Palo Santo is used in rituals to cleanse and ward off negative energies. The wood is also used to communicate with the divine, heal on the physical and spiritual levels, and improve concentration and mental focus during meditation.
To use it, light a stick, wait about thirty seconds, and blow out the flame. The end will continue to smolder, releasing dense, white, fragrant smoke. Carry this around the area you wish to cleanse, waving the smoke with your hand or a hand fan to make sure it gets into all of the corners. As you do this, state your intention.
