1. A hemostatic chitosan material in granule or particle form having a density between about 0.25 to 0.60 g/cm3 and a granule or particle diameter of about 0.9 mm, wherein said granules or particles are produced by freeze-drying a frozen matrix of chitosan, heat-compressing said matrix, and then granulating the compressed matrix. |
