What is black walnut hull, and how does it differ from the ordinary walnut? — Black Walnut Hulls 500 mg, 60 capsules - Swanson

Black walnut (Juglans nigra) is a separate species native to North America, and it differs substantially from the familiar walnut (Juglans regia) in composition and traditional use. In herbal practice it is not the kernel that is valued but the outer covering: the hull and the green husk. This is where the tannins, bitter compounds and other phytocompounds are concentrated, and they are what gives rise to interest in this plant.

Swanson capsules contain hull powder at a dose of 500 mg. It is a single-ingredient product with no added plant extracts or supporting active ingredients. This format suits those who prefer single-herb supplements and want to know exactly what they are taking, without complex multi-ingredient blends.

It is important to understand that this is a food supplement, not a medicine. The product is not intended for diagnosing, treating or preventing any disease.
