BLACK WALNUT HULL (juglans nigra)

About this Herb

Besides being one of the most effective herbal laxative remedies and also being rich in Vitamin C, black walnut hulls have a long history in herbal medicine. Pliny the Elder, the Roman naturalist, talked about their healing power in the first century A.D. Seventeenth-century herbalist Nicholas Culpeper prescribed walnut to draw poisonous venom from snake and spider bites. It was the Native Americans, however, who first used black walnut hulls as a laxative and as a treatment for eliminating parasites in the intestine.lower blood pressure and serum cholesterol levels and is believed to burn up toxins and fatty materials while balancing blood sugar levels. 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 Native Americans used the bark, hulls and the leaf of the Black Walnut tree in their traditional medicine.  It was used as a mosquito repellent, for skin disorders and the hulls were used to expel parasites from the intestines.

In Traditional Chinese Medicine they were regarded as a kidney tonic, and the bark, kernel and the hulls were also used to eliminate various types of intestinal worms and parasites.

Black Walnut Benefits


One of the key benefits of Black Walnut Hulls are their ability to expel various kinds of worms and parasites that live in the intestines. Often making an appearance in parasite cleanses, Black Walnut Hulls contain juglandin, juglone and juglandic acids as well as tannins and organic iodine.

The primary active constituent in Black Walnut is a “naphthoquinone”, known as juglone. Juglone is a natural herbicide that exerts an inhibitory effect on certain enzymes needed for metabolic function. It is thought that the high tannin content is also responsible for the anti-parasitic properties of Black Walnut, helping to eliminate microbes from the large intestine. The high tannin and juglone content is also thought to oxygenate the blood which can kill parasites and working as a laxative, it expels parasites as part of its cleansing of the body.


Intestinal Candidiasis is an overgrowth of the Candida fungus, which can actually weaken the walls of the intestines and release toxins into the bloodstream. This plays havoc with the immune system and can manifest in a whole range of baffling symptoms which can be very difficult to diagnose.

The hulls of the Black Walnut are also powerfully anti-fungal, making them a potential Candida killer that may be even more effective than their pharmaceutical counterparts. A study conducted at the University of Mississippi in the 1990’s showed it was just as effective, if not more effective, to use Black Walnut, as it was commercial antifungal preparations. The active ingredient, juglone, has been shown in studies to have an anti-fungal activity and it can also prevent Candida from growing and spreading due to its inhibitory effect on enzymes in the yeast that are needed for metabolic function.

Digestive Health

Apart from expelling nasty parasites, fungus and bacteria that can interfere with digestion, Black Walnut Hulls promote healthy digestion and gastrointestinal health. They encourage bowel regularity due to their gentle laxative effect and promote healthy bile flow.

The hull of the Black Walnut is said to tone and heal inflamed intestinal tissue, as well as improving the environment of the digestive tract for more effective assimilation and elimination. It is for this reason that Black Walnut is unusually considered a treatment for both constipation and diarrhoea.

It is also effective against Helicobacter pylori (H. pylori) – a bacteria that is responsible for the majority of ulcers that occur in the stomach.

Excessive Sweating

In one of the more unusual benefits of Black Walnut, it is known to help to reduce excessive sweating. The high levels of astringent tannins contained in the hulls are believed to have an effect on overactive sweat glands and decrease the amount of sweat they produce.
