Sanalwood is the name for several fragrant woods and their essential oil. Most are medium-sized hemiparasitic trees of the Santalaceae family of the genus, Santalum. The most notable members of this group are Santalum album, Indian Sandalwood and Santalum spicatum, Australian sandalwood. Several other members of the genus species also have fragrant wood and are found across India, Australia, Indonesia and the Pacific Islands. Sandalwood has been valued for centuries for its fragrance, woodworking and for various purported medicinal qualities.
