How to Make Dry Black Walnut Powder


A natural plant source of iodine and other beneficial materials, the black walnut presents itself as a useful food. Black walnut powder is made from the shells of the black walnut because they are more potent than the nut meat. Making your own black walnut powder from your walnut trees enables you to experiment with herbal treatments for conditions such as gas, inflamed skin and many others.

Step 1

Add about a pound of black walnut shells, also called husks, to a food processor.

Step 2

Process the husks on the processor's highest setting. Do this for about 2 minutes straight.

Step 3

Pour the grated husks onto a cookie sheet.

Step 4

Bake the powdered husks at 400 degrees Fahrenheit for about 25 minutes.

Step 5

Allow the black walnut powder time to cool to room temperature, and then bottle it for future use.
