Chitosan or/and algal polysaccharide composite biological matrix liquid dressing gel preparation and preparation method thereof

The invention relates to a chitosan or/and algal polysaccharide composite biological matrix liquid dressing gel preparation. The composite biological matrix liquid dressing gel preparation is characterized by comprising main materials and auxiliary materials. The main materials include the following components of 0.5-5wt% of chitosan; 0.00-3.0wt% of algal polysaccharides; 0-2wt% of a concentratedschizonepeta extraction solution; 0-2wt% of a concentrated sophora flavescens extraction solution; 0.5-2wt% of hydrolyzed pearl powder; 0.05-0.5wt% of borneol; and 50,000-100,000 IU of epidermal growth factors. The auxiliary materials include a stabilizing agent and an emulsifying agent, wherein the emulsifying agent is at least one of glycerol, carbomer, EDTA, ethylene glycol, triethanolamine andbenzoic acid. The gel preparation has the characteristics of broad-spectrum antibiosis, necrotic tissue removal, tissue regeneration, rapid repair, safety, stability, efficient slow release and the like, and achieves the effe
