INTRODUCTION
World’s most popular and costliest wood is sandal wood. Sandal is widely known as Chandanamu, Srigandhamu in south India and Chandan in North. It is one of the renowned trees from ancient days. Hindus use this wood and its paste for pooja and religious use. Sandal wood is a small evergreen tree, and partial root parasite, attaining a height of 12-13 meters, with slender drooping as well as erect branching. The tree starts flowering at an early age of 2 to 3 years, Fruit is drupe, purplish, when fully mature and single seeded.

Sandal Scientific name is "Santalum Album"
This is Second Expensive Wood in the World. In Sandal Wood, the Heartwood of the Tree is treasured for its Aroma and used for Carving.
Sandal Wood Tree was Introduced to India around 4000 Years ago. Specially Hindus in India were using the Sandal Wood paste to make "Tilak" mark on Foreheads between eyes. Where the Third Eye is said to be located. It is mostly used by devotees of the Gods Shiva and Vishnu and protects the spot where Hindus believe power resides, as it cools the spot and the smell when combined with that of smoked sandalwood, clears the mind so that meditation can begin.
Below is recent Survey which happend to know about Sandal Wood Cultivation Growth in India.
Santalum album - INDIAN Sandal Wood
The fragrance of sandalwood is interwoven with Indian history and culture. The first mention of it in Indian literature is found around 2000 B.C. in the Ramayana. It was included with spices and silk among the first trade items with Middle Eastern and other countries. In 1792 sandalwood was declared a "Royal Tree" by the Sultan of Mysore, a status that continues today with the Indian government "owning" all the sandalwood trees.
Indian sandalwood's many uses include medicine, incense, burning of chips for ritual use, perfumes and beauty care products, and for carving religious and other artifacts.
Most Indian sandalwood grows on the Deccan Plateau in southern India, with the majority of the trees in the states of Karnataka and Tamil Nadu. Santalum album is found in dry, deciduous forests. It is considered a slow-growing tree and is easily damaged by fire, various pests, grazing pressures and diseases.
The amount of HEARTWOOD in a tree varies considerably depending on age, soil and climate conditions. The Essential oil found in the HEARTWOOD of the trees does not even start to form until the trees are at least 10 years old, and trees are not usually harvested until they are at least 30 years old. The HEART is yellowish to dark brown, with the lighter-colored wood containing higher levels and a better quality of essential oil than the darker wood. Oil content is also highest in the root and decreases as one moves up the tree. The highest concentrations of essential oil are found at the core of the HEARTWOOD, with decreasing amounts as one moves out from the center.
Sandalwood essential oil is mostly obtained by steam distillation (the practice of water distillation is considered outdated). It is colorless to pale yellow and somewhat viscous. The top note (the first aroma you smell) is very soft with a sweet-woody, balsamic body note and a long-lasting bottom note (which is why sandalwood is such a good fixative).
Santalum spicatum, AUSTRALIAN Sandalwood
While Australia has 5 native species of sandalwood, only 2 are considered commercially important, S.Spicatum and S.Lanceolatum.
The wood of both species was exported starting in the early 1800s, much of it to China. As demand grew and supplies of other sandalwoods dwindled, more and more trees were cut for export. The government in Australia first attempted to control the harvest of trees with the Western Australian Sandalwood Control Act of 1929. Also around this time, essential oil production from S. spicatum was systemized enough to control the quality so that it was considered therapeutically equivalent to East Indian oil. In 1932 S. spicatum was added to the British Pharmacopoeia.
S.Spicatum or Western Australian sandalwood was originally found across a large area of Western Australia from the arid interior to the woodlands. It is a small tree that grows to 20 feet tall. Australian sandalwood begins to bear fruit at 5 to 10 years of age, with flowering beginning in March or April. Trees mature much faster where there are higher levels of moisture (30 years to maturity) than in the dry regions (where trees may take 50 or more years to mature). Early over-harvesting and the conversion of forest to farmland in the regions with higher rainfall has eliminated most of the sandalwood trees in the area. Much of the replanting being done is in this region (the wheat belt) where the higher rainfall provides a better chance of success. Control of the sandalwood harvest and encouragement of plantation planting by the Western Australia government are being used to ensure a sustainable supply of Australian sandalwood.
The steam-distilled Australian sandalwood essential oil has chemical components similar to Indian sandalwood, but there are differences in levels of those constituents and in their respective aroma profiles. The most significant difference in make-up is that Indian sandalwood has much higher levels of santalol (25 to 30% versus 60 to 70%). The difference in the aroma of the two oils is most pronounced in the top note. Australian sandalwood has a more resinous, drier and less sweet top note than Indian sandalwood. The aroma of the two oils becomes more alike in the middle notes--and the all-important base notes are almost identical. In aromatherapy, Australian steam distilled sandalwood essential oil can be used the same as Indian sandalwood.
There are two types of Australian sandalwood oil being sold, one a true steam distilled essential oil and another that is solvent extracted or co-distilled oil. The co-distilled oil is produced by extracting ground sandalwood with hexane to create an oleoresin. The separation of the oil from the oleoresin ocurs during co-distilling under vacuum with a co-distilling agent and finally it is rectified. Steam distilled oil is produced using only heat and produces a oil that is more complex and characteristic of sandalwood. Aura Cacia sells only true steam distilled sandalwood essential oil.
Difference between INDIAN and AUSTRALIAN Sandalwood?
Of the 15 different species of sandalwood that grow throughout the world, there are 2 main varieties that are traded internationally. These are Santalum spicatum (Australian sandalwood) and Santalum Album (Indian sandalwood). Australian sandalwood does produce a lower oil content than Indian sandalwood although it consistently produces the oil forming heartwood from a very young age.
How much oil does one tree produce?
Oil yield in sandalwood trees varies between species. The oil is present only within the heartwood of the tree. The older the tree, the larger percentage of heartwood exists within the tree therefore the more oil is present within a given tree. On average, Australian sandalwood produces between 3 to 3.5% oil within the heartwood and Indian sandalwood between 3.5 and 5%, in its lifetime.
An interesting Fact:
At the time of Mahatma Ghandi's death in 1948, there was not enough sandalwood in India for his funeral pyre, so logs of Santalum album were imported from Australia for the state funeral ceremony.
