Oud is the dark, resin-soaked heartwood of the Aquilaria tree, which forms only after the tree is wounded or infected by a fungus. In India it is called agar, and in English, agarwood. Distilled into oil or blended into perfume, it gives a deep, woody, smoky scent that stays on skin for hours.
If you have seen oud, oudh or aoud on a perfume label and wondered what it means, this guide explains where oud comes from, what it smells like, the main types, why real oud is so expensive, and how to start wearing it.
What Is Oud? The Meaning Behind the Name
The word oud comes from Arabic, where it means wood. You will see it spelled several ways: oud, oudh, oude and aoud. All of them refer to the same material.
Oud goes by many names depending on the language:
| Language or region | Name |
|---|---|
| Hindi and Urdu | Agar |
| Sanskrit | Aguru |
| Bengali, Telugu, Kannada | Aguru |
| Assamese | Xasi or sashi |
| English | Agarwood, aloeswood |
| Indonesian | Gaharu |
| Japanese | Jinko |
When a bottle is labelled "oud perfume", it means oud, or an accord built to smell like oud, is one of the main notes. It usually sits in the base of the fragrance.
Where Does Oud Come From?
Oud comes from trees of the Aquilaria genus. There are around fifteen species, and the main ones used for oud are Aquilaria malaccensis, Aquilaria crassna and Aquilaria sinensis.
A healthy Aquilaria tree produces pale wood with almost no smell. Oud forms only when the tree is damaged by insects, fungi, lightning or deliberate cuts. To defend itself, the tree produces a dark, fragrant resin inside its heartwood. Over years, sometimes decades, this resin spreads through the wood and turns it dark brown or black. That resin-rich wood is oud.
How Is Oud Made?
Once harvested, the resin-rich parts of the wood are carved out by hand, a process that can take hours. Oud is then used in two main ways:
- As oil: The wood is distilled, usually with steam, to extract oud oil. This oil is the base for oud attars and perfumes.
- As wood chips: Small pieces are burned as incense, a practice common in Middle Eastern homes and places of worship.
Oud and India
India has one of the world's important agarwood reserves. Aquilaria malaccensis grows naturally in the north-eastern states of Assam, Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura and Meghalaya.
Agar also has a long history in Indian culture:
- It is listed first among the ashtagandha, the eight traditional fragrant materials.
- It is referenced in Ayurvedic texts, including the Charaka Samhita.
- It appears in the poetry of Kalidasa.
What Does Oud Smell Like?
Oud's scent comes from two groups of natural compounds in the resin. Chromones give it a warm, leathery, smoky character. Sesquiterpenes add an animalic, slightly fermented edge.
People commonly describe real oud as smelling of:
- Damp wood and wet earth
- Smoke and incense
- Leather
- Honey, when warmed on skin
- A faint barnyard or animalic note
On its own, oud is not sweet, floral or fresh. First-time wearers often find the opening strong. It softens as it settles on skin.
Synthetic oud smells different. It tends to be less animalic, sweeter and nuttier than natural oud, which is why many modern oud perfumes feel smoother than pure oud oil.
Perfumers rarely use oud alone. The most common pairings are:
- Rose, which softens oud's animalic edge
- Saffron, which adds a dry, suede-like quality
- Leather, which makes the blend heavier and richer
- Amber, which warms oud into something sweeter
Types of Oud by Origin
Oud smells different depending on where the tree grew, the species, the soil and how long the resin developed. The main origins you will see referenced are:
| Origin | Scent character |
|---|---|
| Indian (Assam, also called Hindi oud) | Deep, animalic, dry, with a medicinal edge |
| Cambodian | Sweet, balsamic, honeyed |
| Malaysian | Softer and rounder |
| Thai | Dry and leathery |
Oud is also classed as wild or cultivated. Wild oud comes from naturally infected forest trees and is rarer. Cultivated oud comes from plantation trees, which now supply much of the commercial market.
Names like "Oud Hindi" or "White Oud" on a bottle are usually product names that describe a style. They do not certify where the oud came from, so read the notes list to understand what you are buying.
Oud Oil, Oud Attar and Oud Perfume: What's the Difference?
Oud reaches you in several forms, and each wears differently.
| Format | What it is | How it wears |
|---|---|---|
| Oud oil (Dehn Al Oud) | Pure distilled oud oil | Most intense and most expensive; a tiny amount is enough |
| Oud attar | Oil-based, alcohol-free blend with oud as a key note | Applied as a dab; stays close to skin and lasts long |
| Oud perfume | Alcohol-based spray with oud or an oud accord in the base | Projects more; easier for beginners |
| Bakhoor | Wood chips blended with other ingredients | Burned to scent rooms and clothes |
If you are unsure between the two most common formats, read our guide on the difference between attar and perfume. To browse oil-based options, see the attar perfume collection. If you are curious about burning oud at home, our post on the benefits of burning bakhoor covers how bakhoor is used.
Real Oud vs Synthetic Oud
Most oud perfumes sold at everyday prices do not contain large amounts of real oud oil. Commercial-grade pure oud oil costs between USD 30,000 and USD 100,000 per kilogram, so a regular retail bottle cannot hold much of it.
Instead, most oud perfumes use an oud accord. This is a blend of aroma compounds designed to recreate oud's woody, smoky direction. This is standard practice in perfumery and not a trick. Many well-loved oud fragrances are built on accords.
A few signs help you judge what you are buying:
- Price per ml. Pure oud oil is sold in grams or small vials at high prices, not in 100 ml sprays at everyday rates.
- How it behaves on skin. Natural oud tends to smell more animalic and changes noticeably over several hours. Accords usually smell cleaner and more consistent from start to finish.
- Ingredient clarity. Brands that use real oud usually say so specifically.

Why Is Oud So Expensive?
Several factors push up the price of real oud:
- Few trees produce it. Only a small share of wild Aquilaria trees, commonly estimated at about one in ten, develop the resin naturally.
- It takes years. The resin needs years, and for the finest grades decades, to saturate the wood.
- The yield is low. Around 10 kg of resin-rich wood produces only about 20 ml of pure oud oil.
- The work is manual. The resin-rich wood is carved out by hand before distillation.
- Supply is restricted. Wild Aquilaria is protected under CITES, which limits how much wild agarwood can be traded.
Is Oud for Men or Women?
Oud is not tied to any gender. In the Middle East it has been worn by men and women for centuries, and modern perfumers use it in fragrances for both.
What changes is the pairing:
- Rose-oud and amber-oud blends read softer and are popular in women's fragrances. Browse perfume for women or explore oil-based options in attar for women.
- Leather, spice and smoky oud blends read heavier and are common in perfume for men.
The best approach is to pick by scent profile rather than by label.
How to Wear Oud as a Beginner
Oud is strong, so a little technique helps.
- Start blended, not pure. Begin with an oud perfume or an oud attar rather than pure oud oil. Blends are easier to wear and help you learn the note.
- Use less than you think. One or two sprays, or a single dab of attar on the wrists and neck, is usually enough. Our guide on how to apply attar covers the right spots.
- Wait 30 minutes before judging. The opening is the sharpest part. The drydown is where oud turns warm and smooth.
- Match it to the weather. Heavy, oud-forward scents suit evenings and cooler months. In Indian summer heat, lighter oud blends or fewer sprays work better, because heat makes strong scents feel heavier.
- Store it well. Scents with rich base notes like oud are less sensitive to oxidation than lighter fragrances, but heat and light still damage them. See how to store perfume correctly.
