Sandalwood Oil’s Anti-Cancer, Sleep Enhancing, And Mood-Supportive Effects

Sandalwood is one of the most treasured aromatics by aromatherapy practitioners, and perhaps one of the most treasured by human civilization as well. Recorded use of the wood and its products date back over four millennium, more than any other aromatic plant. Yet while most practitioners make use of the oil for its unequaled scent, few are aware of some of its important science-proven medicinal effects.

The exotic oil comes from the heartwood of trees native to certain tropical regions of the world. Curiously, the sandalwood tree is only found growing on, or intertwined with, other trees; it’s considered, in fact, a parasite. Further, the trees are quite slow growing, and demand a certain amount of age before being mature enough to distill a significant volume of high-quality oil. This makes for a unique challenge in growing the wood and distilling the precious essential oil.

The very finest oil, certainly aromatically — and some people believe therapeutically as well — is distilled from the Santalum album species native to India. The essential oil has become so highly valued that over-harvesting of the trees has made a significant impact in deforestation in certain regions. So much so that the government of India made it a law that they now own all the sandalwood trees in the country! This, of course, is meant to prevent poaching of the trees, as clearly the offense is rather serious stealing the valuable resource from the government. Thankfully, there are plantations of this same species of tree underway, and other sources of very fine sandalwood oils that are now close in rivaling the quality of the Indian material.

It is clear that for the reasons of rarity alone, the essential oil is something to be cherished. However, the oil has some very impressive and important medicinal qualities that make it even more valuable. One application is a direct derivation of the use of the wood’s paste for skin care: The essential oil has been shown to prevent the occurrence of skin cancer if applied before exposure to UVB light as well as chemo-toxins.

Researchers have gone on to elucidate the ways the oil prevents cancers from forming on a microscopic level, noting the effect is a result of the primary natural chemical constituents of sandalwood essential oil. The important point is that this constituent is found in the essential oil from the three primary commercial sources: India, Australia and certain islands in the South Pacific. There are even sources where trees have been specifically selected for “high santalol content” which you can find from some aromatherapy companies. Including sandalwood essential oil in your skin care formulas is an excellent way to potentially make use of this wonderful benefit.

The aroma is highly regarded for its calming, centering qualities, without being sedating. Researchers in Vienna, Austria published research indicating study participants were positively affected in the areas of alertness, attentiveness, calmness, mood, relaxation and vigor. This correlates to its long-time use as the first choice aromatic in aiding meditation. It is reputed to quiet mental chatter, again while bringing the awareness to a singular focus.

While the aroma is stimulating in certain ways, calming in others, and never considered “sedating”, it has been shown in research to significantly improve sleep for those who may frequently have trouble falling or staying asleep. Sleep-disturbed subjects spent much less time awake, and much more time in dream-sleep when exposed to the oil’s vapor. However, researchers also concluded that the effect was not from the actual scent of the oil, but from action of the oil once in the bloodstream. If using sandalwood for sleep, it’s not necessary to smell it — the feet tend to be an area of the body very receptive to the actions of essential oils, and a gentle foot massage with a dilute sandalwood oil formula may help those who are having sleep difficulties.

These are only a few of the important health benefits available from sandalwood essential oil. It has a host of other wonderful skin-care properties, being used for nearly every skin care condition imaginable. It’s also an excellent fixative for natural perfumery, functioning as the base note in many fine colognes and perfumes. Because the chemical profile of the oil from the three primary sources on the globe are relatively close, you can generally use any of these for the therapeutic effects described here. For perfumery and other aromatic applications, try sampling oils from Australia and the South Pacific island of Vanuatu, in addition to an Indian oil if you can acquire it. This way you can become familiar with the range of aromas — investing in a quantity of the oil once you find your favorite is a great idea. The aroma gets even better as the oil ages, so both the price and your appreciation for your stock will increase over time.

Tea Tree, Lemon and More: Using the Antiseptic Action of Essential Oils

The anti-bacterial action of essential oils may be their most studied effect, in-part because these are simple experiments to perform. Place a piece of filter paper saturated with an essential oil in the center of a petri dish and watch the growth, or lack of, bacteria around the paper. The larger the area where bacteria do not grow, the stronger the action of that particular essential oil inhibiting that particular strain of microbe. This test, known as an Aromatogram, was popularized by French scientist Paul Belaiche. Through extensive research, large tables of data now allow aromatherapists to quickly find the most efficacious oils once the infecting species of bacteria is known. But you don’t have to be a scientist to make use of this information – there are many simple, effective means for using essential remedies for yourself and your family and children as part of a holistic natural health program for your household.

Essential oils derive their antimicrobial effect from their unique chemical makeup. Each single, pure essential oil consists of several, sometimes hundreds of distinct natural chemicals. Many of these have antimicrobial activity, and show synergistic effects; blends of the chemicals – as found naturally in the oils – can be more potent than any individual chemical alone. Many studies have shown that Carvacrol, the primary molecule found in oil of Oregano, has exceptionally strong antimicrobial activity. Further studies have noted the combination of Carvacrol and Thymol (a minor constituent of the same oil) to be more potent than either of them alone. So the next time you might reach for Neosporin or rubbin alcohol, you might consider that the remedies nature has made will likely work better.

There’s evidence for an incredible spectrum of antimicrobial action from essential oils, yet it is important to select the right oils in the right amounts. Topical application of Oregano and Thyme may be the best solution for a case of stubborn nail fungus, yet these oils are far too intense for use on soft tissue of any kind except in the most dilute blends. Often a combination of a potent antiseptic with a known soothing oil can improve the overall effectiveness. Here we will briefly profile these highly-regarded oils, and look at some formulas and methods of application: Tea Tree, Lavender, Oregano, Geranium, and Lemon.

Tea Tree may be the hands-down most popular antiseptic essential oil. Tea Tree is a must for every natural first aid kit for the home. One of the safest and most effective ways of controlling minor infections is the immediate intervention action of Tea Tree. Tea tree’s tolerability allows it to be used for longer periods of time without the slightest irritation. A drop on a Band-Aid can keep the reddening indication of infection from children’s cuts and scrapes, and when combined with Lavender, makes a soothing rendition of popular over-the-counter antibacterials. Tea tree can also be used directly on minor wounds for those with less sensitive skin, and is highly useful as an acne treatment – some individuals can use it ‘neat’, while others should dilute it in Hazelnut oil (a ‘non-oily’ base oil that will not exacerbate an over-oily skin condition).

Lavender is the most versatile essential oils in use today, and in fact began the modern medical aromatherapy revolution through its quick healing of burns by a French cosmetics chemist. The cooling aroma disperses heat and inflammation and brings relief from pain, spasms, and general unrest. With its calming and balancing properties, the oil is exceptionally supportive of relaxation and rest. Lavender imparts this action in healing wounds as well; for healing unbroken skin such as burns, apply Lavender ‘neat’ to the wound several times a day; insect bites also get a ‘neat’ treatment. For cuts and scrapes, keep a equal mix of Lavender and Tea Tree on hand for the best all-purpose antiseptic, anti-inflammatory and pain relieving solution. Moms will really appreciate the synergy of the antibacterial nature of Tea Tree and the soothing effects of Lavender.

While the Tea Tree and Lavender blend gives us a formula for regular use, Oregano is the all-time heavy-hitter of essential oils for antimicrobial action. Oregano is serious medicine; it has been the subject of many successful scientific evaluations. Interest in the oil’s efficacy growing in amongst the world’s medical practitioners as infectious microbes become more and more resistant to synthetic antibiotics. Pure oil of Oregano is exceptionally strong – too strong for topical application except in the most stubborn cases, and then only with careful attention. Oregano holds the most promise as a systemic antimicrobial; Oregano oil can be found in enteric-coated (for targeting parasites and bacteria in the intestines) and regular capsules for support of the immune system during illness. Consult a qualified medical practitioner for dosage recommendations.

With a softer aroma and gentle effect on skin, Geranium is versatile choice for frequent use. Known as the ‘flower of constancy’, Geranium helps to lift the spirits and bring joy and happiness to one’s daily activity. Harmonizing and balancing, Geranium essential oil has the quality of equalizing hormonal and emotional extremes. These properties extends to the skin, where it creates balance between oily and dry states; Geranium helps to cleanse the skin while restoring balance, tone, and suppleness (try including in your skin care formulas at 0.5% to 3%). A non-drying, antiseptic, anti-inflammatory, astringent, and general tonic, Geranium is traditionally indicated as a remedy for acne, dermatitis, eczema, and weeping wounds. Geranium essential oil is one of the few that has been used successfully against the MRSA bacteria in laboratory studies. The ‘asperum’ sub-species (also known as Egyptian Geranium) is generally considered the most potent Geranium for its antimicrobial action, with a wonderful sweet and herbaceous aroma.

Lemon essential oil is a powerful antiseptic and bactericide that performs many tasks around the house, as well as for your health. Lemon has a tonic action on the lymphatic system and a stimulating action on the digestive system, additionally providing relief from insect bites and tension headaches. Use this pleasant antimicrobial blend with confidence to clean counter tops, windows, and door handles: 2 drops each of Lemon, Pine, and Eucalyptus Radiata essential oils in 4 ounces of distilled or spring water (distilled water dries without leaving haze from mineral deposits). Keep a spray bottle of this solution handy for your day-to-day cleaning.

There are many, many choices for antibacterial and antiseptic essential oils – these are a few of the most commonly used oils with a broad range of applications. Many oils, particularly when properly blended, can have greater specificity for your individual needs. There are many excellent books available by reputable authors – ‘Advanced Aromatherapy’ and ‘Medical Aromatherapy’ by Dr. Kurt Schnaubelt, and any of the books by Valerie Worwood are worth investigating to further your knowledge in the practical application of essential oils. These books cover the safe use of essential oils in general, and specific conditions you’ll want to be aware of when delving deeper into aromatherapy. In selecting essential oils over synthetic preparations, you’ll find great satisfaction making the natural choice for yourself and your family.
