Topical aqueous extract of Ephedra alata can improve wound healing in an animal model

Abstract

Purpose: Ephedra alata (E. alata) is perennial tough shrub plant that grows in Palestine and other regions. It is used often in folk's medicine for the treatment of various diseases. In this project, E. alata extract was tested for its ability to improve wound and burn healing. Methods: An aqueous extract of E. alata was prepared and underwent several phytochemical analyses for the presence of the major classes of phytochemical compounds. After that, a polyethylene glycol-based ointment containing the extract of E. alata was prepared and its wound and burn healing activities were tested in-vivo using an animal model for deep wound and full thickness skin burn. The effect was compared against a placebo ointment. Skin biopsies were evaluated by a blinded clinical histopathologist, in addition to digital analysis. Results: Phytochemical analysis demonstrated the presence of the major classes of phytochemical compounds in the prepared extract including flavonoids, alkaloids, phytosteroids, phenolic compounds, volatile oils and tannins. As compared to placebo ointment, E. alata ointment significantly improved the healing of the wound ulcers, whereas it showed no advantage on the quality of the healing of burn ulcers. Conclusion: E. alata extract is rich in phytochemical compounds and can improve wound healing when applied topically.
