Myrrh is a tree in the Commiphora genus, mainly harvested in the regions of Ethiopia, Somalia, and Arabia. With normally available myrrh, when its bark is pierced, it produces and flows the resin to the wounded spot to solidify and heal.
Our myrrh is the "suhul" variety ("suxul" in the Somali language) - meaning sustainably harvested. In normally available commercial grades of myrrh, the bark is pierced by a knife, forcing the tree to flow the gum-resin. With our suhul variety, the collectors in Somalia patrol thousands upon thousands of acres to find trees with natural breaks in their barks, such as weak points in the branches, their own thorns piercing, damage done by storms or wildlife, etc, and collect the resin that has naturally flowed off - and not encouraged to be produced by piercing with a knife. This is a far more healthy way to collect incense as there is no intentional damage done to the tree, and only the excess resin is collected. You may enjoy the scent knowing it was consciously collected.
Myrrh has a rich and ancient history in the Near East dating back to biblical times, being worth even more than its weight and gold - and far before this time as well. Records exist of ancient Egyptians importing myrrh as far back as five thousand years ago.
