Sandalwood Essential Oil: Types, Uses, Sustainability and Safety

Quick answer: true sandalwood essential oil is steam distilled from the heartwood and roots of Santalum trees, mainly East Indian sandalwood (Santalum album) and Australian sandalwood (Santalum spicatum). Its soft, creamy, woody scent comes largely from compounds called santalols. Santalum album is listed as Vulnerable on the IUCN Red List, so buy from suppliers who can document legal, sustainable sourcing. Sandalwood is considered one of the gentler essential oils, but it should still be diluted, kept away from children and pets and never swallowed. “West Indian sandalwood” is a different plant, amyris, and is not a true sandalwood.

Few scents are as recognizable as sandalwood. It is soft, warm and milky rather than sharp, and it lingers on skin and fabric for hours. That staying power has made it one of the most valued materials in perfumery for centuries, and it is also a favorite in calming home blends.

Sandalwood is also one of the most expensive and most frequently faked oils on the market. Understanding where it comes from, which species you are buying and how it should be used helps you avoid paying a premium for a bottle that is not what it claims.

What Sandalwood Is

Sandalwood is the name for several slow-growing trees in the genus Santalum, part of the sandalwood family (Santalaceae). Kew’s Plants of the World Online lists more than a dozen species spread across South and Southeast Asia, Australia and islands of the Pacific, including Hawaii.

These trees have an unusual way of living. Santalum species are hemiparasites: they make their own food through photosynthesis, but their roots also attach to the roots of neighboring plants to draw water and nutrients. Growers have to plant host species alongside young sandalwood trees, which is one reason plantations take careful planning.

The prized fragrance is concentrated in the heartwood, the dense inner wood at the center of the trunk, and in the larger roots. Heartwood develops slowly. A young tree may contain very little of it, which is why mature trees have always been valuable and why wild stands have been heavily harvested.

The oil itself

Sandalwood essential oil is produced mainly by steam or water distillation of chipped or powdered heartwood. The oil is thick, pale yellow and slow to evaporate. Its scent is often described as:

• Soft, creamy and woody
• Slightly sweet, sometimes described as milky or buttery
• Gentle rather than sharp, with very little top note
• Long lasting, especially on skin and fabric

Because it evaporates so slowly, perfumers treat sandalwood as a base note and a fixative. It holds lighter, more volatile ingredients in a blend and helps the whole fragrance last longer.

The Main Types of Sandalwood Oil

Not every bottle labeled “sandalwood” comes from the same tree. The botanical name on the label matters more than the common name.

Label name	Botanical name	Origin	Notes
East Indian or Mysore sandalwood	Santalum album	India, Sri Lanka, Indonesia; plantations in northern Australia	The classic perfumery sandalwood; highest santalol content; most expensive
Australian sandalwood	Santalum spicatum	Western Australia	Drier, slightly sharper scent; lower santalol content; widely available
Hawaiian sandalwood	Santalum paniculatum and related species	Hawaii	Small, specialized production
New Caledonian or Pacific sandalwood	Santalum austrocaledonicum	New Caledonia and Vanuatu	Smaller supply, close in character to S. album
“West Indian sandalwood” (amyris)	Amyris balsamifera	Caribbean and northern South America	Not a true sandalwood; different plant family (Rutaceae)

East Indian sandalwood

Santalum album is the sandalwood of classical perfumery and of religious and cultural traditions across South Asia. Its oil is the reference material for ISO 3518, the international standard that sets quality ranges for this oil, including acceptable levels of its two main constituents, alpha-santalol and beta-santalol.

Indian sandalwood from the Mysore region of Karnataka built a worldwide reputation, and Indian states have historically controlled harvesting and sale of the wood closely. Today, a significant share of commercial Santalum album also comes from plantations established outside India, including in northern Australia.

Australian sandalwood

Santalum spicatum grows in the dry woodlands of Western Australia and has been traded for well over a century. Its oil has its own international standard, ISO 22769. It generally contains less santalol than East Indian oil and has a slightly drier, more resinous scent. Many aromatherapy brands now sell it as a more affordable and more traceable option.

Amyris, the “sandalwood” that is not

Amyris balsamifera is sometimes sold as “West Indian sandalwood,” but it belongs to the citrus family, not the sandalwood family. Its oil is woody and mild and can make a reasonable budget substitute in blends, but it does not smell the same and does not have the same chemistry. We cover it separately in our overview of amyris balsamifera oil.

Why Sustainability Matters

Sandalwood has a long history of overharvesting. Because the most valuable part of the tree is the heartwood, and because roots are distilled too, harvesting a wild tree usually means removing the whole tree.

The IUCN Red List of Threatened Species lists Santalum album as Vulnerable, reflecting declines in wild populations driven by overexploitation, illegal felling and disease. Several Pacific species have also been depleted by centuries of trade. In Hawaii, the sandalwood trade of the early 1800s stripped large areas of native forest.

What this means for buyers:

• Ask where the wood came from. Reputable suppliers can say whether oil comes from licensed plantations, government auctions or managed wild harvest.
• Expect a high price for real Santalum album. Very cheap “Indian sandalwood” is a warning sign of dilution or substitution.
• Consider Australian sandalwood. Santalum spicatum is harvested under a state management system in Western Australia and is widely sold with clear origin information.
• Use less. Because sandalwood is potent and long lasting, a small amount goes a long way in blends.

What People Use Sandalwood Oil For

Most uses of sandalwood are about its scent. Health claims made for it online often go far beyond what research supports.

Perfumery

Sandalwood is a base note in countless perfumes, especially woody, oriental and floral blends. It rounds off sharper notes, adds warmth and helps a scent last. Natural sandalwood oil is so expensive that many commercial fragrances rely partly or fully on synthetic sandalwood aroma molecules, which are designed to reproduce its creamy, woody character.

Attars

In Kannauj, a city in the Indian state of Uttar Pradesh long known for perfume, artisans make traditional attars by distilling flowers such as rose or jasmine and collecting the fragrant vapor in a vessel containing sandalwood oil. The sandalwood acts as the base that captures and holds the floral scent. This is one of the oldest continuous uses of the oil.

Religious and cultural use

Sandalwood paste, powder and incense are part of religious practice in Hinduism, Buddhism and Jainism, among other traditions. These uses are cultural and spiritual, and they help explain why demand for the wood has been so high for so long.

Aromatherapy blends

At home, sandalwood is most often used in diffuser and massage blends intended to feel calming or grounding, and in meditation routines. That fits its scent profile. The NCCIH notes that research on aromatherapy in general is limited and that results for specific conditions are mixed, so treat these uses as a matter of preference and atmosphere rather than treatment. If you are building an evening routine, our guide to essential oils for sleep explains what the research does and does not show.

Skin and hair products

Sandalwood oil appears in soaps, lotions, beard oils and hair products, mostly for fragrance. Cosmetic manufacturers in the European Union and other markets follow specific labeling and concentration rules for fragrance ingredients.

What the Research Says

There is real scientific interest in sandalwood, but much of it is early-stage laboratory work.

• Alpha-santalol has been studied in cell cultures and animal models for possible effects on skin cells and inflammation. These studies are not evidence that rubbing sandalwood oil on your skin will treat a condition.
• Olfactory receptors in skin. A 2014 study by Busse and colleagues in the Journal of Investigative Dermatology found that a synthetic sandalwood odorant, Sandalore, activated an olfactory receptor (OR2AT4) found in human skin cells and promoted wound-healing-related processes in the lab. That result involved a synthetic molecule, not natural sandalwood oil, and was done in cell cultures.
• Mood and relaxation. Small studies have tested inhaled sandalwood or its constituents for effects on alertness and relaxation, with mixed findings.

The honest summary: sandalwood smells lovely and is generally well tolerated, but it is not a proven treatment for anything. Be skeptical of products that claim otherwise.

Safety: Gentle, but Not Risk-Free

In Essential Oil Safety, Tisserand and Young describe sandalwood oils as relatively low risk compared with many other essential oils. That does not mean they can be used carelessly.

Skin reactions

Sandalwood can cause allergic contact dermatitis in a small number of people. The risk rises with high concentrations, frequent repeated use and old, oxidized oil. Always dilute it in a carrier oil and patch test before wider use. Our guide to essential oil skin reactions explains how to tell irritation from allergy and what to do if your skin reacts.

General rules

• Dilute it. For adult body use, low dilutions of around 1 to 2 percent are a common starting point. Our essential oil dilution chart shows how many drops that means in practice.
• Do not swallow it. Essential oils are concentrated and can cause harm if ingested.
• Keep it away from eyes and mucous membranes.
• Children. Use extra caution and lower dilutions, and keep bottles out of reach.
• Pregnancy and breastfeeding. Ask a qualified healthcare provider before using any essential oil.
• Pets. Cats in particular are sensitive to essential oils. Diffuse only briefly in well-ventilated rooms and make sure pets can leave.

If you have a skin condition, take medication or have a chronic health problem, talk to a healthcare professional before using sandalwood or any other essential oil regularly.

How to Use Sandalwood at Home

Sandalwood’s strength is that it blends well and lasts. A few simple ways to use it:

1. Diffuser blend. Add a few drops to a diffuser with water according to the manufacturer’s instructions. Run it for short periods, such as 30 to 60 minutes, with breaks, in a ventilated room.
2. Body oil. Mix a small amount into a carrier oil such as jojoba or sweet almond at a low dilution for a simple massage oil.
3. Personal fragrance. Combine sandalwood with a floral or citrus oil in a carrier oil to make a solid base for a homemade roll-on.
4. Linen or room scent. Because it is so persistent, sandalwood works well as the base of a fabric or room spray. Test on an inconspicuous spot first, since oils can stain.

Oils that blend well with sandalwood

Sandalwood pairs with almost anything, which is why perfumers rely on it. Common pairings include:

• Rose and jasmine for a rich floral blend
• Bergamot or sweet orange to brighten its softness
• Frankincense for a resinous, meditative blend
• Lavender for a gentle evening blend
• Vetiver or cedarwood for a deep, earthy blend
• Ylang ylang for a sweet, exotic floral note

Buying Real Sandalwood Oil

Because genuine Santalum album oil is so expensive, it is a frequent target for adulteration. Oils may be cut with cheaper carrier oils, blended with amyris or other woods, or reinforced with synthetic aroma chemicals.

A trustworthy bottle should come with:

• The full botanical name (Santalum album, Santalum spicatum or another named species)
• Country of origin and, ideally, whether the wood is plantation or wild-harvested
• Plant part (heartwood, sometimes with roots)
• Extraction method (usually steam distillation)
• A batch-specific GC/MS report showing the main constituents, including the santalols
• A price that makes sense for the species named

If a label just says “sandalwood fragrance” or “sandalwood oil blend,” it is probably not pure essential oil. For a full checklist, see our guide on how to tell if essential oils are pure.

“Sandalwood” diluted in jojoba

Some brands sell sandalwood pre-diluted in jojoba, often labeled as a percentage such as 5 or 10 percent. This can be a sensible, affordable way to buy an expensive oil, as long as the label states the dilution clearly. Just do not compare its price directly with a pure, undiluted oil.

Storage and Shelf Life

Sandalwood is one of the more stable essential oils. Its heavy, slow-evaporating compounds oxidize more slowly than those in citrus or pine oils, and many people find that a well-stored bottle keeps its quality for several years. Some perfumers believe the scent becomes richer with age.

Good storage still matters:

• Keep the bottle tightly capped, in dark glass, away from heat and direct sunlight.
• Move oil to a smaller bottle as you use it so less air sits in the bottle.
• Discard oil that smells sour, harsh or very different from when you bought it.

Frequently Asked Questions

What does sandalwood essential oil smell like?

It has a soft, creamy, woody scent with a slightly sweet, milky quality. It has very little sharp top note and lasts a long time, which is why perfumers use it as a base note.

What is the difference between Indian and Australian sandalwood oil?

Indian sandalwood comes from Santalum album and usually has a higher santalol content and a richer, creamier scent. Australian sandalwood comes from Santalum spicatum, has a drier, slightly sharper scent and is generally more affordable.

Is sandalwood essential oil endangered?

Santalum album, the East Indian species, is listed as Vulnerable on the IUCN Red List because wild populations have declined. Look for oil from documented plantations or managed harvests.

Is West Indian sandalwood real sandalwood?

No. West Indian sandalwood is amyris (Amyris balsamifera), a tree in the citrus family. Its oil is woody and mild but chemically and botanically different from true sandalwood.

Can I put sandalwood oil directly on my skin?

It is best to dilute it in a carrier oil and patch test first. Although sandalwood is considered relatively gentle, it can still cause allergic reactions in some people.

Is sandalwood oil safe to diffuse around pets?

Use caution. Cats are especially sensitive to essential oils. Diffuse briefly in a ventilated room and make sure pets can leave the area.
