Anti-Inflammatory and Regenerative Properties of Herbal Extracts: Wound Management in Equine Models.

Abstract

Introduction: Wound management presents significant challenges, requiring effective treatments. Herbal extracts have been traditionally used to support healing due to their anti-inflammatory, antimicrobial, and cell-regenerative properties.

Methods: This study aimed to evaluate the therapeutic efficacy of Pau D'Arco (Tabebuia), Yarrow (Achillea millefolium), Gotu Kola (Centella asiatica), Figwort (Scrophularia nodosa), and Broadleaf (Plantago major) extracts, both individually and combined, on wound healing in vitro and in vivo in equine models. In vitro tests using human macrophages and keratinocyte cell lines to assess cellular responses such as cytokine secretion and phagocytic activity under simulated inflammatory conditions. Additionally, pilot case studies on equines with open wounds provided practical insights into the extracts' healing capabilities.

Results: MTT assay was used to assess cytotoxicity. The extracts did not significantly affect the viability of HaCaT or THP-1 cells. The herbal extracts reduced IL-8 levels and increased phagocytic activity in macrophages, indicating an ability to modulate inflammatory responses. In vivo, the extracts were well tolerated and associated with supported healing in equines. These effects were suggested to be attributed to the synergistic actions of the herbal components.

Conclusion: These findings suggest that the herbal extracts may be useful for supporting wound healing. Their natural anti-inflammatory and healing properties could provide an additional option alongside traditional wound management approaches.
