Plant Extracts as Modulators of the Wound Healing Process-Preliminary Study.

Area of Science:

• Pharmacology
• Natural Product Chemistry
• Wound Healing Research

Background:

• Chronic wound treatment presents significant challenges in modern medicine, leading to prolonged recovery and high costs.
• Herbal products offer potential therapeutic benefits for chronic wounds due to their diverse pharmacological activities and effects on healing phases.

Purpose of the Study:

• To evaluate the capacity of specific plant extracts to modulate wound healing processes.
• To assess antimicrobial, antioxidant, cytotoxic, and collagen-stimulating properties of selected botanical extracts.

Main Methods:

• Antimicrobial activity was determined using Minimum Bactericidal Concentration (MBC).
• Antioxidant capacity was assessed via ABTS and DPPH assays.
• Cytotoxicity was evaluated using the MTT test, and wound closure was studied using the scratch wound assay.
• Collagen synthesis stimulation was quantified, comparing extract efficacy to ascorbic acid.

Main Results:

• R. canina and V. venifera extracts demonstrated bactericidal activity against P. aeruginosa and S. aureus.
• V. vinifera extract exhibited potent antioxidant activity in both ABTS and DPPH assays.
• Certain extracts, including V. vinifera, significantly stimulated collagen synthesis in vitro.

Conclusions:

• Preliminary findings suggest that selected plant extracts possess properties that can modulate wound healing.
• Further in vivo investigations are warranted to confirm the therapeutic potential of these natural agents for chronic wound management.
