Herbs: Black Walnut Hull - Powder, Wild Crafted

Common Name: Black walnut
Latin Name: Juglans nigra
Origin: USA

Short Description:

Black Walnut Hull Powder has anti-fungal, antiseptic, astringent, and antiviral properties.

Excerpts from Practical Herbalism

As a rich source of iodine, black walnut (the hulls in particular) also gained much popularity as nourishment for the thyroid, especially in the interior parts of the country where sea vegetables were hard to come by.

Primary Constituents:

The active principle of the whole walnut tree, as well as of the nuts is nucin or juglone. The kernels contain oil, mucilage, albumin, mineral matter, cellulose, and water. Iodine is present in all usable parts of the black walnut, but the highest concentration is in the outer hulls of the nuts. Black walnut hull powder is also a significant source of potassium, magnesium, manganese, sulfur, copper, and silica. The nut meats are a rich source of essential fatty acids.

Precautions: Avoid internally during pregnancy.

Excerpts from Nutritional Herbology

Black walnut tones and helps heal inflamed tissues. It is also said to be effective in enhancing the elimination of various microbes from the bowel. Herbalists also recognize it as a thyroid stimulant since it is relatively rich in the trace mineral iodine.

Black walnut is typical of astringent plants. Its action is based on its tannin content. Tannins work topically to tone the body tissues they come in contact with. They function by precipitating free proteins which are generally present only in damaged and inflamed tissues. The term tannin comes from its use in tanning animal skins.
The tannins in black walnut are also thought to encourage the elimination of unwanted microbes in the colon. Herbalists believe that the acidic nature of tannins make life uncomfortable for the alkaline loving yeasts and microbes that can infect the bowel. Acid producing flora like lactobacillus acidophilus seems unaffected by the presence of tannins.

The content of iodine in black walnut is greater than most herbs. We have not been able to find any printed history of its use as an iodine supplement.

Contains astringent compounds that shrink inflamed tissues of the digestive system. It also contains bitter compounds that are antifungal and decrease the secretion of fluids in the digestive system.

Excerpts from The How to Herb Book

  • High in potassium, iodine, and manganese.
  • Muscle and nerve food; strengthens and builds tooth enamel.
  • Balances sugar levels, regulates body fluids.
  • Helps to burn up toxins which can then be carried out of the body by laxative herbs.
  • Parts used – leaves, bark, and nut hulls.

From Our Reading and/or Experience...

  • Avoid internally during pregnancy.
  • We use it in tincture combinations and capsules. Of course, it can be used in many other types of internal and external remedies, except as a tea as powders are not normally used in tea combinations.
  • Black walnut can be used to benefit anyone: men, women (avoid internally during pregnancy), children and animals.
  • It can be used as often as you would like, and in any way you choose.
  • As is the case with most herbs, black walnut should be stored in a dark, dry, and cool place.

Allergies and asthma
by Anonymous on Oct 17, 2014

I bought Black Walnut Hull as a dewormer for my goats. As an experiment, I made a drink in my vitamix, blending a tsp. of instant coffee, a tsp of cocoa, stevia, 1 tsp. black walnut hull and cream. During the same day, I drank a glass of water with bentonite clay softened in it.

To my great surprise, my suffering from allergies and asthma was greatly relieved! I was finally able to break my dependency on ADVAIR. I am now able to control my symptoms after 10 years of suffering! I have consistently experienced the same results now for the past year.

by Y Bulgaru on Mar 6, 2014

hello just wanted to know how many capsules is recommended daily?

    Re: question
    by Bulk Herb Store on Mar 17, 2014

    Unfortunately we do not provide dosage amounts because each person is different in their needs and health, and each herb is used differently for each health issue. I would recommend taking a look at our book, The Green Pharmacy. It is only $7.95 but is exhaustive on which herbs to use for a health issue and how much to use. Thanks!

Using for many reasons
by Kathy on Feb 22, 2014

I am planning on using Black Walnut hull for many reasons. One is for the iodine and have read that it can really help the thyroid gland. My elderly father will start soon on this product to hopefully help his bowel movements become regular.

I have one question though. I recently had some minor surgery on my face - removing some moles. I received both the Moncryl & Rapide dissolvable sutures, which I am either allergic to either one or both of them. In the meantime, I have had several infections and on an antibiotic. Would Black walnut hull help with this? And if so, what would be your recommendations. Thanks!

    Re: Using for many reasons
    by Bulk Herb Store on Feb 24, 2014

    I am not familiar with either of those sutures so I don't know what effect black walnut hull would have on it. Based on what I have read about black walnut, it may help with some infections such as yeast or candida. Our Detox+ would also be a great option for cleansing after having taken antibiotics to get rid of the toxins. You can also do a Google search for more info. on anti-inflammatory herbs to help with infections or check out the book "The Green Pharmacy Herbal Handbook" by James A. Duke Ph.D.

black walnut hull powder espresso
by Letha Hadady on Feb 13, 2014

Lately I am adding 1 tsp. black walnut hull powder and 1 heaping tsp. Turkish coffee and brewing it with 1 demitasse cup of water the traditional way using a small stainless steel pot. Tasty and effective, an energy boost that brightens the senses. This walnut hull espresso is deeply cleansing for yeast and long term parasites.

Taking Black a Walnut Powder Internally
by Connie on Feb 7, 2014

How is the best way to take black walnut powder internally, how much and how often?

    Re: Taking Black a Walnut Powder Internally
    by Bulk Herb Store on Feb 12, 2014

    Hello, I would recommend putting it into capsules for the best way to take it. The amount of powder you should take depends on why you are taking it and your personal health issues. I would recommend doing a simple Google search or check out our book Nutritional Herbology for dosage amounts for Black Walnut as well as a host of other herbs. Thanks!

Article on
by Eve on Feb 6, 2014

I've read contradictory reports on black walnut hull as far as the safety of taking it if you have nut allergies. Some reports say its safe and the other says its not. Is black walnut hull the only herb that can be used with wormwood and clove to get rid of parasites? Can you recommend or share more insight on black walnut hull and food allergies. Thanks

Adding this to the bentonite tooth paste?
by Andrea on Feb 3, 2014

Hello, I was wanting to add black walnut hull to the bentonite tooth paste recipe. Do you have a recommendation for how much to add? Maybe the same amount or half the amount of the bentonite? And at what point should it be added, should it be heated? Thanks so much for all you do! I love EVERY item I buy from BHS!

    Re: Adding this to the bentonite tooth paste?
    by Bulk Herb Store on Feb 4, 2014

    Hello, I would add about 4-8 Tbsp and add the Black Walnut Hull Powder along with the Bentonite clay at the end of the mix. Thanks!

Black walnut hull powder for yeast infection rash
by D on Jan 26, 2014

Can I mix this powder with coconut oil and bentonite clay to make a diaper cream to cure a baby yeast diaper rash ? Or maybe could I add it to my baby bath mix oil cream or green salve mix cream to cure it ?

    Re: Black walnut hull powder for yeast infection rash
    by Bulk Herb Store on Jan 31, 2014

    I would recommend trying Eden salve first on his rash and also for you to take Happy Gut to help your body process and deliver your food better. Thanks!

High Blood Pressure
by Christy Miller on Dec 29, 2013

Hi there

I have heard that this herb is good for blood pressure, Do you happen to know in what amount I should take this to help my blood pressure?

Thanks so much!


    Re: High Blood Pressure
    by Bulk Herb Store on Dec 30, 2013

    Hello, I couldn't find any information on how much to use but I would recommend starting with 1 tsp and working up from there, watching your blood pressure to see if you can tell a difference. If you have any questions you may also want to consult your doctor about dosages. Thanks!

by jon on Dec 6, 2013

how are the hulls ground? with stone? a machine? are they sterilized first? are they from walnuts picked off the ground, or plucked from a tree?

    Re: pulverization
    by Bulk Herb Store on Dec 11, 2013

    The Black Walnuts are ground by machine as they are produced by the tons. Our supplier does not sterilize them so that they will be only a raw natural product. Also as the Black Walnuts are produced by the mass there is probably a blending of being harvested from the ground and straight from trees. Thank you!

Hair color
by kat on Nov 13, 2013


Can this powder be used for covering grey hair? I read on many blogs that it provides very deep stain on almost anything. What is the procedure and do you ship worldwide?

    Re: Hair color
    by Bulk Herb Store on Nov 13, 2013

    We are not hair stylists so what ever research I did was online, but here is a great recipe for dying your hair using black walnut hull powder!
    For very dark hair, put 1/4 cup of Black Walnut Powder in a tea bag or cheesecloth bag and steep in 3 cups of water in a quart mason jar for at least 6 hours or overnight. Use as a rinse in the shower for hair and dry in the sun if possible. This will create VERY DARK hair, especially if you have dry or color treated hair. It will also provide the darkest coverage for grey hair. Repeat daily or as needed to darken and maintain dark shade.
    Use strong brewed black tea as a final rinse to darken any color hair. This is also nourishing for the hair and will provide a temporary darkening effect on most hair types. Repeat as necessary to get desired shade and sun-dry if possible.
    And, yes! We do ship all over the world!

Severe acne for my teenage son
by Marie on Nov 12, 2013

Would taking black walnut help to clear of acne?how much should he take. Would you also recommend the liver cleanse,burdock. I need some wisdom, things keep getting worse, we've tried the doctor with many medications, & antibiotics. I prefer natural, my son just wants something that will work.

    Re: Severe acne for my teenage son
    by Bulk Herb Store on Nov 12, 2013

    Yes, you can use Black Walnut Hull powder for your skin. For acne, the tincture is taken both internally and sometimes apply diluted externally as a skin treatment. If applying it to your skin, it would once again be best to test it first for your own sensitivity.
    A liver cleanse would be a great place to start as far as cleansing your body of toxins that could be causing acne. Burdock root is a great antiseptic as well.

Black Walnut for hair fall?
by Kelley on Nov 3, 2013

Wondering your thoughts on making a paste with nettle for severe hair fall. I believe it is a thyroid issue that has given me a very dry scalp and possibly a scalp I will take it internally as well for the thyroid.

With every shower for the past month I leave a whole heaping handful in the shower- the hair is too loosely attached at the scalp--it is frightening and I dread it ... and it is not slowing. Any other ideas would be helpful.

    Re: Black Walnut for hair fall?
    by Bulk Herb Store on Nov 8, 2013

    Hello! I haven't heard much on black walnut for hair. Nettle is great because it has been included in hair tonics for centuries due to its purported ability to stimulate hair growth! I would also recommend Horsetail Shavegrass as well. It has been used to strengthen nails and hair follicles. Here is also a recipe we have for hair.

    Rapunzel Hair Mix

    1 Tablespoon Butcher’s Broom Root Powder (optional)
    1 Tablespoon Oatstraw Powder
    1 Tablespoon Nettle Leaf Powder
    2 Tablespoons Diatomaceous Earth Powder
    1 Kelp Powder Capsule a Day

    Combine the first 4 herbs until thoroughly mixed, and add 1-2 tablespoons to your daily smoothie or juice. I recommend encapsulating the Kelp Powder and taking 1-3 capsules a day.

similar to walnut shell powder?
by KC on Sep 27, 2013


Would this work well for a face scrub? Walnut SHELL powder is harder to find.. I read that this is used for detox. Is this okay to use topically or internally while nursing? Thanks

    Re: similar to walnut shell powder?
    by Bulk Herb Store on Sep 30, 2013

    It can be used in many types of internal and external remedies, except as a tea as powders are not normally used in tea combinations.
    Black walnut can be used to benefit anyone: men, women (avoid internally during pregnancy). If used as a a face scrub, you would be fine. While nursing, as long as it isn't a large amount, it should be ok.

by korena on Sep 11, 2013

Hi, 2 questions about black walnut hull. Can walnut hull be taken orally to help stimulate your thyroid? If so how much is considered a dosage? To dye the skin can you mix black walnut hull to boiling water? (I do a lot of bodybuilders for weight lifting competitions) Thank you for any information!!

    Re: palatable?
    by Bulk Herb Store on Sep 12, 2013

    From what i have read, yes it can. As far as dosages, we cannot give you that answer. We are not Medical professionals.
    I have dying hair with black walnut by simmering in hit water but I'm not sure about the skin. Thanks!

Green black walnut powder
by Eunice Unruh on Aug 12, 2013

To be effective for deparasiting, I understand the balck walnut has to be from the green covering / shell of the nut. The powder you sell is it from the the green black walnut shell?

    Re: Green black walnut powder
    by Bulk Herb store on Aug 14, 2013

    Yes, the powder is ground from the hull covering the walnut. Thanks!

Parasites for young kids
by Michelle W. on Jul 28, 2013

My 3 and 4 year olds have Blastocyctis (a parasite). I was wondering what you be the best way to administer this...I was thinking tincture. And how much to be effective. I was also thinking Diatomaceous Earth for them as well. Any thoughts on this?? Thanks so much, and thanks for all you do. I have learned so much from you and your family. You have taught me so much, I cannot thank you enough!

    Re: Parasites for young kids
    by Bulk Herb Store on Aug 2, 2013

    You can make this as a tincture. Check out our Bulk Herb Store Articles. We have a page called, "You've got worms." It has a recipe for adults and children to get rid of parasites. Thanks!

How do I make a tincture
by Mel on Jun 30, 2013

My son has been having similar issues to the ones mentioned already and I have no idea about tinctures. How would I make one.
Also If using as a worm treatment are capsules the best form to take?
Any advice is much appreciated. :)

    Re: How do I make a tincture
    by Bulk Herb Store on Aug 2, 2013

    Go to the How-To page on our sight for detailed instructions on how to make a tincture. And it would be your preference on taking the wormwood treatment. Thanks!

Taken while pregnant
by Dawn on Jun 24, 2013

Hi, I found out a week ago that I was expecting again and am a little nervous, because I have been using black walnut hull powder with my toothpaste when I brush my teeth. I obviously will stop now, but am wondering why you are advised to avoid this herb while pregnant? Do I have anything to worry about?

    Re: Taken while pregnant
    by Bulk Herb Store on Jul 12, 2013

    No, you are fine! We say avoid internally during pregnancy but as long as your not swallowing, you can continue using it in your toothpaste. Thank you!

Good in smoothies?
by Michelle on Jun 23, 2013

Would the Black Walnut Hull Powder be palatable in smoothies?

    Re: Good in smoothies?
    by Bulk Herb Store on Jul 10, 2013

    I have never tried it but I'm guessing it would be hard to mask completely as it is a rather strong herb.

powder for salves
by Jen Maddocks on May 6, 2013

I used black walnut hull powder(from capsules) along with several herbs to make a salve. I strained it first with cheese cloth and then old clean t-shirt. The salve came out fine and smooth. You can order hulls from Pacific Botanicals for tincture. Great for building enamel as decribed in Be Your Own Doctor.

black walnut
by Barb on Apr 23, 2013

I used to make a salve out of black walnut husk,cinnamon and clove. It was a great anti fungal for my feet.Unable to find husk-the inner layer of the bark-. I'm curious if this product would be a suitable substitute.I made an oil of the herbs and added beeswax to thicken.

    Re: black walnut
    by Bulk Herb Store on May 1, 2013

    It is not going to work as well to use a powder when infusing with oil as it will be harder to strain out all the grits but you can try it!

GAIL, I need your advice
by lori on Apr 21, 2013

My son has a similar rash, going on for about a year and is has recently gotten to the point we are considering black walnut hull. Can you tell me how much you used in your dosage?

Tincture vs powder
by Nicole on Mar 26, 2013

When doing an intestinal cleanse for parasites, would it be sufficient to use the hull powder vs the tincture? I have a candida issue and I'm not supposed to consume alcohol. If so, what would be your recommended dosage for the powder, for one drop of the tincture?

Thank you for your time

    Re: Tincture vs powder
    by Bulk Herb Store on Apr 30, 2013

    Hello! We have the full directions for using capsules if you would like to contact us at Bulk Herb Store for them. Thank you!

toenail fungus
by phyllis on Mar 24, 2013

I was wondering can black walnut hull powder assist in eliminating toenail fungus if used with tea tree oil?

    Re: toenail fungus
    by Bulk Herb Store on Apr 26, 2013

    It is an anti-fungal so I would definitely count it worth a try!

Uses for teeth
by Anonymous on Mar 23, 2013

Has anyone used this for strengthening tooth enamel? If so, in what form did you use it?

    Re: Uses for teeth
    by Bulk Herb Store on Apr 26, 2013

    In the Be Your Own Doctor book, it is recommended taking in tea or tincture form to remineralize tooth enamel.

Black walnut hull powder
by Andrea on Jan 14, 2013

I've been taking the black walnut hull - powder internally for about a week. I stopped nursing my youngest son about 15 months ago and I continued to have problems with my nipples not healing after nursing. After one week of taking this they are completely healed.

What is the minumium age
by Robert on Dec 3, 2012

I was curious about this herb, if you believe it to be safe for young children around 14 months or so.

    Re: What is the minumium age
    by Bulk Herb Store on Mar 22, 2013

    We do not recommend giving it to children that young. I would suggest seeking advise from a professional herbalist or practitioner about what age it is appropriate for.

by Kathy Oakes on Sep 29, 2012

I am very familiar with making tinctures from fresh and dried herbs. How would you go about doing a tincture from powder? thanks!

    Re: Tincture...
    by Bulk Herb Store on Mar 15, 2013

    We don't recommend using powders for tinctures because they are not convenient but you would use them the same as dried cut herbs.

Yeast infection or Parasites
by Gayla C. on Jul 10, 2008

I was reading your testimonies and came across one that referred to a remedy "for my 3 year-old daughter which actually tames an itchy, red, dry rash on her hands that has plagued her for two years."

This sounds just like my daughter's problem several years ago! We discovered that the rash was caused by a yeast infection or a parasite. We treated her (after getting no help from a doctor) with black walnut. We used leaves and hull and they both work. She took it internally, twice a day for about 2 weeks. She had immediate results after the first tea, so I made it into a tincture. I treated her again a month later because of a recurrence, which makes me think it was a parasite, and we never had another problem. I hope the mother of this child reads this and tries in for her daughter. It was a terribly painful rash with such an easy remedy. It made me a true believer.

Thank you for all your products and the information you provide on your website. It has all been truly helpful.

Please, take a moment and comment on this product.
