Black Walnut for Food and Supplies - 4

You’ll find tall and stately black walnut trees (and their cousin the butternut walnut) growing wild throughout much of the central and eastern U.S. They’re particularly noticeable in the fall when their green-brown-black, tennis-ball size nuts begin littering the ground. The rough round husks turn from green to a very dark brown as they lay on the ground in autumn. These native trees have provided people with food, medicine, dye, and beautiful wood for centuries. Here are just a few of the valuable things that these trees can deliver.

Food
The nut’s multi-color husk is deceptively large, compared to the small amount of meat you’ll pick out the inner nutshell. Still, it’s a worthwhile endeavor because black walnut nutmeat is second only to hickory in caloric value from wild plants. One ounce of the rich tasting nutmeat contains 173 calories, along with a fair bit of protein, magnesium, phosphorus, copper, and manganese. Wild animals might even let you have some, primarily because they don’t like to chew through those thick, bitter husks. This means that there can be black walnuts on the ground well into winter. Our family has always chucked the whole walnuts onto the driveway to let car tires crack the husks off. After a little weathering, the inner nutshell is exposed and ready to crack without being so messy.  

Medicines and Dye
The green husks of walnuts have many uses in folk medicine. One tablespoon of the dried green husk material in one cup of hot water will make a horrible tasting, yet parasite expelling tea. Sip on one cup over the course of a day and repeat this for seven days. The fresh husks have been used as a substitute for iodine tincture as an antiseptic on small cuts and wounds, and it even stains the skin like iodine.

To make a dye, crush a gallon of husks and soak them in a gallon of hot water. If the husks were still green, you’ll end up with a bucket of yellowish-brown dye. If the husks have already turned black, your dye will be dark brown. I have a buddy who made his own camo t-shirts by tie dying some regular white cotton T’s in black walnut dye. They turned out great, revealing a very unique camouflage pattern in a nice shade of cocoa powder brown.

Wood and Weather Predicting?

Although it is terrible firewood, burning poorly and creating great volumes of ash, walnut wood has been prized for furniture and other carpentry projects. There’s a sharp contrast between the white sapwood on the trunk’s exterior, and the chocolate brown heart wood that makes up the majority of the tree.

This is a new one for me, but an old timer I spoke with yesterday indicated that walnuts predict the upcoming winter weather. Bigger walnuts indicate that a rough winter is impending, while smaller walnuts indicate a mild winter to come. With the generous size of this fall’s walnut crop (plus the almanac prediction), it may be wise to cut a little more firewood while the weather is good — just make sure it’s not walnut wood.

Do you have another use for black walnut or another way to get the husks off?  Let’s hear it in the comments.

I would not recommend this as it is probably illegal, but the green nuts can be mashed up, placed in a tow sack, and tossed into a pond. The fish will be stupefied and rise to the surface for a short time, where they can be scooped up or snagged. I know this works because a young friend of mine did it in a private pond. He snagged a couple dozen of large buffalo fish, which he sold in town for some spending money.

When I was a kid, we had a large Walnut tree in our back yard. My Granny, a Registered Nurse who raised me, would take the walnuts when the husks were green and bruise a spot on the hull enough that it was a little bit juicy. She would rub the bruised area of the walnut onto our skin, wherever we had "ringworm". This is simply an area of skin where a fungus would grow that looked like little round circles, sometimes large circles. The area where she would rub the walnut hull would immediately turn brown. In a day or two, this ringworm fungus would disappear and not come back. I never tried this on any other fungal infection, mostly because ringworm was the only fungal infection I ever got, but it sure killed ringworm.
A word about my Granny. She was what came to be called a Pioneer Nurse right after graduating nursing school at the age of seventeen. She rode horses, mules, carriages and any other form of transportation that existed all through the coal country of West Virginia, Virginia and Kentucky as a nurse practitioner and midwife and was often the only medical care the people in these areas ever had. She told me that the folk medicine she learned during her time there meant more to her than what she learned in nursing school. If anyone who reads my comment knows anything about the Pioneer Nurses, please email me at crissmorgan@wildblue,net.

Apparently our squirrels haven't heard that wild animals don't like to chew through the thick, bitter husks, because they love 'em.

What's your take on Walnut Fly larvae infestations. My small property has walnuts all along the borders, but the couple of years when I've tried to claim some for use they were almost universally covered in walnut fly maggots and their droppings. I've read that they droppings can permeate the hard shells to the meat of the nut, and so I've left them alone (the maggots themselves are in the outer casing). Any advice on dealing with that?
