Myrrh refers to the sap of a Mediterranean tree, which is collected by slashing its bark and capturing the running “tears” of resin. When fully dried, myrrh takes on a beautiful amber color and possessed an elegant and exotic fragrance. These qualities make myrrh a popular incense ingredient, alone or in combination with other herbs and resins. Ground myrrh resin is traditionally used to prepare salves and other topical formulations. It is also found in natural dental preparations, such as tooth powders and mouth washes.
