How to Make Black Walnut Extract


Black walnut extract is commonly used to treat fungal infections and parasites; and according to the American Cancer Society, early research findings suggest that there may be a compound with anti-tumor capabilities in black walnut hulls. The hull of the black walnut is what is used to make the extract. You can make your own black walnut extract at home; however, for maximum potency, you will need to allow it to age for six to eight weeks.

Step 1

Collect freshly fallen black walnuts in the fall. Look for black walnuts with unbroken hulls and a fresh, green color with few or no dark areas.

Step 2

Wash the black walnuts well using clean, fresh water. Use a soft brush if necessary to remove surface dirt and debris.

Step 3

Place the walnuts in a large, non-reactive pot or bowl. Fill with vodka to the top of the bowl. Add 1 tsp. of vitamin C powder to help preserve the color of the black walnut tincture if desired. Cover with a lid or plate. Allow to sit at room temperature for three days.

Step 4

Strain out the walnuts and add an additional teaspoon of vitamin C powder to the liquid. Stir. Funnel the liquid into small bottles with screw tops. Tighten the bottles' tops. Store in a dark place. You can use the extract immediately, or wait six to eight weeks for better results.

Tips and Warnings

  • Black walnut tincture will stain skin, clothing and surfaces. Handle with care. Use black walnut tincture under the supervision of a trained herbalist, and as with any dietary supplement, check with your heath care provider before use.
