oil in the treatment of AGA.
An herbal hair treatment composition for controlling dandruff comprises of a cosmetically acceptable carrier and a vegetable oil extract of sage, Indian hemp, and rosemary.

Antimycotic (Anti-fungal) Activity of Rosemary Oil
The problem of yeast/fungal infection (oral candidiasis) in immuno-compromised patients and following the use of drugs such as broad-spectrum antibiotics, corticosteroids and cytotoxic drugs which may not respond to the commonly used remedies such as nystatin. Rosemary oil has been shown to remarkably inhibit the growth of infection. It has been reported that when an aqueous emulsion of rosemary oil in water (1:10) is applied with a cotton swab in the mouth, five times a day, of patients with different types of cancer and pneumonia having candidiasis which did not respond to treatment with nystatin, the growth of the yeast disappeared completely in 2-4 days.
Anti-oxidant Properties of Rosemary
It is well established that the increased formation of oxygen free radicals may cause tissue damage and degeneration and hence may play a role in the pathogenesis of some diseases and acceleration of ageing process.
Evidence suggests that maintaining high intakes of antioxidants such as vitamin E, vitamin C and some types of food constituents may help to protect against life-threatening diseases such as heart disease and cancer. Abundant antioxidant help reduce inflammation and prevent oxidative damage that leads to premature aging.
The accumulated evidence supports that rosemary is one of the important antioxidants which are commonly used in various folk medicine and as a beverage drink. It inhibits lipid peroxidation and prevents carcinogen-DNA adduct formation. Increasing utilization of this plant, which has been shown to be safe in toxicity studies in animals and when added as antioxidant to food, can be achieved simply by adding it to food for flavouring and by taking it as a drink.
One of the most important constituents of rosemary are caffeic acid and its derivatives such as rosmarinic acid. These compounds have antioxidant effects. Rosmarinic acid is well absorbed from gastrointestinal tract and from the skin.
