Hydrogel-Plant Extract Composites in Wound Healing

Abstract

Hydrogels are three-dimensional, hydrophilic polymer networks that retain significant amounts of water and are used extensively in wound healing due to their biocompatibility and flexibility. Traditional chemical crosslinking methods can involve toxic agents, making plant extracts a promising natural alternative. These extracts, rich in bioactive compounds such as phenolics, flavonoids, alkaloids, and terpenoids, provide additional therapeutic benefits including anti-inflammatory, antimicrobial, and antioxidant activities. The incorporation of plant extracts into hydrogels enhances their therapeutic potential by offering properties such as increased mechanical strength, improved stability, and controlled release of bioactive compounds. This integration supports sustainable and eco-friendly practices in biomedical materials. Clinical studies have shown that hydrogels enriched with plant extracts can accelerate wound healing, improve tissue regeneration, and address challenges such as diabetic wounds. Future research should focus on optimizing these formulations, developing standardized methods for incorporating plant extracts, and conducting large-scale trials to confirm their efficacy. Overall, hydrogel-plant extract composites represent a significant advancement in wound care technology, merging the benefits of natural compounds with the versatility of hydrogels to offer effective and environmentally friendly solutions for modern wound management.
