What is Sandalwood?

A Prized Aromatic Wood

Sandalwood refers to a distinct class of woods derived from trees within the genus Santalum. These woods are characterized by their substantial weight, yellowish hue, and fine grain. Uniquely among aromatic woods, sandalwood retains its captivating fragrance for many decades, a property that has made it highly sought after across centuries. The valuable sandalwood oil, a key product, is meticulously extracted from these woods.

One of the World's Most Expensive Woods

Consistently ranked among the most expensive woods globally, alongside species like African blackwood, pink ivory, agarwood, and ebony, sandalwood's high value is a testament to its unique properties and cultural significance. This considerable demand, coupled with the slow growth rate of these trees, has unfortunately led to historical over-harvesting of certain species, posing significant conservation challenges.

Nomenclature

Etymological Roots

The name "sandalwood" and the taxonomy of the genus Santalum are deeply rooted in the species' extensive historical and global usage. The term ultimately originates from the Sanskrit word Chandana (เคšเคจเฅเคฆเคจ), which translates to "wood for burning incense." This term is further connected to candrah, meaning "shining, glowing," and the Latin candere, also signifying "to shine or glow."

Journey to English

The word "sandalwood" made its way into the English language during the 14th or 15th century, having traversed through Late Greek, Medieval Latin, and Old French. This linguistic journey reflects the long-standing global trade and cultural exchange associated with this precious wood, highlighting its enduring presence across diverse civilizations and historical periods.

True Sandalwood Species

Botanical Characteristics

True sandalwoods are medium-sized, hemiparasitic trees, meaning they obtain some of their nutrients by attaching to the roots of other plants. They belong to the same botanical family as the European mistletoe. These species are indigenous to Insular Southeast Asia, Melanesia, Australia, and the Pacific Islands.

Santalum album (Indian Sandalwood)

  • A threatened species native to dry tropical regions of Indonesia (Java and the Lesser Sunda Islands), the Philippines, and Western Australia.
  • Introduced to East Asia, Mainland Southeast Asia, and South Asia by Austronesian sailors during the ancient spice trade, becoming naturalized in South India by at least 1300 BCE.
  • In India, principal sandal tracts are found in Karnataka and adjoining districts of Maharashtra, Tamil Nadu, Kerala, and Andhra Pradesh.
  • Despite government ownership and harvest control in India, Pakistan, and Nepal, illegal logging remains a significant issue.
  • Sandalwood oil prices reached US$3,000 per liter by 2017, reflecting its high demand and scarcity.
  • Still considered to possess the best and original quality, especially for religious and alternative medicine applications.

Pacific & Australian Varieties

Beyond S. album, several other species within the Santalum genus are recognized for their fragrant wood, each with its own history and commercial significance.

  • Hawaiian Sandalwood ('iliahi)

    • Includes S. ellipticum, S. freycinetianum, and S. paniculatum.
    • Highly valued and exploited between 1790 and 1825, leading to depletion.
    • While S. freycinetianum and S. paniculatum are relatively common today, they have not regained their former abundance or size, and S. ellipticum remains rare.
    • A fourth species, S. haleakalae, is found only in subalpine areas and was never commercially exported.
  • Santalum yasi

    • A distinct sandalwood species native to Fiji and Tonga.
  • Santalum spicatum (Australian Sandalwood)

    • Widely utilized by aromatherapists and perfumers, though its oil concentration differs from other Santalum species.
    • Historically, it was Western Australia's largest export earner in the 1840s.
    • Production of Australian sandalwood oil saw a revival in the late 1990s, peaking at over 20,000 kg per year by 2009, with much going to European fragrance industries.
    • By 2011, a significant portion was directed to the chewing tobacco industry in India, which remains a major market for both Indian and Australian sandalwood oils.

Unrelated "Sandalwoods"

It is important to distinguish true sandalwoods from various unrelated plants whose scented woods are also commercially referred to as "sandalwood." These species, while aromatic, do not belong to the Santalum genus and often lack the enduring fragrance of true sandalwood.

Examples of unrelated plants marketed as "sandalwood" include:

  • Adenanthera pavonina (sandalwood tree, red or false red sandalwood)
  • Baphia nitida (camwood, African sandalwood)
  • Eremophila mitchellii (sandalwood; false sandalwood, sandalbox)
  • Myoporum platycarpum (sandalwood; false sandalwood)
  • Myoporum sandwicense (bastard sandalwood, false sandalwood)
  • Osyris lanceolata (African sandalwood)
  • Osyris tenuifolia (East African sandalwood)
  • Pterocarpus santalinus (false red sandalwood, growing in southern Indian regions)

Critical Note: Most woods from these alternative sources tend to lose their aroma within a few months or years, unlike the decades-long fragrance retention of true Santalum species.

Production & Economics

Maturation and Yield

To produce commercially valuable sandalwood with high concentrations of fragrant oils, Santalum album trees must reach a minimum age of 15 years. The precise yield, quality, and volume of oil are still subjects of ongoing research. Generally, older trees are observed to yield higher oil content and superior quality. India continues to be a producer of high-quality Santalum album, with ethical plantations increasing and expected to significantly boost supply by 2030.

Global Production Landscape

Historically, India was the world's largest producer of sandalwood, but over-exploitation led to a decline in the 21st century. Australia has since surpassed India, becoming the largest producer of S. album, with the majority cultivated in plantations around Kununurra, Western Australia. As of 2017, Quintis (formerly Tropical Forestry Services) controlled approximately 80% of the global Indian sandalwood supply. Western Australia also boasts the world's largest plantation resource for Australian sandalwood (S. spicatum) in its wheatbelt region.

Harvesting and Valuation

Sandalwood's high market value dictates specific harvesting practices. To maximize profit, the entire tree, including the stump and root, is removed rather than merely felling at ground level. This is because the stump and root contain high levels of the prized sandalwood oil. Australian sandalwood is typically sold in log form, graded by heartwood content, and uniquely, its white sapwood does not require removal before oil distillation. In contrast, Indian sandalwood, primarily used for oil extraction, necessitates sapwood removal prior to distillation.

As of 2020, the market prices for sandalwood oils reflected their distinct chemical compositions and perceived quality:

  • Australian Sandalwood Oil (S. spicatum): Approximately US$1,500 per kilogram (US$3,307 per lb).
  • Indian Sandalwood Oil (S. album): Priced at about US$2,500 per kilogram (US$5,512 per lb), primarily due to its higher alpha-santalol content, which contributes to its superior fragrance profile.

Socio-Environmental Impact

Sandalwood has played a significant role in the political economy of the Pacific, serving as a marker of status and a crucial trade commodity during the colonial period. However, this commercialization often led to unsustainable practices. In Tonga, for instance, the traditional kinship-based social system (fahu) that regulated 'ahi (sandalwood) harvest was disrupted. As sandalwood became a valuable market commodity, lower-ranking family members began harvesting without permission, prompting defensive harvesting by many farmers, which ultimately led to severe overharvesting and depletion of nearly all sandalwood resources within two years. This highlights the complex interplay between resource commodification, land tenure, and ecological fragmentation.

Diverse Applications

Fragrance & Perfumery

Sandalwood oil is renowned for its distinctive soft, warm, smooth, creamy, and milky precious-wood scent. Its quality and aromatic profile are significantly influenced by the tree's age, geographical location, and the distiller's expertise. In perfumery, it provides a long-lasting, woody base for oriental, woody, fougรจre, and chypre fragrance families. When used in smaller proportions, it acts as a fixative, extending the longevity of more volatile components. It is also a key ingredient in "floriental" fragrances, blending harmoniously with white florals like jasmine, ylang-ylang, and gardenia, and complements other woody scents such as patchouli and cedar.

  • Cosmetic Industry: Sandalwood oil is extensively used in the Indian cosmetic industry.
  • Supply Challenges: Due to S. album being a protected species, demand often outstrips supply, leading to the trade of oils from closely related species or even unrelated plants like West Indian sandalwood (Amyris balsamifera) or bastard sandalwood (Myoporum sandwicense). However, these alternatives typically lose their aroma much faster.
  • Synthetic Alternatives: Isobornyl cyclohexanol is a synthetic fragrance chemical developed as an alternative to natural sandalwood oil.
  • Key Components: The main aromatic components of sandalwood are the two isomers of santalol, which constitute about 75% of the oil.
  • Other Uses: Beyond fine perfumes, sandalwood oil is utilized in aromatherapy, scented candles, and soap production.

Idols & Sculptures

The fine grain and workability of sandalwood make it an excellent medium for carving. Traditionally, it has been a preferred wood for creating intricate statues and sculptures of Hindu deities, embodying both artistic expression and spiritual reverence.

Technological Applications

Sandalwood oil possesses unique optical properties, specifically low fluorescence and an optimal refractive index. These characteristics make it a valuable immersion oil in advanced microscopy techniques, particularly in ultraviolet and fluorescence microscopy, where it aids in enhancing image clarity and resolution.

Culinary Uses

Sandalwood, in various forms, has found its way into culinary traditions across different cultures.

  • Aboriginal Australia: Indigenous Australians traditionally consume the seed kernels, nuts, and fruit of local sandalwoods, such as the quandong (Santalum acuminatum).
  • Early European Settlers in Australia: Used quandong in cooking damper by infusing it with leaves, and prepared jams, pies, and chutneys from its fruit.
  • Scandinavia: Pulverized bark from red sandalwood (Pterocarpus soyauxii), an unrelated species, is used with other tropical spices to marinate anchovies and certain types of pickled herring (e.g., matjes, sprat, traditional spegesild), imparting a reddish color and a subtly perfumed flavor.
  • Modern Gastronomy: Contemporary chefs are experimenting with sandalwood nuts as a substitute for macadamia nuts or as a "bush food" alternative to almonds and hazelnuts in Southeast Asian-inspired cuisine.
  • Flavoring Agent: Sandalwood oil is also employed as a flavor component in a variety of food items, including candies, ice cream, baked goods, puddings, alcoholic and non-alcoholic beverages, and gelatin. Its use is typically at very low concentrations, below 10 ppm, with a maximum permissible level of 90 ppm in food products.

Oil Distillation

Extraction Methods

The extraction of essential oil from sandalwood employs several methods, each with distinct characteristics. These include steam distillation, water distillation, CO2 extraction, and various solvent extractions. Among these, steam distillation is the most prevalent method utilized by commercial sandalwood producers, favored for its efficiency and quality output.

The Steam Distillation Process

Steam distillation is a meticulous four-step process: boiling, steaming, condensation, and separation. Water is heated to high temperatures (60โ€“100 ยฐC or 140โ€“212 ยฐF), and the resulting steam is passed through the sandalwood. The high heat of the steam effectively releases the oil, which is tightly bound within the wood's cellular structure. The mixture of steam and oil is then cooled, allowing the essential oil to separate and be collected. This process is notably longer than for most other essential oils, typically requiring 14 to 36 hours to complete, but it generally yields a superior quality oil.

Traditional Water Distillation

Water, or hydro, distillation represents a more traditional approach to sandalwood oil extraction. This method involves soaking the wood in water and then boiling the mixture until the oil is released. While historically significant, this technique is less commonly used today due to the substantial costs and time associated with heating large volumes of water, making it less commercially viable compared to modern steam distillation.

Spiritual Significance

Hinduism

In Hinduism, sandalwood, known as chandana in Sanskrit, holds profound sacred significance within Ayurvedic traditions. It is believed that Lakshmi (Sri), the goddess of well-being, resides in the sandalwood tree, hence its alternative name, Srigandha. Sandalwood paste, prepared by grinding dry sandalwood with water, is central to rituals. This paste, called kalabham in Malayalam and gandha in Kannada, is often mixed with saffron or other pigments to create chandanam. Further blending with herbs and perfumes yields javadhu. These pastes and their dried powder forms are widely used in India and Nepal.

  • Sacred Application: In Tirupati, sandalwood paste is applied to the skin after religious tonsure for protection.
  • Divine Connection: In Hindu and Vedic societies, sandalwood is thought to facilitate a closer connection to the divine, making it a highly revered element.
  • Ceremonial Use: The paste is integral to various rituals and ceremonies, used for crafting religious utensils, adorning sacred images, and is believed to induce mental tranquility during meditation and prayer.
  • Devotional Practice: It is also distributed to devotees, who apply it to their foreheads, necks, or chests as a mark of spiritual devotion. Sandalwood paste is a staple for most pujas in both temples and private homes.

Jainism & Buddhism

Sandalwood plays an integral role in the daily practices of Jainism and holds significant mention in Buddhist traditions.

Jainism

  • Worship: Sandalwood paste, often mixed with saffron, is used in the worship of the Tirthankaras.
  • Blessings: Jain monks and nuns (sadhus and sadhvis) shower sandalwood powder as blessings upon their disciples and followers.
  • Cremation: Sandalwood garlands are used to adorn the body during Jain cremation ceremonies.
  • Mahamastakabhisheka: During this festival, held every 12 years, the Gommateshwara statue is ritually bathed and anointed with various libations, including sandalwood paste, and sprinkled with sandalwood powder.

Buddhism

  • Pฤli Canon: Sandalwood is referenced in several suttas of the Pฤli Canon.
  • Symbolism: In some Buddhist traditions, sandalwood is associated with the padma (lotus) group and attributed to Amitabha Buddha.
  • Meditation Aid: Its scent is believed to aid in transforming desires and maintaining alertness during meditation.
  • Offerings: It is one of the most popular scents used when offering incense to the Buddha and spiritual gurus.

Sufism & East Asian Religions

Sandalwood's spiritual resonance extends to Sufism and various East Asian religious practices, underscoring its widespread cultural and devotional importance.

Sufism

  • Devotional Mark: In Indian variants of Sufism, disciples apply sandalwood paste to the graves of revered Sufi saints as a profound mark of devotion. This tradition is particularly observed by devotees in the Indian Subcontinent.
  • Tamil Culture: In Tamil culture, regardless of religious identity, sandalwood paste or powder is applied to Sufi saints' graves as a gesture of devotion and respect.

East Asian Religions

  • Incense: In East Asia, sandalwood (ๆช€ๆœจ) is the most commonly used incense material by Chinese, Korean, and Japanese practitioners in worship and various ceremonies.
  • Taoist Exceptions: Some Taoist sects, adhering to the Ming Dynasty Taoist Manual, refrain from using sandalwood (along with benzoin resin and frankincense) as incense in worship.
  • Korean Shamanism: In Korean Shamanism, sandalwood is revered as the "Tree of Life."
  • Buddhist Transmission: Its use was transmitted to China, the Korean Peninsula, and Japan during the eastward expansion of Buddhism.

Zoroastrianism

Zoroastrians incorporate sandalwood into their religious ceremonies, particularly in fire temples. They offer sandalwood twigs to the afarganyu, the urn where the sacred fire is maintained in the fire temple (known as agiyari in Gujarati and dar-e mehr in Persian), to sustain the eternal flame during religious rites. After the firekeeping priests conclude the ceremony, attendees are permitted to place their own pieces of sandalwood into the fire.

  • Sacred Fire: Fire is a sacred symbol in Zoroastrianism, and maintaining constantly burning fires in temples is of paramount importance. Sandalwood, due to its high sensitivity to fire, serves this purpose exceptionally well.
  • Scriptural Endorsement: The sacred texts, Yasna and Yashts, accept sandalwood as an appropriate fuel for the holy fire.
  • Grades of Fire: It is offered to all three grades of fire within the fire temple, including the Atash Dadgahs. However, sandalwood is not offered to the divo, a smaller lamp kept in Zoroastrian homes.
  • Offerings: Often, money is offered to the mobad (priest) alongside sandalwood. Sandalwood is referred to as sukhad within the Zoroastrian community. It is sometimes more expensive to purchase at a fire temple than at a Zoroastrian store, serving as a revenue source for the temple.
