Abramelin oil, also called Oil of Abramelin, is a ceremonial magic oil blended from aromatic plant materials. Its name came about due to its having been described in a medieval grimoire called The Book of Abramelin written by Abraham the Jew. The recipe is adapted from the Jewish Holy anointing oil of the Tanakh, which is described in the Book of Exodus attributed to Moses.
Abramelin oil became popular in the Western esoteric tradition in the 20th century after the publication of the S. L. MacGregor Mathers English translation of the Book of Abramelin, and especially via Aleister Crowley, who used a similar version of the oil in his system of Magick. There are multiple recipes in use today and the oil continues to be used in several modern occult traditions, particularly Thelema and the Ecclesia Gnostica Catholica.
One part of the best myrrh, half a part of cinnamon, one part of cassia, one part galanga root, and a quarter of the combined total weight of good, fresh olive oil. Make these into an ointment or oil as is done by the chemists. Keep it in a clean container until you need it. Put the container together with the other accessories in the cupboard under the altar.
