Copal is considered the Americas equivalent to Frankincense, used in many of the same ways, for the same reasons, to purify, protect and enhance spirituality.  It has been in use for hundreds of years, traditionally used in Mexico and South America for purification rituals. When smoldered on charcoal it produces a rich piney, lemony, clean and crisp aroma.  The next time you are bogged down with concerns, take a few minutes and waft the cleansing smoke around you, and visualize your cares evaporating.
