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

This somewhat sinister-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.

Here’s a natural herbal dewormer kit that includes both black walnut and wormwood.  The kit is a two-part program for elimination and maintenance. What’s nice about it is that it takes the guess work out of giving too much or too little.

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.

      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.

      Janie
