Balsam Poplar (Black Cottonwood)

Balsam poplar is the name we use at Deschampsia for preparations made from black cottonwood, Populus trichocarpa. This fast-growing native tree thrives along western North American rivers and floodplains. Its broad leaves and drifting cottony seeds are familiar sights, but its most prized aromatic material appears earlier in the year: sticky, fragrant buds collected before they open.

Black cottonwood is also known as western balsam poplar. The shorter name balsam poplar is shared with another species, Populus balsamifera, whose resinous buds belong to the same wider herbal and aromatic tradition.[1]

Bud resin and herbal traditions

Aromatic poplar buds have a long history in infused oils and salves, often called Balm of Gilead. Herbalists traditionally describe these preparations as balsamic (richly aromatic and resinous), vulnerary (associated with wound-care traditions), and anodyne, an older herbal term for preparations used to ease discomfort.

Among the documented traditions of black cottonwood, accounts from the Cayoose Creek Band of Sekw’el'was describe bud salves rubbed into sore muscles and joints, as well as resin preparations applied to skin injuries.[2]

The honeyed, warm-balsamic fragrance has also made poplar buds interesting to perfumers. Their aromatic extracts bring sweet, resinous and sometimes subtly woody qualities to natural fragrance compositions.

Salicylates and other constituents

Poplars belong to the willow family, whose chemistry includes salicylate compounds connected to the history of herbal preparations and the scientific study of salicylic acid.

Salicin, found in members of this family, can be metabolized into salicylic acid after ingestion. Research specifically examining P. trichocarpa buds identifies the related salicylate glycosides salicortin and tremulacin, alongside aromatic constituents including benzyl salicylate and benzyl benzoate.[3, 4]

The protective bud resin is also rich in dihydrochalcones, a group of flavonoids that contribute to its distinctive chemical profile. This combination of phenolic compounds, salicylates and aromatic materials makes black cottonwood buds particularly interesting from both botanical and perfumery perspectives.[3]

At Deschampsia

Cottonwood buds are often our first harvest of the year. We collect P. trichocarpa buds for infusion into jojoba in Balsam Poplar Aromatic Resin Perfume Oil, and distill them for our seasonal Balsam Poplar Hydrosol.

The perfume emphasizes the rich, honeyed resinous character of the buds, while the hydrosol offers a lighter aromatic expression of the same spring material. Naming both Balsam Poplar connects our work to the wider tradition of aromatic poplar preparations, while the botanical name identifies the species we harvest.
