Myrrh gum resin is harvested from Commiphora myrrha, a low growing, desert tree that exudes a viscous yellow gum, which hardens into a reddish-brown resin.
Frankincense resin is gathered by making incisions in the small, deciduous tree, Boswellia sacra. The yellow-hued pitch is often used as incense or in perfumery. Frankincense has been considered an herb of spirituality with lore dating back thousands of years. The aromatic resin can be used alone or blended into incense formulas.
