Black Walnut for Dogs and Other Herbal Treatments for Heartworms
Among the alternatives for safe heartworm treatment, herbal therapy is
available. When the test results come out positive, and your dog does not yet
have any symptoms of heartworm disease, herbal treatment is an option you
might consider. It may not be as good as slow-kill treatment, but it is a lot
safer and less painful than the Immiticide injections. The potential benefit
of this treatment, as with the slow-kill ivermectin therapy, is that the
heartworms do not die all at once. They will never create a potentially fatal
blockage in your dog’s vascular system.
This therapy appears to be quicker than the ivermectin method but has only
anecdotal evidence to support its use. All of the comments on other websites
give glowing reviews of this therapy, but when reading those sites that are
selling the therapy, it is impossible to find out if negative comments have
been deleted.
The main component of the treatment is black walnut. Black walnut hulls have
been used for many years to treat intestinal worms. Juglone, the chemical
component of black walnuts that prevents other plants from invading its
territory, is probably responsible for its effect against worms.
What Is Involved in Herbal Therapy?
- Black walnut
- Wormwood
- Cloves
- Mugwort (Artemesia)
- Garlic
- Coenzyme Q10

How Do I Use Alternative Herbal Therapy?
****Doses vary considerably, but I will try to give the safest levels from
the various sources that I have read.
- Black Walnut Hull : One drop on the food once daily for every ten pounds of body weight. One source suggested giving only one drop the first week, another drop the next week, etc. I read of one dose considerably higher (a full dropper full for an 85-pound dog), and the owner did not report side effects.
- Wormwood : Most of the brands on sale are between 300–500mg. The number of drops or the number of capsules is imprecise; one capsule twice daily seems to be a common suggestion.
- Cloves : One capsule once daily. The strength varies considerably, depending on the brand.
- Mugwort : Two to three artemesia capsules twice daily. (Some capsules are sold with a 500mg label, some do not list the amount of herb contained within.)
- Garlic : One clove per ten pounds once daily. If the active component of garlic is to be given, the herb should be fresh, not encapsulated.
- Coenzyme Q10 : This enzyme is present in the body at all times and is sold so that it can improve the function of the heart. It is dosed around 100mg per day, but the capsules can be opened and divided for smaller dogs. (Some holistic vets recommend this for heartworm prevention. There is no proof of its efficacy.)

Are There Side Effects?
Coughing: The coughing may be due to the fluid in the lungs, a direct
result of the heartworm infestation, or it might be a side effect of one of
the herbal therapies. If you want to try an herbal therapy, yucca may be
helpful.
Find a Holistic Veterinarian
You should find a veterinarian that works with holistic medicine for
consultation if you decide to try this therapy. This therapy is controversial,
and I cannot guarantee you will find a veterinarian to support you.
The saddest part about reading all of these stories on the internet is knowing
how easy it would have been to prevent this disease. Many of the visitors who
post at the herbal sites complain about the costs, and their dogs suffer when
they could have been protected for only a few dollars per year. Treatment of
any sort is an expensive process, but much worse is the pain the dogs go
through for an easily preventable illness.
One of the products sold over several of the sites warns that their product
should be used as a preventative and ivermectin should not be given at the
same time. This is an irresponsible statement. If someone wants to try the
herbal therapy, that is fine but to tell the client to stop using the
ivermectin is wrong.

Is this effective? Many vets have tried it, and the results that have been
reported are good. No scientific studies of its effectiveness are available,
however.

The Top 10 Fastest Dog Breeds
I do not want to be too negative but can tell you for sure that some other
methods, like slow kill, definitely work. I am sure that there are plenty of
“steroid” vets who think alternative therapies for allergies are incorrect, so
at this point, I am keeping an open mind and hope that others will tell us
about their successes and failures.
Using the herbal heartworm therapy instead of the slow-kill method
(ivermectin) may not be wrong. If you do not have a problem with giving your
dog a small amount of an anti-parasite drug each month, the ivermectin will
definitely work and your dog can eventually be free of this parasite. It is
definitely less painful and does not cause as much stress as the Immiticide
injections.
If there is any research published in this area that might help your dogs, I
will add it to this article.
This video discusses juglone, the chemical produced by the black walnut tree.
This article is accurate and true to the best of the author’s knowledge. It
is not meant to substitute for diagnosis, prognosis, treatment, prescription,
or formal and individualized advice from a veterinary medical professional.
Animals exhibiting signs and symptoms of distress should be seen by a
veterinarian immediately.
Questions & Answers
Question: How long should I use black walnut to treat an 80# dog for
heartworm, using the 1 drop per every 10 pounds? That would be 8 drops per day
for how long?
Answer: The information available is only anecdotal. No clinical trials
have proven that this works, but some veterinarians reccommend 2 to 3 weeks of
treatment.
Please do not treat longer than that. There have been cases of toxicity
reported. None of these cases have been proven, however.
Question: Do you have a specific chart of proper dosage for Black Walnut
hull extract for my dog?
Answer: No, the dose has not been worked out that well anyway. Sources
vary but some recommend one drop per 10 pounds of body weight.
Question: I have 3 dogs at about 100lbs each. None have heartworms but I
live in the south. I would like to try an alternative but don’t quite
understand dosage. What do you suggest?
Answer: This alternative has never been investigated as a preventative,
only as a cure. I cannot recommend it as a preventative. If you want to
prevent this painful disease in your dogs, which you definitely should, look
into giving oral heartworm preventative. You can purchase sheep dewormer very
cheap, and a bottle will last you for years. Here are the dosages:

Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 27,

Danielle, there are no exact dosages, but some practitioners recommend a drop
per 10 pounds, so for your dog give two drops a day for no longer than 3
weeks. It has been reported to be toxic if given too long. There is no
evidence how fast this becomes effective or how long to wait before the
testing becomes negative.
Danielle Shae on August 27, 2020:
Hi Mark,
I know you published this article sometime ago, but I have a few questions. My
dog milo tested positive for heartworms in June. He’s 5yrs old and weighs 14 –
18lbs. He is not showing any symptoms.
But what I wanna know is, How should I administer the black walnut treatment?
should I give him one drop a week or once a day? and for how long, 6 months
maybe or less? I have no idea how quickly this is suppose to take effect to
kill off the worms. I want them all to die before I get him tested again.
Suzanne OBRIEN on August 27, 2020:
Hi. Most likely asking that Ivermectin NOT be used in conjunction with the
herbal is due to complications/interactions between them. Also, if you’re
using both then you truly don’t know what worked. For the last decade I have
been using pawhealer.com Heartworm Support TCM herbal. Our Doberman tested
negative annually for 9 years and we live in Dallas where you absolutely must
treat regularly and all year too! NOT antidotal
Dr Mark (author) from The Atlantic Rain Forest, Brazil on June 21, 2020:
Bernadine, there are no contrainidications as far as I am able to research
this.
Bernadine on June 19, 2020:
Can I give the herbal remedy for heartworms while my dog is on the Advantage
Multi?
Jennifer D from Memphis on August 09, 2019:
Dr. Mark, I ordered the sheep French. I wish I could have caught him sooner.
He ran feral for 6 years. Thank you very much.
Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 09,
2019:
Jennifer I do not think the black walnut is going to help at this stage. If
your dog is already coughing he has most likely developed some heart
enlargement due to the heartworm infection.
Since you are already giving heartgard, take a look at the information on slow
kill with ivermectin. https://pethelpful.com/dogs/Safe-Heartworm-Treatme…
It is going to be a lot less expensive than the other options, and you can get
a sheep drench product (the same thing that is in Heartgard) for a lot less
money.
I wish I could give you a more positive answer. You can read about the stages
here: https://pethelpful.com/dogs/heartworm-symptoms-in-… When he gets too
bad you may need to make a hard decision.
Jennifer D from Memphis on August 07, 2019:
My dog was feral for 6 years and I have had him 6 months. He is a 58 pound,
6-8 year old lab mix. He has heartworms and I do not have the $2000. for the
treatment. I give him the heartguard once a month. The past few days, he has
started coughing pretty severely. Will black walnut help him?
Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 04,
2019:
I think your vet recommended that you not use the traditional rapid kill,
which is a chemical that causes all of the heartworms to die at once. It is
harsh. The slow kill method is not.
No, I cannot tell you that these methods are going to be any easier on her
than the slow kill method with ivermectin.
Whether you decide to try one of the treatments above, or the slow kill
method, you should do something. Death secondary to heartworms is terrible and
should be avoided if at all possible.
Best of luck with her.
Cean 13 on August 01, 2019:
Thank you for this information. I have a 14 year old girl who has just been
diagnosed with heartworms. Her only symptoms so far are sleeping for much of
the day (could just be age) and occasional coughing, though not daily. Due to
her age and health our vet doesn’t recommend the traditional slow kill
treatment as it can be very harsh. Would any of the mentioned holistic
rememdies be a safer and gentler method of treatment? Her quality of life is
still very good, she is playful and eating well and though we know that most
likely we will have to make an end of life plan in the foreseeable future, I
would spare her from any discomfort due to heartworms if they can at all be
treated. Thank you.
Dr Mark (author) from The Atlantic Rain Forest, Brazil on July 15, 2019:
Marissa, there is no experimental data for that. If I was going to use black
walnut (I prefer the slow kill method with ivermectin) then I would start
right away.
Since you do not mind using the Interceptor, I suggest you look into the slow
kill method.
Marissa on July 14, 2019:
Hello, I could pay for full heartworm treatment, so I took the Interceptor
plus because I needed a specific preventative since my dog already has
heartworms. I also gave her 1 pill of bravecto. In your opinion would my dog
taking these medicines and trying the black walnut possibly be a bad mix. Or
would it be a good idea to try a drop a day for the first week and monitor
her?
Dr Mark (author) from The Atlantic Rain Forest, Brazil on July 14, 2019:
Sabrina, there is no evidence that all of the products would work better than
just the one. I think you should try the black walnut or wormwood first,
monitor the results, then go on to the next alternative.
Sabrina on July 12, 2019:
do. i use all of the herbs together or just try one thanks
Dr Mark (author) from The Atlantic Rain Forest, Brazil on June 14, 2019:
Wedel, garlic is related to onions. Onions are bad for dogs. Therefore, the
wisdom of the internet claims that garlic is bad for dogs.
This is so much …. Garlic is not bad for dogs.
wedel on June 12, 2019:
Howdy
I thought garlic was bad for dogs?
Dr Mark (author) from The Atlantic Rain Forest, Brazil on June 08, 2019:
Jennifer, nosodes do not work. This has been proven in numerous experiments.
The people that are still using them refuse to accept the truth.
The article does give the black walnut dose. It is one drop per 10 pounds.
This is a treatment, not a preventative. No one has ever proven that this
works to prevent the disease.
(I use ivermectin on my own dogs, It is a very tiny dose, and only given once
per month. It is certainly a lot less chemicals than most dogs come into
contact with each day just running around the yard, eating things off the
ground, and breathing air.)
If you are interested in this preventative here is an article I wrote with
doseages https://pethelpful.com/dogs/Heartworm-Preventative…
Jennifer on June 06, 2019:
I found some information about using heartworm nosodes as a preventative and/
or treatment. It seems like not a lot of information about it is out there,
other than the few holistic vets that offer them and say it has worked for
them for years. I would be curious on your thoughts of this verse the Black
walnut with other herbs as prevention as I sure don’t see a recommended Black
walnut dosage/ guideline on how much and how often?
Dr Karl Buchanan on January 15, 2019:
The use of Black Walnut, Clove & Wormwood appears to work on dogs as well as
it does humans to me?
Personally, I would avoid ivermectin at all costs. It is harsh and doesn’t
have any benefits. I don’t worry about feeding the herbs twice a year and we
have been very happy.
We build the doses up over a week of course, 1-2-3-up to weight, but they can
eat it for 6-8 weeks. We don’t even use piperazine for dogs or cats these
days.
Some other herbs are helpful in prevention between wormings.Our dogs use
essiac and reishi/cordyceps/turkey tail mushrooms as regular diet staples.
They are much gentler as a purgative, but still seem to render the body an
uninhabitable place for heart worms owing to acidic components in them.
That has been our experience over 20 years with over 50 dogs at Rosewood
sanctuary & special needs house. It’s always good to find less harsh remedials
that may even have benefits.
Dr Mark (author) from The Atlantic Rain Forest, Brazil on September 13,
2018:
Pat, not at all. I think that is in the best interest of your dog.
Pat on September 13, 2018:
After three weeks od herbal thereapy does it hurt to give your ivermectrin
once a month?
Dr Mark (author) from The Atlantic Rain Forest, Brazil on July 17, 2018:
Bailey, I can certainly understand your reluctance to use the arsenic
injections. I am much more positive about the slow kill method since your dog
does not have clinical symptoms. The worms take longer to die, but they will,
and the effects are a lot less serious.
Read this and let me know if you have any questions:
https://pethelpful.com/dogs/Safe-Heartworm-Treatme…
BAILEY on July 16, 2018:
MY DOG HAS AN APPOINTMENT COMING UP WITH THE VET THOUGH I’VE THOUGHT ABOUT IT
SINCE I SET THE APPOINTMENT FOR HER. I CAN’T BY ANY MEANS PUT HER THROUGH
SOMETHING SO HORRIBLE AS TO LET THEM INJECT HER 2 DAYS IN A ROW WITH ARSENIC
TO BE IN SUCH HORRIBLE PAIN AND TO MAKE HER SO SICK. I’M NOT TAKING TO HER
APPOINTMENT. I’VE READ ABOUT SOME NATURAL REMEDIES (BLACKWALNUT, HAWTHORN,
WORMWOOD ARTEMESIA, COCONUT OIL, GARLIC, CARROTS, VRM2) ARE ALL SUPPOSE TO BE
GOOD FOR KILLING HEARTWORM, BUT I READ SOME BLOGS AND SOME STATED THAT
BLACKWALNUT DOESN’T KILL HEARTWORM IT STATED ITS MORE LIKE A PREVENTIVE. COULD
YOU SUGGEST ANYTHING FOR MY DOG TO TAKE, I’M RUNNING OUT OF TIME CAUSE THE
ONLY SYMPTOM SHE IS SHOWING IS THAT SHE SLEEPS ALOT AND WHEN I TAKE HER OUT
FOR HER WALK SHE PANTS ALOTS BUT SHE HAS A THICK FUR AND ITS HOT OUTSIDE. SHE
IS A VERY PASSIVE AND CALM AND BEAUITFUL DOG. I DON’T WANT HER TO SUFFER AND I
DON’T WANT TO RISK HER LIFE WITH THE INJECTIONS THE VET HAS. SO IF BY ANY
CHANCE COULD YOU GIVE ME ADVICE ON WHICH OF THESE I COULD USE TO KILL THE
HEARTWORMS. I’VE BEEN GIVING HER COCONUT OIL, CARROTS, AND GARLIC EVERY DAY
WITH HER MEALS.
Dewdog on September 06, 2017:
I believe this derived from The Honorable Late Doctor Huda Clark… Amazon has
her books…. Her clinic in Mexico was the Only clinic with a 100% success for
healing diseases. I’ve done the black walnut tinc. , Wormwood, Clove and
boiled a bundle of fresh parsley for 3 min. In 1 quart of water(1 teaspoon for
every 10 pounds and keep it in the freezer- flushes the kidneys after
parasites die).
KITKAT on June 03, 2017:
I will have to try this. My son’s dog was on Heartgaurd plus which worked good
but then the vet changed him to Trifexis and this heartworm medication almost
killed him. He hasn’t been the same since. We are going natural from now on.
Thank-You!
Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 10,
2012:
The directions on doses are in the article “Heartworm Prevention for your dog
for less than 10 dollars a year”. I bought a bottle of the cattle dewormer for
my dog and she only gets one drop a month. The sheep dewormer is less
concentrated but it is still a very small amount. Take a look; it is really
affordable.
Mel Flagg COA OSC from Rural Central Florida on August 09, 2012:
Mosquito season is pretty much March through the end of October lol
What’s this sheep drench alternative? Hubby’s on workman’s comp at the moment
till he heals from surgery, and it’s almost time for her treatment… every
little bit helps!
Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 09,
2012:
Thanks for your comment. Again, I want to emphasize that the black walnut hull
seems like an effective antiparasitical but not a heartworm preventative. I
apologize if I am harping on the issue but the conventional preventative is so
cheap and effective, and the failure to prevent the disease can be so terrible
for the dog.
Judith C Evans from Boise, ID on August 09, 2012:
Lots of valuable information here! I did not know about black walnut hull as
an anti-parasitic. Glad you published this article!
Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 09,
2012:
I agree that the black walnut hull tincture looks like a great natural remedy
for intestinal parasites, but the heartworm preventative is such a small dose,
just one drop once a month during mosquito season (which is all year down
here, not sure about Florida), that even the ivermectin sensitive dogs like
Shelties and Aussies can handle it. Most of the posters on the internet
complain about the high price too, which is true if you are supporting the big
pharmaceutical corporations. If you buy the sheep drench alternative though it
is less than 10 bucks a year. I live frugally, but I can´t see anyone who owns
a dog thinking that is too much.
Mel Flagg COA OSC from Rural Central Florida on August 09, 2012:
Fascinating read! I’ve actually been looking for an herbal remedy to treat
intestinal worms, the treatments from the vet make my cats violently ill and I
wonder if they were given an improper dose. So the black walnut may prove
beneficial.
I agree with you that for heartworms the best treatment is prevention. One
shot every year is a much better alternative to the suffering of a dog, or any
animal. Unfortunately, Sekhmet does get sick a few days after treatment, and
I’ve been looking for a safer preventative that actually works. I don’t trust
pharmaceuticals mainly because we really don’t know exactly what they do in
actual practice. We only know what they do in a lab. But sometimes they are
unavoidable.
I suspect the best route for natural prevention would be mosquito repellant
lol. But I have yet to find a decent herbal that works. At any rate, this is a
step in the right direction. It does make me wonder again about vitamin C…
😀
Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 08,
2012:
I don’t see how. The brewers yeast boosts vitamin B levels, garlic (fresh, not
capsules) has allicin, a chemical that in some way repels external parasites.
I really think ivermectin is the only safe way to go for prevention.
wetnosedogs from Alabama on August 08, 2012:
Interesting, indeed. Would the garlic in brewer’s yeast and garlic tabs work
against heartworm?
Dr Mark (author) from The Atlantic Rain Forest, Brazil on August 08,
2012:
I really appreciate the kind words. If you are interested in natural health
solutions for your dog I have published a lot of articles on the subject.
Unfortunately I do not think this is the best alternative for heartworm, but
we have to keep searching.
Reynold Jay from Saginaw, Michigan on August 08, 2012:
Thanks for the great information here. I love dogs and anything we can do for
them is my mission in life. I enjoyed this very much. You have this laid out
beautifully and it is easy to understand. Keep up the great HUBS. I gotta give
this an Up ONE AND very INFORMATIVVE . I’m now your fan!
