Essential oils are dynamic in many ways.

They are highly sensitive organic fluids which, if not stored under proper conditions, are detrimental to their properties.

They lose their healing potential, or so-called “invasive force,” and in this sense, they are taken as dynamic fluids, applied on the body, they act too quickly, they easily pass through the skin and can penetrate through the walls of the blood vessels and essential tissues. Essential oils are dynamic because they enter the body, exert their action and leave it in a mild and uninhibited way.
In fact, one reason for diluting them into vegetable oils is the need for some delay in their action. Although they do not stay in the body for more than three or four hours, they unlock a healing process that may last for days or even weeks afterward.

Essential oils are dynamic because they act on several levels simultaneously, influencing organs, functions, tissues, fluids, cells and fine energy.

Their dynamic nature also consists in the fact that, despite the strong dilution, they are efficient. A study of the effect of lemon oil in stimulating the release of mucus from the lungs proves that doses equivalent to both 68 drops and 1/30 of a drop inhaled from a normal human are equally effective. Doses between the two extremes are far less efficient.
Another proof of the dynamics of essential oils is the fact that they are synergistic. Synergy means joint action, in harmony. Typically, essential oils are more useful when added to other essential oils. Mixing two to five oils is a rule in all branches of aromatherapy. For unknown reasons, the use of more than five or six, seems to have a reduced effect. Instead of increased potential, there is reduced performance. Combining oils is not in itself sufficient to provide a more active effect – much depends on what oils are mixed and for what purpose. An overwhelming example of synergy can be found in the study of the antibacterial action of 35 essential oils carried out in 1958. First, the authors tested each oil against five pathogenic bacteria and then tested the same oils in combinations of two and then – three. None of the double blends showed an increased effect, whereas 20% of the triple scored a better result. The most effective combination against specific bacteria is that of eucalyptus, cinnamon and juniper, which is 29% stronger than the same oils applied separately.
The synergy effect is also noted by Valne while discussing the issue of electrical resistance. He exemplifies four essential oils: cloves, thyme, lavender and peppermint. The electrical resistance of this mix, which is expected to amount to 3275, is actually 17,000, that is, five times more. The resistance of the mixture is much higher than the composite essences. Aromatherapy combinations do not always achieve synergy, but when it is available, the result is significantly higher than the sum of the individual ingredients.
It should be emphasized that French aromatherapy therapists based on aromatherapy use mainly aromatic oil mixtures and rarely apply the most effective. In holistic aromatherapy, combinations have been known since Maury’s introduction of the concept of “individual prescription.” They have other advantages: Perfume is an example of a kind of synergy in action, as the desire is to “represent a mixture in which the combination as a whole smells better than any ingredient taken individually. ” In the same line of thought, it should be emphasized that simple combinations of essential oils and as a scent are, in general, more attractive than single oils. Without stopping on the aesthetic side of the issue, this also leads to a higher degree of perception by patients, which may prove to be essential in the treatment of mental and stress-induced disorders. By using blends of oils it is possible to obtain a cure that has a finer and more sensitive attitude to individual needs. With a selection made of no more than 25 essential oils, over 15,000 combinations, each of two, three or four essences, are possible.
Synergism also has other dimensions. The properties of essential oils can be influenced in a different direction depending on what other ingredients they mix with. A suitable example in this regard is bergamot oil. Combined with jasmine, it acquires an erogenous property; orange blossom has a soothing effect; in combination with lavender or tea bush, its antiseptic effect is predominant, and when it is mixed with rosemary, it has mostly an invigorating and stimulating effect. Bergamot essential oil is one of the most easily adaptable.
