Sandalwood refers to a class of heavy, fine-grained woods from trees in the genus *Santalum*.

These trees are famous for their distinctive, creamy, and milky fragrance. Unlike many other aromatic woods, sandalwood retains its scent for many decades. Because of this lasting aroma, it is often cited as one of the most expensive woods in the world. The wood and its extracted oil are highly valued for religious, medicinal, and commercial uses. This high value has made sandalwood a major part of global trade for centuries.

The biological mechanism of these trees is quite unique. Sandalwood trees are medium-sized hemiparasitic trees. This means they are part of the same botanical family as European mistletoe. As hemiparasites, they rely on other plants for certain nutrients. To produce commercially valuable oil, *Santalum album* trees must reach a minimum age of 15 years. The yield and quality of the oil depend heavily on the age and location of the tree. Generally, older trees provide the highest oil content and best quality.

There are many different species within the *Santalum* genus, though they differ in quality and origin. *Santalum album* is the most famous species and is considered the best for religious and medicinal purposes. It is native to the dry tropical regions of India and Indonesia. Another important species is *Santalum spicatum*, which is native to Australia. Merchants often market *S. spicatum* because it comes from stable, managed sources. Other species include *S. ellipticum*, *S. freycinetianum*, and the Hawaiian sandalwood, *S. paniculatum*.

While these species are also fragrant, they have faced different levels of availability.

The history of sandalwood is deeply tied to ancient maritime trade. The name is etymologically derived from the Sanskrit word *Chandana*, meaning "wood for burning incense." This term is related to words meaning "shining" or "glowing." Austronesian traders introduced *S. album* to mainland Asia in ancient times. It spread through the incense trade route and the Maritime Silk Road. By at least 1300 BCE, the tree had become naturalized in South India. In the 1840s, sandalwood became Western Australia's largest export earner.

The economic significance of sandalwood is reflected in its high market prices. In 2017, sandalwood oil prices had risen to $3,000 per liter. The cost varies between species; for example, Australian sandalwood oil sold for around $150 per liter. However, Indian sandalwood oil is more expensive due to its higher alpha-santalol content, costing about $250 per kg. In the late 1990s, Australian sandalwood oil saw a major revival. By 2009, production peaked at more than 2,000 tonnes per year. Much of this supply was sent to the fragrance industries in Europe.

Sandalwood has many specialized uses across different industries. In perfumery, the oil acts as a fixative. This means it helps other, more volatile scents last longer on the skin. It is a key ingredient in the "floriental" fragrance family. Beyond scent, the wood is excellent for carving. It is traditionally used to create statues of Hindu gods. Even in science, the oil has a role. Due to its refractive index, it is used as an immersion oil in ultraviolet and fluorescence microscopy.

However, the high demand for sandalwood has led to serious ecological challenges. Many species have suffered from over-harvesting in the past. Between 1790 and 1825, the supply of Hawaiian sandalwood was completely depleted. In Tonga, the population of sandalwood trees collapsed because of changes in social harvesting systems. In India, while the government controls the harvest, many trees are still illegally cut down. To combat this, ethical plantations are rising. India expects to increase its supply manyfold by 2030 due to favorable weather and competitive pricing.
