Introduction
Many people are familiar with black walnuts because of their rich flavor and hard shells. However, far fewer know about the thick green outer covering known as the hull.
For generations, black walnut hulls have been used in traditional herbal practices, natural dyes, woodworking, and homestead remedies. Today, they continue to attract attention from gardeners, foragers, and herbal enthusiasts who appreciate their unique properties.
While social media often portrays black walnut hulls as miracle cures, the truth is more nuanced. They contain interesting natural compounds, but many health claims remain unproven or require further research.
What Are Black Walnut Hulls?
The black walnut tree, known as Black Walnut, produces nuts surrounded by a thick green outer husk called the hull.
As the fruit matures:
- The green hull darkens.
- It becomes brown or black.
- The nut inside hardens.
- The hull eventually breaks down naturally.
