A synergy is a blend, an association of several essential oils whose different modes of action reinforce each other. Their combined action is more powerful than the addition of their individual actions.

What is the point of blending?

First of all, it is interesting to approach a problem whether it is emotional or physical from diverse angles.

For example, in a sprain, the objective would be to decrease the pain and the inflammation. Different essential oils can help with these discomforts. Some will be analgesic, others will be anti-inflammatory or anti hematoma. So, to alleviate the sprain discomfort, I’ll mix essential oils with different therapeutic properties: for example Wintergreen, Peppermint, Eucalyptus, Helichrysum, .... to combine their forces to optimize the result.

For issues related to stress, it is important to understand the underlying reasons, it could be overwhelming, lack of sleep, or lack of confidence for instance. In case of lack of confidence, I’ll use essential oils helping with stress as lavender, sweet orange, and essential oils for confidence as sweet basil. All depending on the persons’ expressed emotional state.

“The expression of the whole has greater effects than the sum of all its parts. We create this synergy by mixing. ”

Secondly, essential oils are very potent extracts; a small amount goes a long way. Hence the importance of dilution in a carrier oil (= jojoba vegetable oil, fractionated coconut, evening primrose, avocado, etc.) Besides, dilution allows us to preserve our planet’s precious resources.

Compose your synergies with confidence and method with this process:

  1. Blending according to therapeutic properties

  2. Blending by plant parts

  3. Blending by type of aroma

  4. Dilution and safety guidelines

Blending by Therapeutic Properties

See studies and relevant books as “Essential oil safety” by Tisserand and Young or “Modern Essential Manual” by AromaTools.

Blending by Plant Parts

When we consider the part of the plant that the essential oil is extracted from - and use this information in parallel with the human body, everything becomes clearer and more obvious.

Considering the plant part is a great way to approach the emotional aspects of a blend.

Let me explain, imagine a synergy based on oils extracted from flowers. What comes to my mind? I immediately feel the connection of the heart, the beauty of the flowers, the colors, and the range of floral and sweet aromas. This aroma offers comfort and sweetness. When someone is feeling grief or loneliness, I would go for flower extracts. Now imagine a blend made only from root oils. How is this feeling different? The roots of plants are deep in the earth, anchoring the plant to the ground. When I smell the root oils, I feel anchored, installed, connected. When someone is feeling baseless, anxious, or disconnected, I could make a blend of root oils.

I often mix two or three plant parts to provide support on several levels.

  • Seeds are the reproductive system of the plant, it contains the beginning of life and contains the full potential of the plant. It supports transitions and periods of renewals, rebirth.

  • Roots anchor the plant in the soil and nourish the plant. It helps to nourish the soul and stabilize us in challenging periods. It brings balance and grounding.

  • The wood brings the nutrients from the roots to the top, it’s the spine of the tree. It centers the energy, it calms down.

  • The resin helps plants to heal. It soothes trauma and supports emotional healing. Most of the time it helps with scars.

  • Leaves, twigs, herbs are the respiratory system of plants. It helps us to breathe as well on an emotional (stress, overwhelm, load on your chest) and physical (congestion, cold) level.

Blending according to Aromas

The aromas are classified into three major categories:

  • Top notes

  • Middle notes

  • Base notes

The top note is perceived first but quickly fades. This category is represented by essences of zests or plants with citrus scents and pines. These oils add vibrancy to a blend. The top notes stimulate and clear your mind, uplifting your energy.

Essential oils with a "top note": lemon, mandarin, orange, grapefruit, bergamot, scots pine, eucalyptus globulus.

The middle note occurs second and gives balance with some sharp edges to the fragrance.

Middle notes ensure physical and energy balance. Essential oils from flowers and herbs mostly represent this category.

Essential oils with a "heart note": chamomile, lavender, peppermint, geranium, rose, petitgrain, helichrysum, wintergreen

The base note arrives last. It corresponds to the structure of the perfume and guarantees its stability. Base notes are used to relieve stress, anxiety, and insomnia. They calm and soothe. They generally correspond to resins, woods, and roots. The base notes are soothing and harmonious for the mind and the body. Essential oils with a "base note": frankincense, patchouli, cloves, cinnamon, vetiver, sandalwood, cedarwood.

To create an olfactory harmony, it is necessary to keep a balance between these three notes.

The key proportion according to perfumery

  • Base note: 1 drop

  • Middle note: 2 drops

  • Top note: 7 drops

The magic of harmony is created by respecting these proportions. This is true in terms of perfumery. When the goal is more therapeutic, other proportions may apply. This is a guideline to help you.

If you want a blend that brings energy, that is invigorating and vibrant, you will insist on top notes oils such as citruses for example. On the contrary, if you want a more calming mix for sleep and relaxation, add base notes for grounding and deep calm.
