I’ve spent part of the the last couple days harvesting copious amounts of Cottonwood bark from abandoned beaver cut trees. Although I prefer to gather this particular bark in Spring while I’m also harvesting the sticky resinous buds, the opportunity is far too good to pass up. In the past I used my standard hunting/harvesting knife for peeling bark, but if you’ve ever done it, you know it’s a slow process. This year Wolf gave me a great invention, a draw knife, which is a long blade with a handle at each end. I love this thing, it cuts the peeling time down to a fraction of my usual time. Now, usually I don’t even take bark this way, because I don’t like to cut a whole tree in order to get some bark. My normal practice is to gather twigs and use them, this makes for great medicine and does little harm to the tree. In this case, the trees were already downed so I went for the actual body bark.

I now have, I dunno, about seven pounds of fresh bark and I’ll probably get another five tomorrow. Cottonwood is one of my favorite medicines so this is a welcome addition. First, I cut the five foot long strips of bark into reasonable lengths for drying and storage. Next, I choose premium pieces for liniment, salve, vinegar and tincture. Next, I roughly chop it and fill the various bottles before filling again with the chosen menstruums.

One of my favorite uses for Cottonwood is a salve made from the January buds, this is a great pain reliever for arthritic joints, injuries, tendinitis and other similar sore body parts. It also makes a good chest rub all by itself. Michael Moore says to think about it as a replacement for Wintergreen oil without the chance of toxicity that the latter has. The buds are the strongest part of the plant, and a tincture of them makes a great expectorant for congested chest colds. The buds are not very soluble in water, so I mostly make oil and alcohol based preparations of them. The bark and leaf are more available in water, so I use the bark every which way and use the leaves in teas. All parts of the tree are pain relieving (as most members of the Willow family are) and can be used internally for the same kind of pain you might take an aspirin for, and can also be used to help bring down fevers when that’s appropriate. The amount of pain relieving constituents in each stand of trees seem to vary somewhat so it’s helpful to get to know your local trees and gather from them consistently so you can judge your doses more accurately.

Cottonwood is also an effective bitter stomach tonic, and I use it many of my bitters mixes, along with Wild Licorice, Oregon Grape Root, Wild Cherry and Orange Peel. The bark macerated in Apple Cider Vinegar makes a great general stomach tonic, and works well for appeasing a sour stomach with rotten egg burps, an unpleasant but useful detail.

Another similarity with other Willow family trees is it’s gentle, persistent effect on the kidneys and bladder. It seems to be most useful in chronic, slow to heal infections rather than acute, scalding infections. It has a tendency to make the urine more acid, and to help tone up the mucus membranes. I like it with Bidens for chronic UTIs and prostate enlargement and it also is quite useful to tone the uterus and vaginal muscles. The medicine as a whole is most useful in cases where tonification and warmth is needed, however, it can also be helpful in certain cases of chronic inflammation when accompanied by weakness. It’s less warranted where there’s excessive irritation or great heat.

A salve made of any part of the plant is incredibly useful in a general wound salve, reducing inflammation, encouraging healing, eradicating bacteria and tightening surrounding tissue. Nearly every salve I make has at least a portion of Cottonwood in it, what part of the tree I use is dependent on season and availability. I especially love the rich, river in the spring scent of the bud resin oil, which I use very similarly to how most use propolis. It’s also a very useful antioxidant and I add it to other oils to keep them from going rancid. It’s possible to make a really nice butter salve with the buds waterbath infused in ghee.

Cottonwood is another one of my top ten most valuable herbs that I can’t live without. I also love that it’s abundant and common throughout the West, making for easy and sustainable harvest. All of the Populus spp. including Aspen, Balsam Poplar and Cottonwood can be used fairly interchangeably, and those with the most and smelliest resin make the best salves. They make great beaver food too. ;)

  1. [...] And of course both bud and bark have many internal uses as well. I recently wrote more about in a longer post on Cottonwood, and Darcey just wrote a post including many Cottonwood tidbits as well. This very valuable [...]

  2. What is the smelliest wild herb indigenous to the Pacific Northwest? One that might be used to keep away mosquitoes?

    Thank you

  3. Well, I’m from the SW not the NW, so I’m probably not the person to ask… it’s not indigenous but there’s probably lots of catnip up there, mosquitoes hate that…. We don’t have much in the mosquitoes here so I rarely use any deterrents. I have used the wild pennyroyal (hedeoma), that’s native here (but I don’t know about where you are) and very useful.

    An old recipe from Juliette Levy is an infused oil of Rue, Wormwood and Rosemary.

  4. Very interesting website. I had been looking for some info on cottonwood harvesting. I had been in Oregon and they grow it there commercially and it is used mainly for toilet paper. I had the opportunity to see them harvesting the cottonwood from the roadside. They use a machine that snips them right off at ground level.

    The use you are putting to this plant is every bit as needed as those of the commercial producers.

  5. Thanks for reading, Dave…. actually, I’d say that the renewable medicine this tree can provide is far more important than a disposable luxury product like toilet paper.

  6. Thank you for this information. I know that willow bark is the basis of aspirin. Does cottonwood help in that direction?
    It is not that I need it but I am writing a book, taking place in the 1880’s and the main character is a hypochondriac.
    I got direction to you from Dave who posted to you.
    The older one gets the more one wonders how many medicines are tossed to the wayside, because it is cheap and available, making them unprofitable to the pharmaceutical industry.
