Colorful Description
What do modern medical researchers, bees, the Bible and the Queen of England have in common? Well, as you can probably guess from the topic, it is the recognition that lavender possesses exceptional properties for health and wellness. Medical researchers are now investigating the components of lavender oil that have been used for centuries as a stress and anxiety reducer, an insect deterrent and as an antiseptic and an anti-inflammatory. Honey bees have quite an affinity for the pollen of lavender plants; commercial production of lavender honey is well prized. Lavender was one of the herbs used in the biblical Temple to prepare the holy essence and mentioned in the Song of Solomon as an admirable herb. Queen Elizabeth I was known to use lavender as a tea to treat her frequent migraines. It is now recognized by the medical industry that alternatives to conventional treatments are needed and that lavender is a good candidate for safe and effective applications.
Although generally known as lavender, there are actually thirty-nine species of the genus Lavendula, yet only a handful is used commercially. This fragrant plant is native to the Mediterranean region south to tropical Africa and to the southeast region of India. Today lavender is successfully cultivated in southern Europe, Australia and the United States. Aromatherapists distinguish lavender species according to their therapeutic uses and medicinal properties. True lavender (L. officinalis, L. angustifolia) when distilled at high elevations is known for its large percentage of ester content and regarded as the best in quality. Uses for true lavender include cases involving anxiety, stress, small burns, cuts and insect bites. Spike lavender (L. spica, L. latifolia) is known for its camphor content and thus used for respiratory infections, for muscular aches and pains and as a possible stimulant. Lavendin (L.fragrans, L. burnatti) is a hybrid of true lavender (L. angustifolia) and spike lavender (L. latifolia) and commonly used for large-scale commercial purposes. Stoechas lavender (L. stoechas) is used as an expectorant and known for its antimicrobial properties.
Sedative Effects of Lavender
Lavender is well recognized as an agent able to support a reduction in anxiety, mainly due to its high linalool levels. The physiological process of reducing anxiety through the use of essential oils is quite phenomenal. Once the diffused molecules of essential oil enter the nasal cavity, they bind to receptor sites of the olfactory neurons which then trigger a cascade of events. In short, the olfactory neurons send messages to the olfactory nerve and then onto the olfactory bulb (located just three inches from the brain) where messages are initially processed. Within the olfactory bulb are input and output stations, the glomeruli and M/T (mitral and tufted) cells respectively. The olfactory output from the bulb to the brain has several targets, mainly the primary olfactory cortex and the higher olfactory associated areas where olfactory discrimination, perception and memories take place. The other is the limbic system, sometimes referred to the 'nose' brain comprising a complex system of 122 regions and associated areas which together is heavily responsible for the expression of emotion. Main structures of the limbic system (LS) are the amygdala, septum, hippocampus, anterior thalamus, and hypothalamus.
Diffused essential oil of lavender has been shown to alter reactions in the limbic system - a system that includes the amygdala and hippocampus, both of with are vital to our behavior, mood and memory. Recent studies have found lavender to reduce levels of cortisol (a hormone secreted by the adrenal glands). High and prolonged levels of cortisol have been shown to have a deleterious effect on the body, such as higher blood pressure, lowered immunity and decrease in bone density. A 2008 study published by the International Journal of Cardiology (Sep 26; 129(2): 193-7)found that lavender aromatherapy reduced serum cortisol and improved coronary flow velocity reserve (CFVR ) in healthy men after stress was induced and concludes that lavender aromatherapy has relaxation capabilities and may be beneficial for cases concerning coronary circulation. Another study from the Osaka University Graduate School of Medicine, Osaka, Japan (Archives of Oral Biology 2008 Oct; 53(10): 964-8) found that salivary cortisol levels decreased in stressed subjects (via a series of mathematical tasks) after being exposed to air-borne lavender essential oil; cortisol levels did not decrease in the control group. Lavender essential oil has also been found to help babies as well. The University of Miami Miller School of Medicine, Florida (Early Human Development 2008 Jun; 84(6): 399-41) found that babies bathed with essential oil of lavender cried less and spent more time in deep sleep than babies who were not bathed with the oil.
Other Applications for Lavender
A rather haphazard discovery of lavender in the use of tissue regeneration was made by the late Dr. Rene-Maurice Gattefosse (a French cosmetic chemist) who after he severely burned his hands in a laboratory accident, submerged them in a container of lavender essential oil and noted the remarkable speed at which they healed. More recent research has newly discovered the possible antimutagenic (inhibits mutations) effect of lavender. In this study (Food and Chemical Toxicology 2005 Sept; 4319: 1381-7) scientists noted antimutagenic effects of lavender oil (L. angustifolia) on a strain of Salmonella bacteria, concluding that such uses of lavender may be promising for applications in modern human healthcare. Other uses, such as antimicrobial and antiviral have been recognized and supported on the University of Maryland Medical Center website (www.umm.edu).
To Remember
Modern science is now reporting on what ancient cultures have known for centuries - lavender has a wide assortment of supportive healing properties. Substantial evidence points to lavender as being an important option for the treatment of anxiety and the reduction in stress. Knowledge of how scent affects the brain brings more clarity in understanding the effectiveness of essential oils to support human wellness and restore health. It is safe to assess that lavender can be regarded as more than just an attractive perfume scent. As science uncovers the benefits of lavender and further pinpoints active components of this plant, more use by conventional medicine will result. However, it must be mentioned that discovering specific active components of lavender is just one piece of the puzzle. Medical research is somewhat limited in their scope and point of reference; plant essential oils are more than their components but act synergistically, even in the minutest of quantities. Lavender is a fine example where traditional application and modern medical evaluations go hand in hand.
