Sandalwood is the name of a class of woods from trees in the genus Santalum. The woods are heavy, yellow, and fine-grained, and unlike many other aromatic woods, they retain their fragrance for decades. Sandalwood oil is extracted from the woods for use. Both the wood and the oil produce a distinctive fragrance that has been highly valued for centuries. Consequently, species of these slow-growing trees have suffered over-harvesting in the past century.[1]

Sandalwoods are medium-sized hemiparasitic trees, and part of the same botanical family as European mistletoe. Notable members of this group are Indian sandalwood (Santalum album) and Australian sandalwood (Santalum spicatum); others in the genus also have fragrant wood. These are found in India, Nepal, Bangladesh, Pakistan, Sri Lanka, Australia, Indonesia, Hawaii, and other Pacific Islands.

Various unrelated plants with similarly scented wood or oil include:

Production

Sandalwood leaf

Producing commercially valuable sandalwood with high levels of fragrance oils requires Santalum trees to be a minimum of 15 years old (S. album) the age at which they will be harvested in Western Australia – the yield, quality and volume are still to be clearly understood. Australia likely will be the largest producer of S. album by 2018, the majority grown around Kununurra, Western Australia. Western Australian sandalwood is also grown in plantations in its traditional growing area in the wheatbelt east of Perth, where more than 15,000 ha (37,000 acres) are in plantations. Currently, Western Australian sandalwood is only wild harvested and can achieve upwards of AU$16,000 per tonne, which has sparked a growing illegal trade speculated to be worth AU$2.5 million in 2012.[4]

Sandalwood is expensive compared to other types of woods therefore to maximize profit sandalwood is harvested by removing the entire tree instead of sawing it down at the trunk close to ground level. This way wood from the stump and root, which possess high levels of sandalwood oil, can also be processed and sold.[5]

Uses

Fragrance

Sandalwood (S. album) essential oil
Further information: Isobornyl cyclohexanol

Sandalwood oil has a distinctive soft, warm, smooth, creamy, and milky precious-wood scent. It imparts a long-lasting, woody base to perfumes from the oriental, woody, fougère, and chypre families, as well as a fixative to floral and citrus fragrances. When used in smaller proportions in a perfume, it acts as a fixative, enhancing the longevity of other, more volatile, materials in the composite. Last but not least, sandalwood is a key ingredient in the "floriental" (floral-ambery) fragrance family – when combined with white florals such as jasmine, ylang ylang, gardenia, plumeria, orange blossom, tuberose, etc.

Sandalwood oil in India is widely used in the cosmetic industry. The main source of true sandalwood, S. album, is a protected species, and demand for it cannot be met. Many species of plants are traded as "sandalwood". The genus Santalum has more than 19 species. Traders often accept oil from closely related species, as well as from unrelated plants such as West Indian sandalwood (Amyris balsamifera) in the family Rutaceae or bastard sandalwood (Myoporum sandwicense, Myoporaceae). However, most woods from these alternative sources lose their aroma within a few months or years.

Isobornyl cyclohexanol is a synthetic fragrance chemical produced as an alternative to the natural product.

Hinduism

Sandalwood paste is integral to rituals and ceremonies, to mark religious utensils, and to decorate the icons of the deities. It is also distributed to devotees, who apply it to their foreheads or the necks and chests.[6] Preparation of the paste is a duty fit only for the pure, so is entrusted in temples and during ceremonies only to priests.

The paste is prepared by grinding wood by hand upon granite slabs shaped for the purpose. With the slow addition of water, a thick paste results (called kalabham "കളഭം" in Malayalam language and "gandha" ಗಂಧ in Kannada), which is mixed with saffron or other such pigments to make chandanam. Chandanam, further mixed with herbs, perfumes, pigments, and some other compounds, results in javadhu. Kalabham, chandanam, and javadhu are dried and used as kalabham powder, chandanam powder, and javadhu powder, respectively. Chandanam powder is very popular in India and is also used in Nepal. In Tirupati after religious tonsure, sandalwood paste is applied to protect the skin. In Hinduism and Ayurveda, sandalwood is thought to bring one closer to the divine. Thus, it is one of the most used holy elements in Hindu and Vedic societies.

Jainism

Sandalwood use is integral part of daily practices of Jainism. Sandalwood paste mixed with saffron is used to worship tirthankar Jain Deities. Sandalwood powder is showered as blessings by Jain Monks and Nuns (Sadhus and Sadhvis) to their disciples and followers.

Buddhism

Sandalwood is mentioned in various suttas of the Pāli Canon.[7] In some Buddhist traditions, sandalwood is considered to be of the padma (lotus) group and attributed to Amitabha Buddha. Sandalwood scent is believed by some to transform one's desires and maintain a person's alertness while in meditation. It is also one of the more popular scents used when offering incense to the Buddha and the guru.

Islam

In sufi tradition, sandalwood paste is applied on the sufi’s grave by the disciples as a mark of devotion. It is practiced particularly among the Indian Subcontinent disciples. In the Tamil culture irrespective of religious identity, sandalwood paste or powder is applied to the graves of sufis as a mark of devotion and respect.[8]

Chinese and Japanese religions

Sandalwood, along with agarwood, is the most commonly used incense material by the Chinese and Japanese in worship and various ceremonies. However, Taoists are forbidden from using sandalwood (as well as benzoin resin, frankincense, foreign produced) incense and instead either use agarwood, or better still Acronychia pedunculata, in worship.[9]

Zoroastrianism

Zoroastrians offer sandalwood twigs to the firekeeping priests who offer the sandalwood to the fire to keep the fire burning. Sandalwood is offered to all of the three grades of fire in the fire temple, including the Atash Dadgahs. Sandalwood is not offered to the divo, a homemade lamp. Often, money is offered to the mobad (for religious expenditures) along with the sandalwood. Sandalwood is called sukhar in the Zoroastrian community. The sandalwood in the fire temple is often more expensive to buy than at a Zoroastrian store. It is often a source of income for the fire temple.

Medicine

Sandalwood essential oil was popular in herbal medicine up to 1920–1930, mostly as a urogenital (internal) and skin (external) antiseptic. Its main component is santalol (about 75%). It is used in aromatherapy and to prepare soaps.[10]

Technology

Due to its low fluorescence and optimal refractive index, sandalwood oil is often employed as an immersion oil within ultraviolet and fluorescence microscopy.

Distillation

Sandalwood is distilled in a four-step process, incorporating boiling, steaming, condensation, and separation. The process is known as steam distillation and is widely carried out industrially at Kannauj, India.

Food

Australian Aboriginals eat the seed kernels, nuts, and fruit of local sandalwoods, such as quandong (S. acuminatum).

Apart from this type, agarwood/aloeswood (Aquilaria malaccensis) then Aquilaria sinensis are the next best.
