Lavender Essential Oil

Lavender oil has been around for centuries. It’s said that the name comes from the Latin word “lavare”, which means “to wash”, or from the word “livendulo”, which means “livid or bluish”. It’s been used all over the world for a number of different uses, and is certainly one of the most popular essential oils today.

Although one of the most calming essential oils, lavender has a number of different effects. In ancient Egypt, it was often used for embalming and cosmetic purposes. In ancient Rome, lavender was touted for its healing and antiseptic properties, and in the middle ages, it was used throughout England to make furniture polish and to help make clean clothes smell good (we still have lavender scented laundry detergent today!)[i]

Interesting fact! When the tomb of King Tut was opened, there were jars found that contained materials resembling lavender. This is a callback to the use it as an embalming property in the ancient world.[ii]

It’s also been shown in studies to improve symptoms and issues associated with PTSD, such as poor sleep, low mood, and anxiety. Click here to listen to more! 


Chamomile Essential Oil

Chamomile has been used therapeutically throughout history, and as early as the 1st century CE for digestive complaints. Like lavender, its uses varied across different areas of the world, but some of its main uses include cosmetically and to calm a variety of different ailments. It’s a very gentle oil that is even great for use with children.

There are two main types of chamomile: Roman and German. Roman chamomile is native to Western Europe and northern Africa, but is now harvested worldwide in different temperate regions. German chamomile is native to Europe and northwest Asia, and still grows wild there today.

Interesting facts! A book publishing in 1911 called Herb Garden claims that chamomile has a remarkable effect on other plants to keep them vibrant and lively, and it’s actually been called the “plant’s physician”. If it can keep plants healthy, imagine what it can do for you!

Ylang ylang has a long history of use, but its medicinal properties weren’t recognized until the beginning of the 20th century when it was used to treat a variety of diseases like malaria, typhus, and intestinal distress.

How to use essential oils?

Now that we know what some of the different essential oils are used for, how do we actually use them? Essential oils have a number of different uses and purposes but for the therapeutic benefits we mentioned above, the best way to take advantage of all they have to offer is through aromatherapy. In today’s world, this is easier than ever with the production of essential oils diffusers that allow you to enjoy the benefits and pleasantries of aromatherapy in an easy and convenient way.

When it comes to diffusers, there are two main types: heat and vapor. If you’re new to the essential oil world, or just want to consider your options, it’s important to know the pros and cons of both kinds of diffusers so that you can make the right choice for you.

Let’s look first at heat diffusers. These are often the cheaper option when it comes to diffusers. They have the added benefit of being completely silent in a room so you don’t even notice when it’s working away at your oils. Not all heat diffusers are made the same, but the best ones will produce very low levels of heat and more subtle aromas. However, some heat diffusers use high levels of heat to produce stronger smells, but this can alter the chemical constituents of the oil. All heat diffusers have one major drawback: they share the potential of fractioning the oil into its different components because of the application of heat. This means that the whole oil won’t get into the air, and since the oil becomes divided or broken down, you won’t get the same therapeutic effects of that oil, which essentially negates the purpose of diffusing the essential oil for aromatherapy. However, they do still diffuse the oils for a pleasant smell in the room.

Vapor diffusers, on the other hand, use no heat whatsoever. Instead, they use jets of air to pull the oils from the bottom to the top of a tube and dispels them in a fine mist or spray. This type of diffusion allows the whole oil to be dispersed into the air in the form of tiny droplets. The oil is not split at all or broken down into different constituents, meaning you get the whole benefit of the whole oil. In terms of aromatherapy benefits, this is definitely the way to go. They have a bit of a hum to them when they are functioning due to the fact that they are working so powerfully to quickly saturate the air with the essential oil scent and benefits that you desire.

Vapor diffusers have one major obstacle for people: they usually cost more than heat diffusers. However, if you are wanting to enjoy the benefits of aromatherapy and spend the money on getting essential oils, you want to make sure you are using a diffuser that doesn’t harm or split those oils. You want to make sure you have a diffuser that uses the oils to the best of their ability and allows you to get your money’s worth, while at the same time allowing you to enjoy their health benefits and wonderful scents. It’s like buying a new TV: you wouldn’t buy one that looks great but lacks a picture or has no ability to produce sound. If you’re going to enjoy essential oils, make sure you get the right equipment in place. 

When you’re using diffusers, dilute the oil you want in a some water and simply turn the diffuser on – that’s it! You can blend together different oils to create a pleasing scent, though we would recommend making sure you mix oils from the same therapeutic benefit groups. For example, don’t mix a calming oil with an energizing one if you are hoping to get relaxation out of the aromatherapy. There are lots of great blends you can make online with individual oils, and also lots of pre-made blends in store or online here!
