Antifungal & Antibacterial 


Black Walnut's main constituent, Juglone, has antifungal properties useful for conditions such as athlete's foot and ringworm. One study showed that Juglone inhibits the bacteria Helicobacter pylori, responsible for causing gastritis and peptic ulceration. It has been suggested that Black Walnut and the compound Juglone could become a new antibacterial agent to treat infections and prevent antibiotic resistance. 
Black Walnut has antifungal actions that have shown to be effective in reducing Candida. A study conducted at the University of Mississippi concluded that Black Walnut Hulls prevented Candida from developing and growing by inhibiting enzymes needed for yeast metabolism.


Antiparasitic


One of the primary benefits of Black Walnut Hulls is their ability to expel gastrointestinal worms and parasites. Black Walnut Hulls, are frequently used in parasite digestive cleanses for their high content of tannins and Juglone to improve bowel motility and expel parasites.


Constipation & Diarrhoea


Herbalists commonly use Black Walnut extract to relieve constipation and diarrhoea due to the astringent and soothing effects that the compound Juglone has on intestinal tissue.
