The sacred tree, also known as palo santo (Bursera graveolens), contains a powerful essential oil that strengthens the immune system and fights inflammation. It belongs to the same botanical family (Burseraceae) as incense and myrrh plants, which contain valuable oils rich in antioxidants used worldwide. The Bursera graveolens produces a prized fruit in the form of a small black seed wrapped in a red mass and enclosed in a green capsule. WHAT DOES PALO SANTO SMOKE SMELL LIKE? Palo santo is now common as a form of incense, emitting aromas reminiscent of baked apples or burnt sugar. When burned, it produces a delightful aroma that raises the vibration of personal energy. It also cleanses rooms in the house, prepares for meditation, and provides a deeper connection with the deeper self. The fruit of the palo santo tree emits a smell similar to fennel, somewhat sweet.
