Printed from smellbook.com/smells/eucalyptus. This printout keeps the entry for Eucalyptus itself: its description, reference card, Connections, questions, evidence, related smells, record details, states, names and citation. It leaves out your own notes, the map, the lists of paths, routes, stories and fragrance directions, and the lists headed “Also linked to” (other entries that share its place or material) and “Linked from”; they are on the page online. The entries this one links to are still printed under Connections and Related smells.

A sharp aromatic-green smell direction often perceived as cool, penetrating and clean.
Its type, Source, means the smell is named after “a physical origin that can contribute a smell”; it is not an evidence source, such as a study or a book. The origin page for Eucalyptus (the plant, not this smell entry) lists every smell recorded as coming from it.
Eucalyptus smells sharp, cool and green, with a penetrating, clean aromatic edge and a broad, airy feel in the nose. EDITORIAL
Named in the VERIFIED claims about this smell: not a list of what it is made of, and not its cause.
Links SmellBook records for this entry: what it comes from, where you meet it, what was written about it, molecules, related smells and comparisons. EDITORIAL links are chosen by SmellBook editors, VERIFIED links come from VERIFIED claims and HISTORICAL links describe what one source wrote at one time. Nothing here is a ranking, and a molecule is not presented as the cause of the smell.
QUESTIONS ABOUT EUCALYPTUS
Eucalyptus smells sharp, cool and green, with a penetrating, clean aromatic edge and a broad, airy feel in the nose. Crushed leaves are intense and almost stinging; dried branches are softer, drier and more woody. The smell is strong and persistent. It is easily confused with mint or rosemary, though eucalyptus feels more piercing and less sweet.
People meet it in gardens and parks where the trees grow, in dried leaves used in bouquets and wreaths, and in home fragrance, steam rooms and bath products. Many people link it with cleanliness and fresh air.
Typical settings: eucalyptus leaves, garden, home-fragrance association.
SmellBook links it to 2 place pages: see them in Connections.
One VERIFIED scientific claim from one published source is recorded for this entry: 1,8-Cineole in eucalyptus oils. This claim says only what its source supports, in the scope shown with it.
The scientific study behind this evidence is chemistry or emission work, not a study of how the smell is perceived.
It also has one historical source, which records what was written without stating the time described, not a scientific finding: see its historical records.
One molecule is named in this claim; see the evidence for the role the claim gives it. The molecule this claim names has only the role the claim states.
Eucalyptus is presented as a sensory source profile, not as a health or therapeutic claim.
SmellBook records 2 written comparisons with other smells: see them in Connections.
Words that are easy to mix up: How do green and herbal differ?
One historical source describes it. It describes a time it does not state, no later than its publication, not the present: see its date in Connections; the sources are with the evidence below.
Answers marked EDITORIAL are written by SmellBook editors to describe the experience and add no scientific fact. Answers marked VERIFIED point to claims on published sources, checked against each source's own summary where one was available (each claim's page says how); what each claim supports is in its own text and scope.

Chemistry reported
1,8-Cineole in eucalyptus oils
In leaf essential oils of several Western Australian eucalyptus species, 1,8-cineole was the main component at about 67 to 97%, and it made up 77% of a commercial Eucalyptus globulus oil.
Oils distilled from the leaves of selected species; composition varies by species and chemotype.
How this was found: Chemical composition. Compounds were identified or measured, without any assessment of their odour. Source: primary study; chemistry work.

Eucalyptus groves described in an 1874 publication
In an 1874 publication, Robert Bentley describes the foliage of eucalyptus groves as giving the surrounding air an odour he calls agreeable, aromatic, camphoraceous and stimulating.
A botanist's description published in 1874, set within the miasma theory of fever, which SmellBook does not endorse; it is not a measurement of eucalyptus odour.
How this was found: Historical text. A published historical text, read on a digitised page; it records what was written when it was published. Source: historical record.
Passage: p. 9. Published 1874, the latest time it can describe; not the present.

PATHS FROM HERE
Each step is a relationship SmellBook editors recorded in the knowledge graph, named as it is published there. Paths are not ranked or personalised, and they do not mean the smells smell alike.
Each step is a molecule that a VERIFIED claim names for both smells, in whatever role the claims state. Sharing a molecule does not mean two smells smell alike.
