Aromatherapy is the art of using essential oils to help balance health. Three methods of application include:
Aromatically – Inhale directly from bottle, diffuse (with a diffuser), or from the palms of your hands.
Topically – Massage the oil into desired location. Depending on the oil you can do this neat (undiluted) or diluted with an organic carrier oil.
Another topical method is to fill a small spray bottle (1 oz or 2 oz) with 1:1 distilled water:witch hazel (alcohol-free) and add a few drops of essential oils. Shake bottle before each spritz.
Internally – Drop oil into an empty capsule and swallow with water. (This is the method I use with Oregano oil for parasites)
Or add a drop of oil to a small glass of water and drink.
I have discovered that quality varies from brand to brand. Some high-ranked companies include Doterra, Young Living, and deSensua.
