Colorful Description

On my friend’s farm in central Colorado grows rows of lavender, and by mid-summer its flowers fragrantly scent nearby fields. While working on the farm, I find my spirits lifted and happy despite the intense heat and my tiring muscles. It is no wonder that for much of history, lavender has been used in sachets and oils alike to bring pleasure as well s reduce stress and anxiety. Other traditional therapeutic uses include as a sleep-aid, relief from pain and headaches, an anti-inflammatory, treatment for cough and respiratory infection, and as an insect repellent as well as a perfume. Greeks, Romans and Egyptians alike have all recorded using lavender in various remedies. Today, lavender is mostly used in the same way - widely used to dress wounds, induce sleep, ease depression and reduce stress. It can also be found in ingredients of teas and culinary dishes and of course the delightful scent in perfume. Current research is investigating the antimicrobial as well as anti-cancer properties of lavender essential oil.

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.

Reducing Anxiety

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.

True lavender (L. angusifolia) is thought to have a sedative effect on the amygdala, which is considered to plays a role in processing emotion as well as governing emotional response and greatly responsible for the sensation of fear. Recent science studies looking at anxiolytic (anti-anxiety) propensities of lavender are numerous. A University of Central Lancashire, UK study (J Ethnopharmacol. 2007 May 22; 111(3): 517-25) investigated the effects of lavender odor inhalation on the behavior of gerbils (a type of rodent often used in laboratory research) and noted that exposure to lavender may have an anxiolytic effect in gerbils similar to that of the common anti-anxiety medication diazepam. A recent study published in Holistic Nursing Practice (2009 Mar-Apr; 23(2): 88-93) concluded that the use of lavender (as well as rosemary) essential oil sachets reduced stress-taking anxiety for graduate nursing students. Also in 2009, a study published in Community Dentistry and Oral Epidemiology (Nov 23) found that dental patients who were exposed to lavender scent had a reduction in their forthcoming procedure.

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).

Conclusion

The physiological pathway for molecules of lavender essential oil to reach the brain is remarkable. By following the molecular trail into the nasal cavity and its subsequent neurological reactions, one can better appreciate the recognized stress-reducing qualities found in lavender. Traditional uses of lavender are now being investigated and their diverse applications more fully understood. With science now uncovering the specialization of olfactory receptor sites for certain scent molecules, aromatherapy becomes an even more valuable remedy for maintaining wellness. We would all do well to familiarize ourselves and perhaps re-remember what our ancient brain (the limbic area) has stored for thousands, even millions of years- molecules of scent, and in this case lavender, are powerful and effective.

As consumers, we are truly embracing the natural health movement. We’ve taken a good hard look at our medical system, and realize there must be something better — and it turns out that Nature has been offering it this entire time in the myriad forms of plant medicine. Using plants and herbs for healing has been happening the whole during the whole of human civilization. Researchers have now even discovered animals in the wild eating particular plants to cure their ills. We are now seeing an explosion of interest in “aroma medicine”, the use of pure and natural essential oils as powerful healing tools. And these tools are readily available to you and your family to improve your health and wellbeing.

The body of scientific research regarding the healing actions of essential oils has grown vastly over the last 20 years. A search on Pub Med, an on-line database of the US National Library of Medicine, for “essential oil” returns 8808 results as of April 10th, 2009. The very first listing describes the anti-dementia (Alzheimer’s) effects of Lemon essential oil! The diversity of actual medical applications of essential oils is truly incredible — more diverse than just the plants themselves, as many essential oils have multiple applications. The inhalation of lemon has been shown to improve mood, improve mental accuracy and even act as an antimicrobial, perfect for general household cleaning.

Further down the same page is an abstract confirming the beauty of natural medicines: All the natural molecular constituents of Thyme essential oil have an additive antimicrobia effect — science and industry has a habit of extracting a single component, patenting it, and bringing it to market while forgetting to tell us that natural Thyme oil itself is even more effective. Other jaw-dropping notes about essential oils: Clove oil has the highest Oxidative Radical Absorbance Capacity of any natural substance ever tested — over 100,000, on a scale where blueberries score about 5,000 and Wolfberries are about 30,000. A large number of studies have confirmed the stress reducing effects of Lavender, going to far to show reduced Cortisol levels AND an increase in the body’s natural scavenging of oxidtive radicals — JUST FROM SMELLING the oil!

At this point you may be saying: that’s all well and good, but where’s the REAL medicine? You’ve heard about MRSA — the “Superbug” bacteria running rampant in the world’s hospitals, becoming a real epidemic? MRSA stands for Methicillin Resistant Staphylococcus Aureus. Methicillin is an antibiotic that is supposed to kill these bacteria, but they’ve evolved so that they’re no longer affected. Guess what: a combination of Tea Tree and Geranium essential oils plus Grapefruit Seed extract outperforms our greatest laboratory achievements in the modern production of antibiotics. Now, of course, the final test results are being withheld so that the researchers can patent the formula, but you can read through the data yourself — Google does us a giant favor that way — and see that this medicine is already available if you’re willing to blend a few oils for yourself. (It is VERY important you get the help of a knowledgeable practitioner; there are many many oils, and many therapeutic protocols. Like any medicine, it is crucial to precisely match the protocol with the condition for the greatest healing efficacy).

And for the really big one: essential oils are showing great promise in the treatment of many cancers. Frankincense and Lemongrass are just two of the oils that have been shown anti-tumorial, and Sandalwood has been show to specifically prevent skin cancers from UVB radiation exposure. Searching for “Frankincense tumor” gives a first result of: “Frankincense oil derived from Boswellia carteri induces tumor cell specific cytotoxicity”. The conclusion states: “Frankincense oil appears to distinguish cancerous from normal bladder cells and suppress cancer cell viability…” There are many more results like this, with a variety of oils and a variety of cancer cell lines. This is a very exiting time for natural medicine, as a combination of new extraction techniques, and faster turn around times in research facilities made lead to new, life saving protocols in the very near future (and it’s important that we as members of the world community keep voicing our opinions, and making these changes in our available medical treatments — it’s not only good for us, it’s good for the world as well, as the production of natural medicines takes SO much less energy than their pharmaceutical “equivalents”).

It’s important to note that essential oils don’t just effect serious medical conditions — they have a place in our everyday lives, too. Tea Tree essential oil is a wonderful, effective antibiotic, especially useful when combined with soothing Lavender for childhood cuts and scrapes (if you’re tough, just use the Tea Tree to prevent infections). Essential oils have been shown to reduce bacteria in the mouth which reduce tooth decay. Helichrysum essential oil is one of the most profound pain relievers and inflammation-reducers for muscular injuries, and makes small kitchen burns heal almost instantly (just a drop on that little hot spot and you’ll be quickly convinced!). Sea Buckthorn heals wounds and reduces wrinkles. Chamomile or Mandarin have been used for years in Europe to soothe the traumas of childhood, and lend a hand to parental sanity. The scent of many pure essential oils just makes folks happier (and it’s important to note this same results do not occur with “fragrances”, a term for man-made smells — they do not have the same make-up as natural plant aromatics do — and in fact, many people are allergic to them).

Sure, this can sound a little overwhelming…where, really, to start when you’re new to it all? Well, that’s the trick: just get started. Anyone in your family not sleeping well? Rub a drop of lavender on each foot at bedtime for a few nights and see what happens. Someone with athlete’s foot or other similar rashes? Mix 30 drops of Tea Tree and 30 drops of Palmarosa into a fluid ounce of Jojoba oil and massage into the area a couple times a day. Just get a simple diffuser, some Black Spruce essential oil and make your house smell like the middle of the forest. Dab a drop of Rose, Amber, Jasmine or Sandalwood oil to your wrist, rub them together and smell like heaven. It’s that easy. And these simple ideas get you ready for when you might need to tap into the serious medicine available here. Essential oils won’t be foreign anymore, and you’ll start to trust their real medicinal value. Also, there are tons of great books, and very qualified teachers. Open your eyes and heart to the world of Aroma Medicine, and you’ll be sure to find your way.

So what is aromatherapy and what exactly are essential oils? Well, essential oils are the final product of a process of extraction from plants. This process distills and concentrates the essences of various plants to make them useful for aromatherapy. There are many ways this extraction process can be done. Usually, it is completed through a process called distillation.

So what can essential oils be used for. Many things! It’s uses can vary from basic aromatherapy to perfumes, flavoring of food and anti-aging,etc. For it’s use in aromatherapy, the essential oils are known to contain healing properties which also can help to rejuvenate the mind and body. It can help to relive stress and sooth pain.

In the case of being used in perfumes, the essential oils are mixed and blended together with water and alcohol. The flower fragrances are what gives it it’s distinctive smell. By changing the percentage mixture of essential oils, water and alcohol, the strength of the perfume scent changes accordingly. As a frame of reference, a perfume that has a strong scent will usually have only about twenty percent essential oils, seventy five percent alcohol and the remaining five percent consisting of water.

For skin-care products, essential oils are used widely in creams, shampoos and moisturizers. Not only that, massagers in spas also used essential oils to apply on their client’s bodies before an actual massage.

For uses in food products, essential oils are used to add flavor to the foods. This is most used in foods that are kept in packages for long stretches of time. Besides flavoring, essential oils also supposedly aids in food digestion. They can help in relieving stomachaches and poisoning of food.

Lastly, essential oils can also be used as mosquito repellents. Surprised? Well eucalyptus oil does just that. So instead of burning those coils which can be potentially filled with not very healthy smoke, why not just heat up some eucalyptus oil and let it do the trick? You’ll be pleasantly surprised that it does the job of driving away mosquitoes just as well.

So there you have it, several benefits and uses of essential oils that can be utilized. And you thought it was only limited for aromatherapy uses?
