Labdanum

What it is

Labdanum is the highly aromatic resin associated especially with Cistus ladanifer, the gum rockrose. The plant is native to the western Mediterranean region, and the resin has a long history in fragrance.

It should be distinguished from the plant’s essential oil: labdanum resin, cistus essential oil and the various extracts made from them are related but not identical aromatic materials.

How it appears in perfumery

Labdanum can be encountered as:

• raw or processed resin
• labdanum gum
• resinoid
• absolute
• related cistus oil materials

Extraction method changes the balance of volatile and less-volatile constituents, so different labdanum products can smell noticeably different.

What to notice

Typical directions include warm resin, leather, balsamic sweetness, dry wood, smoke and ambery depth. Some extracts lean darker and more leathery; others feel sweeter, softer or more herbal.

Labdanum often supplies the darker resinous backbone of an amber accord.

Labdanum, amber and ambergris

These terms are easy to blur:

• Labdanum is a plant resin.
• Amber in perfumery is usually an accord or style.
• Ambergris is an animal-derived material associated with sperm whales.

Labdanum is one of the classic materials used to build amber-style effects, but that does not make it ambergris.

Keep forms distinct

When possible, this notebook should preserve whether a source refers to labdanum resin, absolute, resinoid, cistus oil or simply an amber-style note rather than flattening all of them into “labdanum.”
