Specifically, when applied regularly, omega-3 fatty acids in walnut oil relieve eczema symptoms, while amino acids and vitamin E support faster skin recovery [3].

Black walnut shell oil is excellent for hair due to its potassium and copper content. Potassium helps regenerate cells and reduce hair loss, while copper produces melanin, making hair shiny and strong. When applied to the scalp, it can stimulate hair growth, helping the hair become thicker and healthier [3].

However, research on these effects is still limited, so if you wish to use it for hair care, it’s advisable to consult a specialist before applying it to your hair.

Black walnut shell powder or extract mixed with water or tea can support digestion.

Studies show that the highest concentration of juglone is found in the green hull, with an average of 31,308 mg/100g, ranging from 20.56 to 42.78 mg/100g, depending on the variety. The leaves' concentration is lower, ranging from 5.42 to 22.82 mg/100g [5].
