Oud, Oudh, and Agarwood: One Material, Three Names Explained

The terms oud, oudh, and agarwood appear constantly across fragrance retail, review sites, and brand marketing — often used interchangeably, sometimes used as if they describe different materials. They do not. All three refer to the same source: the dark, resin-saturated heartwood of Aquilaria trees, principally Aquilaria malaccensis, Aquilaria crassna, and Aquilaria sinensis. The difference between the names is linguistic and contextual, not material.

This is the practical breakdown for buyers.

The etymology: oud and oudh are the same Arabic word

"Oud" and "oudh" are two Romanizations of the same Arabic word, عود (literally "wood" or "stick"). Both spellings appear in published fragrance literature; "oud" is the more common Western transliteration, "oudh" is more common in South Asian English and on bottles produced for Gulf markets. There is no chemical, botanical, or grade difference implied by the spelling — a bottle labeled "Lattafa Bade'e Al Oud" and a bottle labeled "Bade'e Al Oudh" are referring to the same raw material category.

"Agarwood" is the English botanical and trade term for the wood itself, used in CITES regulations, in scientific literature, and in the timber and incense trades. When you see "agarwood" on a perfumery ingredient label, it indicates the same resinous Aquilaria heartwood that "oud" and "oudh" refer to — typically in the form of wood chips for distillation or as the source of the distilled oud oil.

The biology: oud forms only when Aquilaria trees are wounded

Healthy Aquilaria heartwood is pale and unscented. The dark, fragrant resin that defines oud forms only when the tree responds to infection — most commonly by the mold Phialophora parasitica or related fungi colonizing a wound in the trunk. The tree produces a dense, aromatic resin called aloes as a defense response. Over years to decades, this resin saturates the surrounding heartwood, transforming it from a soft, light timber into a dense, dark, intensely fragrant material.

This biological prerequisite — infection of a wounded tree, followed by years of resin accumulation — is the reason real oud is among the most expensive raw materials in perfumery. Wild infected Aquilaria are rare; the species is CITES-listed as endangered for A. malaccensis due to overharvesting. Modern oud production increasingly relies on artificially inoculated plantation trees in Cambodia, Vietnam, Thailand, Indonesia, Malaysia, and Assam (India), where Aquilaria are deliberately wounded and inoculated with fungal cultures to accelerate resin formation.

Price: real distilled oud oil ranges from $30,000 to $80,000+ per kilogram

Distilled oud oil at perfumery grade trades in a wide range depending on origin, grade, and age. Mid-grade Cambodian or Thai oud oil typically prices at USD $30,000-$50,000 per kilogram at wholesale. Top-grade Hindi (Indian Assam) oud, prized for its animalic, barnyard-style profile, can exceed USD $80,000 per kilogram. Aged ouds — distilled oil aged for years or decades — command further premiums and are typically sold in single-tola quantities rather than by the kilogram.

For comparison, rose absolute trades at roughly $5,000-$10,000 per kilogram and natural jasmine absolute at $4,000-$8,000 per kilogram. Oud is several times more expensive than the most luxurious florals in perfumery.

Why most "oud" fragrances do not contain meaningful real oud

Given the price of distilled oud oil, the vast majority of fragrances marketed as "oud" — including many high-end designer releases — contain either no real oud, or only trace amounts blended with synthetic oud-reconstruction accords. The dominant synthetic oud bases in modern perfumery include Firmenich's Oud Synthetic, IFF captives like Oud Wood, and Givaudan's Oud Cypriol accords. These are designed to capture the smoky, resinous, animalic profile of real oud at a fraction of the cost.

A few practical signals that a fragrance contains real oud rather than only synthetic reconstruction:

• The retail price is at minimum USD $200-$300 for a 50mL bottle (because real oud at any meaningful concentration prices the formulation accordingly)
• The brand discloses the oud origin (Cambodi, Hindi, Trat, Aceh) rather than describing the note simply as "oud"
• The drydown develops over hours, gaining complexity and animalic depth, rather than fading or staying linear in the way many synthetic oud accords do
• The fragrance is sold by a house with traditional Middle Eastern attar lineage rather than a designer house using oud as a marketing accent

Regional style differences: Middle Eastern oud versus Western oud

Middle Eastern perfumery traditionally uses oud at high concentrations — sometimes as the dominant or sole note — in compositions like mukhallat (oil blends) and dahn al oud (pure oud oil for direct skin application). These are typically oil-based, very long-lasting, and centered on the woody-resinous-animalic character of the raw material.

Western designer perfumery typically uses oud as one note among many in an alcohol-based EDP composition, blended with rose, saffron, leather, or amber notes to create a softened, more accessible interpretation of the material. Tom Ford's Oud Wood, YSL's M7, and Maison Francis Kurkdjian's Oud Satin Mood are examples of the Western interpretation — oud as a structural element, not the centerpiece.

The same word, oud or oudh, can therefore describe radically different sensory experiences depending on whether the bottle was composed in the Khaleeji (Gulf) tradition or the Western designer tradition.
