Sandalwood is a class of woods from trees in the genus Santalum. The woods are heavy, yellow, and fine-grained, and unlike many other aromatic woods, they retain their fragrance for decades. Burning sandalwood incense can benefit healing work by promoting a deeper relaxed state in the healer, increasing spiritual energy. Sandalwood also relaxes the heart and throat chakras. Burned to exorcise demons and evil ghosts, conjure beneficial spirits, and promote spiritual awareness.
