The science of volatile plant oils

It's an amazing world, this world of plant oils. The oil that comes from a plant are known as volatile substances because by definition they dissipate into the air sending their molecules airborne. And those molecules can can be strong:  oils are up 70 times more potent than the plants they come from and whether it's the roots, peel, fruit, flowers or bark, each oil has its own fascinating therapeutic and powerful properties. There are two ways the ingredients of DESAVERY products can be absorbed by your body. The first way is through topical application  - the skin absorbs the plant oils as you massage them into your face. The second way - and this is how our ingredients can affect your mood and mind - is through the inhalation of the ingredients. 

Our noses are full of olfactory receptors which are directly connected to the limbic system in the brain (the part that controls emotion, hormones and cognition). The airborne aroma molecules literally hit the limbic system and can start making changes in your brain chemistry immediately. Of course the idea that smell can illicit certain emotions and feelings is not new, after all incense has been used in churches and temples for thousands of years, and we all know that lavender can make you feel more relaxed. However, what is new are the many studies that have measured the impact of specific plant oils on everything from hormone levels like cortisol, changes in neurotransmitters such as serotonin and the ability to improve focus and other cognitive functions simply through the inhalation of certain plant aromas. Part of the reason there has been so much research in this area is that scientists are exploring the idea that plant oils might hold valuable properties to help with some of the current healthcare crises: the overuse of antibiotics, addiction to painkillers and the reliance of other prescription drugs. It's this new body of science that is behind DESAVERY.

here are some of the oils that feature in our products

A grass native to India, vetiver is an intriguing plant. It's a wonderful species that can stop erosion and it's roots are effective in detoxifying water! In a landmark study on essential oils and ADHD vetiver oil was shown to be the most effective of all the essential oils examined. This study conducted in 2001 was with a small group although the findings were compelling.  In 2016 a more extensive study confirmed these findings; inhalation of vetiver improves alertness and task performance.




I had to throw this one in - not only does it smell wonderful, wait for it, inhaling rosemary is shown to improve several cognitive functions. Here's an excerpt from the study: "Here we show for the first time that performance on cognitive tasks is significantly related to concentration of absorbed 1,8-cineole following exposure to rosemary aroma, with improved performance at higher concentrations. Furthermore, these effects were found for speed and accuracy outcomes, indicating that the relationship is not describing a speed–accuracy trade off." Basically you can do tasks faster and with greater accuracy. I'll take it!



CLary sage

There are quite a few studies around clary sage. However the most compelling is one out of Seoul in 2014. Fifty women participated in a study at the Sookmyung Women's University. After inhaling clary sage essential oil the subjects' cortisol levels dropped immediately. There was also a measured increase in the receptors that produce serotonin (this is a natural mood stabiliser). On the Beck Depression Inventory, those that inhaled the clary sage reported feeling happier overall and that was the case for those who identified themselves susceptible to depression and those who didn't. This is one of several studies on the uplifting and powerful effects of clary sage.

Bergamot is one of the essential oils that I love. Its citrussy/floral aroma is gorgeous but it has a unique dual effect in its impact on the brain (and juniper shares this quality) because it makes you feel more alert and at the same time more calm. There are several studies that measure the very positive effecst of bergamot on mood states, the parasympathetic nervous system and the hypothalamus system.
