What is aromatherapy and is it safe for me?

Aromatherapy has many benefits to the mind and the body, but what is aromatherapy, what are essential oils and how do you know if they are safe for you?

I am often asked whether essential oils are safe to use during pregnancy or for someone suffering from a medical condition. This blog looks at which essential oils you should be avoiding (and why) if you do suffer from any medical conditions or fall into one of the vulnerable categories.

What is aromatherapy?

Aromatherapy is the modern term used to describe the practice of using natural essential oils. Essential oils are pure and concentrated extracts distilled from the flowers, bark, stems, leaves, resin, fruits and roots of plants. They ared are used to heal and to enhance a person’s wellbeing.

The word essential demonstrates the plants natural essence, its being; whilst the oil indicates that the liquid is insoluble in water.Aromatherapy is the skilled and controlled use of essential oils for physical and emptional well being

‘Aroma’ ‘therapy’ is a two-part process, utilising both the aroma and the chemical makeup of the essential oil to provide it with its ‘therapy’. The aroma can give comfort to the emotions whilst the chemistry makeup of the essential oil can affect the body.

An essential oil contains many different chemical structures, and it is this that gives the essential oil its unique properties in both its aroma and its psychological and physiological effect on the body.

When essential oils are applied to the skin we receive their wonderful aroma. Essential oils are also unique in their ability to penetrate the skin and enter the blood stream, which is why they are used in skin care products to treat skin conditions.

Essential oils can also be used to help with our wellbeing. Methods include vaporisation, aromatic bathing, massage, cosmetic creams and steam inhalation.

Is aromatherapy safe for everyone?

The reason that aromatherapy can be so powerful lies within the chemistry of the essential oil, for this reason we have to be aware of the contraindications that certain essential oils have.

However, by using aromatherapy safely we can harness all the wonderful benefits that essential oils possess. We can let their therapeutic properties benefit both our mind and body enabling us to support ourselves and our health.

The following lists of essential oils are not exhaustive, but cover all the oils that I will refer to in any of my posts or use in my products.

Remember, never apply essential oils direct to the skin, always dilute them with a carrier oil.

When using essential oils on or around children we need to take extra care. If ingested seek medical attention immediately.

There are differing opinions on the age of the child and whether or not to use essential oils. My approach is to use a lower dosage (1% of essential oil in 30ml carrier oil) only on children who are over 6 years of age. Essential oils should not be used at all on children under 6 years of age.
