The nut is used as a part of the diet to lower cholesterol in people with high cholesterol. The nut, shell, and leaf are used for many other conditions, including diabetes, stomach problems, and skin conditions. But there is no good scientific research to support the use of English walnut for any of these other condiitons.
In foods, English walnut is commonly eaten as a snack, in baking, and in salads.
How does it work ?
Uses & Effectiveness
Possibly Effective for
- High cholesterol. Eating walnuts as part of a low-fat diet seems to lower cholesterol. Total cholesterol and "bad cholesterol" (LDL) are decreased when walnuts are eaten instead of fatty foods and account for up to 20% of the calories in the diet. Substituting walnuts for other dietary fats also seems to improve the ratio between "good cholesterol" (HDL cholesterol) and total cholesterol in people with type 2 diabetes.
Insufficient Evidence for
- Heart disease. Eating 1.5 ounces of walnuts per day as part of a low-fat, low-cholesterol diet may help prevent heart disease. But research is limited.
- Diabetes. Some research suggests that taking English walnut leaf extract helps to lower blood sugar levels in people with diabetes, but other research does not agree. More research is needed.
- Atopic dermatitis (eczema).
- Infection of the intestines by parasites.
- Swelling (inflammation) of the stomach (gastritis).
- Other conditions.
When applied to the skin: English walnut bark is POSSIBLY UNSAFE. It contains a chemical called juglone that can irritate the skin.
Special Precautions and Warnings
When applied to the skin: English walnut bark is POSSIBLY UNSAFE. It contains a chemical called juglone that can irritate the skin. Pregnancy and breast-feeding: The fruit (nut), leaf, and shell of English walnut are LIKELY SAFE in food amounts. But there isn't enough information to know if these parts are safe in the larger amounts used as medicine. Stay on the safe side and stick to food amounts. English walnut bark is POSSIBLY UNSAFE. Don't take English walnut bark by mouth or apply it to the skin if you are pregnant or breastfeeding.
Allergies to peanuts and tree nuts: People with peanut allergies are more likely to be allergic to nuts called "tree nuts." English walnut is a tree nut. People who are allergic to one tree nut are also more likely to have an allergy to at least one other tree nut. Doctors often advise people with peanut allergies and tree nut allergies to avoid eating any tree nuts unless you know that you are not allergic to them.
