The branches of a young sandalwood tree found in Hawaii
'Sandalwood' is the fragrant
wood of
trees in the genus ''
Santalum''. Species of this tree are found in
Nepal, southern
India,
Sri Lanka,
Hawaii,
South Pacific islands and
Australia. It is used as fragrance in
perfume and
incense, and for
woodworking. Some temples have been built with sandalwood in
India and these retain the aroma for centuries. Jewelry boxes,
fans, and ornate carvings continue to be made in many parts of Asia, especially India, using sandalwood.

, or Nepalese sandalwood, is currently endangered and consequently very expensive. Although all sandalwood trees in Nepal are government-owned and their harvest is strictly controlled, many trees are illegally cut down and smuggled out of the country. Sandalwood
essential oil prices have risen up to $1000-1500 per kg in the last 5 years. Some countries regard the sandal oil trade as ecologically harmful because it encourages the overharvesting of sandalwood trees. Sandalwood from
Mysore region of
southern India is generally considered to be of the highest quality available. New
plantations have been set up with
international aid in
Tamilnadu, in order to facilitate the economic benefits of sandalwood.
★ ''Santalum ellipticum'', known as Hawaiian sandalwood ('' ‘iliahi alo‘e ''), is also used and deemed of high quality.
★ ''
Santalum spicatum'' (Australian sandalwood) is used by some
aromatherapists and perfumers. The concentration of constituent chemicals in its essential oil - and hence, its aroma - differ considerably from those of other ''Santalum'' species.

West Nepal sandalwood ''(Amyris balsamifera)'' is not a member of the sandalwood family; the chemical components of amyris
essential oil are different from those of the oil obtained from plants in the ''Santalum'' genus.
Production
To produce commercially valuable sandalwood with high levels of fragrance oils, harvested ''santalum'' trees have to be at least 40 years of age, but 80 or above is preferred. However, inferior sandalwood produced from trees at 30 years old can still fetch a decent price due to the demand for real sandalwood.
Unlike most trees, sandalwood is harvested by toppling the entire ''santalum'' tree instead of sawing them down at the trunk. This way, valuable wood from the stump and root can also be sold or processed for oil.
Use
Fragrance
Sandalwood
essential oil provides perfumes with a striking wood
base note. Sandalwood smells not unlike other wood scents, except it has a bright and fresh edge with few natural analogues. When used in smaller proportions in a
perfume, it is an excellent
fixative to enhance the head space of other fragrances.
Religious use
In
Hinduism, sandalwood is often used for rituals or ceremonies. Its use as a
embalming paste is used in
Lord Shiva temples on
Shivlings. A vast majority of hindus wear a small mark of this paste on their forehead right above the middle of the eyes. It is supposed to keep the 'third eye' (
pituitary gland) cool.
Sandalwood is considered in
alternative medicine to bring one closer with the divine. Sandalwood
essential oil, which is very expensive in its pure form, is used primarily for
Ayurvedic purposes, and treating
anxiety.
It is said to have been used for embalming the corpses of princes in
Ceylon since the
9th century.
In
Buddhism, sandalwood are considered to be of the ''Padma'' (
lotus) group and attributed to the
Bodhisattva Amitabha. Sandalwood scent is believed to transform one's desires and maintain a person's alertness while in
meditation. Sandalwood is also one of the more popular scents used for
incense used when offering incense to the Buddha.
Sandalwood, along with
agarwood, is the most popular and commonly used incense material by the
Chinese and
Japanese in worship and various ceremonies. It is also used extensively in
Indian incense, religiously or otherwise.
Firekeeping priests, who have maintained sacred fires for centuries, accept sandalwood twigs from
Zoroastrian worshippers as their contribution for sustaining the fire.
Medicine
Sandalwood essential oil was popular in medicine up to 1920-1930, mostly as urogenital (internal) and skin (external) antiseptic. Its main component
santalol (~90%) has
antimicrobial property.
It is used in
aromatherapy and sandalwood oil is also used to prepare soaps.
Technology
Due to its low
fluorescence and optimal
refractive index, sandalwood oil is often employed as an immersion oil within ultraviolet and
fluorescence microscopy.
