Douglas Fir Essential Oil (Pseudotsuga menziesii) is an aromatic oil obtained from the needles and twigs of douglas fir, a evergreen conifer tree in the Pinaceae family native to western North America. It is known for being fresh, sweet, coniferous, and slightly citrusy with a crisp mountain-air feel and is used in aromatic practice for fresh forest atmosphere, seasonal comfort, and everyday wellness blends.

In traditional and modern aromatherapy, douglas fir oil is chosen when a blend needs supports uplifting forest-style diffuser blends with a fresh outdoorsy character. Depending on the formula, it may be used in diffuser blends, diluted massage oils, or carefully balanced body-care applications. Its scent pairs especially well with oils in the coniferous family as well as woods, resins, and supportive citrus notes.
