My kindergarten school picture is the first evidence of a lifelong love affair with trees, and pine in particular. My dad had planted a little grove of white pines (Pinus strobus, Pinaceae) in our backyard. I spent my afternoons playing in their whorled branches, unwittingly collecting resin in my locks while leaning my head against their sturdy trunks. My mom cut out the sticky parts, resulting in a hairstyle that could only be rivaled by the likes of Pippi Longstocking.

There are over one hundred species of pine worldwide, and most have recorded medicinal uses. Cultures around the globe have used the needles, inner bark, and resin for similar ailments.^1,2,3 Internally, pine is a traditional remedy for coughs, colds, allergies, and urinary tract and sinus infections. Topically, pine is used to address skin infections and to lessen joint inflammation in arthritic conditions.⁴ Native people across the continent—including the Cherokee, Chippewa, Iroquois, Apache, Hopi and countless other groups—have used over twenty species of pine in a similar medicinal fashion.¹

Along with its myriad medicinal applications, pine is a source of lumber, food, essential oil production, and incense. There are a few species of pine in North America and a handful of species in Eurasia that yield the familiar edible pine nuts. Pine is essential commercially for its lumber and pulp, which is used to make paper and related products.

Many species of pine are considered cornerstone species, playing a central role in their ecological community. See my article on longleaf pine here. Finally, many species are planted ornamentally for their evergreen foliage and winter beauty.

Medicinal Use of Pines

Pine Needles

The fresh needles and buds, picked in the springtime, are called “pine tops.” These are boiled in water, and the tea is consumed for fevers, coughs, and colds. The needles are also diuretic, helping to increase urination. Pine-top tea is one of the most important historical medicines of the rural southeastern United States, especially given pines’ abundance in the region. Renowned Alabama herbalist Tommie Bass used the needles in a steam inhalation to break up tenacious phlegm in the lungs. I combine pine tops with sprigs of fresh thyme (Thymus spp., Lamiaceae) and bee balm (Monarda spp., Lamiaceae) for this purpose. Tommie Bass reported “ the country people used to drink pine top tea every spring and fall to prevent colds.”⁵

I enjoy the needles—fresh or dry—as a fragrant and warming wintertime tea. It pairs well with cinnamon bark (Cinnamomum verum, Lauraceae) and cardamom (Elettaria cardamomum, Zingiberaceae). Pine offers relief in sinus and lung congestion through its stimulating expectorant, antimicrobial, and anti-inflammatory qualities. The fresh, younger needles also contain Vitamin C.

Try combining peppermint (Mentha x piperita, Lamiaceae) and catnip (Nepeta cataria, Lamiaceae) with pine needles as a tea, which can be sipped upon throughout the day to assuage cold symptoms. This combination is a safe remedy for the whole family.

Pine Bark

The inner bark contains more resin and is more astringent than the needles. It has been used historically as an antimicrobial wash or poultice and infused in bathwater for muscle aches and pains. It’s also boiled in water and ingested as a remedy for coughs and colds. In Traditional Chinese Medicine, the knotty pine wood from several species of pine is infused in wine and used topically for joint pain.³ I tend to reserve the bark for topical applications since the needles are easy to harvest and more pleasant tasting. 

Pine Resin

The resin, also called pitch, has many local first-aid uses—it’s used as an antimicrobial dressing on wounds and to pull out splinters. Pine resin, in minute quantities, has been used internally as a powerful expectorant but it does have some toxicity, so I recommend sticking to the needles or bark when it comes to internal use. I use pine pitch, prepared as a salve, to draw out splinters, glass, and the toxins left from poisonous insect bites. Pine resin salve is helpful to lessen muscle aches and joint inflammation.

Journal page about Pine identification.

Pine Identification

The first step in identification is to make sure you have pine and then narrow it down to the exact species. To accurately identify pine, look for the characteristic two to five needles growing together in a little bundle (called a fascicle), coupled with the familiar pinecones. Each bundle has a little papery sheath at the base. (Note: a few species of pine only have one needle; however, this is an anomaly, and most species bear two to five needles in a bundle.)

Identify the species local to your area and research their traditional uses. That said, it’s important to know that no pine is harmful and the medicinal uses overlap between species, so if you can’t find any information about your local pines, they are still medicinal. Just make sure it is indeed a true pine (in the Pinus genus) by checking for the identification traits listed above, and you’ll be good to go!

The flavor of pine varies depending on the species and the time of year the needles are picked. The needles have an astringent, “puckering” effect (similar to strong black tea) and a slightly resinous flavor; some pines possess a mineral tang, reminiscent of seawater. Some have needles that are quite sour, especially in the spring. After proper identification, chew on a bit of the needles to get an idea of how the various pine species in your area measure up.

Pine Look-Alikes

Other conifers have cones that are sometimes mistaken for pinecones, so be sure you have a real pine and not some other cone-bearing evergreen. Many conifers have similar medicinal properties to pine—spruce (Picea spp., Pinaceae) and fir (Abies spp., Pinaceae), for example. One simple visual indicator that set these two trees apart from Pinus species: both spruce and fir have needles that connect directly to the branch, as opposed to the fascicle in pines.

It’s crucial that you are extremely careful to not harvest yew (Taxus spp., Taxaceae), which is a conifer with poisonous needles.⁶ Yew produces a red fleshy fruit (technically a cone), unlike the familiar hard brown cones you see growing on other conifers. Other species of conifers, including yew, have precautions, or possible toxicity, so proper identification of pine is crucial.

Pine Imposters

Be aware that many species of trees with pine in their common name are not true pines and are not used in the same way, and may even be toxic. For example, Australian pine (Casuarina spp., Casuarinaceae) and Norfolk Island pine (Araucaria heterophylla, Araucariaceae) aren’t even in the same family as the true pines! As with any plant you harvest from the wild, you’ll need to use the identifying characteristics, along with the scientific name, rather than the common name.

Harvesting Pine

You can harvest pine needles anytime they’re looking good and so are you. Seriously though, the needles can be gathered anytime they are needed, but the fresh springtime tips are more pleasant in taste and tend to be a little more sour than older needles. Cut the tips of the branches using garden scissors or shears, and dry in baskets.

Harvest the bark in the spring, preferably from a tree that needs to be thinned or a tree that’s fallen in a storm. You can alternatively collect a three-to-four-inch diameter branch from a tree, which leaves only one wound on the tree. The outer bark is removed and composted, and the inner bark—the medicinal portion—is scraped free from the wood. Dry on a screen or in a loose-weave basket.

Whenever you go on hikes or camp, keep an eye out for freshly dried, amber-hued pine resin on living pine trees. It’s much easier to harvest when the golden pitch is dried but not super brittle or black. Using a small knife, cut the pitch directly into a small jar, leaving a thin layer intact on the tree (the resin serves to protect the tree from pathogens and insects after injury). Sometimes the resin is dried on the outside and squishy on the inside, so proceed carefully. You can still gather resin that is gooey but it’s messy business indeed. 

Pine resin can be dirty with adhering bugs and dirt. Avoid soiled resin if possible but if you end up with a grubby batch, gently heat the resin in a small pot and strain through a fine sieve. Clean the pan and strainer with rubbing alcohol. Store the pitch in jars for up to a few years. The medicinal resin has a distinct “piney” and resinous odor; when it’s past its prime, it will have lost its aroma.
