Fragrant Wood: 12 Aromatic Species by Scent, Hardness & Safety
Fragrant wood gets its smell from oils and resins stored in the wood, and in eastern red cedar those oils sit mostly in the heartwood. But a pleasant smell is no guarantee of safe dust: several of the most aromatic species are reported skin or respiratory irritants. This guide compares ten workshop woods and two rare perfume woods by scent, hardness and reported reactions, and shows how to refresh a faded scent.

Among woods a woodworker can actually buy, the Wood Database describes eastern red cedar, Spanish cedar, western red cedar, incense cedar and camphor as having distinct, recognizable scents. Sandalwood and agarwood are the classic perfume woods, but both are rare and regulated. This page is the cross-species overview. For cedar-only rankings, see our guides to which cedar smells the best and what wood smells the best.
Where Wood Fragrance Comes From
In eastern red cedar the aromatic oil sits mainly in the heartwood. A USDA Agricultural Research Service and Forest Products Laboratory paper notes that sapwood holds very low amounts of cedarwood oil compared with heartwood, which is why small trees, being mostly sapwood, yield relatively little of it.

The same paper reports that a typical steam-distilled cedarwood oil contains about 15.8% cedrol and 27.2% alpha-cedrene, and that the heat and water of steam distillation convert some cedrol into cedrene. In other words, the oil in a bottle is not chemically identical to the oil sitting in the wood.
That last point matters for buying. Wood Database odor entries for western red cedar, sassafras, bald cypress and eastern white pine all describe the smell as noticeable while the wood is being worked, so a fresh cut or a sanded surface smells stronger than a weathered board. For aromatic red cedar, the heartwood is reddish or violet-brown and the sapwood is pale yellow, so boards with less pale sapwood are the better bet for scent.
Aromatic Woods Compared: Scent, Hardness and Reported Reactions
Scent and reaction notes below are paraphrased from the Wood Database species profiles; hardness is Janka side hardness in pounds-force.
| Wood | Scent character | Janka (lbf) | Reported reactions |
|---|---|---|---|
| Eastern red cedar (Juniperus virginiana) | Distinct, tell-tale cedar scent | 900 | Skin and respiratory irritation reported |
| Western red cedar (Thuja plicata) | Strong, lingering aromatic scent when worked | 350 | Plicatic acid and other compounds; higher rate and severity of allergy, including occupational asthma |
| Spanish cedar (Cedrela odorata) | Distinct, lingering, cedar-like scent | 600 | Dust reported as a respiratory irritant |
| Incense cedar (Calocedrus decurrens) | Spicy, the classic pencil smell | 470 | Skin irritation reported |
| Alaskan yellow cedar (Cupressus nootkatensis) | Similar to raw potatoes | 580 | Skin irritation reported |
| Port Orford cedar (Chamaecyparis lawsoniana) | Pungent, ginger-like | 590 | Skin irritation, runny nose, asthma-like symptoms; prolonged sawdust inhalation linked to kidney problems |
| Camphor (Cinnamomum camphora) | Medicated chest-rub scent | 950 | Skin and respiratory irritation, headaches, asthma-like symptoms |
| Sassafras (Sassafras albidum) | Spicy, resembling root beer when worked | 630 | Sensitizer; oil toxic and weakly carcinogenic if ingested |
| Bald cypress (Taxodium distichum) | Somewhat sour when worked | 510 | Sensitizer; usually respiratory irritation |
| Eastern white pine (Pinus strobus) | Faint and resinous when worked | 380 | Allergic skin reactions and asthma-like symptoms in some people |
Two things stand out. First, fragrant does not mean pleasant: Alaskan yellow cedar smells like raw potatoes and bald cypress reads as sour, so the word “cedar” in a name tells you little about the smell. Second, scent has no link to hardness. These woods range from 350 lbf for western red cedar to 950 lbf for camphor, so choose the species for the job first and the smell second.
Does a Fragrant Wood Repel Moths?
The sources we read make a limited claim. The Wood Database says aromatic red cedar is commonly used in closets and chests to repel moths and other insects, and that camphor scent is reported to ward off moths and inhibit silver tarnish. The USDA paper above states that eastern red cedar is known for repellency to several insects including clothes moths, citing a 1952 study of cedar oil vapors. We found no equivalent moth claim for the other woods in the table, and we have not run any repellency tests ourselves. For the detailed numbers, see does cedar help with moths and which cedar works best against moths.
How Long Does Wood Scent Last, and How to Refresh It
There is no trustworthy universal number. We found no independent lab figure for how many years a wood keeps its scent, so year counts on product listings are the seller’s claims. What a home-improvement columnist, James Dulley, explains in his cedar closet refresh column is the mechanism: pores clog with dust and dirt, and most surface oils have evaporated. His fix, and the one most guides repeat, is a light sanding.
- Test a small spot: sand a patch of wood lightly with medium-grit paper and smell it to confirm the oil returns.
- Vacuum first: clear the dust that is clogging the surface before sanding the rest.
- Sand lightly: take off only a thin layer to open the pores; heavy sanding wastes thin boards.
- Do not seal it: Dulley warns that varnish, urethane or any sealer blocks the scent.
- If it is already sealed: you have to sand through the finish to reach the wood again.
Wear a dust mask for this, since the Wood Database reports respiratory irritation from several of these species. For cedar-specific refresh detail, see our aromatic cedar guide.
Best Uses by Scent: Chests, Humidors, Carving and Pencils
- Closets and chests: aromatic red cedar is listed for closet and chest linings, carvings and small specialty items. Camphor is sometimes used for trunks and chests, but the Wood Database says it is rarely exported as lumber.
- Humidors and cigar boxes: Spanish cedar is a favorite for cigar boxes because of its lingering scent. See how to make a wooden cigar humidor.
- Pencils: incense cedar is one of the primary pencil woods, and its spicy smell is the familiar pencil smell.
- Shingles and siding: western red cedar is used outdoors, where its scent is a side effect rather than the point. See cedar vs red cedar and cedar vs redwood.
- Carving: sandalwood is valued for carving as well as fragrance, covered next.
Rare and Protected: Sandalwood and Agarwood
The two classic perfume woods are not shop lumber. According to Wikipedia, Indian sandalwood (Santalum album) is classed Vulnerable by the IUCN, its trunk starts developing fragrance after about 10 years, and it is not ready to harvest until after 20. Wikipedia also reports about 90% santalol in its oil, far higher than Australian sandalwood at around 39%.
Agarwood comes from Aquilaria trees and forms when the tree secretes resin in response to a fungal infection, which turns pale heartwood dark and resin-saturated. The same source says all Aquilaria species have been listed in CITES Appendix II since 2004 and that adulteration of the wood and oil is common. Our advice, not a sourced rule: if a listing offers cheap sandalwood or agarwood chips, ask for the exact species and documentation before paying. Wikipedia is a secondary source, so treat these figures as background rather than specifications.
Smoking and Burning: Fragrant Does Not Mean Food-Safe
A wood that smells wonderful in the shop says nothing about whether its smoke belongs near food. The Wood Database reports that sassafras oil from roots and wood is toxic and weakly carcinogenic if ingested, even though the wood smells pleasantly spicy. For smoking, use woods and pellets sold for that job: see how to use wood pellets in a smoker. For cedar as fuel, see can cedar be used for firewood.
Dust Safety: Fragrant Woods Are Often Irritants
Reading the table again, nearly every fragrant wood carries a reaction note. The most serious in the sources is western red cedar, which the Wood Database ties to a higher rate and severity of allergic reactions than other commercial woods, particularly occupational asthma. Port Orford cedar sawdust is linked to kidney problems with prolonged inhalation. Use dust collection and a respirator when cutting or sanding any of them, and see can you be allergic to cedar wood for symptoms. This is general guidance drawn from the Wood Database, not medical advice.
Fragrant Wood vs Essential Oils
Solid wood and distilled oil are different products. As noted above, steam distillation changes the cedrol and cedrene balance compared with the wood itself. This page makes no aromatherapy health claims. If you want the oil side, see cedarwood oil diffuser.
Frequently Asked Questions
What is the most fragrant wood?
No single wood wins, because fragrance is subjective. Sandalwood and agarwood are the classic perfume woods, but both are rare and protected. Among woods you can actually buy for projects, eastern red cedar, Spanish cedar, western red cedar and camphor have the most recognizable scents in the Wood Database profiles.
Does fragrant wood lose its smell?
Yes, the surface scent fades. One syndicated home columnist, James Dulley, attributes this to cedar pores clogging with dust and surface oils evaporating, and suggests lightly sanding to bring fresh oils up. We found no independent lab figure for how many years scent lasts, so treat any year count on a product listing as the seller’s claim.
Is Spanish cedar a real cedar?
No. The Wood Database notes that Spanish cedar (Cedrela odorata) is a member of the mahogany family rather than a true cedar, even though its scent is described as cedar-like and lingering. That scent is why it is a favorite for cigar boxes and humidors.
Can fragrant woods cause allergic reactions?
Yes, several can. The Wood Database lists skin or respiratory irritation for eastern red cedar, Spanish cedar dust, camphor and eastern white pine, and links western red cedar compounds to a higher rate and severity of allergic reactions, including occupational asthma. Wear a respirator and use dust collection when sanding or cutting them.
Is a good-smelling wood safe to smoke food with?
Not automatically. Smell in the shop says nothing about whether the smoke belongs near food. Sassafras, for example, smells pleasant while being worked, yet the Wood Database reports its oil is toxic and weakly carcinogenic if ingested. Use woods and pellets sold specifically for smoking.
Choosing a Fragrant Wood
Pick the species for the job first: aromatic red cedar or Spanish cedar for closets, chests and humidors, incense cedar for pencils, and western red cedar for outdoor work where scent is incidental. Favor heartwood over pale sapwood, never seal a surface you want to smell, and refresh faded scent with a light sanding. Treat sandalwood and agarwood as protected, specialty materials, and respect the dust of every species in the table.
