Black walnut (Juglans nigra) hulls have a long history as a natural dye and have also appeared in traditional and ceremonial bath practices. Because walnut hulls contain strong natural pigments, they can stain skin, fabric, tubs and other porous surfaces. This guide describes a simple traditional preparation for informational purposes rather than as a medical treatment.
What is a black walnut bath?
A black walnut bath generally refers to water infused with the outer hull of black walnuts. The hull releases a deep brown color into water. Uses vary by tradition, so there is no single standardized recipe.
How to make a simple black walnut bath infusion
- Wear gloves and protect counters, clothing and other surfaces from staining.
- Place one dried black walnut in its natural hull in a non-reactive pot reserved for craft or dye use.
- Cover it generously with water and bring the water to a gentle simmer.
- Simmer for about 15 to 30 minutes, then remove from heat and allow the liquid to cool.
- Strain the liquid carefully. Dilute the infusion substantially with bath water rather than using the concentrated liquid directly.
Important staining and handling precautions
Black walnut hulls are powerful natural colorants. Test the diluted infusion on an inconspicuous area of the tub first, and avoid light-colored towels, grout and porous surfaces. Wear gloves when handling wet hulls.
Skin and allergy precautions
Black walnut can cause irritation or allergic reactions in some people. Do not use the infusion on broken or irritated skin, avoid the eyes and mouth, and discontinue use if irritation occurs. People with known tree-nut or walnut allergies should avoid skin exposure. This traditional-use information is not intended to diagnose, treat or prevent any condition.
