Advanced Natural Therapeutics and Delivery Strategies for Diabetic Foot Ulcers: A Mini Review

Abstract

Diabetic foot ulcers (DFUs) are a severe complication of diabetes mellitus with complex pathophysiology. Conventional therapies often lead to poor healing and high recurrence. This mini-review highlights the promise of advanced natural therapeutics and delivery strategies for DFU management. We focus on bioactive natural compounds, such as ginsenosides, astragalus polysaccharides, and resveratrol, that target critical processes like hyperglycemia, vascular impairment, and oxidative stress by modulating key signaling pathways. To improve bioavailability, innovative delivery systems including nanotechnology and nitric oxide-releasing platforms have been developed, enabling sustained release and enhanced healing. Clinical evidence shows promising results, such as shortened healing time and improved ulcer closure rates, supports the translational potential of standardized natural formulations. Moving forward, priorities should focus on standardizing natural formulations, optimizing delivery, and conducting rigorous clinical trials. With continued innovation, natural therapeutics hold significant potential to improve wound healing, reduce amputations, and enhance the quality of life for DFU patients.
