Aromatherapy – Part I: Essential Oils

Aromatherapy – Part I: Essential Oils

a) WHERE DO ESSENTIAL OILS COME FROM ? - Essential Oils – Part 1

The odoriferous substances (Essential oils) themselves are formed in the chloroplasts of the leaves where they combine with glucose to form glucides and are then circulated around the plant in this form. At certain times of the day or year they are stored in particular parts of the plant.

In some plants, the essential oils are produced by the secretory tissues, and in others they are combined with glycosides, and are therefore not detectable until the plant is dried or crushed, e.g.: Valerian

Essential oils are considered to be an important part of the plant's metabolism: some have hormonal activity and others are a stage in some other process, e.g.: the oil found in the rind of the orange is a stage in Vitamin A synthesis.

Essential oils can be found in almost any part of the plant, in differing concentrations, depending on the plant itself, the time of day and year. They may be found in the roots (e.g.: Calamus and Valerian), flowers (e.g. Lavender, Rose,), bark (e.g. Sandalwood, Cedarwood), fruits (e.g.: Lemon, Cardamom, Orange), berries (e.g. Juniper), leaves (e.g. Thyme, Rosemary, Sage).

Plants which contain essences must be picked at the correct time of day and in the correct season, and in particular weather conditions in order that a maximum yield of the essential oils can be obtained, and of course, as with all medicinal or nutritional plants, soil conditions, and climatic conditions will also dictate the quality of the oils obtained.

Heavy, concentrated oils are called ABSOLUTES e.g.: Rose, Jasmine, Oils which are solid at room temperature and which must be warmed before use are called BALSAMS, e.g.: Benzoin and Camphor.

HOW DO ESSENTIAL OILS WORK?

Essential oils are known to have an effect on us in three different, but overlapping, ways.

a)On the physical body, both locally and systemically, via the lymphatic and blood circulation.

b)On the mind and emotions via the Sense of Smell and the Limbic System.

c)On the “Etheric Energy System” of the body via the energy vibration of the individual oils themselves.

The Way Essential Oils Effect the Physical Body

When Essential oils are applied to the surface of the body, either via Massage, Baths, Compresses, Creams or Lotions, they will have an effect locally (i.e. the site at which they are applied), and Systemically (i.e. throughout the body). The Systemic effect occurs when essential oils are absorbed through the skin into the Lymphatic Circulation, and they are then dumped from the Lymphatic circulation into the blood stream.

Once the oils are circulating in the blood, they are carried to their TARGET ORGAN/S, where they exert a therapeutic effect on the specific tissues. Every Essential oil has its own Target Organ, e.g. Juniper oil targets the urinary tract and kidneys in particular, with secondary effects on the Digestive, Respiratory and Reproductive Systems. Chamomile Oil targets the Nervous System via which it can then exert a broad effect on many other body Systems, like the Digestive Tract for example.

Even when Essential oils are inhaled only, say in the form of a steam inhalation for a cold or as a fumigator for a background “psychological” effect, the oils will be absorbed across the mucous membranes of the Respiratory Tract and lungs into the blood - aroma therapy for anxiety
