Hemp hurds, also known as shives or hemp wood, are an agricultural product made from hemp. Hurds consist of the woody inner portion of the hemp stalk, broken into pieces and separated from the fiber in the processes of breaking and scutching and correspond to the shives in flax, but are coarser and usually softer in texture. Hurds have traditionally been a by-product of fiber production.
