SCOPING REVIEW: POTENTIAL WOUND HEALING EFFECT OF EUPHORBIA HIRTA (ARA TANAH) BASED ON IN VIVO MODELS

Abstract

Wound management is important as it helps to promote healing without microbial infection. Euphorbia hirta, a species of Euphorbiaceae family, also known as Ara tanah among Malaysians, is traditionally used to promote wound healing where its poultice is applied to the sores on the legs, bruises and wounds. Several reported pharmacological properties including antioxidant, antimicrobial, antidiabetic, anti-anaphylactic activities have been reported on this plant. The aim of this review was to evaluate the wound healing effects of E. hirta. Information involving only in vivo studies on wound healing effect of E. hirta was searched using electronic databases. The electronic databases include PubMed, Google Scholar, Ovid, CENTRAL, LILACS, and ClinicalTrials.gov from year 1962 to 2020. A total of five out of 70 studies were included and assessment was made. All included articles studied different wound models in rats. All showed significant wound healing activity with different mechanism of action for incision, excision and dead space wound. Quality assessment of the included studies suggested that experimental animal study design can be improved. It can be concluded that E. hirta displayed potential as a wound healing agent in vivo studies although further research on structureactivity relationship of compounds responsible for the wound healing effect and toxicological studies before it can proceed to clinical studies.
