Cottonwood Bud

Winter’s Balm, First Medicine, Water Keeper.

As I walk along the Nisqually River I see giant cottonwood trees towering above the tops of the alder and the big leaf maples.  Luckily, windstorms have knocked down many large branches with their swollen buds, making my work easy.  These are the prize I am after today.  As I squish the buds, a reddish resin sticks to my fingers.  It has a strong fragrance all its own – reminiscent of pine and honey.  This resin contains a medicine that eases sore muscles, arthritic joints and helps to heal damaged skin.

Other names: xW31?3’p2li (Twana), Balm of Gilead, Populus trichocarpa

Identifying Cottonwood:  This towering tree grows to 100 feet tall and prefers wet areas like river valleys and flood planes.  Catkins open before the leaves appear and turn to seeds, covered with white, fluffy hairs that are carried great distances by the wind.  Hence their name “snow in summer.”  Leaves have rounded to heart-shaped bases and finely toothed edges.

In spring, bees chew the resin from cottonwood and digest it with their own enzymes to make bee medicine and glue called propolis.

When to Harvest:  Buds appear on cottonwood trees from late winter to early spring. You can smell the fragrance in the air on the first warm days.  Just before they open, the leaf buds will exude a drop of red to yellow colored resin. When you pinch the buds and see resin inside, it is the perfect time to gather them.  You will notice that some of the buds have catkins inside.  These do not have as much resin and are less preferred for medicine than the leaf buds.

If you are lucky, a windstorm will knock down the tallest branches for you.  These are the ones with the largest buds.  Snap the buds off the branches and place them in a plastic bag.  Sticky resin will adhere to your fingertips and anything else it touches.  While it smells wonderful, this can be a very messy endeavor.  To remove it, rub your hands with oil or rubbing alcohol, then wipe them off with paper towels.  One friend from Squaxin discovered a helpful trick.  Rub your hands with salve or an oily lotion before gathering them.  The oil will help prevent the resin from sticking to your fingers.

Making Cottonwood bud Oil

This is a messy process but I promise it will be worth the effort.  You will need: extra virgin olive oil (enough to cover the buds), a double boiler, a blender (only if you are making a large amount), a pressing cloth like muslin, a strainer and a glass jar for long-term storage.  If you do not have a double boiler you can create your own by placing a small pot in a larger pot with an inch or two of water in it.

Step 1 – blend or pinch open the buds.  This will help the resin to more easily release into the oil.  If you have a small amount you can simply pinch the buds with your fingernail.  Place directly in a double boiler and cover completely with olive oil.

For larger amounts, using a blender will save you a considerable amount of time.  First, place your buds in a double boiler and cover them with olive oil so they are fully covered ½ to 1 inch above the buds.  (If you put the buds in the blender directly without oil they will stick to the sides and your clean up will be much more challenging.)  Pour oil and buds into the blender.  Turn on and blend just until the buds are mostly broken open.  Place back in the double boiler.

Step 2 – Gently heat.  Heat on a very low setting.  Do not allow the olive oil to get hot enough that it boils!  You can turn the burner on and off to keep the temperature low.  Heat for several days.  The oil will turn a deep golden color and become very fragrant.


Step 3 – Press out the oil.  Lay a piece of muslin cloth over a strainer that is sitting on a container.  Pour a couple of cups of buds and oil into the muslin, bundle it up, twist the cloth and squeeze with all your might.  Once oil stops dripping, empty the buds into a compost container and continue pressing until done.  Let the pressed oil rest for an hour or so.  If there is any water or solid material it will fall to the bottom of your container.

Step 4 – Store.  Pour your oil (minus any water or solids that might be at the bottom) into a glass storage container.  You can use any glass jar with a tight fitting lid.  Amber jars are nice because they protect the oil from sunlight, but you can keep clear glass containers in a cupboard in a cool place and the oil will preserve just as well.  Remember to label – although the smell of this oil makes it easy to identify.

Helpful hint:  to clean your containers, wipe oil off with a paper towel and then clean with soapy water.  It is easier to get resin out of a double boiler when the oil is warm.  If resin remains, wipe with a paper towel soaked in rubbing alcohol (the higher the alcohol content the better).  For extreme cases you can soak with a little alcohol overnight.

Cottonwood Medicine

“Populus” means the peoples’ tree.  This scientific name comes from the fact that cottonwood has proved to be so useful over the centuries.  Many parts of the cottonwood tree are medicinal. A compound called salacin, which is found in the leaves, buds and bark of cottonwood, has been proven to lower fevers and reduce inflammation and pain.  The resin has been used to waterproof boxes and baskets, and the bark has been used to make buckets for storing and carrying food.

Cottonwood oil is especially helpful for swollen arthritic joints and sore muscles.  It is deliciously fragrant and is added to lip balms, body oils and healing salves.  The body oil is a nice after-bath moisturizer.  It also makes an excellent massage oil for sore muscles.  Because cottonwood is high in antioxidants, it is useful for healing the skin, including sunburn.  The buds are also antiseptic and can be added to other herbal oils to prevent rancidity and molding.

One potential use of cottonwood is that you can cut a small branch and place it in a vase with other plants you would like to root.  Cottonwood and other willows produce rooting hormones – an ingenious adaptation to help branches that float down rivers or streams root in the banks, thus spreading their range.

Caution:  Although I have never heard of anyone being allergic to cottonwood bud oil, you may want to avoid it if you are allergic to bees or aspirin.

  1. My son gets a rash when I put it on his skin. I’ve had to stop using it in salves. He also has strong reactions to bee stings. Although not allergic.

    Love it otherwise!!!

  2. If the oil gets too hot is it ruined?

    • That depends. You will lose a lot of aromatics if the oil gets too hot but it probably still has medicine. You can use it as a body oil.

  3. My daughter is highly allergic to cottonwood be sure if you use it be sure no tree allergies.

  4. I really would love to have the cottonwood bud oil recipe sent to me so I can put it in my recipe file. I have looked and asked around if anyone know`s how to make it, no luck. A lot of the older people are gone. Thank You So Much , Debra

  5. Thank you so much for sharing your process! Im so very grateful!

  6. This is the first time making this, I was wondering I didn’t have Olive oil, so would Wesson oil be good to use too? Thank you!

    • Olive oil is best because it has natural Vitamin E and will last longer. It is also good for your skin. If you do not have anything else vegetable oil would work. Sometimes you can get extra virgin olive oil for inexpensive at grocery outlets. Hope that helps! Grapeseed oil is also a good choice.

  7. I’ve suffered with athletes foot for many years. I finally tried cotton bud oil on it and it has cleared it up within a week.

  8. I live right down the street from the nisqually river. Are there usable buds yet?

    • Yes, I am starting to see buds that are swelling. I would wait until the leaves fall off the trees. The buds are biggest and most resinous in January-February but they would be fine to harvest now. Look for big branches that fall down in a wind storm.

  9. Would coconut oil work? I want to make more of a balm to use for diaper rash.

    • Yes, you can definitely infuse them in coconut oil by gently heating them with the oil in a double boiler. Sounds wonderful and it is the perfect time!
