Non-food applications.
Medicinal.
Black walnut has been promoted as a potential cancer cure, on the basis it kills a "parasite" responsible for the disease. However,
according to the American Cancer Society, "available scientific evidence does not support claims that hulls from black walnuts remove
parasites from the intestinal tract or that they are effective in treating cancer or any other disease". Walnuts have been listed as one of
the 38 substances used to prepare Bach flower remedies, a kind of alternative medicine promoted for its effect on health. However
according to Cancer Research UK, "there is no scientific evidence to prove that flower remedies can control, cure or prevent any type of
disease, including cancer".
Medical benefits and claims.
Raw walnuts contain (mostly insoluble) antioxidants. They also contain triglycerides of the n-3 fatty acid alpha-linolenic acid (ALA) which
is effective in reducing heart risk.Roasting reduces antioxidant quality.
Inks and dyes.
The husks of the black walnut Juglans nigra are used to make an ink for writing and drawing. Walnut ink has good archival properties,
and was used by several great artists including Leonardo da Vinci and Rembrandt. Walnut husks are used as a brown dye for fabric.
Walnut dyes were used in classical Rome and in medieval Europe for dyeing hair.
Cleaning.
The United States Army used ground walnut shells for the cleaning of aviation parts because it was inexpensive and non-abrasive.
However, an investigation of a fatal Boeing CH-47 Chinook helicopter crash (September 11, 1982, in Mannheim, Germany) revealed that
walnut grit clogged an oil port, leading to the accident and the discontinuation of walnut shells as a cleaning agent.
