Air oil is one of the set of Elemental oils including also Earth, Fire, Water and Spirit. The Air element is the principle of wind, speech, thought, ideas, inspiration, and joy, and Air oil could be used to magickally evoke any of these powers.
Air Element blows through the Crescent Moon, and since the New Moon rises at dawn, Air oil is formulated in the morning during the New Moon. Air is expressed in both the planets Jupiter and Mercury, so Air oil is made on Thursdays, reserving the Mercurial influence for Spirit. Air Element is corresponded to Yellow or Clear/White, easy to achieve in the Air oil with just my pale yellow base oils of Almond/Fractionated Coconut and the light, colorless essential oils affined to Air. When I make Air oil I face the East and the rising Sun.
These magick oils are also called ritual oils, anointing oils or condition oils. They can be used to anoint a person, candle, mojo bag, lucky coins, jewelry, amulets, statues, prayer or spell scrolls, or anything that has a connection with the purpose of the oil or the "condition" it is made to address. Use them according to your inspiration, imagination, the instructions in a book, your Spirit Guide, teacher or Angel's recommendations, or how your Grandma taught you.
