Biological Activities
Compounds
Conditions
Encephalartos villosus methanol extract demonstrates significant antifungal potential by treating Candida glabrata clinical isolates. This plant extract also serves as an effective treatment for invasive candidiasis, as evidenced by its impact on systemic infections. In vivo studies show that it treats the congestion of the glomeruli and tubules within kidney tissues. Furthermore, the extract helps mitigate inflammation by treating the proinflammatory cytokine tumor necrosis factor-alpha. Finally, Encephalartos villosus contributes to tissue repair by treating abnormal collagen fibers.
Preparations
Parts used
Encephalartos villosus serves as a promising source of natural therapeutic compounds, particularly through its leaf components. Recent studies have focused on utilizing a methanol extract derived from these leaves to combat resistant fungal infections. Specifically, the extract has demonstrated significant antifungal potential against Candida glabrata clinical isolates both in vitro and in vivo. Research indicates that the leaf extract works by affecting the fungal cell wall and downregulating key efflux pump genes. Furthermore, animal models show that the extract can reduce kidney tissue inflammation and congestion caused by systemic infection.
