Topical application of Mentha piperita essential oil accelerates wound healing in infected mice model

Area of Science:

• Pharmacology
• Microbiology
• Dermatology

Background:

• Infected wounds pose significant clinical challenges.
• Exploring natural compounds for wound healing is crucial.
• Mentha piperita essential oil (M. piperita) has potential antimicrobial and anti-inflammatory properties.

Purpose of the Study:

• To evaluate the efficacy of M. piperita essential oil ointments in accelerating wound healing.
• To assess the impact of M. piperita on bacterial infection and inflammatory markers in wound models.
• To investigate the molecular mechanisms underlying M. piperita's wound healing effects.

Main Methods:

• Infected mice models with Staphylococcus aureus and Pseudomonas aeruginosa were used.
• Wounds were treated with varying doses of M. piperita ointments.
• Assessed parameters included tissue bacterial count, histological changes, and gene expression (IL-10, TNF-α, TGF-β1, IL-1β, CCL2, CXCL1, VEGF, FGF-2).

Main Results:

• M. piperita treatment significantly reduced tissue bacterial load, edema, and inflammation.
• Enhanced fibroblast migration, collagen synthesis, and re-epithelialization were observed in treated groups.
• Upregulation of CCL2, CXCL1, IL-1β, TGF-β1, and IL-10, and downregulation of TNF-α, VEGF, and FGF-2 gene expressions were noted.

Conclusions:

• M. piperita essential oil demonstrates significant potential for treating infected wounds.
• The oil promotes wound healing by modulating inflammatory responses and enhancing tissue regeneration.
• Further research into M. piperita as a therapeutic agent for wound infections is warranted.
