1. A process for the preparation of a composition for sealing and healing wounds which comprises adding a mixture of (1) a fibrinogen component containing fibrinogen, factor XIII-containing fibrinogen or a mixture thereof, and (2) a thrombin component containing thrombin, a substance which liberates thrombin in the presence of body fluid, or a mixture of such substances, to an organic solvent, in the absence of water, homogenizing the resulting slurry to form a homogeneous suspension of the mixture in the solvent, applying the said suspenion to one or more surfaces of a collagen carrier and evaporating the organic solvent, whereby particles of the said mixture remain adhering to the surface or surfaces of the collagen.
