ABSTRACT
Plants of the Asteraceae family have been traditionally used as medicinal plants. The species Achyrocline satureioides and Achyrocline alata present anti-inflammatory properties and great chemical similarity. However, no study has been performed to evaluate the influence of these plants on skin wound healing in vivo. Here, we have assessed the effect of these plants extracts on skin wound healing in mice. Mice were randomly arranged into three groups (n = 10), an injury was performed on the dorsal area of the animals, which received the following topical treatment group 1, control (ointment base); group 2, A. satureioides extract; group 3, A. alata extract. The solution for treatment was prepared as 10% (w/w) concentration. The wound area was measured on days 1, 4, 9, 15 and 17 after treatment and tissues of local lesion were collected on the ninth day for histological analysis. A. alata was more effective since it induced earlier wound closure associated with decreasing initial inflammatory response, faster reepithelialization and collagen remodeling. A. satureioides improved the collagen renovation, but induced slower closure, which may be due to different concentrations of phenolic compounds among the plants here studied. Both plants did not alter the ultrastructural characteristics of cells in the healing process. In conclusion, our findings suggest the potent wound healing capacity of A. alata extracts, as demonstrated by more efficient and faster induction of wound closure. We believe this plant is a potential wound healing treatment for humans and further studies are necessary to assess its clinical practice.
