Facts about Rosemary Essential Oil
The name rosemary comes from the Latin words ros, which means “mist” or “dew,” and marinus, which means “sea.” Wild rosemary often grows on sea cliffs in France, Greece, Spain, and Italy, and is widely used in the Mediterranean region cusine.
Rosemary belongs to the mint family, along with oregano, basil, and lavender. Rosemary actually looks a lot like lavender with leaves like flat pine needles. Both have a woody, evergreen, and citrus-like fragrance that has become a pleasant feature in gardens and kitchens around the world.
Rosemary has an antioxidant ORAC (oxygen radical absorbance capacity) value of 33,000, which is the same free radical-fighting power as goji berries. Carnosol is a phenolic diterpene found in rosemary that is responsible for its antioxidant abilities.
Carnosol has had positive results against leukemia, prostate cancer, lung cancer, liver cancer, skin cancer, breast cancer, and colon cancer. Carnosol can also improve prostate health and hair growth through the reduction of DHT (dihyroxytestosterone), reduce inflammation, heal nerve tissue, and balance estrogen and androgen levels in the body.
There are somewhere between 400 and 500 phytochemicals in rosemary essential oil, and some of its major constituents include camphor, beta-pinene, alpha-pinene, 1,8-Cineole, borneol, camphene, limonene, betulinic, rosmanol, carnosol, carnosic acid, and rosmarinic acid.
5 Health Benefits of Rosemary Essential Oil
In the 16th century, rosemary was used to kill germs as a disinfectant. Rosemary oil contains expectorant, antioxidant, antifungal, anti-inflammatory, anti-infection, anti-catarrhal, anti-cancer, antibacterial, and analgesic properties. Rosemary essential oil may have the potential to increase circulation, boost immunity, treat headaches, relieve coughs, cold and flu, prevent Alzheimer’s disease and mental fatigue, and treat indigestion symptoms.
Here are five other reported health benefits of rosemary essential oil:
1. Relieves Stress and Reduces Cortisol
Rosemary essential oil may be perfect for stress relief and anxiety. In a study published in 2007 in the journal Psychiatry Research, Japanese researchers found that five minutes of breathing in lavender and rosemary would help reduce salivary cortisol levels in 22 healthy volunteers. The researchers also found the antioxidants in both oils would enhance the body’s ability to protect against free radical scavenging oxidative stress. Excess cortisol can lead to oxidative stress, high blood pressure, weight gain, and heart disease. A 2009 study published in the journal Holistic Nursing Practice also found that rosemary oil and lavender oil would reduce anxiety for nursing students taking tests.
2. Improves Memory
Ancient Greek students wore garlands of rosemary on their heads when studying to improve memory, so rosemary has long been revered for its ability to treat mental fatigue and improve focus, alertness, and mental clarity. A study published in the International Journal of Neuroscience in 2003 found that the aroma of rosemary can significantly improve memory and alertness in healthy adults. Another study published in the journal Psychogeriatrics in 2009 concluded that the scent of rosemary essential oil has potential for improving cognitive function, especially in Alzheimer’s disease patients.
3. Benefits Hair Growth
When rosemary essential oil is applied to the scalp, it may help stimulate hair growth, prevent baldness, and fight dandruff. A study published in the journal SkinMed in 2015 found that after six months of use, rosemary essential oil is equal in effectiveness to the common hair loss drug minoxidil.
4. Promotes Gallbladder Function and Liver Detoxification
Rosemary is said to be a fantastic detoxifier, and traditionally has been used for gastrointestinal issues. In India, studies have found that rosemary enhances bile flow, which is necessary for detoxification and fat metabolism. Rosemary may also lower plasma liver enzymes. Also, by enhancing bile performance, this promotes proper peristaltic gallbladder activity. This process boosts nutrient absorption and helps prevent and reverse toxic overload in the digestive organs. For improving gallbladder function, combine three drops of rosemary oil with a quarter teaspoon of coconut oil and rub it over the gallbladder area twice daily.
5. Reduces Inflammation
In a 2000 study, Brazilian researchers found that the 1,8-Cineole in rosemary essential oil has anti-nociceptive and anti-inflammatory properties. Another Iranian animal study from 2011 found that rosemary essential oil and its anti-inflammatory properties can remedy against inflammatory bowel diseases like ulcerative colitis. The scientific advisory board, called the German Commission E, has approved rosemary essential oil for treating arthritis and muscle pain. Rosemary oil may also help get rid of acne, stretch marks, and cellulite.
