The Many Benefits of Black Walnut


English Name: Black walnut


Latin Name: Juglans nigra


What is Black Walnut Hull?

The black walnut is a deciduous tree native to North America that was introduced to Europe in the 17th century. Despite its popularity on both continents as a food, valuable wood source, and herbal medicine, it did not spread beyond them. Nor has it been cultivated much, largely because its roots excrete chemicals into the soil that are toxic to many other species of plant, giving the tree a competitive edge. It can grow to over 100 feet tall and produces long, slender, dark green leaves with slightly serrated edges. The dark brown, corrugated fruit — aka walnuts — are produced inside thick, fleshy, round husks that are extremely hard and difficult to crack1.


How does Black Walnut work?

Black walnuts contain very high levels of unsaturated fatty acids, like oleic acid and omega-3 and omega-6 a-linoleic acids, which have shown promise in promoting heart health. The high levels of plant sterols – or phytosterols — in black walnuts can help the body resist absorbing cholesterol and support lower plasma cholesterol, which helps keep blood pressure low. The tannins that are especially concentrated in the hulls of black walnuts have powerful antioxidant and anti-inflammatory properties, and are highly bioavailable, or easily absorbed. Walnuts are also rich in a wide array of complex B vitamins that help detoxify the body and may have neuro-protective properties2.


What are the benefits of Black Walnut?

There have been many studies linking the consumption of nuts to a lowered risk of heart disease and heart attack. In fact, the rich content of antioxidants and omega-3 fatty acids of walnuts in particular has shown protective effects on the entire cardiovascular system, including reduced blood pressure and better vein health2. Furthermore, the tannins in black walnut hulls exert an anti-inflammatory capacity on glands and other tissues of the body, making them an effective aid for digestive ailments from upset stomach to both constipation and diarrhea1. They can be especially gentle and effective for helping pets expel worms or other parasites, though black walnuts may not address the root cause of parasitic growth3.
