How to Dry Black Walnut Hulls

Dried black walnut hulls are useful in a variety of ways, according to "The Herbal Home Remedy Book: Simple Recipes for Tinctures, Teas, Salves, Tonics, and Syrups." For instance, you can grind them to prepare a tincture or herbal blend. Walnut trees are native to North America and produce black walnuts that are potent in juglone, an anti-parasitic agent that keeps bugs from infesting the walnuts on the tree. The same agent also offers therapeutic benefits to people.

Step 1

Cut away the green exterior of the black walnuts.

Step 2

Crack open the black walnut hull with a nutcracker.

Step 3

Place the black walnut hulls in a food dehydrator. If you don't have a food dehydrator, the book "Making Plant Medicine" advises placing the hulls on a cookie sheet in a dark, dry room.

Step 4

Assess the walnut hulls daily. When they have turned a deep brown, they are fully dry. This typically takes two to three days when using a food dehydrator, and four to five days when placing the walnut hulls on a cookie sheet.
