The odoriferous substances (Essential oils) themselves are formed in the chloroplasts of the leaves in which 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 saved in certain areas of the plant.

Essential Oil And Plant Anatomy

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 crushed or dried, e.g.: Valeriana

Essential oils are thought of as a significant part of the plant’s metabolism: some have hormonal activity and others are a point in another procedure, e.g.: the oil found in the rind of the orange is a stage in Vitamin A synthesis.

Essential oils are available in just about any area of the plant, in differing concentrations, based on the plant itself, the time of year and day. They might be seen in the roots (e.g.: Calamus and Valerian), flowers (e.g. Lavanda, Rose,), bark (e.g. Sandalo, Legno di cedro), fruits (e.g.: Limone, Cardamomo, Arancione), berries (e.g. Ginepro), leaves (e.g. Timo, Rosmarino, Sage).

Plants which contain essences have to be picked at the proper time of day and in the appropriate season, and in particular weather conditions so that a maximum yield of these vital oils are available, and needless to say, as with all herbal or herbal plants, soil conditions, and climatic conditions will also dictate the quality of the oils obtained.

Heavy, concentrated oils are known as ABSOLUTES e.g.: Rose, Gelsomino, Oils that are solid at room temperature and which must be heated before use are known as BALSAMS, e.g.: Benzoin and Camphor.

How do essential oils work?

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

      • On the physical body, both locally and systemically, through the blood and lymphatic flow.
      • On the brain and feelings through the Sense of Smell and the Limbic System.
      • On the “Etheric Energy System” of your system through 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 through Massage, Baths, Compresses, Creams or Lotions, they are going to have an effect locally (i.e. the site at which they’re implemented ), and Systemically (i.e. through the body). The Systemic effect occurs when essential oils are absorbed through the skin to the Lymphatic Circulation, and they’re then dumped from the Lymphatic flow into the blood stream.

Once the oils are circulating in the blood, they are transported to their target organ/s, where they exert a therapeutic effect on the particular tissues. Every Essential oil has its own Target Organ, e.g. Juniper oil targets the urinary tract and kidneys particularly, with secondary effects on the Digestive, Respiratory and Reproductive Systems. Camomilla Oil targets the Nervous System via which it can then apply a wide effect on a number of other body Systems, such as the Digestive Tract for example.

When Essential oils are inhaled only, state in the kind of a steam inhalation to get a cold or as a fumigator for a backdrop “psychological” effect, the oils will be absorbed across the mucous membranes of the Respiratory Tract and lungs to the blood stream, where once more, they could travel around the body very quickly.

If Essential Oils are taken orally, their absorption through the Mucosa of the gut and to the blood is quite rapid. Hardly any essential oils are actually’digested’, which is lucky as their Therapeutic principles might well be changed if this were the case.

The reason Essential Oils behave in this way in the body is because the molecules of which they’re composed are organic molecules and quite small indeed. Following are a few of the more common Therapeutic Properties that can be obtained by using Essential Oils.

Some Therapeutic propierties of essential oils


All essential oils are to a lesser or greater extent antiseptic. This is one of the most important and valuable properties. This comprehensive description of antisptis incorporates anti viral, antifungal, anti-bacterial and overall anti-microbial activity that’s found in such oils as: Lemon, Thyme, Albero del tè, Aglio, Eucalipto, Cannella, Pino, Lavender and Sandalwood.


Oils with this property help alleviate inflammation. The signs of inflammation are typified by inflammation, pain, swelling, and partial or complete loss of function of the tissue involved. Examples of oils with this property are Chamomile, Rose, Lavender, Sandalwood, Mirra and Benzoin.


Restoration of tissue regeneration and function of cells is another outstanding property of essential oils. Oils like Pine, Basilico and Rosemary are proven to restore function to the adrenal glands, Jasmine, Cipressoe Ylang Ylang restore function of reproductive endocrine glands, rosemary and lavender stimulate cell regeneration in the epidermis.


Essential oils may also have a pronounced effect on the nervous system by producing relaxation, pain relief and relieving muscle strain. Oils with these properties include Lavender, Neroli, Rose, Geranio and Ylang Ylang.
