Properties of essential Oils
While each essential oil has its own unique properties, many also share some common therapeutic actions. All plant essences are antiseptic to a greater or lesser degree; good examples being eucalyptus, tea tree and thyme. Some oils are endowed with antiviral properties as well; garlic and tea tree being two of the most powerful.
For obvious reasons, garlic essence is not usually employed in aromatherapy massage (though it has been known!) but instead, is taken as a medicine in the form of garlic capsules. Many essences, notably rosemary and juniper, are also antirheumatic. When rubbed into the skin, they stimulate blood and lymphatic circulation and increase oxygen to the painful areas, which in turn aids the elimination of tissue wastes (uric and lactic acids, for example) which contribute to the pain of arthritic and rheumatic complaints.
Another interesting property of many essential oils (and also herbal remedies) is their adaptogenic or 'normalizing' ability. Researchers in eastern Europe have found that garlic has the ability to raise abnormally low blood pressure, and to lower blood pressure that is too high. Essential oil of hyssop is cited as having the same action. Studies have shown that it causes blood pressure to go up, then down, then back to normal, as if testing out the required pressure! A phenomenon which is totally alien to a synthetic or chemical drug.
Valnet and other doctors in the field of medical aromatherapy have also discovered that blends of certain essences are not only more powerful than when used singly, but that the mysterious factor of synergy is at work - the effect of the whole becoming greater than the sum of its equal parts.
This is particularly noticeable with the anti-bacterial action of essential oils. A blend of clove, thyme, lavender and peppermint, for example, is far more powerful than the chemist might expect of the blend, taking into account the combined chemical constituents of the oils. Curiously, mixing more than five essences is counter-productive. The anti-bacterial action is weakened. But even as loners, certain plant essences are remarkable aggressors against microbial germs. According to Valnet, essential oil of lemon neutralizes typhoid, diphtheria and pneumonia bacteria in less than three hours. To ascertain the most efficacious oils for a particular person, French aromatherapy doctors usually employ the aromatogram. This involves taking a swab from an infected area of the patient, culturing it in the laboratory and then testing as many as fifteen different essences to find out which blend of oils would be the most effective for that particular person's infection. The most potent oils are then encapsulated and administered orally. It may come as a surprise to learn that a different patient suffering from the same named bacterial invasion will need a different blend of oils in order to combat the infection.
