How to use them
There are lots of ways to use essential oils, some of the most common are topically, by ingestion and aromatically.
There is great evidence that essential oils are absorbed into the bloodstream when inhaled. The large amount of blood vessels in the lungs absorb the oils and then circulate them throughout the body.
Using a diffuser can help you experience the benefits of essential oils. You can diffuse lavender to reduce stress, melaleuca to cleanse the air, wild orange to improve mood, frankincense for spiritual enlightenment and peppermint to improve focus and energy.
In most cases (even if you're just adding the essential oils to a bath), you'll need a carrier oil—a neutral, plant-based oil that can act as a base. Common carrier oils include sweet almond, jojoba, olive, sunflower seed, avocado, and grapeseed.
Essential oils are extremely small so they can pass through the skin and into the body quickly. But if you want to keep the oils on your skin and dilute them to create more gentleness on the skin you can combine them with carrier oils.
These larger oils that come from the fatty part of the plant can increase the length of time the essential oils stay on your skin and also prolong the aromatherapy effects.
The most utilized type of diffuser for essential oils today is an ultrasonic diffuser. This type uses ultrasonic waves and water to disperse essential oils into the air.
