Bulk Black walnut hull cut & sifted

Black walnut hulls contain a naturally occurring pigment called juglone, which is chemically similar to the pigment found in henna leaf. This compound contributes to the hull’s deep brown coloration and has made black walnut a traditional material for natural dyes. Black walnut hulls are commonly used in cosmetic and personal care applications such as natural hair coloring products and self-tanning formulations. They are also widely used to produce rich brown dyes for ink, wool, and other natural textiles.
