Black Walnut was shown to combat bacterial vaginosis better than several anti-fungal supplements. Black Walnut is now found in many OTC BV cures, but is also available in concentrated form.

The bark, husk and leaves of the Black Walnut tree have been used as medicine for centuries in North America – the bark for toothache, the inner bark as a laxative, the juice for ringworm and the leaves for bedbugs and mites. You can find Black Walnut in supplement form or tablet form along with Caprylic Acid and Oregano Leaf Extract.


Black walnuts are touted as a health-boosting food for their ability to support skin, banish warts, treat cold sores, improve digestion and fight cancer.

Black Walnut contains natural tannins that kill parasites, bacterial vaginosis infections and fungus. Similarly, it is well known in the horticultural world as a danger to other plants. It also contains a chemical named Juglone, which has some antibiotic and antifungal effects. Other benefits of Black Walnut are in attacking worms and yeast infections. It may also help with lowering blood pressure, thyroid problems, diarrhea, sore throats and asthma.


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.


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.
