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.
In at least one study, Black Walnut husks were shown to combat Candida as effectively as several commercial antifungal drugs. Black Walnut is now found in many over the counter Candida cures, but is also available in concentrated form.
How Does Black Walnut Work?
In a 1990 University of Mississippi study (see here), the active ingredient in black walnut (juglone) was shown to be as effective as some commercial antifungals. According to the study, the test results “for juglone showed it to have moderate antifungal activity and to be as effective as certain commercially available antifungal agents such as zinc undecylenate and selenium sulfide.”
Black Walnut contains natural tannins that kill parasites, yeast and fungus. Similarly, it is well known in the horticultural world as a danger to other plants.
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.
How Do You Take Black Walnut?
For Candida, the best form of Black Walnut to take is the husk (or hull). The nut is harvested when green and then soaked to remove the husk. It is then soaked and the extract removed. It is as an extract that Black Walnut is most effective.
Black Walnut extract is usually sold as a tincture, or alcoholic solution. Don’t worry too much about the alcohol – it is used in such small quantities that its effect is minimal.
Who Should Not Take Black Walnut?
Those who have existing liver or kidney conditions should be careful with Black Walnut as it may irritate these organs. Pregnant or breastfeeding women should also avoid taking it, as should those with gastrointestinal conditions other than Candida.
Black Walnut Side Effects
No side effects have been reported in humans taking Black Walnut. It does however contain high levels of tannins, chemicals that have previously been associated with damage to the liver and kidneys.
