Do Essential Oils Really Work?


I love using essential oils in my home. I use them in cleaning products, beauty products and in my diffuser to boost mood. But can just a few drops of plant-derived oils really kill germs, fight acne and reduce stress? It seems a little pseudo-sciencey, too good to be true.

So, I decided to do my research. Am I throwing good money after bad when I use my essential oils? Is it all just a big waste of time and effort?

The scientific answer is not clearcut.

Some studies have shown that certain essential oils have the powerful properties that aromatherapists claim. Others have been inconclusive, still more studies have shown that certain oils definitely don't have magic healing powers.

I am neither a scientist nor an aromatherapy expert, so muddling through the articles on both sides of the argument quickly became overwhelming.

The conclusion that I came to was that - as most studies state - more research needs to be done. What we can say for sure, is that essential oils are not miracle workers. They will not fix your depression, cure your cancer or give you the perfect night's sleep in one go. But many of them will help with certain, specific issues.

How does diffusing essential oils work?

Smell is one of our major senses, yet we often overlook the importance it has in our lives. Our senses all feed information to our mitochondria which is responsible for instructing our bodies on how to react to the world around us.

When we inhale essential oils they stimulate the limbic system (a major centre of our brains which responsible for our emotions, behaviour, memory formation and more). Some scientists have suggested (although, again always with the caveat that more research is needed) that certain essential oils can therefore promote certain reactions.

It may be that essential oils only provide a placebo effect or that the ritual around their use has more impact in calming or mood boosting than the oils themselves.
