8 Black Walnut Benefits for Skin Conditions, Candida, Warts and More

Antifungal black walnutsBlack walnuts are a superfood with many beneficial properties. They have been used by traditional cultures for centuries for a wide variety of ailments.

Modern scientific research is only just starting to uncover some of the unique nutritional elements in these potent nuts.

Here are 8 different ways that eating black walnuts, or using an extract of the green hulls, can benefit your wellness and wellbeing.

8 Beneficial Effects of Black Walnuts

1. Natural Remedy for Skin Conditions

Black walnut benefits include treating skin problems like acne, eczema and psoriasis.

For acne an extract of the green hulls, like this potent wildcrafted one, is taken both internally and applied diluted externally as a skin treatment.

If applying it to your skin, it’s important to patch test it first for your own sensitivity.

To do this, mix a few drops in warm water and dab a small area in an inconspicuous part of your face with a cotton ball. Leave it for an hour or two to see if you have any reaction before using it on the rest of your face.

There are also many reports online of success with taking black walnut extract internally for eczema and psoriasis. Alcohol-based tinctures would be too harsh to apply topically for these skin conditions though.

Black walnut kernels are also rich in antioxidant polyphenols to protect your skin from free radical damage and improve your complexion.

2. Treatment for Warts

Warts are growths on the skin caused by a viral infection. Regular application of green black walnut hull extract is often reported to make warts shrivel up and die.

It’s applied undiluted directly to the wart daily and covered with tape or a band-aid.

Results can take several weeks but many people find their warts start to shrink and eventually die and fall off with this treatment.

There have also been cases discussed in online forums of multiple warts shrinking and disappearing after regularly taking a strong extract like this.

3. Fights Parasites

Black walnuts, and in particular their outer hulls that are harvested green, are a well known vermifuge in herbal traditions. They are considered a premier treatment for pinworms, tapeworms, hookworms and other intestinal parasites.

4. Controls Candida

Like intestinal worms, candida overgrowth is another common, yet rarely diagnosed and debilitating problem affecting many people.

Most people have some candida albicans yeast in their digestive systems. Problems start though when intestinal conditions deteriorate with a diet high in simple sugars, prolonged stress and especially antibiotic use.

Intestinal candidiasis is an overgrowth of the candida fungus, which weakens the walls of your intestines and can release toxins into your bloodstream.

This plays havoc with your immune system and can manifest in a whole range of baffling symptoms which can be very difficult for a GP to diagnose.

Studies on compounds found in black walnut extract have shown it to be as effective against candida as commercial antifungal treatments.

Naphthoquinone juglone, high levels of astringent tannins and other compounds in black walnut treatments may change the intestinal environment to make it unfavorable for the candida albicans fungus.

5. Antifungal Effects

These same antifungal properties make this potent green hull tincture a popular treatment for athlete’s foot, ringworm, jock itch and other fungal infections of the skin.

To treat these fungal skin conditions the black walnut tincture can be applied externally to the affected areas and is often reported in online forums as highly effective.

Always patch test any preparations like this on the skin of your inner arm for several hours before using them to test for allergic reaction.

6. Stops Sweating

In one of the more unusual benefits of black walnut, it is known to help reduce excessive sweating.

The high levels of astringent tannins contained in the hulls have an effect on overactive sweat glands and decrease the amount of sweat they produce.Green Hull of Black Walnut on Tree

7. Improves Digestion

Alongside its powerful anti-parasitic and anti-fungal properties for your gastrointestinal tract, black walnuts have other beneficial effects on your digestive system.

Black walnut hull is said to tone and heal inflamed intestinal tissue, as well as improving the environment of the digestive tract for more effective assimilation and elimination. It’s for this reason that the tincture is considered a treatment for both constipation and diarrhea.

8. Treats a Sore Throat

You can gargle with black walnut tincture diluted in water to treat a sore throat, tonsillitis and mouth sores. Once again, the astringent tannins and naturally antiseptic iodine provide the beneficial effects.

Eating Black Walnuts

While English walnuts are a very healthy food that can be eaten in moderation every day, fresh black walnuts like these appear to be a more high-powered version. They are better viewed as an occasional treatment, rather than a snack food to be eaten often.

I’d appreciate hearing about your experiences with eating black walnuts or using the green hull extracts in the comments below if you give them a try for yourself.

Next is a deeper look at how to use black walnut hulls for parasites and intestinal worms.

I am curious to know how one can transition their diets while poor simultaneosly??? It is as though a “choice” is only given to those who can PAY for it… generally you would think that “natural” would equate free, a total opposite of the synthetic so-called “european”/anglo-saxon capitalist patriarchal supremacist world. Seems the attacks upon nature in ALL its forms is directly correlated to attacks imposed upon creatures, whereby they are “gangstered” or coerced into accepting synthetics vs. nature= a type of SELF reliance INDEPENDENT of artificially constructed food producers, etc. HOW can a poor person incline their personal health? I live in Nyc. Wholefoods, etc., is HIGH, regular stores don’t provide, what can I do???

Jim Dillan

It’s a valid point Siafa but addressing it would probably take a 5000 word article minimum and still probably not scratch the surface.

The short answer is, yes you generally do need to contribute more of your money to healthy products as the cheapest foods will often end up costing you more in the long run to your health. More fruit and vegetables, free range eggs and ditching processed meats, high carbohydrate snacks and junk food is a good start.

Back before the invent of mass processed foods the average family contributed a much higher percentage of their income to putting good food on the table and much less to electronics, cigarettes, alcohol and other ‘luxuries’. I don’t know your own situation so this isn’t aimed at you in any way, just a general comment on societies priorities these days and the high prevalence of diseases that result.


If you can find your way to purchase a juicer – thrift store even – you could juice. I have heard of people who purchase dated fruit from the market and juice that with great benefit. I healed my daughter’s Crohn’s disease thru juicing. A vegetarian lifestyle is the least expensive of all. When your body becomes more alkaline and better nourished it takes much less food to satisfy your appetite. This way might appear to be more expensive at first, but is not so in the long run – especially when you consider reduced medical costs.


I know the original question was posted over a year ago, but researching online shows there are ‘recipes’ to make your own tincture from black walnut hulls. Maybe take a trip to a large rural park or something to find black walnuts that are just dropping to the ground for the squirrels?!
Black walnut trees grow in about any where there are ‘forests’.
There are ‘forager’ type websites that may help!
I have about 8 black walnut trees in my large yard… but I live in Kansas so wouldn’t be much help in letting you help yourself…
Good luck!

Hi Jenifer and thanks for your comments. If you could make the black walnut tincture strong enough this would indeed be a good option.

All the best.

Moving to the mid west would be a good option for NYC dweller we have cleaner air cheaper food and black walnuts everywhere.


I have had psoriasis for 20 years. For the past two years I have struggled with severe psoriasis of the palms of my hands. It was so severe my palms would develop painful cracks in them. Recently I had shelled the husks off black walnuts and unknowingly stained my hands from working with these nuts. Within two weeks my hands completely cleared up! I couldn’t believe it. I have now purchased a tincture of black walnut and mixed it with Vaseline. I am applying it at bedtime covering my hands with cotton gloves. It is my hope that this continues to keep it at bay. I have also done internet searches and was surprised to learn black walnut is used to treat many skin conditions. I am excited about this inadvertent discovery.

Jim Dillan

Hi Ruth and thanks for sharing that.

Black walnut is known to be good for skin conditions internally though I haven’t read much about using it for psoriasis externally. This is great that you’ve got such a positive result with it. I wonder whether mixing it with avocado oil, also said to be good for psoriasis, may be even more effective than vaseline.

All the best,



i think you missed one good point….
a gargle with black walnut extract and water; taken 3 times a day, can actually cure cavities !!!!!!!!!!!!!!!!!!!!! plus help with tooth decay and as a added goody– a teeth whitener!!!!!

Jim Dillan

Hi Heidi and thanks for the extra information.

All the best,

I don’t know the original cause of my problem, but after reading your article, I think that my tea-with-sugar habit combined with the chlorinated water caused yeast growth, which caused cystic acne all over my body. Before that, I had psoriasis, which I thought was just annoying, but as it persisted, it became a real problem. I have tried everything to get rid of my acne outbreaks for the last 6 years. (homeopathy, diet, etc.) All the doctors recommended were antibiotics–repeatedly. Eventually, I just said no to drugs.
I read about black walnut last year, so when I went to Canada to my mother’s house where we have beautiful, large black walnut trees, I picked up the leaves and made a tincture. Within 8 days, my acne has gone from a major-scary-face to a minor problem! And I only got the leaves! This year, I am going back and I hope to collect some hulls. .
I am going to put the tincture in coconut oil to keep on hand for any recurrences. Thank you for the tip on warts and skin application. Based on my experience, black walnut is the number one cure for cystic acne.


How can black walnut extract whiten teeth when it stains everything in comes into contact with black? Not knowing any better, my kindergartener was playing with the black walnuts that had fallen to the ground at the end of the summer right before school started. His fingers, fingernails, cuticles where he touched the walnuts and the meat of the husks, were stained black! No matter how much he washed and scrubbed and we tried different soaps, dish soap plus baking soda, we could not get all the black stuff off. It took nearly 3-4 weeks, the amount of time for new fresh skin to grow, for the skin to go completely back to its normal color.


I’m from NYC but live in richmond va now and also on a low income… However, you could buy one thing at a time and u would be surprise how what you could accumulate… Also it’s not that expensive.. They have herb shops all over NYC(Really every city)you could go to wholefoods(expensive)… I think I paid $10 for black walnut oil… N honestly I think NYC is better stores mom n pop shops r better then the fanasty ones

Jim Dillan

Hi Allison and thanks for sharing this. It just goes to show how powerful natural treatments like black walnut can be. The leaves do have some of the same compounds but usually the green hulls are used as they are considered much more powerful, particularly for yeast which is often the underlying cause of many health problems. Making up a black walnut tincture for future use is a good idea.

All the best,



This is Truly a Blessing!! Thank You!! Bless You! ~?

Hi Maria,

I haven’t tried black walnut for teeth whitening and believe that was another commenter that mentioned this. The iodine content is known to stain skin and clothes.

All the best,




I do not know as to check up yours tinctures of a black nut on iod, but
i know how easily to check up on juglone.
Take any quantity of colourless vegetable oil and mix it
with the same quantity tincture. In some minutes a liquid to be divided
and the oil will be painted in yellow colour. Than the yellow colour more juglone by that by those.


I am trying black walnuts for the first time and am having a hard time finding a nut cracker in stores where I live. Also, do I save the yellow outside covering or throw it away and just save the walnut? KG in Montana

Jim Dillan

Thanks for the info on juglone Nikolay. I think this would be a good way to test for potency.

All the best,

Hi Kathy,

You can use the outer green hull to make your own tincture for treating parasites. This video has some instructions https://www.youtube.com/watch?v=DidjU0zwRcA Alternatively you can use the prepared tinctures or capsules in this page https://superfoodprofiles.com/black-walnut-parasites-intestinal-worms

I’m excited for maybe having a light at the end of the tunnel


I’m not sure about your using vaseline with the black walnut tincture. You might want to make sure it’s not made out of petrolem. Coconut oil or olive oil aregreat carrier oils as well and all natural.

Jim Dillan

Hi Christopher and thank you for sharing your experience with black walnuts and method of using them. This sounds great if you have access to fresh black walnuts.

All the best,


christopher riley

let the nut dry to brown. Crush up the skin to powder. Drink the skin with hot water. The nut on the inside of the shell is nothing more than a nut.

Black walnuts are as free as air. Find a black walnut tree and pick up the walnuts in the fall when they drop. Almost no one who owns the trees will deny you some walnuts.


Also Black walnut is used to treat parasitic worm infections, And certain other infections including diphtheria and syphilis. It is also used for leukemia. Also I Read Before Few month ago Some people use black walnut as a gargle, apply it to the scalp as hair dye, or put it on the skin to treat wounds I Don’t know what is true?, But Its Amazing

Jim Dillan
