Palo Santo is a type of tropical wood that has a naturally pleasant aroma. It is burned, just like sage, for many different purposes and rituals. Palo Santo is often used for religious ceremonies, as well as for clearing out negative energy, spiritual healing, cleansing a particular space and relaxing the body and mind. It is also said to bring peace and happiness to the home. Palo Santo's scent is sweet, smooth and woody with a hint of spice.
