Uncontrolled hemorrhage remains a critical threat in trauma and surgery. This study developed a novel hemostatic composite by encapsulating Peganum harmala L. seed extract (PH) with known hemostatic properties into lipid nanocapsules (PH-LNCs) and then embedding them within a polyvinyl alcohol-chitosan-polyethylene glycol-glycerol (PVA-CS-PEG-G) matrix.

The HG matrix of the proposed skin substitute is composed of gelatin (GE) and sodium alginate (SA), and incorporates hyaluronic acid (HA) as a key component of the natural ECM, as well as the antimicrobial extract (PE). This HG nanocomposite was cross-linked by the biocompatible -(3-(dimethylamino)propyl)-'-ethylcarbodiimide hydrochloride (EDC) cross-linker, and was reinforced with fragmented -ferulic acid (FA)-loaded cellulose acetate/polycaprolactone (PCL/CA) NFs.
