Called "Holy Wood" by traditional peoples, Palo Santo is used for cleansing, purifying, and banishing. Used widely by shamans and healers, this 'holy wood' brings in peace, harmony, luck and protective energies. Palo Santo is different than many of the other burnable herbs as it is fragrant in its raw form and does not necessarily need to be lit, though it usually is when being used for ceremonial purposes. Palo Santo is often used by Amazonian shamans in sacred plant spirit ceremonies; the rising smoke of the lit sticks is believed to enter the energy field of ritual participants to clear misfortune, negative thoughts, and to chase away evil spirits. Its use reportedly dates back to the Inca era.
