Time to bust out the diffuser.
For centuries, people across the globe have understood the benefits of essential oils. There is evidence they were utilized as far back as ancient Egypt in mummification and ceremonial celebrations, and these highly revered oils have even been used as currency throughout history.
Essential oils are still in use today for many purposes. Their pleasant aromas make them ideal for fragrances and perfumes, and they are still prized for their potential health benefits. Diffusers are a popular way to experience essential oils, along with topical and internal usage.
Note: it is very important to always read the label as some oils cannot be taken orally or used directly on skin.
Here are the top 9 essential oils for 2019.
Lavender’s sweet smell makes it one of the most well known and recognized of all essential oils. Its distinctive purple color makes lavender a favorite in home gardens, and its leaves are also frequently collected, dried, and used for a variety of purposes.

Orange Essential Oil
The orange is one of the most common citrus fruits and subsequently one of the most popular essential oils. A hybrid between two other citrus fruits, a mandarin and pomelo, the orange’s origins go back to ancient China, where it was first mentioned in literature around 314 BCE.
The Spanish are believed to have brought the orange to North America and likely planted the first tree in Hispaniola, the island of modern-day Haiti and Dominican Republic. Oranges became popular amongst sailors once it was realized that the vitamin C in an orange could help prevent the dreaded scurvy.
As an essential oil, its sweet, relaxing, and familiar scent creates a pleasant environment. It can be applied topically, diffused, or consumed orally. The oil is extracted from the rind.

Rosemary contains polyphenols, which have antioxidants, anti-inflammatory, cholesterol-lowering and glucose-stabilization properties.
