- The tannins in Black Walnut Hull (and leaves) possess an astringent quality that is thought to shrink the sweat glands and reduce excessive sweating. The herb is said to help control menorrhagia, the excessive loss of blood during periods. It is also used to control diarrhea.
- Black Walnut Hull is considered a tonic that aids digestion and the intestinal system. It helps to relieve colic, heartburn and flatulence. As a cholagogue, it stimulates the flow of bile into the intestines and is thought to ease bilious colic and pain in the spleen.”
- Perhaps Black Walnut’s most well-known property is its ability to fight intestinal parasites. It is a well documented vermifuge that is effective at helping the body rid itself of parasites. As a laxative, it expels parasites as part of its cleansing of the body and the high tannin and juglone content is thought to oxygenate the blood and kill parasites. Black walnut is effective against pinworm, ringworm, tapeworm, and other intestinal parasites.
