In this entry of our series on herbs for dogs, we’re going to talk about using black walnut.

This somewhat scary sounding treatment is common throughout eastern North America, but it’s also found as an ornamental tree in other parts of the United States and throughout southern Canada.

It was introduced in Europe in or around about 1629 and is still cultivated there for its wood.

Black walnut blooms in the springtime and actually bears its nuts in the early summer. Interestingly, the black walnut flowering tree is more resistant to frost and other elements than other walnut trees.

To this day, black walnuts are still harvested by hand from the wild trees. The majority of nuts harvested come from Missouri, with the largest black walnut processing plant located in that state. The outer hard black walnut shell is used in a number of applications, including in commercial cleaners and even in oil well drilling.

At this point,  you’re probably wondering exactly why anyone would be recommending black walnut for dogs. This is where things get interesting. Black walnut is notorious as much for its misuse in herbal applications as it is for its proper use.

Let’s be clear: black walnut is one of the safest and most reliable worming agents of all the herbal options we’ve explored thus far. BUT, used improperly, black walnut can be as toxic to the host as it can be to the tapeworm. Proceed with extreme caution, in other words.

Therapeutic Uses

As mentioned, black walnut is one of the best worming agents out there. The green, unripe nut hulls are used to create a series of over-the-top worming agents. There are also alcohol tinctures available that use black walnut.

  • Approaching this from a holistic mindset, black walnut worming agents offer what is called a symptomatic worming agent that is easier on the body and better than most other herbal agents on the market.  The trouble with merely approaching worming from a symptomatic point of view is that it doesn’t get at the reasons your dog has worms in the first place and therefore it won’t actually CURE the underlying issues.
  • Now, making your own black walnut tincture is something that we generally only advise for experienced herbal users. You should start with just a single drop of the stuff in your pet’s food and monitor any signs and symptoms going forward. If there are any adverse effects whatsoever, discontinue use immediately and seek medical attention from a veterinarian.
  • A tincture is generally about 40 to 60 percent alcohol, with black walnut tincture being the most effective when the green hulls are soaked in alcohol for at least three days and as many as three weeks. There are some tinctures that are not good for internal use, so be sure that you purchase one that is safe for dogs and internal use.

How to dose black walnut tincture: Use regular strength only – start slow over a couple of days by working up to one drop per 10 lbs body weight daily.  Herb Pharm Black Walnut Extract

How to dose black walnut capsules:  Dogs weighing 5-25lbs : 125mg or a 1/4 of a 500mg capsule.  For dogs weighing 25 pounds and over, give 250mg or 1/2 of a 500mg capsule daily.  Nature’s Way Black Walnut Hulls Capsules – 500mg.

Preventative Measures

As mentioned, there are many reasons to be wary around black walnut. Despite the fact that it is, when used properly, tremendously effective at doing what it does, it can also be toxic if used improperly. As we always caution, anything that can be used to kill something like a tapeworm can also have adverse effects fr your animal.

Be extremely careful with black walnut and, if you have any doubts at all about this treatment option, avoid it.

Reasons to Use

As mentioned, black walnut can be a tricky one. It is as good a symptomatic treatment for worms as there is, but using it as such avoids getting to the heart of why your dog has worms and only serves as a very effective bandage on a larger problems.

For this reason and because of the aforementioned preventative measures, we discourage use of black walnut for most cases and suggest that it only be used where absolutely necessary.

      Hi Jack:

      Are you using this for heart worm because your dog currently has heartworm, or for prevention?

          Jack, while I say in the article that it’s safe when used correctly, this statement is actually pretty broad and I should probably reword it. You have to be extremely careful with this herb and consult with a holistic veterinarian which would most likely combine it with other anti-parasitic herbs.

          I DO NOT recommend that you blindly add black walnut to your dog’s daily diet, without some sort of guidance from a holistic vet, etc.

          Jeff Battershaw claims to be a trusted natural heartworm authority figure. This might be a good place to look. Read the messages in the forum as well. Reach out to him and ask questions. Here’s a link.

          It would be so helpful to others if you could stop back here at some point down the road and let me know how it went. We’re all trying to find the best possible ways to naturally prevent and heal our old friends when possible. So, any knowledge you gain could benefit so many others.

          Whatever you do, I would definitely use a natural method of heartworm prevention for all your dogs in the future. I have one in the article that is good.

          Anyway, I hope this helps Jack.

    I think I may have given my dog a overdose. We found out she had heartworm and I was given her a half of a full dropper that came with liquid bottle from the heath food store. I been mixing it in her food. Tonight my German Shepherd vomited up her food. What should I do now?

      Hi Anthony:

      If your dog has heartworm already and is vomiting up her food; if you haven’t seen a vet yet, you should. Black Walnut contains tannins and alkaloids that are often associated with vomiting and/or diarrhea.

      Heartworm isn’t something to play around with and if you’re uncertain as to what you are doing — PLEASE TAKE HER TO A VET IMMEDIATELY! Or, talk with these people here about their natural product kit for treating Heartworm.

      I don’t recommend you do this alone Anthony.

      Interested in knowing what happened to your German Shepherd? My husband found these drops online and decided to give it to our German Shepherd as well. He got extremely sick. We had been to vets and they would always tell us he had allergies but after researching we concluded he had a yeast infection. My husband found the nzymes products online and thought it would help. Any info would be great.

      Anthony not sure if you are following this group anymore. But I’m wondering what happened with your dog. Please if you could share any info. My husband found these drops online and gave them to our German shepherd and he got extremely sick! We took him to the vet and they found he had a twisted intestine and there was nothing they could do. I miss him so much and feel horrible. Just trying to find answers if possibly the drops caused intestinal issues since our dog also got diarrhea and had vomitting that weekend and the only new thing he was exposed to was these drops. 🙁

          Thanks Janie, I feel terrible and miss him so much. We had been to the vet multiple times trying different things with them saying he had allergies. Nothing was working and my husband found a website online nzymes.com and ordered a kit from them. The weekend this happened the only new thing we had done was given him the black walnut and olive leaf drops. The instructions were to give him 12 drops. He then less than 24 hours after giving him the drops started having diarrhea and vomit. But before that he was his happy normal hyper self. I couldn’t believe how quickly it turned and how he went from active to gone so fast. I went online to try and find some kind of answer. I found that black walnut can cause gastritis and digestive issues and wonder if those lead to his intestine twisting. We were only trying to do our best to take care of him and feel terrible and at a complete loss with him gone. 🙁

          • janie

            I’m sorry Jen. Black Walnut is without a doubt a very powerful herb. Bloating is a very frightening experience and it’s something that I want every dog owner of large dogs to understand how quickly and deadly gastric torsion can be. There’s very little time think.

            Prevention is key with this condition. Not sure if you want to Jen, but if you’d like to read my article on it, you do that here.

            I feel terrible Jen and I know that you and your husband were just trying to make your him better.

            We’re always here if you need us, even if just for support.

      Hi Brenda:

      I’m glad you’re looking into a natural approach, however, I don’t know the exact recipe for the black walnut, wormwood and cloves tincture to treat giardia in your big boy.

      You’re best bet is to just use something like Kochi Free if you know for sure that you’re dealing with Giardia. It’s simple, natural and effective.

    Hi, I found this heartworm preventative program after researching online.

    The program that consists of three products:

    Artemisia Combination (389 mg/capsule) – This is used like a monthly de-wormer.

    Black Walnut (500 mg/capsule) – This is a great nutrition booster helping metabolism and keeping the animal less desirable by parasites [fleas, ticks, and mosquitoes].

    HS II (460 mg/capsule) – This is used to keep the heart strong.

    Since weight determines the amount of herbs that should be taken, here’s what Robin suggested for healthy dogs.

    Under 5 lbs – 1/4 capsule Artemisia Combination and a sprinkle of Black Walnut capsule [equivalent to an eighth of the capsule]
    5-10 lbs – 1/2 to one capsule Artemisia Combination and a 1/4 of Black Walnut capsule
    11-25 lbs – 2 capsules Artemisia Combination and 1/4 capsule Black Walnut
    26-50 lbs – 2-3 capsules Artemisia Combination and 1/2 capsule Black Walnut
    51 lbs and over – 3 capsules Artemisia Combination and 1/2 capsule Black Walnut

    Artemisia Combination is given the first week of each month. Black Walnut is given 5 days on, two days off. I’ve found that most pets like Black Walnut. A little bit of Black Walnut goes a long way, so be sure to adjust this according to weight like the rest of the program. HS II is used to keep the heart strong. It can be given every few days or at least once a week.

    *NOTE: If you have a dog that is not in good health, we advise that you check with your veterinarian before using the program. The amounts aren’t as critical as when you are working with a dog that has heartworms.

    Another thing to consider is if you are in a climate area that has a winter and a period of time where there are no mosquitos. Vets generally do not tell you to use heartworm medication at that time of the year. I don’t bother to use the spritzer at that time of the year, but I still do the herbal program because Black Walnut is such a healthy supplement and the Artemisia Combination keeps him parasite free.

    Please use wisdom and common sense in deciding whether the natural approach is for you and your pet family. Since the herbal way is less expensive than the drugs, please be sure you make the investment to have your dog tested annually.

    You can read the full article and decide for yourself if this is the course of action you feel is appropriate for your pet. The actual Heartworm Program for heartworm positive dogs is also found on this site. My pup is currently heartworm positive and we are attempting this method. It’s slow and steady and requires a lot of patience, pills, and ham. Good luck.

      I’m so sorry to hear that your dog is heart worm positive. Thank you so much for sharing the article. Much appreciated.

      Will you please stop back and give us an update on your dog’s progress? We’ll keep our fingers and paws crossed that all goes well. 🙂

        Thanks Janie…She’s doing well. Her cough is nearly gone but we won’t know for sure for a few more months when we have her retested. It seems the average time for other heartworm positive pups was 4 to 6 months before they were negative. It’s quite a regime with 5-6 pills faithfully morning and then again at night, as well, as keeping her stress free. Luckily for us, she loves ham so much she gobbles the capsules without missing a beat and naps most of the time anyway. I read that yucca can help with bad coughing, but we haven’t had the need to order any.

    Also…you don’t have to purchase the herbs from the website I used. Any trusted herbs’ source is fine as long as the dosage is the same for the given weight ratios. I also have my very large bloodhound on the herbal heartworm prevention program of one week on then three weeks off. We will have her tested in March to verify she is still negative.

    Hi, my dog has been recently diagnosed with both heart worms and Lyme though she acts fine. We are out in the country as of two years now and have been inundated with ticks here. Wish we’d never moved here. The vet is going along with my wishes to use the “slow method” which is heartgard once a month until she’s clear of heart worms and doxycycline twice a day for the additional symbiote that accompanies heart worm, can’t remember the name of it at the moment. I assume the doxy. is also for the Lyme. I have added Bandit’s Buddies heart worm system to this although she is giving me more trouble than ever before in her life getting all these pills/capsules into her. Since the dog my Son and his family left here was also coughing I am assuming he also has heart worms and have put him on the Bandit’s Buddies also. They don’t help me with expenses for him so I am hoping this will be sufficient for him. If anyone has any other suggestions please let me know. Don’t suggest tea tree or D.E. as I know tea tree is toxic for dogs and D. E. hasn’t worked in all the years I have used it other than possibly having caused my lung problem. The ticks climb right up my rubber boots right over the permethrin and the 40% deet spray I put on them and straight up my clothes so I am very discouraged over that. I have been bitten by them so many times that I won’t be surprised if I also have Lyme. Last year while hunting through the woodsy areas on this block for my lost little old gentle cat for 3 days straight with only a few hours sleep I got a tick bite that became infected. Found my cat though, someone had tried to beat him to death as well as having shot a hole clean through his tail. The vet did three surgeries trying to enable him to eat and drink again with a dual break to his jaw. He survived with great effort on both mine and the vets part and can eat now but isn’t quite the same cat. He’s still a lovey dove though. Lately I have been having burning ice like sensations on my hands as if someone is applying a cube to small varying areas on them and wondering if that is a symptom of Lyme.

      Hello:

      I’m sorry for the delay and I’m even more sorry for your dog’s diagnosis of heartworm. I highly recommend that you purchase Dr. Falconer’s ebook on healing and preventing heartworm in dogs holistically. It’s going to cost you $47, but you’ll be a member of his program/website, etc. Here’s a link for you. It’s an easy to read book and I’m sure if you have questions, he’ll answer.

      I would also purchase the book the from Stephen Buhner “Healing Lyme”. There is a protocol in there on page 76, but I recommend you actually read the book. Here’s a link to the book. This gives you the resources to heal Lyme naturally. He is the master of healing Lyme disease naturally. Keep in mind that it could take up a year and you should follow the protocol!!!!

      Above all, you must feed your dog a good diet that consists of species appropriate foods — NOT KIBBLE or COMMERCIAL CANNED FOODS! This is critical for prevention and treatment for both of these diseases and well as all others.

      I’m so sorry to hear about your cat as well. It is heartbreaking to me that people can be so cruel.

      I hope this helps. So often I ask people to come back and let me know how it goes, because it is these testimonials, whether good or bad, that help others make an informed decision. So, please let me know. Even if it’s a year from now.

      Warmest regards,
      Janie

      We were having issues with ticks until I discovered the suggestion of 100% Rose Geranium essential oil. One drop between dogs shoulder blades and one at the base of the tail before going out. On you, a drop behind each ear and on your knees.

    Sorry to hear about the awful experiences you have had with black walnut and your dogs.
    I have given this to my dogs many years ago with no complications at all.
    Through my holistic vet I dosed my boxers each month from May to October for about 5-6 days before the full moon. I can’t exactly remember the amount but it was around 7-10 drops (eye dropper) once a day.
    I haven’t used it now for quite a few years.
