Black walnut benefits

Black Walnut Hulls

Black Walnut Benefits & Uses

Besides being one of the most effective herbal laxative remedies and also being rich in Vitamin C, black walnut hulls have a long history in herbal medicine. Pliny the Elder, the Roman naturalist, talked about their healing power in the first century A.D. Seventeenth-century herbalist Nicholas Culpeper prescribed walnut to draw poisonous venom from snake and spider bites. It was the Native Americans, however, who first used black walnut hulls as a laxative and as a treatment for eliminating parasites in the intestine. This use, as a laxative, is how it is most commonly implemented today.

One of the key active components of black walnut hull is juglone. Juglone exerts its effect by inhibiting certain enzymes needed for metabolic function. It is highly toxic to many insect herbivores (it is often used by organic gardeners for pest control), and studies have shown that it can expel parasitic worms from the body.[1] Black walnut is reported to be effective against pinworm, ringworm, tapeworm, and other intestinal parasites. While there are very few scientific studies on black walnut hulls, the ones that exist are very interesting and suggestive. 

Bactericidal and Virucidal Effects of Black Walnut

One study from 2012 screened plant quinones for inhibiting effects on the bacterial fire blight pathogen. The most active compound discovered in walnuts was juglone. As the study said, "juglone has a potent and specific bactericidal effect on E. amylovora…Juglone is a promising candidate for the development of a new environmentally friendly plant protectant to replace the antibiotic streptomycin currently used in fire blight control."

Another study published in Phytotherapy Research found that juglone showed significant inhibition of RNase H activity in the HIV virus. This is a big deal. HIV-1 replicates itself through reverse transcription, a process that produces new double-stranded DNA from the viral genome's single-stranded RNA. During DNA synthesis, a DNA/RNA hybrid is formed as a replication intermediate and must be cleaved by RNase H before the process can continue. Inhibiting this inhibits replication of the HIV virus, and the study showed that juglone from black walnuts did just that. 

Anti-parasitic and Anti-fungal Effects

In addition to the study cited above in support of black walnut’s benefits in helping to expel intestinal parasites, the following studies are strongly suggestive. For example, a 2008 study identified types of wood that were resistant to the Emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae), an invasive pest that eats the inner bark of trees. The study found that ash borers that normally fed and developed on ash logs had no larvae and were not able to survive, grow, or develop on any black walnut trees or logs.

In truth, this is one case where experience trumps lack of studies. Any good herbalist who has used black walnut hull tincture, either internally or externally, can tell you how effective it is. Dr. John Christopher tells a great story about how when serving in the army, he used it to cure jungle rot in just four days.

It is also important to understand that many parasites do not confine themselves to our intestinal tracts. There are at least 1000 species of parasitic organisms that can live in humans, including Giardia, flatworms, hookworms, ringworms, nematodes, and a whole host of funguses. Incidentally, medical labs only check for about 50-60 of them. Some encamp in the liver, and others, such as Cryptococcus gatti, invade the lungs, nervous system, soft tissue, lymph nodes, and joints. Anti-parasitic and anti-fungal herbs such as black walnut (not to mention heavy doses of garlic) can help drive all of them out of the body. This is while you’ll find black walnut hull as an ingredient in Jon Barron’s Liver Tincture formula.

Other Uses

Before vitamins and minerals were commonly used, herbalists were known to use black walnut for a variety of conditions including easing scrofula, ulcers, wounds, rickets, scurvy and as a gargle. In more recent times, Russian military hospitals also used the nut as a cleansing and quick healing medication for wounds and ulcers.

It may also help with lowering blood pressure and cholesterol levels. The black walnut hull’s tannin content is thought to help shrink the sweat glands and reduce excessive sweating. It may also help with menorrhagia and diarrhea. Other uses include:

  • aiding digestion
  • helping relieve colic
  • helping relieve heartburn
  • helping relieve flatulence
  • stimulating bile flow
  • easing pain in spleen
  • balancing blood sugar levels
  • warding off heart disease
  • combatting malaria
  • helping with syphilis
  • helping with skin conditions such as boils and acne

 

Side Effects

Side effects associated with black walnut supplements are uncommon, and it is generally safe to use unless you are pregnant or allergic to nuts. Use while pregnant could theoretically cause birth defects or negatively impact the growth of the fetus, or potentially cause a miscarriage. The odds of any of these things happening is extremely low, but it is recommended that you not use it while pregnant.

    Do you think I can dry the hull of black walnut and use
    Is it going to be effective and how much I can have in one day.
    Also we have many different kinds of black walnut, so can I use any of them.
    Thanks

    It depends on so many factors that it is difficult to answer this question. How they are grown, when you harvest, how you dry them, etc., all effects the strength and effectiveness--something that Jon Barron took years to master with his formulas.  Hope that helps.

    Wormwood, which is also used for parasite control, can indeed impact estrogen levels in the body, but there is no evidence that the tannins in black walnut hulls have any such impact. Check with your doctor, but there should be no conflict between black walnut hulls and your Nuva Ring.

    I was not aware of the herbal importance of black walnut. I have seen normal walnuts using with chocolates and herbal creams. I was not aware that it is not good to eat them during pregnancy. Thanks for passing the mt-bc info about the health side importance of black walnuts.

    It is the hulls that are used, not the nut. The green and black hulls have slightly different applications.

    I want to say that appreciate the research on black walnut.
    As is well known stem research it is juglone. Other components of black walnut known and well studied. Synthesized juglone resistant substance and retains its chemical structure more than 10 years. However, tinctures, which are traditionally used dietary supplements do not have the stamina and if tincture preobrela brown color, juglone there disintegrated into other components. Juglone is present only in the green tincture. You can check for yourself juglone in the tincture. Add the liqueur in ammonia water. If there is juglone is cherry liqueur or pink. If tincture dark then dissolve it in water, what would it became light. The test detects the presence of juglone in a dilution of 1: 200,000.

    I do not have access to chemical research and get juglone synthetically or scientific method to remove it from the black walnut. But I have the opportunity to explore the black walnut by alchemy. As a result of alchemical study able to obtain proof of the substance juglone. This water and alcohol solution. These substances are kept open under normal conditions. Within one month changes juglone was not. The test was performed with ammonia water.

    Hello, I recently found some black walnuts at the park, and picked some of them. They no longer green skin but all black mushed under the dried leaves. I cleaned them with brush and thought the black colored water could have some benefits. First I was going to do the enema with it after boil and kill the pathogen, and look into internet and found that worm eradicating effect of it. So I boiled the black walnut in water, and let it cool and drank 3 cups after mix a little bit of water. It happened yesterday, and today I am fine nothing wrong happened. But today afternoon I became very much drowsy and had 2 hours sleep. I am very skinny person who thought the reason why being skinny could be parasite in the body. My question is that Is it okay to drink the black broth? I am not really sure if the black walnut I found was a rotten skin or the color is the way it is naturally. I tried to look for any information on website but no one mentioned the way I did. So please let me know what you think about this. Thanks.

    Hi Christy,

    There are so many variables, there is no way to tell what you took and what could be happening.  Herbalists study natural remedies for years to know what to take, how to take it, when, and why. If you are afraid of having parasites, why not just look at a full body detox and use herbal remedies that you can trust?  See our section on "How To Detox" for more information.

    There is no way for us to know how much was contained in the 3 cups you drank. It was likely much more than herbalists often prescribe. This is a pretty strong herb and it would be worth consulting with a trained herbalist.

    Within a month, drank water containing juglone, prepared from black walnut on its own technology.
    I am 62 years. The experimental results are as follows: lost, gone the extra fat but physical strength is increased. In the morning after sleep significantly decreased numbness of hands, as noted earlier. Stomach in the intestines become soft and painless. Increased mobility of the spine and limbs and long walks almost no fatigue. During exercise decreased sweating in the head region. No swelling in the legs, which had been before.

    Thank you for the article, could you clarify what you mean by "heavy doses of garlic"? How many with each meal, when (before, during, after meal), is it safe to insert it rectally and what oil can be used as lubricant (is olive oil ok?)?
    For how long shall I use it for pinworms? Do you recommend several cycles with a break between them?
    Thank you very much!

    Will taking black walnut tincture harm your liver and kidneys?

    There is no known harmful effect to either the liver or kidneys when used properly.  Actually, black walnut hull is a specific for cleansing and healing the liver. http://jonbarron.org/detox/liver-flush-tinctureKeep in mind, though, that black walnut is a medicinal herb. It should only be used on an as needed basis, or as part of a defined cleansing regimen,  not as part of a daily maintenance program.

    Will BW kill off good flora in the intestines?

  •  
    Submitted by BaselineFoundation on
    March 9, 2015 - 12:23pm

    Yes, absolutely—if you take enough of it and for long enough. Short term use is not a problem. If you have a healthy intestinal tract, the minimal reduction in probiotic colonies from short term use will completely recover in a couple of days. In exchange for getting rid of internal parasites, that’s an easy call. Longer term use will cause more damage. That’s why Jon recommends its use only for detoxes and special situations. It’s not a supplement you want to use for daily maintenance. And remember, we’re talking about the hull of the black walnut, not the walnut meat.

    I've read that kids can easily pick up parasites from school. I was wondering if it is safe to give children black walnuts every other week or once a month just as a type of maintenance. I like to put crushed walnuts on their cereal for the omga3s. Could I add black walnut powder every so often?

    someone mentioned black walnut hulls to help combat incipient pressure sores my son is prone to. for 3 years+ a T6 complete paraplegic....(steer clear of motorcycles, folks) He has not yet had a full blown sore but has highly susceptible spots on his back, butt, tailbone (he is very thin below his line of injury) ...do you have any knowledge in treating with BW Hull?...have also stumbled upon plantain leaves while looking this up and they sound like they could be useful, too. Used internally? Externally? Any advice appreciated and if effective would hugely impact a whole community. Thanks for any insight.
