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. This Black Walnut was harvested when the hulls were still green, which is the most nutrient rich and effective stage of Black Walnut hulls to be harvested for optimum health benefits.

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

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.

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!

    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!

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!

    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!

    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.

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.
