Myrrh resin is a natural gum that exudes from naturally occurring cracks in the small, thorny C. molmol busy. The ducts within the plant, hold the gum resin, and when incised can generate more resin and increase the yield of the plant. Collection is made following the incision, when the dried gum is about the size of a walnut. Myrrh Essential Oil is steam distilled from the myrrh resin. The color of the oil is pale-yellow to pale orange. It has a warm, sweet, slightly musty, earth-like, spicy aroma.
