All About the Douglas Fir Tree

The Douglas fir tree is an evergreen conifer native to North America, although most people recognize it as one of the most popular Christmas trees. Although Douglas fir is the most widely used name, it is also referred to as Oregon pine, red fir, and Douglas spruce. Its botanical name, Pseudotsuga menziesii , literally translates to ‘false hemlock’, as it is not a true fir tree.

Even though many people associate Douglas fir trees with the holidays and the scents of winter, this popular tree has a long history of both practical and medicinal use. The needles, bark, pitch, and other parts were used by Native Americans in many aspects of their day-to-day lives. Nowadays, most people aren’t aware of the therapeutic properties of the Douglas fir tree. With the rise in popularity of essential oils, its benefits can be brought to light once again.

History of the Douglas Fir

David Douglas, a Scottish botanist in the Pacific Northwest in the 1820s, gave the tree its common name Douglas fir . He came on an expedition to find plants, and brought back over 200 plant specimens to Britain! One of these plants was the Douglas fir, and it still grows in Great Britain today. 1

A Scottish surgeon and naturalist named Archibald Menzies gave it its botanical name Pseudotsuga menziesii . In 1790, the British government appointed Menzies to accompany Captain George Vancouver on an expedition. His main responsibility was to keep note of all of the plants they came across, record their names, and determine whether English settlers could thrive as farmers. On Vancouver Island, he discovered a tree that didn’t have a name - the tree we now know as the Douglas fir.

Pseudotsuga taxifolia was the original written botanical name, which translates as “false hemlock with leaves like a yew”. It was later changed to Pseudotsuga manziesii to give credit to the explorer who first discovered the tree. 2

The tree grows from northern British Columbia, down to central California, east through the Rocky Mountains and south to northeastern Mexico. There are two different varieties, the coastal Douglas fir (subspecies menziesii ), and the Rocky Mountain Douglas fir (subspecies glauca) .

Characteristics of the Douglas Fir

Douglas fir trees can grow to immense sizes, with the tallest recorded reaching 329 feet tall in Coos County, Oregon. The largest known Rocky Mountain Douglas fir is also located in Oregon and is 139 feet tall. Only Coastal Redwoods exceed the height of these giants! 3 Coastal Douglas firs can live up to at least 500 years old, with some known to exceed 1000 years. Rocky Mountain Douglas firs have a slightly shorter lifespan, usually no more than 400 years.

Douglas fir trees have very thick, textured bark, which gives them the unique ability to withstand wildfires. The branches of very established trees are a significant distance away from the ground, which keeps their needles safe from fire. The ability to withstand wildfires gives them a leg-up in both survival and propagation. When a wildfire has cleared smaller shrubs and trees from an area, the Douglas fir tree is free to drop its seeds and sprout new life.

Legend of the Mice and the Douglas Fir

There are a few different variations of the legend of the mice and the Douglas fir, but the story is essentially the same in all.

In the story, a massive forest fire spreads throughout the Pacific Northwest, larger than any other fire the animals had ever known. All of the animals began to flee the forest, but the mice with their tiny legs were unable to keep up. They frantically ran around looking for shelter and asked a couple of different trees for help with no avail.

Finally, the mice came across a Douglas fir tree. It offered them the safety of its cones and told the mice to climb inside. The flames were close behind, and the mice made it halfway inside the cones before the Douglas fir had to close them in for safety.

Whenever you look at the cones of the Douglas fir tree, you can see the small tails and feet of the mice who crawled inside to escape the fire. 4

Historical and Medicinal use of the Douglas Fir Tree

Native Americans used the wood of the Douglas fir tree to make small utensils, tools, and fuel for the fire. The pitch could seal canoes, water containers, and joints when building.

The timber from the Douglas fir tree is extremely strong and dense, making it great for building. In more recent times, the timber has produced large beams, wood fiber in paper manufacturing, railroad ties and plywood veneer. The timber also makes furniture, fences, and flooring. 5

The needles of the Douglas fir tree contain a wide variety of terpenes, including a-Pinene, b-Pinene, limonene, camphene, myrcene, delta-3-carene, linalool, citronellol, and others. They have anti-inflammatory, antiseptic, antimicrobial, expectorant and sedative properties.

Native Americans used different parts of the Douglas fir tree to treat a wide variety of ailments. Some of these included headaches, rheumatism, stomach aches, the common cold, respiratory issues, liver problems, and arthritis. 6

The resin is highly antiseptic. It is an ingredient in a poultice to treat burns, scrapes, bites, minor wounds and other skin problems. The resin can also treat coughs, or ease the pain of sore throats by chewing on it. An infusion of bark eased excessive menstruation and stomach issues, while an infusion of the leaves helped problematic joints. An infusion of the young shoots was crucial to the treatment of kidney and bladder disorders while soaking the shoots in cold water made an effective mouthwash. 7
