The sweet smelling aroma of the palo santo sacred wood is harnessed through the use of "smudging" to drive away negative energies from one's aura or home. It is believed that when the palo santo wood is lit it eliminates stagnant or negative energies and purifies the space, bringing uplifting positive energies, higher vibrations, and good luck. The soothing aroma of the smoke is often used to give your house a sweet smelling aroma and feel.
