Myrrh is a resin, or sap-like substance, that comes from a tree called Commiphora myrrha, common in Africa or the Middle East. Myrrh is botanically related to Frankincense, and is one of the most widely used essential oils in the world.
It has been used throughout history as a perfume, incense and medicine. It can also be ingested by mixing it with wine. When a tree wound penetrates through the bark and into the sapwood, the tree bleeds a resin. Myrrh gum, like frankincense, is such a resin.
Myrrh Essential Oil smells more pleasant than the resin, but I still find the aroma of the oil to be a bit harsh on its own. The aroma of Frankincense Oil helps to round out and freshen the aroma Myrrh Essential Oil. The aroma is woody, earthy and a bit balsmic.
