Palo Santo - Healing wood is one of the most important trees used by the Incas and native people of the Andes as a spiritual remedy for purifying and cleansing. The Palo Santo tree belongs to the same family (Burseraceae) as frankincense and myrrh.
The essential oil of palo santo is responsible for the unique fragrance of this wood, and contains resins that are rich in the sesquiterpene class of compounds, most notably limonene. It also contains the fragrant compounds non-amine and germacrene. In one published Cuban medical study, components in the essential oil inhibited the growth of a specific type of breast cancer, MCF-7. Palo santo essential oil is significantly anti-bacterial, which probably explains its traditional use as an incense wood for dispelling bad energy.
