Palo santo (Bursera graveolens) is an attractive aromatic tree whose wood is valued for its fragrance. The wood of this tree is used all over Central and South America in the form of incense. The natives of the region like the Inca use the wood of this tree spiritually to rinse out all impure energy and also to eliminate evil spirits, misfortune and calamity. While the palo santo tree is said to possess very potent energy, when the tree is burned, its aroma gives a sense of wellbeing, peace and relaxation.

You can burn palo santo wood just like incense by lighting the wood shavings. Alternatively, you can also light a stick of palo santo on fire and extinguish the flame after some time so that it generates an aromatic scent. A medicine man (shaman) in Peru often lights palo santo sticks and allow the rising smoke to spread so that the aromatic smoke engulfs the ritual participants with a view to get rid of all evil spirits, misfortunes and negative thought patterns.
