Myrrh has been used as a medicinal herb for thousands of years. It is mentioned several times in the Bible, in writings as old as Psalms and the Song of Solomon, and of course it is well known as one of the three gifts that the Magi brought to Jesus Christ.’ Despite this ancient record of use, clinical trials on mjTrh were lacking until recently when a group of Egyptian scientists examined its value in the treatment of fascioliasis (liver fluke).^ Since then, a numher of other clinical studies have been published that suggest the clinical use of myrrh represents a significant advance in the herbal treatment of parasites. What is particularly interesting is that myrrh seems to he active against parasites that infest deeper in the hody than the gut, such as in the liver and bladder {the latter in the case of sehistosomiasis). What is Myrrh? The name “myrrh” is probably derived from the Arabic or Hebrew word “mur,” which means bitter. Myrrh (Arabian or Somali Myrrh) is an oleo-gum resin, obtained from the stem of various species of Commiphora (Burseraceae) growing in northeast Africa and Arahia. Texts have traditionally given the principal source as C molmol, but the chief source today is C. myrrha.’^ Almost all memhers of the Burseraeeae possess oleoresin canals in the phloem, and when cracks and fissures form in the bark, the resin exudes spontaneously. This yellowish-white viscous fluid soon hardens in the heat to reddish-brown crystalline masses. In some cases, incisions are made in the bark to encourage the resin production.^ Chemical Composition Myrrh is composed of a volatile (essential) oil (two to ten percent), including sesquiterpenes, an alcohol-soluble resin (25 to 40%) containing eommiphoric acids and a water-soluble gum (30 to 60%).*
