The effect of combining humic and fulvic acids poultice on wound healing in male rats

Abstract

Background: Finding new compounds to accelerate wound healing is critical today. Humic substances or fulvic acid each have anti-inflammatory properties. Aims and Objectives: The purpose of this study is to determine the effects of poultice 0.5% containing humic and fulvic acids on wound healing in male rats. Materials and Methods: An animal model was arranged by making a full-thickness skin wound was created in each rat. Animals were randomly divided into control, sham, and treatment groups. To investigate the effect of humic and fulvic acids combining poultice, the wound area and histological analyses of the number of inflammatory cells, fibroblasts, and angiogenesis were evaluated for 21 days. Results: The animals in the treated group showed higher wound healing percentage, angiogenesis, and fibroblast distribution compared with the control (P < 0.001). Moreover, the topical administration of humic and fulvic acids 0.5% poultice decreased the mean number of inflammatory cells significantly than the other groups (P < 0.001). Conclusion: The topical administration of a poultice containing humic and fulvic acid accelerated wound healing by increasing angiogenesis and fibroblast and reducing inflammatory cell distribution in a rat model.
