12 Must Have Essential Oils and How to Use Them

Essential oils are the primary colours of smell. They are powerful, easily recognisable and mix to make up many of the other smells around us. The good ones anyway.

In the quest for health and wellness, smells are often overlooked. Essential oils have amazing aromas and can be incredibly powerful tools to improve mood, enhance relaxation, build energy and increase focus.

They have the power to entrance you and to alter your mood, but their benefits are probably greater than you thought. By inhaling an essential oil or mixing it with a carrier oil and applying it to your skin, you can unlock further benefits for your body and mind.


What are essential oils?

An essential oil is an on oil made from concentrated plant extract and retains the smell of the plant. The smell, and some of the benefits, come from molecules called terpenes that are found in the oils.

Terpenes are natural chemicals created by plants that are often used in cosmetics. If you look in your bathroom you are guaranteed to find one or two products that contain terpenes. Check the ingredients and look out for names like linalool, limonene, pinene or myrcene.

True essential oils are distilled or cold pressed and are pure concentrates. When you smell them in this form the aroma is intense and over powering making them best for use when diluted or diffused.



How to use essential oils

Essential oils shouldn’t be eaten but can be inhaled or applied to the skin. Once you’ve chosen your oil you have a number of choices.

Cold diffusion – Add a drop to your pillow or clothes to inhale it. This is great if you are suffering from headaches or colds.

Add some drops to cotton wool and leave in a room to diffuse the aroma into the air. Reed diffusers can also be used.

Hot diffusion – Oils can be dropped on specially designed burners. This is great if you want to fill a room with an strong smell very quickly but in the long run it isn’t ideal. It uses a lot of oil in a short time and the smell can be too intense.

Electric diffusers –  These are mains or battery powered diffusers that mix a small amount of oil with water and diffuse it into a room as vapour. This is the most effective and cost effective method that I have found. It uses a small amount of oil but gives you a big effect that lasts for hours.

Baths – Adding a few drops to a bath is a great way to relax. You can add the drops directly and disturb the water to mix them, or add other products like epsom salts to properly disperse the oil.

Topically – Adding essential oil to cosmetics or carrier oils  is a great way to dilute them and improve their usability. They are often too strong to add to your skin neat and should be mixed and diluted first.



The benefits of essential oils

The benefits of these oils are as varied as the oils themselves, but there are some key themes.

Inhaling essential oils has been linked to reduces in stress, anxiety and depression as well as headaches, migraines and sleep disorders. Some have been found to sooth aches and pains, kill bacteria, reduce inflammation and sooth skin complaints. However, they are not side effect free so once you know which oils you want to use, it is important to find out its pros and cons.

Safety note– Essential oils are generally not safe to be ingested or used on skin in a neat form. When applied topically they may irritate or burn the skin unless properly diluted in a carrier oil or natural wax.
