As we’ve seen, essential oils have been used by humans for over a thousand years. Nevertheless, we have only seen some of their potential so far. Knowledge of essential oils has previously been based solely on what people say. But lately, there has been an explosion of scientific research on essential oils. This has led to a number of publications and a lot of documentation. In the last ten years, more studies on essential oils have been published than in the previous 500 years combined.
Qu'est-ce que l'aromathérapie exactement ?
Aromatherapy is the use of essential oils from plants (flowers, leaves, bark, resin etc.) as a complementary health treatment. The essential oils are often dispersed into the air by means of a diffuser. They can then be inhaled. Alternatively, they are applied in a diluted form to the skin from where they are absorbed and inhaled. Many essential oils are used in aromatherapy for their different properties. We’ve already seen some of the more popular ones. Other lesser-known ones include plai, neroli and cardamom.
Aromatherapy is used as an aid against stress, depression, burnout, and insomnia. It is sometimes included in massage therapy, for example in the treatment of painful joints and muscle tension, and to relieve the symptoms in people with cancer.
A study that researched the use of the essential oils of lemon and lavender for people under stress documented that lemon had a positive effect on mood. The NCCIH conducted the study, and they point out that aromatherapy is not intended to replace medical expertise and advice from healthcare professionals but can be used to complement it.
Quelle est l'explication scientifique derrière les huiles essentielles ?
When inhaled, "the absorption of essential oils in the nose is as fast as an intravenous injection," says Gerhard Buchbauer, professor of pharmaceutical chemistry at the University of Vienna in Austria. He has researched and written about the chemical compounds used in aromatherapy. “The oils contain both simple and complex chemicals,” he continued.
Each bottle of essential oil contains a unique chemical blend. These compounds evaporate quickly. Their chemical structures are mainly made up of carbon atoms. The chemical particles in the essential oil can provide therapeutic effects through their interaction with our body.

A study at IFTM University in India researched the sun protection factor (SPF) and the antioxidant potential of geranium essential oil. It was observed that geranium oil has the potential to reduce or prevent oxidative stress and can be used in skincare products to reduce skin ageing via its antioxidant properties. The results also showed that geranium essential oil can be used in sunscreen to protect the skin from sunburn.
Another study from Japan researched menopause. Many women experience health-related symptoms during menopause due to a drop in oestrogen levels. It has long been known that some essential oils have the ability to relieve menopausal symptoms. Based on this, it is possible that some essential oils may normalize oestrogen levels in women. The Japanese study results showed an increase in oestrogen concentration in saliva caused by exposure to geranium. Together with previous studies, this research supports the idea that inhaling certain essential oils can affect the saliva concentration of oestrogen.
