Description
Summary:	Healthcare professionals must take special care of wounds to avoid serious complications such as infections, lengthy healing periods, and even amputations. This study aimed to design and manufacture a self-healing bioabsorbable polymeric-based wound dressing with antibacterial growth and improved wound healing properties. Gel-based mixtures were successfully made up of 5wt% chitosan with properties that inhibit bacterial growth in 5–20wt% polyvinyl alcohol (PVA) and called the “pure mixture”. It was observed that the mixture of 5wt% chitosan into 10wt% PVA resulted in the most controlled viscosity and appropriate gel texture for wound healing. The measured viscosities of 5wt% chitosan and 10wt% PVA were 235 and 531 Pa·s, respectively. A microscopic examination confirmed that the addition of chitosan into PVA successfully inhibited bacterial growth. Another gel-based mixture, named the “additive mixture”, was also investigated using the optimized preparation condition of 5wt% chitosan in 10wt% PVA with the incorporation of some traditional herbs in powder form, namely frankincense, myrrh, and alum stone. Microscopic examination proved that the addition of traditional herbs into the chitosan/PVA mixture inhibited some bacterial growth. A comparison of the wound healing performance of the pure mixture gel and additive mixture gel was conducted using rats. The pure mixture gel produced a faster healing rate and a lower level of inflammation than the additive mixture gel.
