Black Walnut Herb Good for digestion parasite removal hair dye Black Walnut Hull Herb Profile

Black Walnut Hull or Juglans Nigra is, just as it sounds, the hull of the black walnut tree. The Black Walnut tree grows in the eastern US and parts of Canada, and while easy to grow, it is not plentiful.

What is Black Walnut?

Black Walnut has been used in herbal medicine for thousands of years. It has been used throughout history for treatment of intestinal problems, snakebites, open wounds, ulcers, scurvy, and as one of the most effective laxatives available. Because of its dark color, the outer hull is also used as a dye and was used in brown hair dye until the early 1900s. Black walnut is a good source of beta-carotene, acids, calcium, iron, magnesium, manganese, phosphorus, potassium, selenium, silicon, zinc, tannin, B-vitamins, and vitamin C.

Today, black walnut hulls are used to help with many conditions. It is known to be a gentle and effective laxative. Black walnut is known as an effective anti-viral and is used to fix warts, which are caused by viruses. Black walnut is an anti-fungus and has been used to fight herpes, cold sores, athlete’s foot, and Candida. It has been used as an antiseptic to combat illness like sexually transmitted infections and malaria and can be used to treat acne.

How it is used:

According to scientific labs:

  • Black Walnut Hull may help to lower blood pressure and serum cholesterol levels and is believed to burn up toxins and fatty materials while balancing blood sugar levels.
  • The tannins in Black Walnut Hull (and leaves) possess an astringent quality that is thought to shrink the sweat glands and reduce excessive sweating.  The herb is said to help control menorrhagia, the excessive loss of blood during periods. It is also used to control diarrhea.
  • Black Walnut Hull is considered a tonic that aids digestion and the intestinal system. It helps to relieve colic, heartburn and flatulence.  As a cholagogue, Black Walnut stimulates the flow of bile into the intestines and is thought to ease bilious colic and pain in the spleen.”

Perhaps Black Walnut’s most well-known property is its ability to fight intestinal parasites. It is a well documented vermifuge that is effective at helping the body rid itself of parasites. As a laxative, it expels parasites as part of its cleansing of the body and the high tannin and juglone content is thought to oxygenate the blood and kill parasites. Black walnut is effective against pinworm, ringworm, tapeworm, and other intestinal parasites.

From Mountain Rose Herbs: “Black walnut hulls contain juglone, a chemical that is antibacterial, antiviral, antiparasitic, and a fungicide. As a skin wash, black walnut hulls are used to treat ringworm and yeast infections of the skin. Taken internally, black walnut hulls are used to treat intestinal worms.”

Notes:

“Black walnut hulls are safe for occasional use of up to 2 weeks at a time, but black walnut heartwood is not. Avoid herbal remedies which contain heartwood.” (from Mountain Rose Herbs) Black walnut is an extremely potent remedy that should be used under the care of a holistic health professional. Should not be used during pregnancy or illness. Consult your doctor if you have any condition that is severe or lasts longer than a few days.

    Would this be a good herb to use for shingles? What would be the best way to go about using it? externally or internally?

    • Kim Kraus says

      If you all REALLY WANT to know what it can be used for: Black Walnut tinctures and parasites or infections or diseases related to overintoxication by parasitic-wastes, ie.shingles, arthritis etc.
      are explained in a book my Mother used to prolong her life for 8 years called:
      “The Cure for All Diseases” Hulga Raeger Clarke I think the author’s name is spelled. My Dad still uses her methods today and he is 82!! (Zapping and Tincture cleanses of the organs)
      Warning: must have self-discipline to use her very long and drawn-out cleanses are for REALLY serious about their health people. Not for the partially-committed lets say.

      • HK says

        While Hulda Clarke did have a legitimate educational background, she also had some wack-job ideas on natural health and eventually fled the country to Mexico so that she could be out of the reach of the US government after they began to investigate her and the safety of her “zappers” amongst other things.

        We can all live longer lives if we begin to take our health seriously and work to keep ourselves healthier and well. Wellness is not some mysterious goal to be achieved. Our society and capitalistic environment keep us sick and unhealthy because sickness is an economy and makes lots of people rich. Natural health gurus with lots of products for sale can also take advantage of people looking for health and wellness. Research Hulda Clarke before following her protocols, she is not all she’s cracked up to be.

    My 4 year old has so many warts on his hands. We got rid of them with raw apple cider vinegar, but they are coming back. How would I use this internally to get rid of them for good?

    • Mackenzie says

      I know you can use them externally to get rid of warts. Pick a black walnut while it is still green, cut it open and rub the green meat over the wart. Do this twice a day for about 3 days. This will stain your skin green, but not to worry, it will wash away. Be careful of clothing as I have not figured out how to get rid of that stain. I have gotten rid of my warts in 3 days doing this.

      • April Grow says

        Thank you! I will have to wait until this summer when I can get some green black walnuts. Does it hurt the skin around it? Does it work on all types of warts?

        • Mackenzie says

          It just stains the skin for a little while. I have used it on common warts and ringworm. Both still only took about 3 days to get rid of completely.

    • Annina Plummer says

      Sally, have you learned if you can eat the green hull raw and if that helps? I would really like to know. Thanks!!!

    • Dr. David says

      Black Walnut will not reverse tooth decay as it has nothing to do with calcium utilization in the body. To get prevent or reverse tooth decay, it is essential that one take Vitamin D3, Vitamin A, and Vitamin K2 (mk-7 type). There are 2 types of vitamin K.. the usual and the K2.. the usual K is what body uses for blood coagulation to form scab to heal a cut… K2 is what determines where calcium will go in the body. K2 is what activates the proteins in the bone that capture and bind calcium. Notice, Vitamins A, D, and K2 are ALL fat soluble vitamins. We use to get vitamin K2 naturally from the milk of GREEN GRASS fed cows. Cows are essentially penned and grain fed now so that the milk does not contain K2. The only primary source of K@ is a Japanese fermented soy bean dish called Natto. Western people cannot usually stomach smell, taste, or texture. So, supplementation is necessary or we are GUARANTEED to be deficient.

    • Kathleen says

      Herbalist Steven Horne once quoted another herbalist (can’t remember who exactly) who used black walnut powder on cavities. I guess he packed the cavity area with the powder and left it there for some time, repeating until completely healed.

      The action has more to do with the anticeptic nature of BWH than anything else (cavities are really just tooth infections) but the calcium content and thyroid support BWH provides no doubt aids in this.

      Many people use powdered BWH on a toothbrush for prevention and good oral hygiene. Especially good for loose or inflamed gums.

  3. Corey Hagemann says

    I’m not sure where this is not plentiful. You can’t walk very far where I live (northern Illinois) in the fall without stepping on fallen walnuts, hull intact.

  4. Jenny says

    My 18 month old has had ringworm for 6-8 weeks now. I have been treating it with OTC anti-fungal creams per his pediatrician. I really want to try the black walnut. How do I apply it externally? Tincture? Powder?

  5. Ann Marie says

    Hello,

    I am having terrible issues with chemical sensitivities. I am 54, have white/grey chemically dyed hair and am very interested in using black walnut to dye away the grey. However, I am hesitant because I read on Web MD that black walnut applied topically may cause tongue cancer. I have great respect for your research abilities and hope you can allay my fears in using black walnut hull hair dye for long-term use.

    Kind Regards…

  6. Ashley says

    I am pregnant and want to keep my greys covered without putting harsh chemicals on my head. Is it safe to use just for that purpose? I don’t want to take it internally.

    • HK says

      use Henna hair dye instead – Rainbow Henna – lasts about 6 weeks – cheap, natural and long lasting – use two tones to get better highlights.

  7. Billa says

    Would you provide me more details on how i can use black walnut as “Natural Hair Dye”. Currently, i use henna. Are there any side effects? If i use both simultaneously?

    Thanks,
    Billa

    Wondering if you think Diatomaesous Earth is the route to take to help with my 12 year old daughter. She suffers from sleep distrubances, hormone imbalance, acne, fatigue, scalp irritation, & constipation. She is gluten free and dairy free already. She is a very active USA swimmer so sleep is so curcial among many things. I’d like to add DE to her morning coconut milk smoothie. She currently takes omega swirl, magnesium and probiotics.

    Thanks for any feedback.

    • HK says

      always be extra cautious when using D.E. – if you are using it in powder form you need to be careful to not breathe it in. it can damage the lungs.

    • Kitty says

      Sounds like she has Candida overgrowth; Diatomaceous earth will help. Also try a yeast and parasite cleanse. Some of my favorite brands for this are Now Foods’ Wormwood tincture, Kroeger Wormwood combination, Dr. Hulda Clark’s Parasite Cleanse Kit, and Candizyme.

    • Linnette says

      May I recommend a two stage process for completely covering white hair in one go.
      I discovered this from a woman who sources the best quality henna powder and indigo powder check her Uk site called Renaissance Henna. First do the henna, then do the indigo on top. Everyone is always wondering why my hair looks so shiny and strong.

    IS BLACK WALNUT POWDER SAFE FOR PETS TO INGEST ? YORKIE & AUSTRALIAN HEALER DOGS, and STRAY CAT – TO BE EXACT.

    • Jeni says

      My dog thinks black walnuts in their husks are balls and is constantly dropping them at my feet to throw. Twice I’ve seen him accidently swallowed some of the husks, and then vomited for a little while. I’m sure he gets small bits ingested on a regular basis during the months there are walnuts, and is otherwise healthy.
      Not sure if this helps much!

  11. Charlene says

    Just wanted to know, is it safe to ingest black walnut extract diluted in cold drinks or smoothies? I suffer from digestive issues since the gall bladder removal. I have gained alot of weight in my mid-section and often enough I feel bloated. Can it treat yeast overgrowths due to high blood sugar levels? I have acid reflux and read that this extract can help with digestive issues. Is it safe to use the extract topically? I could use some sound advise. Thanks

  12. May says

    Just wondering if black walnut in capsule form can be taken during early pregnancy. If not recommended why? What else can be used treat pinworm safely during early pregnancy?

  13. Pam says

    “Milk” from a milkweed will also get rid of warts. It only takes a few times ; leave the milk on as long as you’re able.
    Grey hair is a copper deficiency.
    When using DE, make sure you’re using food grade.
    Thanks for the good info on your site!

    My male cat recently had loose stools and after reading about the benefits of Black Walnut Hulls. I purchased and used six drops per one cup of water, which I gave him a teaspoon three times a day for three days. His stool is back to normal and a happier kitty!

    Regards,

    I made black walnut tincture for the fist time, but i’m not sure if it turned out right, it smells kind of strange and when I opened the jar for the first time after having it sitting in a dark room for a couple of weeks it fizzed like when you open a soda pop, is this normal?

  16. Alma says

    Black walnut in liquid or powder form is quite effective to use for killing parasites in cats, dogs & humans. It is used as a natural preventative for heartworms in dogs, & also as a natural treatment/remedy, should your dog have already contracted them.
    Black walnut is very powerful; a tiny amount goes a long way. For example, just two drops of the liquid on my cat’s canned food for five days eradicated his tapeworms, whereas the expensive vet medication I had given him previously did not.
