Santalum album or Indian sandalwood is a small tropical tree, and is the most commonly known source of sandalwood. This species has historically been cultivated, processed and traded since ancient times.[clarification needed] Certain cultures place great significance on its fragrant and medicinal qualities. The high value of the species has caused its past exploitation, to the point where the wild population is vulnerable to extinction. Indian sandalwood still commands high prices for its essential oil, but due to lack of sizable trees it is no longer used for fine woodworking as before. The plant is widely cultivated and long lived, although harvest is viable after 40 years. Etymologically it is derived from Sanskrit Chandanam.
