Medical training kits and methods include a simulated liquid blood which simulates mammalian whole blood and a simulated hemostatic component. The simulated liquid blood includes a gellable component, and a simulated hemostatic component includes a gelling agent. The gelling agent causes the gellable component in the simulated liquid blood to form a mass of semi-solid or solid material in response the simulated blood being brought into contact therewith to thereby simulate blood clotting. In certain embodiments, the gellable component is chitosan and/or an alginate compound and the gelling agent is at least one compound which causes the gellable component to desolubulize, polymerize, complex, precipitate, cross-link and the like so as to form a semi-solid or solid mass of chitosan in response to physical contact between the simulated blood and the simulated hemostatic agent.
