Abstract: The present technology refers to medicine, namely hemostatic and wound healing agents, and can be used to stop bleeding of various severity, including venous, as well as to heal wounds and cuts obtained as a result of mechanical action on the epidermal and muscular layers of tissues. For this, a hemostatic agent containing an active gelling agent based on chitosan and/or its derivatives is used, characterized in that it contains chitosan, its salts and/or its derivatives in the form of a gel having a three-dimensional crosslinked structure as a polymer matrix and components of natural thrombus formation in the form of organic calcium compounds, organic acid and water coordinated on this matrix at a certain ratio of components.
