Abramelin oil is used in many magical rituals and its recipe derives from the Grimoire "The Sacred Magic of Abramelin the Mage.
This blend is most sacred among Ceremonial Magicians, Thelemites, and members of the Gnostic Catholic Church. Its popularity became widespread after the publication of “The Book of the Sacred Magic of Abramelin the Mage”, by S. L. MacGregor Mathers in 1897, and its use by Aleister Crowley in 1904. The blend is used to consecrate both the Magician and his or her tools. Prior to any working, one should place a drop of Abramelin Oil upon the forehead, in the location of the third eye.
