Beautiful walnuts reaching up to the sun in a mature forest setting!
I remember when I first met black walnut. My Great Aunt and Uncle lived on a farm, and on that farm was a colonial-era farmhouse. Near their farmhouse sat a massive black walnut tree. I remember going there when I was a young child and picking up the black walnuts for the first time when they were still green, smelling their amazing scent, and sticking a few in my coat pockets. Of course, the weather grew cold and I forgot about those walnuts in the coat pocket, and when I went to use the jacket again in the spring, I was in for quite a surprise when the brown dye of the walnut husk breaking down permeated through my jacket. Ever since that day, I felt like the walnut had provided me with an important lesson, and I am honored to be friends with such a magnificent tree species.
This post continues my “sacred trees in the Americas” series of posts; where I explore the magic, mystery, medicine, and lore of trees native to the North-East and Midwest regions of the United States. Previous trees I’ve covered include Hickory, Eastern Hemlock, Eastern White Cedar, Maple, Hawthorn, and Beech. Today, we will be looking at another powerful tree ally, the Walnut. I’m going to be focusing my comments on the Eastern Black Walnut (Juglans nigra) as that is the native walnut in my area. However, most of what I’ll write applies to walnut trees throughout the world.
About the Black Walnut
The Eastern Black Walnut (or what we just call “Walnut” or “Black Walnut”) is a tree native to the Eastern US with a large range spanning most of the Mississippi watershed. Here in Western PA, I’m actually at the very edge of its natural range (although I know people plant them north of where I am!) Black walnuts are an overstory tree, meaning they need light and grow tall, forming part of the canopy of the forest. They often are found in riparian zones which are the edge spaces between streams/rivers and the land (which typically flood in early spring and offer rich soil due to the flood plains). Black walnuts are pioneer species, similar to cherry, black birch, and black locust: these are some of the first trees to regrow damaged ecosystems.
The black walnut typically grows tall and straight, especially in the forest, out-competing other trees for the best lithg. It grows up to 130 feet tall; the tallest one we have on record in the USA is actually well outside of its native range, on the Colombia River downstream of Portland. Walnut leaves are feather-compound, with seven to seventeen narrow, toothed leaflets. They have a spicy smell when they are crushed or rubbed.
Walnut trees produce a very strong wood that is dark in color and is easily worked. It has a straight grain, it holds shape well, and is a solid with few pores. In fact, walnut wood is so valued that sometimes people poach walnut trees (which is, in my opinion, a terrible tragedy!) Because of this, there are less and less walnuts, so we all could do some good by planting more. In fact, in the history of Pennsylvania, black walnut trees growing in groups were often a sign to the Pennsylvania Dutch (German) of good soil fertility, likely due to their connection and growth on flood plains of rich soil.
Walnut as an Expeller
One of the few things people often know about black walnut is that it is allelopathic, meaning that it produces a chemical called juglone that oxidizes in soil and prevents certain kinds of other plants from growing under or near it. It also can increase the soil alkalinity around the roots. Some plants, like black raspberry or serviceberry, have no difficulty growing under black walnut. Others, like tomatoes, pines, apples, or birches, cannot grow and will be poisoned by the juglone. This has been well known and documented for centuries, the whole way back to Pliny the Elder (the same Pliny that has preserved the famous druids harvesting mistletoe ritual and druid egg lore) who wrote, “The shadow of the walnut trees is poison to all plants within its compass.” Juglone is concentrated in nut hulls, roots, and buds; to a lesser extent, it also occurs in leaves and stems.
I want to note, and I’ll come back to, the importance of the doctrine of signatures here. A traditional definition of this concept is that the plant heals and works with what it looks like or how it acts. In earlier posts on this series, I’ve proposed an equivalent doctorine of signatures for the magical properties of trees and plants–and so, we will return to this expelling quality towards the end of the post.

Walnut as a Food Source
Walnut is considered a nut of the gods; in fact, the word juglans goes back to “jovis glans” or “nut of Juipter.” I think this speaks volumes about Black Walnut and its power and gifts.
Rather obviously, Black Walnut produces a really delicious edible nut—the black walnut nut is not easy to crack, but is well worth the effort! Like many other hardwood nut trees, most walnuts produce a really good harvest every few years, and need sunlight in order to do so. In years where there is a good crop, you can harvest them in abundance. I typically will let the outer husks rot down and the little worms crawl out, and then once they have lost their husks, I remove the remainder and let them in their hulls till I’m ready to crack them. Cracking them requires patience and some determination but is well worth the effort. I typically crack them with a hammer or small mallet on a stone–one good swing and they will be ready to eat. Put your cracked nuts in a bowl (shell and all) and then sit down with some friends to pick through them, removing the nutmeats (you might also need one of those small nut pick metal things). Its nice to do this by a warm fire!
In addition to the people who enjoy the nuts, squirrels use them as a primary food source. When you are walking through the forest, you can always find out where the black walnut trees are by seeing how the squirrels have left their beautiful chewed black walnut hulls behind! These are lovely for crafts and altars and take quite a while to break down and return to the land.
You can tap black walnuts similar to how you tap sugar maples (I haven’t tried this because I didn’t have large enough black walnuts). I think this would be just delightful, however, based on the deliciousness of the nut!
Finally, pressed walnuts make a lovely walnut oil (which you can find in specialty shops or online). Walnut oil is a wonderful oil for cooking (I like to use it for salads and dressings) with a very rich nutty flavor. Walnut oil also is very useful for sealing wood, like wooden spoons, especially when you’ll be eating from them. I use walnut oil on my wooden bowls and spoons every few months to keep them in nice shape. I haven’t tried to press my nuts, and my guess is that most of the walnuts that are pressed are English Walnuts, which are easier to crack and eat. But you could certainly press the black walnuts if you were able to gather and crack enough of them!
Making Walnut Ink
One of the things I love to do with black walnuts is to make ink from them. I have a whole post dedicated to the subject of natural ink making, and I’ll direct your attention there for more details and will supplement those instructions here. In a nutshell (hah!), black walnut ink is best made once the hulls have gone brown (and usually wormy!). Put the whole nut – hulls, nuts and all, into an old pot and cover them with white vinegar. Boil them for an hour or so and let cool. Yes, this will make your house smell very weird. Strain the ink to begin to get out the bits of hull. I have found that it requires straining over and over again with finer and finer strainers to get all the husk pieces out–but it is well worth the effort. Once your ink is strained, return the ink to the pot and boil it down until you are happy with the consistency (usually about another hour). You might strain it again at this point with a very fine strainer. If you want to improve the viscosity of the ink (that is, improve how well it flows, especially through a dip pen) you can add a bit of Gum Arabic to it. I recommend using the commercially prepared Gum Arabic liquid you can get at art stores, not the resin that you need to powder up–the resin produces some lumps regardless of how fine you grind it! Let your ink cool, put it in a jar, label it, and you have a very lovely ink that will stay good for many years and can be used for many purposes!
Medicinal Actions of Walnuts
Black Walnut has had a large range of uses within traditional western herbalism: I’ll summarize some of the most common here.
According to M. Grieve’s Modern Herbal, the bark and leaves of the walnut are alterative, laxative, and astringent, and are specifically used for skin issues like eczema, herpes, and other skin conditions. Grieve also suggests that the juice of the green husks, boiled with honey, is really good for a sore throat/gargle. Matthew Wood, in the EarthWise Herbal, suggests a similar condition: the use of the leaves for external eczema, ring worm, itch, shingles, tumors, abscesses, boils, and acne. The leaves, used internally, can also be used for tonsillitis, sore throat, hoarseness, internal ulcers and inflammation. In large quantities, Grieve notes that the dried and powdered bark, as a strong infusion, is a purgative (makes you vomit!).
Matthew Wood suggests the hulls are useful for a wide range of things, but I have used them most frequently to deal with internal parasites, worms, and so on. A tincture of green nuts is particularly useful for dealing with internal parasites and worms (I have used this for worming animals, like chickens, as well in very small does). Other uses include low functioning thyroid and low functioning metabolism.
Mentally, Wood also has a suggestion that is directly in line with the expelling properties suggested by the doctrine of signatures. He suggests it is useful when you are “too much under the influence of another person, thought, and scheme.” I fully support this use and have used it this way myself. Further, when I was at the American Herbalist Guild Annual Symposium, Matthew Wood also suggested that Black Walnut was particularly good for children or young adults who had experienced bad divorces; it allowed them to get beyond the experience. Wood suggests for any use of black walnut, small doses are appropriate (1-3 drops, 1-3x a day).
Here’s an old time recipe from Grive’s Modern Herbal:
‘To preserve green Walnuts in Syrup
‘Take as many green Walnuts as you please, about the middle of July, try them all with a pin, if it goes easily through them they are fit for your purpose; lay them in Water for nine days, washing and shifting them Morning and Night; then boil them in water until they be a little Soft, lay them to drain; then pierce them through with a Wooden Sciver, and in the hole put a Clove, and in some a bit of Cinnamon, and in some the rind of a Citron Candi’d: then take the weight of your Nuts in Sugar, or a little more; make it into a syrup, in which boil your Nuts (scimming them) till they be tender; then put them up in Gally potts, and cover them close. When you lay them to drain, wipe them with a Course cloth to take off a thin green Skin. They are Cordial and Stomachal.’ – (From The Family Physician, ‘by Geo. Hartman, Phylo Chymist, who liv’d and Travell’d with the Honourable Sir Kenelm Digby, in several parts of Europe the space of Seven Years till he died.’)
Walnut in the Western Magical Traditions
Black walnut is considered a “masculine” tree associated with the element of fire and the sun. Culpepper, in his Complete Herbal, writes, “This is a plant of the sun. Let the fruit of it be gathered accordingly, which as the most virtual whilst green, before it shells.”
The forest canopy of walnuts!
In the American Hoodoo tradition, walnut leaves and nuts are used to put jinxes on people. Walnuts are also used to “fall out of love”; Yronwode in her Hoodoo Herb and Root Magic describes a ritual where you make a tea of nine black walnuts (husk and all) boiled in three quarts of water; boiling it till the water evaporates down to 1 quart. You bathe in this water, renouncing ties to the former love, and then throw the water out at a crossroads or against the tree. This kind of bath is not one for the bathtub, but usually done in a smaller tub. Again, we see this expelling or removing quality associated with the walnut present.
Cunningham, who I’m not always apt to trust, writes of walnut being tied to mental powers, infertility, health and wishes. He suggests that witches danced beneath walnut trees in Italy during secret rites (although why, he does not say). He suggests that carrying a walnut can strengthen the heart and ward of rheumatism. If you are given a bag of walnuts, you will have your wishes fulfilled. People can place walnut leaves around the head (or in a hat) to prevent headache or sunstroke. Cunningham also suggests that a woman who wanted to remain childless after marriage could place walnuts in her bodice on her wedding day—each walnut represented one year of being childless.
Unfortunately, that about sums up what most sources say about the magical uses of walnut, however, we can gain much more insight from exploring some of the lore around this tree, to which we will now turn.
Black Walnut in Lore around the World
Walnut Cracker (Native American): Walnut was an important food source for Native Americans; it was also used for talking sticks and flutes. In one story, a man is known as “walnut cracker” who was always cracking walnuts (which makes sense, giving how difficult they are to crack!). Even after Walnut Cracker died, his spirit continued to crack walnuts and would scare people so much that their sickness or illness would disappear. This shows up in several stories in the South East Native American tribes. Again, here is that same expelling quality–this time, the spirit of Walnut Cracker removes sickeness or illness through his very presence.
As a talking stick, walnut (along with pecan) represent the gathering of energy or beginning of new projects.
Other than that, I couldn’t find much in the Native American lore. Many of the other stories involving walnut primarily focus on it as a food item, including The Ignorant Housekeeper (Cherokee) who doesn’t know how to properly prepare walnuts.
Walnut Lore: Beating and Ingratitude (Greek, Roman, European): Let’s now turn to the other side of the world, where we can see stories from the European subcontinent. In fact, walnut features prominently in many tales. There is a long history of discussion of the “beating” of walnut trees to gain their huts—where folks went at walnut trees with sticks showing ingratitude for the nuts that are produced and harming the tree. These fables and references span quite some time. Two Greek Fables, for example, illustrate the plight of the walnut tree; later, Antipater of Tessalonica offered this epigram:
“They planted me, a walnut-tree, by the road-side
to amuse passing boys, as a mark for their well-aimed stones
All my twigs and flourishing shots are broken,
Hit as I am by showers of pebbles.
It is of no advantage for trees to be fruitful; I, indeed
Bore fruit only for my own undoing”
This same principle weaves its way into other early Roman poems as well as Aesop’s fable of the Walnut Tree, where it is treated with no respect. Into the 1500’s, a horrible proverb about how women, dogs, and walnuts all benefited from beating was widely circulated. This proverb continued to propagate the idea of walnut tree benefiting from beatings with sticks and rods to produce more nuts.
I’m not honestly sure what to make with this. Some trees benefit from regular pruning, but this is the first instance I’ve seen any reference to just beating the tree with sticks. Part of me wants to question, again, the difficult relationship we have between humans and nature. I’ve translated this as “gratitude” below (but I’m open to other interpretations and suggestions!)
The Wise Walnut: Hermit Philosopher. In Georgian Folk Tales by Marjory Waldrop (1894), a wise man who lived in solitude came to a old walnut tree in his garden. He questioned why the walnut tree was so tall, growing for over 100 years, yet never producing bigger fruit, while the melons and pumpkins on the ground were so massive. He thought about it, eventually falling asleep under the walnut tree. A few nuts rain down from the tree, and he marvels in how his head would have been “broken” if not for the small size of the walnut. In this tale, we see the walnut offering wisdom.
Small Beings and Things Hidden in Walnut Shell. In the traditional story of Thumbelina, a woman who wants a tiny daughter visits a witch and gets some magic barley-corn. From this corn sprouts a flower, and within the flower is Thumbelina. The woman gives Thumblina a beautiful polished walnut shell (my guess is an English walnut) for a cradle. Thumblina is later whisked away, shell and all, by an ugly toad. Thumbelina’s tale is quite similar to Tom Thumb, who also lives in a walnut shell due to his tiny size. In another tale, called Puddocky, the princes of the kingdom are given a magical mission of finding a small dog that can fit comfortably in a walnut shell, among other tasks, to become the king’s heir. In yet another story, a walnut contains a wasp whose sting is made of a diamond; and the walnut can contain the wasp within.
In another tale, this one from Popular Tales from the Norse by George Webbe Dasnet (1904), we hear the tale of “Boots and his Brothers.” A king in the land has offered his daughter and half his kingdom if the ancient oak (that grows each time it gets taken to the axe) can be felled and a well dug to hold water. As John (Boots) walks in the forest, he finds a magic axe, a magic pick, and a walnut that spills forth water. He takes these things up, plugging the hole in the walnut shell with a bit of moss. He is able to fell the tree, dig the well, and fill it with water from the walnut—thus securing half the kingdom and the princess. In each of these tales, something important or precious is kept safe within the hard shell of the walnut, suggesting some protective qualities.
Overall Magical Themes
Drawing upon all of the above lore and material, I would like to propose the following magical themes and uses for the Walnut tree. These can certainly be added to, over time, but I hope this is a good start for those of us who want to work with walnut.
Walnut as a “container” for many things and as a protector. The stories of Thumbelina, Boots and his Brothers, and Tom Thumb all speak to the magical nature of the walnut to contain or hold those small things which may otherwise get lost. Now, these stories talk about English walnuts, but there is a long tradition of hiding things or keeping them safe within a walnut. This speaks to some protective quality that walnuts have. One of the ways we might see this is using a visualization of walnut surrounding us to protect us. I can also see us using a whole walnut as a protective object to carry.
Walnut as an expeller. Just as walnut has its protective “within” quality, it also has a very strong “expelling” quality without. Walnut, through its very nature of producing juglone, expels things away. Walnut’s same medicinal qualities expel parasites from the body. We see this same expelling quality in the lore and magical lore of walnut. Given all of these parallels, it is reasonable to connect these to the spirit world: I would certainly want walnut as an ally on my side when there were things I wanted to be rid of, especially spirit activity. I’m sure there are many ways you can use walnut for this–what comes to mind most immediately is planting walnuts around a property, or taking a bit of walnut tincture to work to remove something unwanted (like sadness, depression, etc).
Walnut and gratitude. The long history of people “beating” walnuts to make them grow better and the problem of over-harvesting the walnut teaches us an important lesson in gratitude. We humans are so quick to take without consideration: the walnut reminds us of the important lesson of honoring the earth, harvesting that which is offered, but doing so in kindness, respect, and care for the living earth. I think these
