According to studies done at Scientific Labs: “Black Walnut Hulls' may help to 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."
You may also use Long-term (one year)- by taking 2 capsules of black walnut twice a week to rid your body of any parasites that you may get from your family, pets or friends. Family members and friends could be harboring parasites in their gut without showing symptoms.
According to draxe.com Black Walnut Hulls:
1. Expels Parasites
One of the key active components of the black walnut hull is juglone. Juglone exerts its effect by inhibiting certain enzymes needed for metabolic function. It’s highly toxic to many insect herbivores and researchers have observed that black walnut can expel parasitic worms from the body.
According to the Pharmaceutical Society of Australia, black walnut is effective against ringworm, tapeworm, pin or thread worm, and other parasites of the intestine. This is why black walnut makes a great addition to any parasite cleanse.
2. Promotes Healthy Skin
The tannins in black walnut hulls have an astringent effect, which is used to tighten the skin, mucous membranes and relieve irritation.
3. Improves Cardiovascular Health
Black walnuts are an excellent source of alpha-linolenic acid (ALA), with 100 grams of the walnuts containing 3.3 grams of ALA.
Recent epidemiological studies suggest that frequent consumption of walnuts may have protective effects against coronary heart disease because of the promising effects on blood lipid profiles. In clinical studies, diets supplemented with walnuts decreased serum concentration of low-density lipoprotein and cholesterol.
Other potential protective constituents include high amounts of magnesium, vitamin E, protein, dietary fiber, potassium and alpha-linolenic acid.
4. Holds Antifungal and Antimicrobial Activity
It’s been suggested that the biological activity of the black walnut hull is due to the naphthoquinone, juglone (5-hydroxy-1,4 naphthoquinone). The antifungal activity of juglone has also been compared to other known antifungal agents, such as griseofulvin, clotrimazole, tolnaftate, triacetin, zinc undecylenate, selenium sulfide, liriodenine and liriodenine methionine.
In a study, it was determined that juglone exhibited moderate antifungal activity similar to zinc undecylenate and selenium sulfide, which are commercially available antifungal agents. Internally, black walnut is also used for chronic constipation, intestinal toxemia, portal congestion, hemorrhoids and giardia.
The derivatives of 1,4-naphthoquinons have been of great clinical interest since these compounds exhibit strong activity as antibacterial and antifungal agents. A series of 50 naphthoquinone derivatives was synthesized and evaluated for antibacterial and antifungal properties, with highest activity against S. aureus and candida symptoms and moderate activity against gram-positive and acid-fast bacteria.
Another study showed that juglone potentially can inhibit three key enzymes from Helicobacter pylori, a gram-negative bacterium that causes several human gastrointestinal diseases. Several algae species, including Anabaena variabilis and Anabaena flos-aquae, were inhibited significantly by juglone as well.
5. Helps Protect Against Cancer
Quinones have been associated with anticancer activity. Juglone is a quinone found in the leaves, roots and bark of black walnut trees. The exocarp of immature green fruit, bark and branches has been used in China to treat liver, lung and gastric cancer. Juglone blocks potassium channels, promotes the generation of hydrogen peroxide and inhibits transcription in cancer cells.
In a recent study, it was shown to promote cell death in human colorectal cells, and given black walnuts juglone content, it could make the black walnut a potential cancer-fighting food.
