Effects of Medicinal Plants Extracts in Healing Split-Thickness Skin Graft Donor Site Wounds: A Systematic Review of Randomized Clinical Trials

Abstract

The literature on Split-Thickness Skin Graft (STSG) donor site dressings has not yet identified an ideal dressing, and most products tested by researchers for wound dressing are prohibitively expensive in Low- and Middle-income settings. Clinical trials using biological dressings have offered an alternative option for managing STSG donor sites wound. The aim of this systematic review is to find evidences regarding the effectiveness of medicinal plants on STSG donor site wound healing. A total of 249 papers were identified in the initial search. After removing duplicates and applying the inclusion and exclusion criteria, 6 Randomized Clinical Trials were deemed relevant and included in the final review. Over twenty years four medicinal plants have entered clinical trial to enhance STSG donor site wound healing. The medicinal plants reviewed have large effect size regarding time to complete wound healing and wound score. However, the effect size of Aloe vera regarding time to complete wound healing and pain control vary from study to study. No patient quality of life was assessed neither cost-effectiveness of these products. Medicinal plants are potential cost effective antimicrobial and wound healing products for STSG donor site wound dressing. However, more clinical researches including patient quality of life among outcome measures are needed.
