Sandalwood

Sandalwood is a special tree.

It has a very nice smell. This scent can last for many years. People take oil from the wood.

This oil is used in soaps and perfumes. Some people use the wood to carve statues.

The wood is heavy and yellow. It is one of the most expensive woods in the world. These trees grow very slowly. Because they are so useful, people must be careful not to cut too many down.

Sandalwood is a special type of wood.

It comes from trees in the Santalum group. These trees grow very slowly. The wood is heavy and yellow. It also has a very strong scent.

This smell can last for many years. People take oil from the wood. This is called essential oil.

People use this oil in soaps and perfumes. It helps other smells last longer. Some people also use the wood to carve statues.

This is because the wood is easy to carve.

Sandalwood is one of the most expensive woods. Because it is so valuable, some trees have been cut down too much. This is called over-harvesting. In the past, many trees in Hawaii were lost this way. In India, the government controls how people harvest the trees. In Australia, many trees are grown in large farms called plantations. One type of sandalwood is Santalum album. It is found in parts of India and Indonesia. It is often used for medicine and religion. Another type is Santalum spicatum. This one grows in Australia. It is used to make many scents for people to enjoy.

Sandalwood is a very special kind of wood.

It comes from trees in the Santalum group. These trees are known for being heavy and yellow. They have a very fine grain. Most importantly, they have a wonderful smell. This scent is very strong and smooth. Unlike many other fragrant woods, it stays smelling good for decades.

Because it is so valuable, it is one of the most expensive woods in the world. This high value makes it a very important part of many cultures.

People use sandalwood in many different ways. They extract a liquid called essential oil from the wood.

This oil has a warm and creamy scent. Perfumers use it to make scents last longer. It acts as a fixative for other smells. In India, the oil is used a lot in cosmetics. Some people also use the wood for carving.

It is a great choice for making statues of Hindu gods. Even scientists use the oil under special microscopes to see things more clearly.

History shows how far sandalwood has traveled. The name comes from the Sanskrit word "Chandana." This means "wood for burning incense."

Long ago, Austronesian traders carried these trees across the sea. They spread the trees through trade routes like the Maritime Silk Road. By 1300 BCE, sandalwood was already growing in South India. In the 1840s, it was the biggest export for Western Australia. These trees have been part of human trade for a very long time.

There are many different types of sandalwood trees.

Santalum album is a very famous species. It is found in India and Indonesia. It is often used for medicine and religious ceremonies. Another type is Santalum spicatum from Australia. This species is grown in large plantations. In 2017, one company in Australia controlled about 80% of the world's supply of Indian sandalwood. Some trees, like the Hawaiian sandalwood, were harvested so much that they ran out of supply between 1790 and 1825.

It is important to protect these slow-growing trees. Because they are so valuable, some people cut them down too much. This is called over-harvesting. In the past, this happened in Hawaii and Tonga. In India, the government now controls the harvest to keep trees safe.

Today, many people grow sandalwood on organized farms. This helps make sure we do not run out. By 2030, India hopes to grow much more sandalwood. This will help provide the wood and oil in a way that is safe for nature.

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.
