Ancient Egyptian history tells us that myrrh comes from the tears of Horus the Sun God.  
Myrrh is a shrub (this denomination indicates various species of Commiphora, of the Burseraceae family) which originates form the arid and semiarid regions of East Africa, Arabia and the Indian sub-continent.

The oil is obtained from the resin of this thorny bush which grows in very dry desert areas. Myrrh has been used since ancient times as a sacred incense, as a fragrance and as a therapeutic agent. It has a rich, smoky, and balsamic  aroma. Myrrh has a calming effect on the nervous system, settles the mind and purifies the spirit. It is said that myrrh forms a bridge between “the sky and the earth”. Some species are used for medicinal purposes whilst others for their fragrance.

These two different types of myrrh, medicinal and fragrant both come from the tradition of the same Hebrew word – MOR. The fragrance of myrrh permeates the pages of the Book of Solomon which contains more references than any other book from the Bible. The Song of Solomon has 7 references.

In ancient times, myrrh resin was the subject of myths and legends, full of meanings and historical references. In ancient Greece, it was the most significant symbol of seduction, whilst for the Hebrews (as in the offering of the Three Kings) it held the meaning of returning to God.
Myrrh essence and resinoid can also be obtained from the shrub.
A fresh citrus note with a brushwood dry down, it is used in fougère and chypre compositions.
