Myrrh is a red-borwn resinous material, the dried sap of the Commiphora myrrha tree, indigenous to Somalia. It is a constituent of perfumes and incense, and was highly prized in ancient times.
A number of other Commiphora or Balsamodendron saps are also known as myrrh, including that from Commiphora erythraea (sometimes called East Indian myrrh), Commiphora opobalsamum, and Balsamodendron kua.
