What is English Walnut?

English walnut is a tree. The fruit (nut) is a popular food. The nut, the nut's shell (hull), and the leaf are used to make medicine.

The nut is used as a part of the diet for lowering cholesterol. The hull of English walnut is used as a "blood purifying agent" and to treat digestive tract swelling (inflammation) and "blood poisoning."

The leaf is used for treating diarrhea, digestive tract inflammation, and intestinal worms. It is also used as a "blood-purifying" agent.

Some people apply English walnut hull directly to the skin for skin diseases, skin infections, and eyelid swelling. It is also used in hair dye and in sunless tanning products.

The leaf is applied to the skin for surface swelling of the skin; excessive sweating of the hands and/or feet; and for skin conditions such as acne, eczema, ulcers, and infections.

In combination with other herbs, English walnut hull is used to treat diabetes, stomach inflammation (gastritis), and "tired blood" (anemia).

In foods, English walnut is commonly eaten as a snack, in baking, and in salads.

Possibly Effective for...

  • Coronary heart disease (CHD). Some research suggests that people who eat more walnuts and other nuts might have a lower risk of coronary heart disease and death due to heart problems.
  • High cholesterol (hypercholesterolemia). 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. When English walnuts are added to a low-fat diet, total cholesterol may be decreased by 4% to 12% and low-density lipoprotein (LDL) may be decreased by 8% to 16%. 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 to Rate Effectiveness for...

  • Diarrhea.
  • Diabetes.
  • Anemia.
  • Acne.
  • Eczema.
  • Ulcers.
  • Swelling (inflammation) of the skin.
  • Excessive sweating (perspiration) of the hands and feet.
  • Other conditions.
More evidence is needed to rate the effectiveness of English walnut for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
