Black Walnut Hulls Medicinal Properties

Black Walnut, which goes by the botanical name Juglans nigra is not something many of us will be planting in our gardens, but if you have a tree on your property like we do, you have probably come across the nut or hulls on your property.  This hardwood tree grows in the US, Canada, Europe and even in parts of Asia.

Medicinal properties are said to be in the roots, leaves and hulls.

Greeks and Romans used Black Walnut for skin conditions such as fungal infections, and Chinese use it for pain in the lower to mid-back, constipation, asthma and other uses that show this plant has a number of medicinal qualities. It promotes healing of sores in the mouth and throat. It is also a parasitic.
