As with most nuts, they have a gentle laxative effect on the body, lubricating the large intestine.
Black walnuts are a good source of arachidonic fatty acid, which some studies show relieve bursitis symptoms.

They are also a good source of Vitamin E, a powerful antioxident good in the fight against cancer and heart disease. Some studies have shown Vitamin E promotes mental well-being and eases arthritic pain. Many people and some animals are allergic to the pollen when the tree blooms (typically in May).
